Abstract I compared pesticide levels in the eggs of Loggerhead Shrikes (Lanius ludovicianus) collected from Illinois in 1995–1996 with those reported for the state in 1971–1972. Pesticides were detected in 19 of 21 (90%) eggs from 1995–1996. DDE was the most frequently detected pesticide, occurring in 17 of 21 eggs. DDT was the second most frequent pesticide detected and was found in nine eggs. Mean DDE levels in shrike eggs from 1995–1996 were 79% lower than in eggs from 1971–1972. Unlike most bird species for which pesticide levels are known to have been reduced (whose populations have tended to increase), Loggerhead Shrike populations have declined during the period in which pesticide levels within their eggs has been reduced. These data suggest that organochlorine pesticides are likely not driving current Loggerhead Shrike declines in Illinois. Los Pesticidas Organoclorados no Están Implicados en la Disminución de Lanius ludovicianus Resumen. Comparé los niveles de pesticidas en huevos de Lanius ludovicianus colectados en Illinois entre 1995 y 1996 con los niveles de pesticidas reportados para el estado entre 1971 y 1972. Se detectaron pesticidas en 19 de 21 huevos (90%) entre 1995 y 1996. El pesticida detectado con mayor frecuencia fue DDE, el cual se detectó en 17 de 21 huevos. DDT fue el insecticida detectado con la segundo mayor frecuencia, y fue encontrado en nueve huevos. Los niveles medios de DDE encontrados en los huevos de 1994– 1996 fueron un 79% más bajos que en huevos de 1971–1972. A diferencia de la mayoría de las especies de aves para las cuales se sabe que los niveles de pesticidas se han reducido (cuyas poblaciones han tendido a aumentar), las poblaciones de L. ludovicianus han disminuido durante el período en que los niveles de pesticidas hallados dentro de sus huevos han sido reducidos. Estos datos sugieren que probablemente los pesticidas organoclorados no están causando la disminución actual de las poblaciones de L. ludovicianus.

It has been speculated for many years that crop yield diminution may be due to the possible adverse effects of pesticidal sprays during the blooming period on pollen germination and fruit set. To realize the toxicity of pesticides on the reproductive physiology of mango, pollen germination, both in vitro and in vivo, under the constrain of pesticides were conducted. The results showed that among all the pesticide tested, Lannate and Tamaron were the least toxic ones to mango pollens germinated on agar medium incorporated with pesticides. Pesticides when sprayed on the surface of germination medium had strong adverse effect on pollen germination. Except for Tamaron, the fertilization of mango flowers were extremely sensitive to pesticidal sprays 2 hours before or 4 hours after hand pollination. Fertilization and initial fruit set were not or less influenced by pesticides for flowers sprayed 24 hours after pollination.

Considering agricultural hub Indian farmers used pesticides as plant protection agent for boosting yield. Use of pesticides causes a range of human health problems like cancers and many others. Compared to the general population, who is exposed to substantially lower amounts of pesticide residues through food and water, agricultural worker have a higher risk of developing health issues as a result of pesticides. This article will not only enable the provision of key data about the carcinogenic risk related to the duration,type & degree of pesticidal exposure in all age groups, but will also aid in determining the risk of pesticidal residues in food & water which demand timely assessments.

Pesticides kill neurons, but the mechanism leading to selective dopaminergic loss in Parkinson’s disease (PD) is unknown. Understanding the pesticide’s effect on dopaminergic neurons (DA) can help to screen and treat PD. The critical uptake of pesticides by the membrane receptors at DA is hypothesized to activate a signaling cascade and accelerate degeneration. Using MPTP as a reference, we demonstrate the mechanisms of eleven crucial pesticides through molecular docking, protein networks, regulatory pathways, and prioritization of key pesticide-regulating proteins. Participants were recruited and grouped into control and PD based on clinical characteristics as well as pesticide traces in their blood plasma. Then, qPCR was used to measure pesticide-associated gene expression in peripheral blood mononuclear cells between groups. As a result of molecular docking, all eleven pesticides and the MPTP showed high binding efficiency against 274 membrane receptor proteins of DA. Further, the protein interaction networks showed activation of multiple signaling cascades through these receptors. Subsequent analysis revealed 31 biological pathways shared by all 11pesticides and MPTP that were overrepresented by 46 crucial proteins. Among these, CTNNB1, NDUFS6, and CAV1 were prioritized to show a significant change in gene expression in pesticide-exposed PD which guides toward therapy.

Despite being acknowledged globally as one of the primary environmental pollutants, pesticides appear as one of the toxic compounds that are available purposefully to be used in controlling pests and vectors, especially in agricultural areas [1]. Nevertheless, pesticides have been discovered to be associated with a broad scope of pathologies, especially with Parkinson’s disease (PD) Most previous studies could not determine a significant positive relationship due to the discrepancies in their methodologies. Based on data published by the Department of Statistics Malaysia, the proportion of citizens with PD in Malaysia is anticipated to grow five-fold by 2040, from an estimated 20,000 to 120,000 cases [2].
Hence, this study is employed to deliver an up-to-date systematic review and meta-analysis regarding pesticide exposure and PD which will be based on the highest quality of evidence along with a broader extent of study designs that encompass cohort, case-control and cross-sectional studies to identify the significant link between them. The objective of this study was to find out whether there is an increased risk of PD among adults with occupational exposure to pesticides and to determine the pesticides that are associated with PD.
In formulating the research question, the P (population) E (exposure) C (control) O (outcome) model was used. The search was done from databases such as Google Scholar, Pubmed and Science Direct. The key points used were as followed: “occupational” OR “professional” OR “work-related” OR “job-related” OR/AND “pesticidal” OR “pesticide's” OR “pesticides” OR “pesticide” AND “Parkinson disease” OR “Parkinsons disease” OR “Parkinson's disease” OR “Parkinson” OR “Parkinsons” OR “Parkinson’s”. Meta-analysis was directed by utilizing the Review Manager 5 software to inspect the data regarding work-related pesticide acquaintance and the development of Parkinson’s disease based on all included studies of selected characteristics.
The systematic review encompassed 26 studies where 23 of them displayed a significant association between occupational exposures to pesticides that increased the risk of developing PD. The meta-analysis also supported the hypothesis of this study where work-related pesticide acquaintance showed 89% higher odds to develop PD [OR = 1.89, 95% CI (1.63 to 2.20)]. For specific types of pesticides, organophosphorus contact revealed the strongest association with 89% higher odds [OR = 1.89, 95% CI (1.35 to 2.64)] followed by insecticides contact with 86% higher odds [OR = 1.57, 95% CI (1.58 to 1.92)], organochlorine exposure with 71% higher odds [OR = 1.71, 95% CI (1.21 to 2.41)], fungicides acquaintance at 42% higher odds [OR = 1.42, 95% CI (1.33 to 1.51)] and herbicides contact with 23% higher odds [OR = 1.23, 95% CI (1.03 to 1.46)] to establish PD (Table 1).
Overall, occupational pesticide contact exhibited an increased risk of PD with organophosphorus displaying the strongest association among other specific types of pesticide. The theory concerning the specific kind of pesticides that can lead to PD is inconsistent where it is immensely dependent upon their mechanism of toxicity and chemical composition as well as its explicit biochemical passageways which up until this moment is not yet being fully understood. Hence, the result of this study can supplement advanced knowledge in the literature where it can be utilized to govern further studies and implementations in the future to improve the safety and health of the workers who are involved with pesticides’ application day to day as well as the health of the public. Therefore, a safer class of pesticides may also be invented consequently. On the other hand, it may also aid in future studies to find out the specific biomarkers or reliable tools which can measure the causal relationship between pesticides’ acquaintance and PD more accurately. Thus, the forthcoming studies that can count on more unbiased and quantifiable approaches regarding the evaluation of pesticides’ acquaintance and PD must be fostered.

The use of pesticides is accompanied by a number of environmental and agrotechnological problems. Many pesticides do not degrade and stay in the soil for years and have low selectivity. Massive application of pesticides with non-selective nature of action caused a gradual increase of resistance in pests due to persistent inherited changes in their DNA. This affects the efficiency of growing agricultural plants and pollution of the environment and food. Computational biology methods, which are actively developing all over the world, can help to solve this problem. Despite the fact that in Russia bioinformatics methods are used to study plant genes of animals, metagenomes of microorganisms, there are no own databases and specialized computer applications for such research and pesticide modernization. Development of domestic similar bioinformatics tools is also an urgent task. The article highlights the problem of creating new effective and environmentally friendly pesticides. The methods of bioinformatics that can be used in the research and development of pesticides are given. The stages of creating new pesticides by bioinformatics methods (review of databases, modeling of molecules, modeling of the interaction of a pesticide with a target, prediction of biological activity) are considered. A description is given of the methods for optimizing the molecular framework of pesticides, which is a change in the carbon skeleton in order to search for new active compounds and screen out many similar compounds in the chemical space. Foreign web resources used to assess the presence of pesticidal properties in substances, such as toxicity, metabolism and physico-chemical properties, and their subsequent registration as pesticides are given.

Pesticides pose a significant risk to humans and the environment. This paper analyzes the measures used to manage pesticides in Malawi. Malawi’s regulatory authority of pesticides, the Pesticides Control Board (PCB), faces a number of challenges including lack of facilities for analyzing pesticides and inadequate personnel to conduct risk assessment of pesticides. The PCB needs to provide access to information and opportunities among the public to make contributions regarding requirements, processes and policies for assessing pesticide risk and efficacy. There is also a need to enhance the capacity of PCB to assess pesticide poisoning in workers, monitor pesticide residues in food and environmental contamination, as well as to control the illegal importation and sale of pesticides. Just like in other countries such as South Africa, India and Sri Lanka, Malawi urgently needs to implement measures that can restrict the importation, production, sale and use of very toxic pesticides. Malawi also needs to develop measures for the effective management of pesticide waste containers as well as obsolete pesticides, where potential solutions include reducing the purchase of (unneeded) pesticides, treatment of obsolete pesticides in high-temperature cement kilns, as well as requesting pesticide dealers to adopt life-cycle management of their products.

Pesticide’s manufacture, use, storage and disposal should be strictly regulated to reduce its negative effects on environment and public health. The reports show that the pesticide use increasing every year globally and currently its national use in average is 0.39 kg a. i/ha. It has been found that the quantity of consumption of pesticide in Nepal in agricultural field is very low in comparison to the other countries of the globe but due to its haphazard use in some commodity and ignorance of waiting period after its application has increased the risk of the exposure of farm families to pesticides and intake of pesticides by consumers, which are becoming major health threat.Journal of Health Promotion Vol.6 2008, p.28-36

Globally more than half of the pesticides are utilized in Asia. India stands 12th in pesticide use globally and 3rd in Asia after China and Turkey. In present study, the data of different types of pesticides, pesticide use pattern and detailed pesticide consumption of the India and world were collected, organized and summarized. Agriculture is the most important sector of the Indian economy providing employment and livelihood to nearly 70% of the total population. And pesticides are an integral part of modern agriculture. Insecticides, fungicides and herbicides are commonly used for pest control in agriculture. However, insecticides form the highest share in total pesticide use in India. India share only1% of the global pesticide use. India has utilized around 58160 tonnes of pesticide in 2018. Per hectare application rate of pesticide was 0.31 kg in 2017. Despite a low per hectare use of pesticides in India, their injudicious use has led to the presence of residues in both biotic and abiotic sections of the environment. The advance research and development in the field of bio-pesticides applications greatly reduce the environmental pollution caused by the chemical synthetic insecticides residues and promotes sustainable development of agriculture. In India numerous bio-pesticides presently being developed may be exceptional replacements to chemical pesticides. There are many eco-friendly plant based and microbial bio-pesticides available in the market. Bio-pesticides consumption is only 8% in India. For sustainable agricultural development and to protect environment from adverse effect of chemical pesticides, formulation and utilization of bio-pesticides should be prompted.

Many households in developing countries routinely use pesticides without any safety considerations. The objective of this study was to determine types of pesticides and pesticide-use practices of the residents, to determine self-reported adverse effects resulting from pesticide use and to assess the impact of educational intervention on pesticide use behavior in the study area. Commercially available pesticide samples were collected from pesticide vendors in the area. Pre -tested questionnaires were distributed to 375 family heads. Data was expressed as frequency and percentages.Educational intervention on safe pesticide use was carried out. Pre and post intervention behavior were compared using paired t test. Relationship between demographic variables and pesticide use practices were explored using Chi Square statistics. A p value of less than 0.05 was considered significant. Prevalent pests were mosquitoes, cockroaches, rats, bedbugs, ants, termites, houseflies, ticks and scorpion. The major constituent of pesticides in this environment was Dichlorvos (DDVP). Many commercially available pesticides were unlabeled. Nearly half, 48.8% had used pesticides in the home. More than three quarters, 78.7% indicated that they read instructions before using pesticides. More than one third, 36% had experienced health problems attributed to pesticide use. Many locally available pesticides were unlabeled. Majority of labelled pesticides contained mainly Diclorvos (DDPV). Unsafe pesticide handling practices were common. The most common self -reported adverse effect was respiratory symptoms. Educational intervention increased in the proportion of respondents that used of non-chemical methods and adopted safer pesticide use practices.

There are many approaches of pesticide risk assessment. Despite their variation in difficulty and information complexity, all of them are intended to predict the actual pesticide risk as accurately as possible, i.e., to predict the behavior and hazard of a pesticide in the environment with high precision. The aim of this study was to develop a risk indicator of pesticide’s negative impact on soil and aquatic organisms. The developed pesticide risk indicator constitutes the sum of points of acute toxicity exposure ratio, long-term toxicity exposure ratio, and the bioconcentration factor. To develop the indicator, mathematical models were used; the input data included the soil and climate conditions of a specific region. Combining the data of pesticide toxicity in the environment allowed for a more accurate risk assessment in terms of using plant protection products. The toxicity and behavior in soil and water of 200 widespread pesticides were studied. It could be concluded that a mathematical model, PEARL 4.4.4, calibrated for region-specific soil-climate conditions, provides a relevant description of the natural translocation and decomposition of pesticides in soils. In addition, the output data of this model can be applied to calculate the risk indicators. The combination of these parameters with pesticide toxicity for non-target groups of organisms allows the risk indicator to be a universal tool for predicting the negative impact of pesticides on the environment at the regional level.

This study reported knowledge, attitude and perception of pesticide use among farmers to determine the level of farmers’ education on use and handling of pesticides. Data on pesticide types purchased were collected from pet-shops and agro-allied stores in three states in Nigeria. Questionnaires were administered to 100 farmers within Ibadan (Oyo State) to determine specific pesticides used, handling procedures adopted by farmers, protective measures employed and perception of toxic potentials of pesticides to human handlers and exposed animal. Survey reports showed majority used DDVP, 34% of farmers were uneducated, while 42%, 18% and 6% had primary, secondary and tertiary education, respectively. About 63.5% had been farming for 11-20years, 75% kept poultry while others kept sheep/goat and cattle. About 75% sought information from extension agents on pesticide use. The farmers were aware pesticides pose health hazards to animals but only 75% knew it could affect humans, 40% knew of pesticide withdrawal period with diverse opinions on route of pesticide poisoning. The study concluded that farmers and pet-owners in Southwest Nigeria use pesticides unethically and majority are unaware of toxicity and hazards of misuse and handling of pesticides, consequently exposing themselves and animals to hazardous and toxic pesticide levels. Legislations on pesticides enacted to prevent pesticide abuse should be enforced and awareness campaigns intensified to enlighten farmers and pet-owners on potential hazard pesticides pose to themselves, animals and environment. This would eventually prevent unnecessary exposure through misuse/mishandling of pesticides and create a safer ecosystem at large.

Pest management is being confronted with immense economic and environmental issues worldwide because of massive utilization and over-reliance on pesticides. The non-target toxicity, residual consequence, and challenging biodegradability of these synthetic pesticides have become a serious concern, which urgently requires the alternative and prompt adoption of sustainable and cost-effective pest control measures. Increasing attention in environmental safety has triggered interest in pest control approaches through eco-friendly plant-based pesticides. Botanical pesticidal constituents are effective against myriads of destructive pests and diseases. More importantly, they are widely available, inexpensive, accessible, rapidly biodegradable, and have little toxicity to beneficiary agents. The phytochemical compositions in diverse plant species are responsible for their varying mechanisms of action against pests and diseases. However, difficulties in their formulation and insufficient appropriate chemical data have led to a low level of acceptance and adoption globally. Therefore, the review seeks to highlight the status, phytochemical compositions, insecticidal mechanisms, and challenges of plant-based pesticide usage in sustainable agricultural production.

Pesticides are widely used to reduce crop losses due to pests. This study (an initial part of a project on risk assessment and biomonitoring) deals with pesticide use patterns in the South-West, Cameroon. This descriptive and cross-sectional study was done using questionnaires randomly administered to 137 respondents. Twenty-one crops were recorded in the area with a total of 107 pesticides (60 active ingredients) used. Three illegally used pesticides were recorded (lindane, dimethoate and malathion). Application of pesticides in combination was quite common (42.3%). Pesticide application was mainly manual using a sprayer (96.4%) with 54% of users experiencing health problems post-application. Because of the lack of funding and training, 19.7% sprayed pesticides without protection. For the Restricted Entry Interval (REI), 43.1% entered the field in less than 12h after pesticide application. The correlation between the REI and the number of symptoms was negative and non-significant (R=-0.07, p≥0.05). The main place to store pesticides was the house (57.7%) with the exception of CDC where pesticides were kept in a pesticide store. Some respondents (54.7%) said they hadn’t received any training on pesticide application while 20.4 % of respondents failed to follow recommended doses. Surface water around farms was used by 62.1% of pesticides users for domestic purposes. Some farmers (46.7%) have once heard about pesticide related accident while 14.6% suffered from pesticide intoxication, the prevalence being significantly higher in males (p<0.05). Therefore, there is a need to regulate the pesticides sector, assess ecological risk and the bioaccumulation potential of these pesticides as well as their ability to hindrance water quality and biota.

Improvement in pesticide application and efficiency structure has long been recognized as having great significance in reducing pollution, ensuring food safety, and promoting green agricultural development. Based on theoretical analysis, using the survey data of 766 farmers in key tea areas in Shaanxi, Sichuan, Zhejiang, and Anhui provinces in China, the study empirically analyzes the influence of market incentives and livelihood dependence on farmers’ multi-stage pesticide application behavior. More specifically, the study employed ordered probit analysis to craft its findings. The dependent variable of this study is the multi-stage pesticide application problem of farmers, and the core independent variables are market incentives and livelihood dependence, and the judgment is based on the core variable coefficients of the econometric model of farmers at each stage. The study found the following: (i) Market incentives significantly prompted some farmers to give up synthetic pesticide application and farmers tend to choose green pesticides in the type of pesticide application. (ii) Livelihood dependence meant that the proportion of tea income significantly prompts farmers to apply pesticides, and also creates a tendency for farmers to choose green and low-toxic pesticides in the type of pesticide application. The planting period tends to have a moderate impact on applying green and low-toxic pesticides. (iii) The interaction term of market incentives and the proportion of tea income has no significant impact on farmers’ multi-stage pesticide application behavior. The interaction term of market incentives and planting years has impacted negatively on whether farmers apply pesticides, and has no significant impact on farmers’ choice of pesticide application types, but makes farmers increase the amount of green and low-toxic pesticides. (iv) The education level of the household head significantly promotes farmers to choose green and low-toxic pesticides. Seemingly, the brand effect of pesticides significantly encourages farmers to choose green and low-toxic pesticides. In external support, technical training significantly encourages farmers to choose green and low-toxic pesticides. Furthermore, better infrastructure and local market conditions significantly encourage farmers to reduce the use of conventional pesticides.

Pesticides play an important role in agricultural development. However, pesticide application can result in both acute and chronic human toxicities, and the adverse effects of pesticides on the environment and human health remain a serious problem. There is therefore a need to discuss the application methods for pesticides, the routes of pesticide exposure, and the health risks posed by pesticide application. The health problems related to pesticide application and exposure in developing countries are of particular concern. The purpose of this paper is to provide scientific information for policymakers in order to allow the development of proper pesticide application technics and methods to minimize pesticide exposure and the adverse health effects on both applicators and communities. Studies indicate that there are four main pesticide application methods, including hydraulic spraying, backpack spraying, basal trunk spraying, and aerial spraying. Pesticide application methods are mainly selected by considering the habits of target pests, the characteristics of target sites, and the properties of pesticides. Humans are directly exposed to pesticides in occupational, agricultural, and household activities and are indirectly exposed to pesticides via environmental media, including air, water, soil, and food. Human exposure to pesticides occurs mainly through dermal, oral, and respiratory routes. People who are directly and/or indirectly exposed to pesticides may contract acute toxicity effects and chronic diseases. Although no segment of the general population is completely protected against exposure to pesticides and their potentially serious health effects, a disproportionate burden is shouldered by people in developing countries. Both deterministic and probabilistic human health risk assessments have their advantages and disadvantages and both types of methods should be comprehensively implemented in research on exposure and human health risk assessment. Equipment for appropriate pesticide application is important for application efficiency to minimize the loss of spray solution as well as reduce pesticide residuals in the environment and adverse human health effects due to over-spraying and residues. Policymakers should implement various useful measures, such as integrated pest management (IPM) laws that prohibit the use of pesticides with high risks and the development of a national implementation plan (NIP) to reduce the adverse effects of pesticides on the environment and on human health.

Pesticide is any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest (insects, mites, nematodes, weeds, rats, etc.), including insecticide, herbicide, fungicide etc. used to control pests and to safeguard public health. Use of pesticide has secured the food production and enhanced the amount of produce. Once the pesticide enters in contact with the environment, its fate is determined by several natural processes (adsorption, degradation, erosion and leaching to groundwater). Of the total pesticides applied in agriculture, about 1-10% reach to the target plant, about 30% is lost in atmosphere, nearly 1-5% is lost due to runoff/surface erosion and roughly 1% is lost by leaching. Pesticides applied in the soil leaches up to 50 -100 %. Pesticide management reduces contamination of water from pesticides and foster effective and safe use of pesticides without causing degradation to the environment. This study provides an overview of pesticides on recent developments in sustainable management on strategies, practices and their effectiveness, core elements, principles of Integrated Pest Management (IPM) and bio-pesticides in crop protection. This study recommends that during application of pesticides, guidelines approved by FAO and WHO (2014), from production to disposal of pesticides in the 'International Code of Conduct on Pesticide Management' (4th version) should be strictly followed by government regulators, the private sector, civil society as a best practice in managing pesticides throughout their lifecycle.

Excessive use of organophosphate pesticides is becoming more common these days. This can affect the level of pesticide residues in farmers' crops. Excessive spraying of pesticides can result in environmental pollution both small and large scale. If excessive exposure to these pesticides can cause damage to the ecosystem. The purpose of this study was to determine the level of organophosphate pesticide residues found in horticulture plants. This research method is a systematic review, by analyzing various studies regarding the contamination of organophosphate pesticide residues in horticultural crops. There are 20 studies from within the country. The results obtained in the form of levels of pesticide residues that are still below the threshold of the BMR (Maximum Residue Limit) of pesticides determined by SNI. Two other studies show that no pesticide residue content was detected. Conclusion: This shows that the sample tested is still safe for consumption. Socialization and education about the doses of pesticide use and how to reduce levels of pesticides in horticultural crops are needed to reduce the risk of exposure to pesticides

Runoff characteristics of particulate pesticides from paddy fields have been intensively observed in the Koise River in Japan. The 8 pesticides that are applied to paddy fields were analyzed in both particulate and dissolved forms. The concentrations and the detection frequencies of particulate pesticides were lower than those of dissolved pesticides. The particulate pesticide concentrations in the river water were evaluated based on the soil sorption coefficient, particulate organic carbon concentration, and dissolved pesticide concentrations. The particulate pesticide concentrations in the river were higher than evaluated concentrations because the paddy soil contained more pesticides than did suspended solids in the river water discharged during rain events, and because the desorption rates of pesticides were slow. In observations made during rains, the particulate pesticide concentrations increased with the increases in both the discharge rate and the concentrations of suspended solids. The particulate loading was slight compared with dissolved loading, but particulate pesticides may be influenced by enclosed areas such as a lake or estuary because under such conditions particulate matter settles vertically and the pesticide decomposition rate in sediment is slow compared with that in water.

A field study was conducted to evaluate knowledge, practice and use of pesticides among thirty commercial vegetable growers of Dhading district of Nepal. More than four in five were using pesticides and more than one third were using it for more than six years. Nearly half of them spray pesticides five to six times. More than one-sixth pesticides used were extremely hazardous, which were barred for general agriculture use. Waiting period is less than four days for nearly two-third growers. More than three-forth know the adverse effect of pesticides and nearly half experienced symptoms of health hazards. Majority did not receive any official training on pesticides and nearly one-third doesn't read information available in pesticide label. Nearly half were not using Personal Protective Equipment during pesticide application. Nearly two-third throw pesticide container anywhere after using it. The finding of this study is oriented to the following recommendation: the need for awareness, education and training on the uses of pesticides to the farmers and effective monitoring program for pesticide residues in vegetables.Key words: Awareness; Health effects; IPM; Pesticides; VegetablesThe Journal of AGRICULTURE AND ENVIRONMENTVol. 11, 2010Page: 95-100Uploaded date: 16 September, 2010

When the production or use of a product imposes a cost or benefit on a third party, this is referred to as an externality. Externalities of pesticides are associated with social and environmental costs. However, there is still a lack of a systematic method for evaluating and internalizing the externalities of pesticides. This study utilizes the pesticide’s environmental impact quotient and environmental accounting methods to assess the external costs associated with pesticide usage in the winter-wheat–summer-maize cropping system in China’s northern plains, with a specific focus on the pesticide use in Botou City during the year 2020 as a case study. Additionally, we introduce the concept of the net external value of pesticides and propose a methodology for its internalization, aiming to quantify the external costs induced by pesticide usage and explore the possibility of integrating them into market transactions. The results showed that the total external costs of pesticide use are 423.9 USD ha−1, with a positive external value of 171.9 USD ha−1 and a net external value of −252.0 USD ha−1. The negative external costs associated with pesticide use outweigh the positive external values. External costs varied significantly according to environmental receptors, after retaining two significant figures: applicators accounted for 45% of the total external costs, followed by pickers (32%), consumers (11%), groundwater (4.5%), fish (3.9%), beneficial insects (1.7%), birds (1.3%), and bees (1.1%). The external costs of maize cultivation were 33% higher than those of wheat cultivation. The application of herbicides resulted in the highest external costs compared with fungicides and insecticides. Based on the internalization of the results, imposing an ecological tax on pesticide users is recommended, with rates of 3.29% for wheat and 6.76% for maize. This research contributes to sustainable agricultural development by providing valuable insights for farmers in selecting environmentally friendly pesticides and informing the implementation of ecological taxes on pesticide usage.

Pesticides are a large and heterogenous group of chemicals with a complex geographic distribution in the environment. The purpose of this study was to explore the geographic distribution of pesticides in Danish drinking water and identify potential patterns in the grouping of pesticides. Our data included 899,169 analyses of 167 pesticides and metabolites, of which 55 were identified above the detection limit. Pesticide patterns were defined by (1) pesticide groups based on chemical structure and pesticide–metabolite relations and (2) an exploratory factor analysis identifying underlying patterns of related pesticides within waterworks. The geographic distribution was evaluated by mapping the pesticide categories for groups and factor components, namely those detected, quantified, above quality standards, and not analysed. We identified five and seven factor components for the periods 2002–2011 and 2012–2018, respectively. In total, 16 pesticide groups were identified, of which six were representative in space and time with regards to the number of waterworks and analyses, namely benzothiazinone, benzonitriles, organophosphates, phenoxy herbicides, triazines, and triazinones. Pesticide mapping identified areas where multiple pesticides were detected, indicating areas with a higher pesticide burden. The results contribute to a better understanding of the pesticide pattern in Danish drinking water and may contribute to exposure assessments for future epidemiological studies.

Introduction: Previous studies found that young children, children, pregnant women, and farmers are at risk of pesticide exposure. Organophosphate pesticides are detected in children’s urine, but other types of pesticides, their toxicity classification, and their toxicity level have not been identified. Hence, this study aims to identify types and toxicity levels of pesticides that are possible causes of health problems in an agricultural area. Methods: The population of the study were 1,017 households in two villages of an agricultural area of Brebes Regency, Indonesia. The data were collected from 166 participants using a cross-sectional design involving questionnaires to identify the characteristics of the respondents and observations to identify the pesticide, pesticide packaging, and pesticide residue in their houses. The toxicity levels of the pesticides were identified based on the pesticide toxicity classification recommended by the World Health Organization (WHO). Potential health problems due to pesticides were subsequently identified based on literature reviews. Results and Discussion: According to the results, organophosphate, carbamate, and pyrethroid pesticides were found in 30.7% of the respondents’ houses. The toxicity levels of the pesticides ranged from highly hazardous (Ib) to unlikely presenting acute hazard (U). The potential health problems due to pesticides varied from poisoning symptoms to genetic disorders and polymorphisms. Conclusion: There were three types of pesticides with toxicity levels ranging from highly hazardous to unlikely presenting acute hazard in the agricultural area in Brebes Regency

Pesticide helps to enhance agricultural production, however, it significantly affect both socio and environmental entities of a country. In Nigeria, pesticide is widely used, thus its traces have been detected in water, soil and air. Several studies have already indicated that most of the environmental ecology (air, water, and soil) in Nigeria has been contaminated by persistent organic pesticides like organochlorine and organophosphate. Other reasons of high pesticide residues present in Nigeria environment is due to inappropriate dosage applied of pesticides that leaves behind excess. However, its residues are found above safety levels in the air, water, and soil across the nation. Based on previous analysis, it is indicated that 125,000-130,000 metric ton pesticides are being applied annually in Nigeria. Despite banned of some pesticides such as dichlorodiphenyltrichloroethane- and -Hexachlorocyclohexane, they are still being used by farmers in their agricultural production. Many of the Class 1 (high extremely toxic) pesticides are still being used in developing countries like Nigeria. Hence, there is need to sensitize and educate the general public especially the end-users (farmers) particularly on management practices of pesticides. Considering these entire hazardous situations, in this article the history of pesticide used in Nigeria has been reviewed in detail. The article also discussed the effects of pesticide use in Nigerian waters, soil and on crops. The risk of residual pesticide on agricultural workers, pesticide residue risk preventive measures by the Federal Government of Nigeria, banned and restricted pesticides in Nigeria, Nigerian Government and its efforts to eliminate persistent organic pesticides in use are also reviewed in details.

Introduction: The use of pesticides not only has benefits for product growth but also causes problems with the entry of pesticide residues in the food chain to pollution to the environment. This study aims to formulate ways to reduce pesticide contamination in the environment and agricultural products. Discussion: This literature review was conducted using the PRISMA method using 35 articles 14 of which were published in the ScienceDirect database, 12 in the Proquest database, and 9 in the Pubmed database. Environmental pollution due to pesticides is caused by the behavior of spraying pesticides and disposing of used pesticides by farmers. Ways to reduce it are by measuring how much pesticide is needed, training to increase knowledge about agricultural practices in preparing the required dose, and regularly monitoring environmental quality. Pesticide residues can increase due to the application of pesticides at harvest, and they can be reduced by washing, peeling, and cooking processes. In addition, another proven effective way to reduce pesticide residues is using an electrolyzed water treatment, sonolytic ozonation, and ozonated water. Conclusion: The use of unsafe pesticides will harm the environment and endanger health through the food chain. Training for farmers to use pesticides properly is considered effective in reducing pesticide pollution in the environment. In addition, the reduction of pesticides in agricultural products can be done by washing, peeling, cooking (boil, boil and fry), electrolyzed water treatment, sonolytic ozonation, and ozonated water.

The study Evaluated the Impact of Effective Management Practices in Mitigating the Toxicity Symptoms of Pesticides Preparation, Storage and Application in Kebbi State, Nigeria. Structured Questionnaires were used to obtained information from the respondents. Descriptive statistics comprising frequency distribution tables and percentages and were used for Data Analysis. Likert scale was used to determine farmer’s perception on the toxicity symptoms of pesticides of pesticides preparation, storage and application employed by farmers when handling pesticides. The result of the study showed that majority of the respondents (90%) were male while female formed the minority in pesticide usage with only (10%). The study also showed that all the respondents (100%) were married and engaged in agricultural activities. The study further revealed that all the respondents never had any formal training on the use of pesticide from either governmental or non -governmental organizations. The research study also found out that all (100%) of the respondents were not aware of the toxicity of pesticides during preparation, storage and application. Likert Scale Analysis showed a negative perception by farmers on awareness of pesticide toxicity during preparation, storage and application. On perception of the respondents on the toxicity of pesticides during preparation, storage and application, the study revealed that Nausea, Dizziness, Diarrhea, Respiratory Difficulty, Skin Irritation, Rashes, Fever, Peeling of the Skin, Vomiting, and Headache were the serious toxicity effects of pesticide. It is concluded that respondents had negative perception on pesticide management of toxicity of pesticides during preparation, storage and application. It is therefore recommended that appropriate authorities should enforce the use of protective clothing, appropriate equipment and correct handling practices when using pesticides. Existing pesticide regulations and monitoring policies should be enforced. Government should also intensify efforts at registering and controlling distribution of pesticides and banning hazardous ones. It should also enforce the making of less toxic pesticides available to farmers.

Fruits have nutritional value, but they can also be sources of toxic contaminants, such as pesticide residues. Pesticides used for fruit production results in increased health risks and health costs, humiliation of the environment and productivity loss. This research aimed to conduct to estimate presence of pesticide residues in summer season fruit purchase from local market. Pesticides were precisely detected in fruit samples collected from the market and the technique (GC-ECD) was used for analyzing and studying organochlorine pesticides in three fruits of the summer season, i.e., (plum, kiwi fruit and pineapple). The maximum residual limits (MRLs) values were compared with pesticide concentrations. In fruit sample, mean values of pesticide concentration residues were found. All fruits were found to be contaminated with pesticides. The concentrations of monitoring pesticides were less than the (MRL) values. However, the severe health problems may be created by the regular eating of pesticide infected fruits. It can be concluded that the periodical monitoring of fruits for pesticide residues is essential to evaluating their contamination grade and producing awareness on the health hazards involved in pesticide misuse.

Majority of the farmers are unaware of pesticide types, level of poisoning, safety precautions and potential hazards on health and environment. According to the latest estimate, the annual import of pesticides in Nepal is about 211t a.i. with 29.19% insecticides, 61.38% fungicides, 7.43% herbicides and 2% others. The gross sale value accounts US $ 3.05 million per year. Average pesticides use in Nepal is 142 g a.i./ha, which is very low as compared to other Asian counties. The focus of this paper is to analyze the use and application status of pesticides in Nepal to aware the society about adverse effects of chemical pesticides in the environment . Pesticidal misuse is being a serious concern mainly in the commercial pocket areas of agricultural production, where farmers are suffering from environmental pollution. Incidence of poisoning is also increasing because of intentional, incidental and occupational exposure. Toxic and environmentally persistent chemicals are being used as pesticides. Many studies showed that the chemical pollution of the environment has long-term effects on human life. It is therefore essential that manufacture, use, storage, transport and disposal of chemical pesticides be strictly regulated.

The use of various types of active ingredients with high intensity pesticides in dealing with pest disturbances often makes farmers pay less attention to the negative impacts. Deltamethrin, sipermetrin, λ-cyhalothrin and chlorpyrifos are active ingredients of pesticides that are often used by cocoa farmers to control pests Helopeltis sp. spp. which is one of the main pests in cocoa plants. Field tests on pesticide application were carried out on cocoa plants with Helopeltis sp. spp. High. This test was carried out on 4 treatment blocks applied with different active ingredients. Pesticide residue testing was carried out on cocoa beans, before and after pesticide application using the QuEChERS method on GC-ECD. The results of pesticide residue testing showed that the use of λ-cyhalothrin pesticides did not leave pesticide residues, while sipermetrin pesticides left far fewer pesticide residues compared to deltamethrin and chlorpyrifos pesticides. The results of these pesticide residues are compared to the Pesticide Maximum Residual Limit (MRL) according to the European Commission Part A of Annex I to Reg. 396/2005, shows the results of λ-cyhalothrin and cipermethrin pesticide residues test under pesticide MRL, while the results of deltamethrin and chlorpyrifos pesticide residue test are above the specified pesticide MRL.

Abstract Pesticide use and worker exposures to pesticides in the US cannabis industry have not been studied due to cannabis being illegal at the federal level. Without knowing the types of pesticides being used in this industry, it is difficult to assess whether workers are being exposed to potentially dangerous pesticides. When recreational cannabis became legal in the state of Oregon in 2014, the Oregon Department of Agriculture (ODA) published a list of recommended pesticides for use in the cannabis industry and developed the state's pesticide testing regulations for all cannabis products, medicinal and recreational. Using the state's pesticide testing data, the aim of this study was to investigate the types of pesticides being used in the Oregon cannabis industry and if they present a hazard to cannabis workers. Both recreational and medicinal cannabis samples contained high levels of residual pesticides and pesticides not legally allowed to be used on cannabis products. Medicinal cannabis products were found to have mean levels of residual pesticides that were 3–12 times higher than recreational products. Nine of the 50 pesticides identified were classified highly or extremely hazardous by the World Health Organization.

Pesticides pose a potential threat to bee health, especially in combination with other stressors, such as parasites. However, pesticide risk assessment tests pesticides in isolation from other stresses, i.e., on otherwise healthy bees. Through molecular analysis, the specific impacts of a pesticide or its interaction with another stressor can be elucidated. Molecular mass profiling by MALDI BeeTyping® was used on bee haemolymph to explore the signature of pesticidal and parasitic stressor impacts. This approach was complemented by bottom-up proteomics to investigate the modulation of the haemoproteome. We tested acute oral doses of three pesticides—glyphosate, Amistar and sulfoxaflor—on the bumblebee Bombus terrestris, alongside the gut parasite Crithidia bombi. We found no impact of any pesticide on parasite intensity and no impact of sulfoxaflor or glyphosate on survival or weight change. Amistar caused weight loss and 19–41% mortality. Haemoproteome analysis showed various protein dysregulations. The major pathways dysregulated were those involved in insect defences and immune responses, with Amistar having the strongest impact on these dysregulated pathways. Our results show that even when no response can be seen at a whole organism level, MALDI BeeTyping® can detect effects. Mass spectrometry analysis of bee haemolymph provides a pertinent tool to evaluate stressor impacts on bee health, even at the level of individuals.

Under the National Agri-Environmental Health Analysis and Reporting Program (NAHARP), pesticide fate models are being used to develop an indicator of risk of water contamination by pesticides (IROWC-Pest) in Canada. The large number of model runs needed for a national analysis of the risk of pesticide leaching to ground water required the development of a computer program, AutoPFM (Automate Pesticide Fate Model), to automate the running of pesticide fate models. Using Manitoba as a test province, and the selected pesticide fate models PRZM, LEACHP, and MACRO, AutoPFM permitted the estimation of the leaching potential of the fourteen most used agricultural pesticides in Manitoba. Assuming an application rate of 300 g ha-1 for each pesticide, only six pesticides demonstrated leaching across most soil series. For these six pesticides, there was significant correlation in how PRZM and LEACHP ranked the leaching potential of 337 Manitoba soil series. Because of its long running times, the estimation of leaching potential with MACRO was limited to two pesticides (2,4-D and MCPA). For these pesticides, MACRO showed significant correlation with the PRZM and LEACHP in ranking the soil series. Based on the results described in this paper, PRZM was chosen as the pesticide leaching model for use in IROWC-Pest.

Pesticides are chemicals used in agriculture to prevent and eradicate plant pests that have the potential to interfere with agricultural output. Excessive use of pesticides without regard to applicable safety standards will have the opportunity to be directly exposed to dangerous pesticide active ingredients. This behavior can have a negative impact on health, one of which is pesticide poisoning. Most of the vegetable farmers in Garuda Sakti do not understand the dangers of pesticides, so education is needed about the impact of pesticides on health and the environment. This effort is made to increase farmers' understanding of the proper use of pesticides so as to prevent the adverse effects of pesticides.

Groundwater pollution with pesticides has affected every country on every continent. An important challenge for researchers and regulatorу bodies in all countries is to develop methods and tools for predicting the risks to groundwater that are associated with pesticide use. In this paper, the generally accepted methods for studying pesticides migration are reviewed and analyzed from the point of view of their applicability for assessing the risk of pesticides impact on groundwater. Using examples, it is shown that the available methods may be divided into two categories, direct and indirect ones. The indirect methods (mobility indices and field studies of pesticide migration) make it possible to compare the migration ability of a pesticide molecule and to determine the depth of penetration of the pesticide into the soil. The direct methods (modeling, lysimetric studies, and monitoring) provide for the determination of pesticide concentrations in groundwater or groundwater leachate, which makes such methods useful in assessing the risk of pesticide use. Thus, by comparing the measured pesticide concentrations in water with acceptable threshold values, it is possible to determine the risk level of a pesticide. Examples of calculating the mobility indices indicate that their estimates differ from each other. Disadvantages of migration field experiments are related to analytical problems and to the short duration of a study. Modeling the migration of pesticides is an effective tool that makes it possible to quickly determine pesticides concentration of in water runoff and to identify the pesticides that can pollute groundwater under specific soil and climatic conditions. Calculations show that for 40 pesticides out of 180 licensed for use in the Russian Federation, their predicted concentrations exceed 1 µg/l. The second method that allows to directly determine concentrations in leachate is lysimetric experiments. A long-term study of the migration of 4 pesticides showed that all toxicants migrate beyond the soil profile. A third useful tool is pesticides monitoring in groundwater. Further development and dissemination of this method for controlling pesticides in groundwater is an important task for the regulatory authorities and the scientific community of the Russian Federation in the near future.

Biopesticides are perceived as a feasible alternative to chemical pesticides, providing an effective approach to pest management while mitigating the undesirable effects of chemical pesticide overuse. Yet, due to the distinctive attributes of the two types of pesticides, farmers often adopt a combination of both. This study aimed to probe the interdependent relationship underlying the mixed use of chemical pesticides and biopesticides by farmers in the rice–crayfish integrated system (RCIS) in Hubei province, China. We also sought to identify influencing factors and associated consequences of this practice. Given that the adoption of chemical pesticides and biopesticides by farmers is not mutually exclusive, a multivariable probit model was utilized to estimate simultaneous pesticide applications. Survey data from 736 RCIS farmers revealed that 10.50% of the sample farmers employ a combination of chemical pesticides and biopesticides. A substitution relationship was observed between the adoption of chemical pesticides and biopesticides by farmers, whereas no significant complementary relationship was found in the application of the two types of pesticides. The primary motivation for the mixed use of pesticides by farmers is to achieve superior pest control efficacy. Notably, when integrating the use of pesticides, farmers pay less attention to factors such as resource endowments and multiple production objectives. Further analysis indicated that farmers display significant concern for pesticide attributes including insecticidal efficacy, toxicity, insecticidal spectrum, and validity period. The mixed use of pesticides has resulted in a decreased frequency of pesticide application but has escalated the cost. While the mixed use of pesticides elevated the selling price of rice, no significant improvement was observed in yield and output value. The insights garnered from this study offer strategic implications for policymakers on how to enhance the judicious adoption of pesticides by farmers.

On the African continent, ongoing agriculture intensification is accompanied by the increasing use of pesticides, associated with environmental and public health concerns. Using a systematic literature review, we aimed to map current geographical research hotspots and gaps around environmental and public health risks research of agriculture pesticides in Sub-Saharan Africa (SSA). Studies were included that collected primary data on past and current-used agricultural pesticides and assessed their environmental occurrence, related knowledge, attitude and practice, human exposure, and environmental or public health risks between 2006 and 2021. We identified 391 articles covering 469 study sites in 37 countries in SSA. Five geographical research hotspots were identified: two in South Africa, two in East Africa, and one in West Africa. Despite its ban for agricultural use, organochlorine was the most studied pesticide group (60%; 86% of studies included DDT). Current-used pesticides in agriculture were studied in 54% of the study sites (including insecticides (92%), herbicides (44%), and fungicides (35%)). Environmental samples were collected in 67% of the studies (e.g., water, aquatic species, sediment, agricultural produce, and air). In 38% of the studies, human subjects were investigated. Only few studies had a longitudinal design or assessed pesticide’s environmental risks; human biomarkers; dose-response in human subjects, including children and women; and interventions to reduce pesticide exposure. We established a research database that can help stakeholders to address research gaps, foster research collaboration between environmental and health dimensions, and work towards sustainable and safe agriculture systems in SSA.

The reaction of pesticides with the OH radical, is the most dominant annihilation reaction ofthe atmosphere. Phosmet, Azamethiphos, Coumaphos and Temephos were used as organophosphorouspesticides, and Methiocarb, Carbofuran and Pirimicarb compounds were used as carbamate pesticideswith the aim of investigating the kinetics of the reactions of Organophosphorous (OPs) and Carbamate(CBs) Pesticides with the OH radicals. In aqueous TiO2 suspensions, the degradation reactions viaphotocatalytic-effect of the seven pesticides selected as pollutants were analysed, and the impact of theinitial concentration was calculated. All experiments were conducted in the same photoreactor and underthe same conditions as three repetitions. The optimum amount of photocatalyst for the studied pesticidewas determined and TiO2 concentration for all experiments were taken as 0.2 g/100 mL. Considering thatorganic pollutants are present in water in trace amount, the initial concentrations for all organiccompounds were added so as to be1.0x10-4 molxL-1, into the suspensions and the solution containing theorganic pollutant. In this study, degradation speed of pesticides were determined experimentally, and thefastest degrading pesticide was tried to be found out.

Pesticides are beneficial in protecting crops from pests and improving agricultural productivity; however, concerns on pesticide pollution in water have increased due to their indiscriminate use and lack of adequate regulations. Many studies have focused on the risks of pesticides considering the limited number and types of pesticide residues in crops and soils, and duration, and very few have focused on surface water throughout the year. Therefore, this study comprehensively identified 308 pesticides in surface water samples collected monthly over one year in the Saemangeum Basin, Korea. Both targeted and non-targeted analyses were used to identify 171 and 24 pesticides, respectively. Results highlight the extensive extent of pesticide contamination. Among the quantified pesticides, bromobutide and pretilachlor consistently exhibited high concentrations and risk levels, as indicated by their elevated risk quotient (RQ) values. Seasonal variations in pesticide concentrations revealed distinct patterns with intensified herbicide use during summer and increased insecticide concentrations during autumn. This study highlights the presence, distribution, and associated ecological risks of pesticides in surface waters, emphasizing the necessity of comprehensive monitoring and regulatory measures to protect aquatic ecosystems. The high RQ values identified for specific pesticides underscore the urgent need to implement effective strategies to mitigate these environmental risks.

Hematological parameters and changes in stress-induced functionalities of cellular enzymes have been recognized as valuable tools for monitoring fish health and determining the toxic effects of pesticides. The present study was conducted to evaluate the toxic effect of selected pesticides viz., Ekalux (EC-25%), Impala (EC-55%), and Neemstar (EC-15%) on freshwater catfish Mystus keletius. Fish were exposed to sub-lethal concentrations (mg/L) of the selected pesticide for a period of 7, 14, 21, and 28 days. Hematological parameters viz., total erythrocyte (RBC), hemoglobin (Hb), and hematocrit (Ht) packed cell volume values decreased with an increase in exposure time to pesticides, whereas the values for parameters viz., leucocytes (WBC), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH) increased significantly. A decrease in packed cell volume (PCV) and hemoglobin values coupled with decreased and deformed erythrocytes as signs of anemia were also observed. The effect of pesticides on RBC content was 1.43 (million/mm3) on day 7 and reduced to 1.18 (million/mm3) on days 14 and 21. A similar trend was found for Impala on RBC, which had an initial value of 1.36 (million/mm3) on day 7 and reached a value of 1.10 (million/mm3) on day 28. In contrast, the value of Neemstar decreased from 1.59 (million/mm3) on day 7 in control to 1.02 (million/mm3) on day 28. Data indicates that the order of toxic effect of pesticides recorded a maximum for Impala followed by Ekalux and Neemstar in the selected fish model. Likewise, the overall pattern of pesticidal activity on cellular enzymes (GDH, MDH, and SDH) recorded a maximum toxic effect for Impala followed by Ekalux and Neemstar. Results indicate that Chlorpyrifos pesticide-Impala evoked maximum toxic effect on selected tissues compared to the other two pesticides tested. Statistical analysis of the summative data using two way ANOVA was statistically significant (p-value < 0.001). The differences in the hematological parameters analyzed are attributed to the physiological acclimatization of the fish to the local conditions, which influences the energy metabolism and consequently determines the health status of the fish. Overall, Impala exhibited the highest pesticidal activity on cellular enzyme, followed by Ekalux and Neemstar. Results suggest that natural pesticides may be preferable for rice field application in terms of environmental safety.

The regular usage of pesticides in agricultural fields results in the development of a pesticide-resistant microbial population. Vegetable cultivation is a common practice in the agricultural growing areas of Manjoor, Kerala. The present study was envisaged to understand the resistance of microorganisms to different types and doses of pesticides. The study revealed that heterotrophic bacteria are capable of resisting lower concentrations (0.01 and 0.001%) of the pesticides lindane and methyl parathion while a higher concentration of carbaryl (0.1%) could also be tolerated. In the soil sample where there was no prior addition of pesticides, the heterotrophic bacteria could only tolerate very low concentrations of pesticides The results of mean pesticide-resistant bacterial load when compared to normal Total Heterotrophic Bacteria (THB) of soils indicate that pesticides exhibited an inhibitory effect on the heterotrophic bacteria of soils collected from different agricultural fields and the pesticide-resistant bacterial load was lower than normal THB.

The use of pesticides is often given under extreme conditions. The excess use of these pesticides can harm both the farmers directly and the affected environment; this is the impact of the uncontrolled use of pesticides. There is a need for a control system to control the distribution of pesticides on agricultural land. This article seeks to provide a control system design for controlling the distribution of pesticides by utilizing photometric technology integrated with the internet of things (IoT). The control system is designed automatically with a sensing system or an operating record. It is expected to be able to disseminate the correct use of pesticides to achieve production efficiency. This study provides a design of an automatic control system for pesticide distribution IoT-based. We use a photometric sensor to control the pesticide distribution. Future work can be implemented for prototype work due to smart farming to control pesticide distribution automatically.

AbstractNewly available data from USDA's Pesticide Data Program allow us to trace pesticide residues on fruits and vegetables to their sources among various uses. We show that pesticide residues come from four sources: on-farm pesticide use; post-harvest pesticide use; pesticide use on imported food; and canceled pesticides that persist in the environment. Post-harvest pesticides account for the largest share of residue detections. Farmers' pest control choices influence consumers' dietary intake of pesticides, but the way in which food is marketed and the history of pest management techniques used on farms may have a greater influence. For pesticides that U.S. farmers currently use, the data show the geographic sources of residues and the extent to which use contributes to dietary intake risks. This information could be used to target development of pest control alternatives more narrowly. However, research to develop on-farm pest control alternatives will not address all pesticide residue risks in consumers' diets.

AbstractIn recent years, pesticides have captured the attention of both policymakers and the general public. A particular focus has been the transparency of the EU-level procedure for approving active substances, spurred by controversies surrounding the active substance glyphosate. Active substances are the ingredient in pesticides with the pesticidal effect. Once an active substance is approved at EU level, the pesticide containing that active substance must be authorised by each Member State. For this purpose, the EU's 2009 Plant Protection Product Regulation divides Member States into three zones—Northern, Central, and Southern—within which, zonal rapporteur Member States evaluate applications for authorisation. National authorisation decisions are based on these zonal evaluations. This novel system governing pesticides is under-researched. Furthermore, unlike active substance approval, the transparency of pesticide authorisation escapes public and policy scrutiny. Drawing on empirical research conducted for the European Parliament, this article evaluates the transparency of the zonal pesticide authorisation procedure. It thus contributes to the literature on transparency a detailed exploration of transparency in a highly complex, decentred, and polycentric risk regulation regime. While it finds that the zonal pesticide authorisation procedure, generally speaking, does not operate transparently, it argues further that levels of transparency within the regime as a whole may vary significantly depending on multiple different factors. It introduces the concept of ‘chiaroscuro regulation’ to characterise and understand these varying levels of transparency across different elements of the regime and considers some of its implications.

<p><em>The use of pesticides in rice production has an impact on the environment. Pesticides are chemicals used to kill or control pests. The use of pesticides carries some risks, but farmers are used to using pesticides. However, the use of pesticides may lead to the contamination of groundwater. Therefore, the research question in this study was whether there any differences in rice production before and after pesticide reduction in Indonesia. This study aimed to analyze the difference between rice production before and after pesticide reduction in Indonesia. The secondary data in this study were rice production data from FAO. Data from 1968 to 1992 were data about rice production before reducing pesticide use in Indonesia, while data from 1993 to 2017 were data about rice production after reducing pesticide use in Indonesia. The applied data analysis was paired sample t-test using SPSS 25. The results indicated that there is a significant difference between rice production before and after reducing pesticide use in Indonesia. </em></p>

Agricultural activities cannot be separated from the use of pesticides to control plant-disturbing organisms. The mercury (Hg) content in pesticides cannot be naturally degraded on agricultural land, so it will be carried off by run-off into the waters. Pesticide’s run-off from agricultural activity along the Sumur Beremas River has an effect in increasing mercury concentrations in the river. This study aims to analyze the effect of pesticide use on mercury concentrations in the Sumur Beremas River and to analyze the capacity of river pollution loads. The effect of pesticide on mercury concentrations was analyzed using Pearson correlation. The capacity of Sumur Beremas River's pollution loads against mercury was analyzed using mass balance method. The results showed that the use of pesticides had a significant effect on the increase in mercury concentrations in river water. The greatest correlation value occurs in downstream of irrigation, namely 0.977, which indicates the high run-off that occurs from agricultural area to the irrigation flow. The concentration of mercury based on the analysis of river pollution loads is 0.00242 ppm, exceeding the standard PP no. 82 of 2001 Class II, 0.002 ppm, which indicates that Sumur Beremas River is no longer able to accommodate the load of mercury pollution.
