Abstract:
Abstract The use of chemical means of protecting plants from diseases and pests to increase yields and improve the presentation of the product leads to negative consequences. The main one is the accumulation of chemical residues in products and the release of resistant forms of pathogens. The use of microbial antagonists that suppress the development of phytopathogenic fungi is considered as an alternative method of plant protection. Biological preparations for suppressing plant diseases are based on antagonist microorganisms, hyperparasites, and biota metabolites. An increase in the share of biological protection and a decrease in the share of the use of agrochemicals in the plant protection system contributes to the improvement of the socio-ecological situation. The search for technological methods for reducing the frequency of treatments is especially important for the cabbage culture. In this regard, this article evaluates the effectiveness of biological products in protecting cabbage agrocenosis and increasing productivity.

Abstract:
Abstract Basic Substances are a newly effective category of Plant Protection Product under EC Regulation No 1107/2009. The first approved application of Equisetum arvense L. opened Part C of Implementing Regulation (EU) No 540/2011, which lists the basic substance approved. Although E. arvense was described as a fungicide extract, subsequent applications like chitosan were related to non-biocide molecules. Consequently, plant protection product data were collected from research on alternative or traditional crop protection methods. They are notably issued or derived from foodstuffs (plants, plant by-products, plant derived products, substances and derived substances from animal origin). Applications are currently submitted by our Institute, under evaluation at different stages of the approval process or already approved. Remarkably, this Basic Substance category under pesticide EU Regulation was surprisingly designed for these non-biocidal plant protection products. In fact, components described as the “active substance” of most of the actual applications are food products like sugars and lecithin. Basic Substance applications for these foodstuffs are therefore a straightforward way of easily gaining approval for them. Here we describe the approval context and detail the agricultural uses of theses food products as Biological Control Agents (BCAs) or biorationals for crop protection. From all deposited or approved Basic Substance Application (BSA), a proof has been provided that non-biocide and food products via physical barrier or lure effects may be effective plant protection products with an acceptable low profile of concern for public and agricultural safety.

Abstract:
Plant protection products stand out from other means of production for agriculture with little price dynamics. The article presents the occurrence and the size of seasonal fluctuations in plant protection product prices in selected EU countries. Due to the availability of data, the prices of plant protection products in Poland, France, Ireland and Greece were analyzed. Seasonal variation analysis was performed using the seasonal decomposition method. The study does not point to a clear seasonality in the prices of plant protection products on the markets analyzed. The seasonality of plant protection products prices was observed only on the Polish and French markets, while the variations in seasonal fluctuations were small. Seasonal price increases were observed for the Polish market from March to June, during the period of increased demand for plant protection products. In the second half of the year, prices generally declined. Seasonal price changes on the French market were similar.

Abstract:
Okara is a soybean transformation agri-food by-product, the massive production of which currently poses severe disposal issues. However, its composition is rich in seed storage proteins, which, once extracted, can represent an interesting source of bioactive peptides. Antimicrobial and antifungal proteins and peptides have been described in plant seeds; thus, okara is a valuable source of compounds, exploitable for integrated pest management. The aim of this work is to describe a rapid and economic procedure to isolate proteins from okara, and to produce an enzymatic proteolyzed product, active against fungal plant pathogens. The procedure allowed the isolation and recovery of about 30% of okara total proteins. Several proteolytic enzymes were screened to identify the proper procedure to produce antifungal compounds. Antifungal activity of the protein digested for 24 h with pancreatin against Fusarium and R. solani mycelial growth and Pseudomonas spp was assessed. A dose-response inhibitory activity was established against fungi belonging to the Fusarium genus. The exploitation of okara to produce antifungal bioactive peptides has the potential to turn this by-product into a paradigmatic example of circular economy, since a field-derived food waste is transformed into a source of valuable compounds to be used in field crops protection.

Abstract:
Control of pathogens by means of plant-derived plant protection products (PPPs) can be an effective, sustainable and environmentally friendly method of crop protection in organic agriculture. Larix decidua (European larch) bark is a by-product of the wood processing industry and provides a readily available, low cost and sustainable raw material. It was therefore planned to commercialise Larix extracts, containing two highly active diterpenoids (larixyl acetate and larixol) into a marketable PPP, Larixyne®, to combat grapevine downy mildew (Plasmopara viticola) in organic farming. This thesis outlines the processes and knowledge developed in order to facilitate the commercialisation of Larixyne®: (i) Analytical protocols using high-performance liquid chromatography (HPLC) and gas chromatography (GC-FID) techniques to quantify larixyl acetate, larixol and epimanool (the primary impurity) in Larix extracts were developed. (ii) Methods for large scale extraction and purification of active compounds from Larix were optimised in line with EU specifications for products with organic agricultural use. Through extraction with 2-amino-2-methyl-1-propanol (AMP), Larix bark contained extract compositions of up to 30.53% larixyl acetate and 8.45% larixol. Larixyl acetate and larixol extracts were isolated in sufficient quantity (8.0 kg) for large scale field trials. (iii) High-yield sources of larixyl acetate and larixol were evaluated and identified through screening a range of plant samples from central and northern Europe. Larix samples were found to vary in content of larixyl acetate (median 0.017% w/w, range 0.000 – 4.544% w/w), larixol (median 0.003% w/w, range 0.000 – 0.578% w/w), and epimanool (median 0.009% w/w, range 0.000 –0.752% w/w). (iv) The activity of larixyl acetate, larixol, epimanool and formulated products of Larix extracts against P. viticola on Vitis vinifera were demonstrated. Larixyl acetate and larixol exhibited excellent activity in vitro (mean MIC100 of 7 and 16 μg/mL) and in planta (EC50 0.2 – 0.7 mg/mL).

Abstract:
Risk assessment process is complex because it requires a multidisciplinary approach. In official European procedures, risk is assessed on standardised scenarios, where the territory, at different scale levels is described without taking into account the spatial variability of parameters. These approaches represent a powerful tool to characterize potential risk, anyway results obtained are not representative of actual site-specific conditions. The aim of this research was to analyse the main critical issues of agrochemicals risk assessment in terrestrial ecosystems. Different steps of agrochemicals risk assessment were considered and evaluated coupling field studies with predictive approaches. Different scale levels of risk assessment, with particular attention on exposure evaluation, were considered. Risk for pollinators was selected as a specific case of study and a procedure to assess exposure and risk for these organisms was developed.

Abstract:
The level of alteration in response to the same level of exposure can vary greatly among different ecosystems: in particular, effects provoked by chemicals are not only relying on their “absolute toxicity” and on their concentration, but also on the ecological vulnerability of the system. Vulnerability is often overlooked in current risk assessment procedure, but its knowledge is pivotal in site-specific studies, where the object of the protection is shifted from a generic scenario to a real ecological system. The study of ecological vulnerability confirms that risk assessment, as becoming site-specific, needs more ecological knowledge. In this path, the use of ecological and biological traits of organisms has proven to be a promising approach to evaluate the ecological vulnerability at different level of biological organization. In this work the issue of the ecological vulnerability has been considered from several different perspectives, using multiples methodologies and working at completely different scales. The leading thread is to show how an ecologically based approach can enhance our understanding of environmental processes and thus improving risk assessment methodologies.

Full text
Abstract:
The use of crop protection products (CPPs) is essential to improve crop production levels and feed the rising global population. Safety testing of CPPs is also essential to ensure that their use does not adversely affect human health or the environment. Currently, laboratory-based studies typically over-estimate the environmental persistence of CPPs in the environment. The inclusion of environmental variables that are currently omitted from laboratory studies, such as non-UV light, could reduce the disparity between laboratory and field degradation studies. The inclusion of light resulted in a significant reduction in extractable parent compound for benzovindiflupyr, chlorotoluron, prometryn, imidacloprid, and fludioxonil compared to dark conditions. In contrast, a significantly slower rate of cinosulfuron transformation was observed under light compared to dark conditions. In a separate experiment, terminal restriction fragment length polymorphism showed that under light conditions, the soil surface (0-3 mm) harboured distinct phototroph, bacterial and fungal communities compared to the underlying bulk soil (3-12 mm), or dark incubated soil. 454 pyrosequencing revealed that light selected for diazotrophs at the soil surface, including Nostoc punctiforme, in addition to heterotrophic bacteria, particularly within the phylum Firmicutes. Metatranscriptomic analysis showed that light also selected for actively transcribing photosynthetic eukaryotes at the soil surface, such as Chlorophyceae and Saccharomycetes, in addition to heterotrophs, such as Nostocaceae. Finally, light selected for major soil functions such as photosynthesis, and reduced the alpha and beta diversity of predicted protein coding regions at the soil surface. This work has important implications for CPP regulatory studies and soil surface management practices.

Farah, Abdiqani Ahmed. "The development of a commercially-available Neem seed kernel extract as a soil-applied systemic granular plant protection product." Thesis, University of Glasgow, 2010. http://theses.gla.ac.uk/1849/.

Full text
Abstract:
Crude extracts of the seed kernels of the neem tree (Azadirachta indica) are widely used as plant protection products. The active ingredient (a.i.) of these extracts is azadirachtin A (aza A). aza A is a phytochemical (botanical) complex secondary metabolite which, with it is multiple toxic effects on insects, protects the plant against predation. Aza A is present in only low concentration in neem oil, but makes up 20-50% in the NSKEs extracted by polar solvents from the kernels. However, when used as foliar sprays it is rapidly destroyed by sunlight, and might be more effective if it is used systemically. Therefore the aim of the project was to extend previous work and to prepare a pelleted version of the main commercially-available neem-seed kernel extract, NeemAzal®-Technical (NAT) produced by Trifolio GmbH, in preparation for the expected registration of the product in the UK in 2011. It was first necessary to purify a quantity of aza A for quantification of the a.i. pelleted material and in soil and plants in the rest of the project. In achieving high purity (over 98%) aza A, reverse phase chromatographic methods were used, and mass spectrometery was used to confirm purity and identification. A final quantity of 6.2 mg of azadirachtin A was obtained from 4 gm of NAT, a yield of 0.15%. If aza A and the other neem terpenoids are to be used to plant protection, they must have a low phytotoxicity. Effect of NAT on the germination and its ensuing seedling development of two commercially important crops, sugar beet and cabbage was examined. NAT did have an inhibitory effect on seedling growth at 10-3 M aza A. In order to explore the inhibitory affect of aza A, the second part of the chapter was to examine effect of aza A on mitosis of onion root tips. The limonoids in concentration of 10-3 M adversely affected the mitotic activity of onion root tip cells. This could be failure of microtubules polymerisation into microtubules, or some other biochemical effect. From the findings in this part of the project, it can be concluded that only at a concentration of 10-3 M is aza A toxic to plant young seedlings, but in practice this is unlikely to be a significant problem. The first part of Chapter 4 of the project was to lay the foundations for the behaviour of aza A in soil environment in both powder form and in 2 types of granular formulations. The half-life of azadirachtin in soil from this work was found to be 1.6 days which is consistent with the previous reports. This short half-life of aza A may be problematic in use as a PPP. The short persistence might be overcome by formulating neem materials in granules to achieve environmental stability and biological efficacy of application. The granular formulations used in the project showed controlled release characteristics. The release of azadirachtin into the soil water was in fact delayed by encapsulating it in pellets. Systemic uptake of aza A by roots and subsequent presence in the vascular system of plants was assessed. Aza A was transported and was more stable in the leaf areas of cabbage and sugar beet plants than in the soil, as the half-life was found to be 9 days. The concentration of aza A in the leaf-water was less than 10% of the solution bathing the roots. The final part of the project, the application of the pelleted NSKE to protect cabbage, in both glass house and field conditions, demonstrated that neem products in pelleted formulations could be used as effective, systemically applied PPP to control pests of cabbage. In the field tests, the protective effect of the neem extract could be shown over a period of at least 5 weeks after addition of the pellets to the soil. In conclusion, the short soil half-life of the neem a.i., aza A, in PPP could be overcome by a pelleted formulation, the composition of which can delay release of the a.i. The technology allows protection of crops from soil-borne, as well as foliar sucking and biting pest damage by controlled release into the soil to allow uptake into plant vascular system.

Abstract:
De nos jours, il y a une volonté générale de se tourner vers une agriculture plus respectueuse de l’environnement et du consommateur se traduisant notamment par une démarche de réduction des intrants chimiques. Dans un contexte de développement durable, la recherche de produits naturels pour lutter contre les maladies et les ravageurs suscite un regain d’intérêt. Dans cette thèse, des extraits hydro-alcooliques issus de coproduits de la vigne (sarment, cep, racine) et d’essences forestières (écorce d'épicéa, nœud de pin) se sont révélés être une excellente source de polyphénols bioactifs, en particulier en stilbènes complexes. En effet, ces extraits ont démontré un large spectre d’activités contre différentes maladies végétales. En particulier, un potentiel oomycide contre le mildiou de la vigne et une capacité insecticide contre un parasite des Solanacées sont rapportés. En outre, la pertinence de l'utilisation de la « chimie verte » pour extraire les stilbènes comme méthode alternative aux solvants organiques a été mise en évidence. Les présents résultats renforcent une voie de recherche originale pour faire progresser une viticulture et une agriculture plus durables, en utilisant des produits de biocontrôle moins toxiques et biodégradables, constituant ainsi une solution possible et réaliste pour lutter contre les pathogènes des plantes
Nowadays, is a priority to turn towards a more eco- and consumer friendly agriculture resulting in the reduction of the chemical inputs. In a context of a sustainable development, the investigation of natural products to fight against diseases and pests raised a renewed interest. In this thesis, hydroalcoholic extracts derived from grapevine (cane, wood, root) and forest species (spruce bark, pine knot) by-products have demonstrated to be a great source of bioactive polyphenols, and particularly in complex stilbenes. Indeed, these extracts have proved to confer a broad spectrum of activities against different major plant diseases. In particular, an oomycide potential against downy mildew of the vine and an insecticidal capacity against Solanaceae pest were reported. Furthermore, the relevant use of “green chemistry” to extract stilbenes as an alternative method of organic solvents has been highlighted. The present findings strengthen an original line of research to advance in a more sustainable viticulture and agriculture, using less toxic and biodegradable biocontrol products, being this a possible and realistic solution to combat plant pathogens

Abstract:
Protection management with the aid of plant protection products makes it possible to carry out pest control programs in agricultural environments and make them less hazardous for the cultivation of products on a large scale. However, when these programs are put into effect, only a small proportion of the sprayed products is really deposited on the target area while much of it is carried to neighboring regions. The scientific literature includes studies on the use of mathematical techniques to calculate the physical transformation and movement and provide a deposition estimate of the product. On the basis of this prediction, it is possible to configure a system which can allow the spraying to be carried out in normal weather conditions in the region for a satisfactory performance, although these conditions can undergo changes and make any statistical configuration unreliable. An alternative way of overcoming this problem, is to adapt the spray elements to the meteorological conditions while the protection management is being undertaken. However, the current techniques are operationally expensive in computational terms, which makes them unsuitable for situations where a short operational time is required. This thesis can be characterized as descriptive and seeks to allow deposition predictions to be made in a rapid and precise way. Thus it is hoped that the new approaches can enable the spray element to be adapted to the weather conditions while the protection management is being carried out. The study begins by attempting to reduce costs through a computational model of the environment that can speed up its execution. Subsequently, this computational model is used for predicting the rate of deposition as a fitness function in meta-heuristic algorithms and ensure that the mechanical behavior of the spray element can be adapted to the weather conditions while the management is put into effect. The results of this approach show that it can be adapted to environments with low variability. At the same time, it has a poor performance in environments with a high variability of weather conditions. A second approach is investigated and analyzed for this scenario, where the adaptation requires a reduced execution time. In this second approach, a trained machine learning technique is employed together with the results obtained from the first approach in different scenarios. These results show that this approach allows the spray element to be adapted in a way that is compatible with what was provided by the previous approach in less space of time.
O manejo de proteção com uso de produtos fitofarmacêuticos possibilita o controle de pragas em ambientes agrícolas, tornando-o menos nocivo para o desenvolvimento da cultura e com produção em grande escala. Porém, apenas uma pequena parte do produto pulverizado realmente é depositado na área alvo enquanto a maior parte do produto sofre deriva para regiões vizinhas. A literatura científica possui trabalhos com o uso de técnicas matemáticas para calcular a transformação física e movimento para estimar a deposição do produto. Com base nessa predição é possível configurar o sistema de pulverização para realizar a pulverização sob uma condição meteorológica comum na região para um desempenho satisfatório, mas as condições meteorológicas podem sofrer alterações e tornar qualquer configuração estática ineficiente. Uma alternativa para esse problema é realizar a adaptação da atuação do elemento pulverizador às condições meteorológicas durante a execução do manejo de proteção. Contudo, as técnicas existentes são computacionalmente custosas para serem executadas, tornando-as inadequadas para situações em que é requerido baixo tempo de execução. Esta tese se concentra no contexto descrito com objetivo de permitir a predição da deposição de forma rápida e precisa. Assim, espera-se que as novas abordagens sejam capazes de possibilitar a adaptação do elemento pulverizador às condições meteorológicas durante a realização do manejo de proteção. Este trabalho inicia com o processo de redução do custo de execução de um modelo computacional do ambiente, tornando sua execução mais rápida. Posteriormente, utiliza-se este modelo computacional para predição da deposição como função Fitness em algoritmos de meta-heurística para adaptar o comportamento do elemento pulverizador às condições meteorológicas durante a realização do manejo. Os resultados desta abordagem demonstram que é possível utilizá-la para realizar a adaptação em ambientes com baixa variabilidade. Por outro lado, pode apresentar baixo desempenho em ambientes com alta variabilidade nas condições meteorológicas. Uma segunda abordagem é investigada e analisada para este cenário, onde o processo de adaptação requer um tempo de execução reduzido. Nesta segunda abordagem é utilizado uma técnica de Aprendizado de Máquina treinada com os resultados gerados pela primeira abordagem em diferentes cenários. Os resultados obtidos demonstram que essa abordagem possibilita realizar a adaptação do elemento pulverizador compatível com a proporcionada pela abordagem anterior em um menor espaço de tempo.

Abstract:
Abstract Technologies based on RNA interference (RNAi) may be used in plant production in different contexts. With respect to applicable regulations, a major distinction is to be made between plants producing small RNA molecules due to modifications of the genome and topically applied plant protection products (PPPs) based on double-stranded RNA (dsRNA).

Abstract:
Abstract Technologies based on RNA interference (RNAi) may be used in plant production in different contexts. With respect to applicable regulations, a major distinction is to be made between plants producing small RNA molecules due to modifications of the genome and topically applied plant protection products (PPPs) based on double-stranded RNA (dsRNA). The first group may be further divided into those using RNAi technology to achieve changes in the plant's metabolism and those where plant-produced RNA molecules are intended to impact other organisms that interact with the plant. For PPPs, relevant aspects are whether the product contains living organisms or only purified molecules. The intended use of the product is another relevant aspect with respect to regulation. It is expected that PPPs will be among the first products utilizing the RNAi mechanism in the European Union. This chapter discusses the regulation of modified RNAi plants and the regulation of PPPs utilizing RNAi mechanisms.

Considering the growing demand for organic production of food and registration-related problems, the number of pest management products that can be used in this sort of production is limited. In this study the efforts have been made to formulate the Neem oil emulsions which would be used as agrochemicals. Bioassays were performed on aphids (Myzodes persicae Sulz., Aphis gossypii Glow , Aphis pomi Deg.) in order to compare the insecticidal activity of the neem oil new preparative form NEEM-01 with that of the commercial biorational product Pelecol EO. The bioassays conducted on the aphids demonstrated that the NEEM-01 aplicated at the doze 8,0 l/ha was not effective as the commercial product Pelecol EO. But at the doze 10,0 l/ha new preparative form of neem oil has demonstrated a good biological effectiveness during 7 days after two treatments.

Full text
Abstract:
Underground Coal Gasification (UCG) is a gasification process carried on in non-mined coal seams using injection and production wells drilled from the surface, converting coal in situ into a product gas usable for chemical processes and power generation. The UCG process developed, refined and practiced by Ergo Exergy Technologies is called the Exergy UCG Technology or εUCG® Technology. The εUCG technology is being applied in numerous power generation and chemical projects worldwide. These include power projects in South Africa (1,200 MWe), India (750 MWe), Pakistan, and Canada, as well as chemical projects in Australia and Canada. A number of εUCG based industrial projects are now at a feasibility stage in New Zealand, USA, and Europe. An example of εUCG application is the Chinchilla Project in Australia where the technology demonstrated continuous, consistent production of commercial quantities of quality fuel gas for over 30 months. The project is currently targeting a 24,000 barrel per day synthetic diesel plant based on εUCG syngas supply. The εUCG technology has demonstrated exceptional environmental performance. The εUCG methods and techniques of environmental management are an effective tool to ensure environmental protection during an industrial application. A εUCG-IGCC power plant will generate electricity at a much lower cost than existing or proposed fossil fuel power plants. CO2 emissions of the plant can be reduced to a level 55% less than those of a supercritical coal-fired plant and 25% less than the emissions of NG CC.

Full text
Abstract:
The intent of this proposal was to study the interaction between nonpathogenic mutants of Colletotrichum magna and Fusarium oxysporum, and the cucurbit host defense system. We had shown previously that a nonpathogenic endophytic mutant path- 1 of C. magna, caused no visible disease symptoms but protected watermelon seedlings from disease caused by the wildtype isolate and F. o. niveum. Objectives were: 1) Determine the microscopic, biochemical and molecular genetic interaction between "protected" (path- 1 colonized) cucurbit hosts and wildtype isolates of C. magna; 2) Isolate non-pathogenic mutants of F.o. melonis and test feasibility for protecting plants against fungal diseases. We found that path-1 caused no visible disease symptoms in cucurbit seedlings but conferred disease resistance against pathogenic isolates of C. magna, C. orbiculare, and F. oxysporum. Disease resistance conferred by path-1 correlated to a decrease in the time of activation of host defense systems after exposure of path-1 colonized plants to virulent pathogens. This was determined by monitoring the biochemical activity of PAL and peroxidase, and the deposition of lignin. It appears that path-1-conferred disease resistance is a multigenic phenomenon which should be more difficult for pathogen to overcome than single gene conferred resistance. Based on the benefits conferred by path-1, we have defined this mutant as expressing a mutualistic lifestyle. REMI (restriction enzyme-mediated integration) nonpathogenic mutants were also isolated using pHA1.3 plasmid linearized with Hind III and transformed into wildtype C. magna. The integrated vector and flanking genomic DNA sequences in REMI mutant R1 was re-isolated and cloned resulting in a product of approximately 11 kb designated pGMR1. Transformations of wildtype C. magna with pGMR1 resulted in the same non-pathogenic phenotype. A nonpathogenic mutant of F.o. melonis (pathogenic to melon) was isolated that colonized melon plants but elicited no disease symptoms in seedlings and conferred 25 - 50% disease protection against the virulent wildtype isolate. Subsequently, nonpathogenic mutant isolates of F.o. niveum (pathogenic to watermelon) were also isolated. Their protection capacity against the respective wildtype parent is currently under investigation. This research has provided information toward a better understanding of host-parasite interactions; specifically, endophytes, pathogens and their hosts. It will also allow us to assess the potential for utilizing nonpathogenic mutants as biological control agents against fungal pathogens and isolating molecular genetic factors of pathogenicity in Fusarium.

Abstract:
Citrus tristeza virus (CTV) has the largest genomes among RNA viruses of plants. The 19,296-nt CTV genome codes for eleven open reading frames (ORFs) and can produce at least 19 protein products ranging in size from 6 to 401 kDa. The complex biology of CTV results in an unusual composition of CTV-specific RNAs in infected plants which includes multiple defective RNAs and mixed infections. The complex structure of CTV populations poses special problems for diagnosis, strain differentiation, and studies of pathogenesis. A manipulatable genetic system with the full-length cDNA copy of the CTV genome has been created which allows direct studies of various aspects of the CTV biology and pathology. This genetic system is being used to identify determinants of the decline and stem-pitting disease syndromes, as well as determinants responsible for aphid transmission.

Full text
Abstract:
The objectives of the research in this proposal were to (A) identify synergy among proteins that provide enhanced activity over single proteins for control of plant pathogenic fungi, (B) clone and characterize genetic sequences coding for proteins with ability to control pathogenic fungi, (C) produce transgenic organisms with enhanced biocontrol ability using genes and gene combinations and determine their efficiency in protecting plants against plant pathogenic fungi. A related objective was to produce disease-resistant plants. Fungal cell wall degrading enzymes from any source are strongly synergistic with any membrane active compound and, further, different classes of cell wall degrading enzymes are also strongly synergistic. We have cloned and sequenced a number of genes from bacterial and fungal sources including five that are structurally unrelated. We have prepared transgenic fungi that are deficient in production of enzymes and useful in mechanistic studies. Others are hyperproducers of specific enzymes that permit us, for the first time, to produce enzymes from T. harzianum in sufficient quantity to conduct tests of their potential use in commercial agriculture. Finally, genes from these studies have been inserted into several species of crop plants were they produce a high level of resistance to several plant pathogenic fungi.

Full text
Abstract:
Iron is the fourth most abundant element in the soil, but since it forms insoluble hydroxides at neutral and basic pH, it often falls short of meeting the basic requirements of plants and microorganisms. Most aerobic and facultative aerobic microorganisms possess a high-affinity Fe transport system in which siderophores are excreted and the consequent Fe complex is taken up via a cognate specific receptor and a transport pathway. The role of the siderophore in Fe uptake by plants and microorganisms was the focus of this study. In this research Rhizopus arrhizus was found to produce a novel siderophore named Rhizoferrin when grown under Fe deficiency. This compound was purified and its chemical structure was elucidated. Fe-Rhizoferrin was found to alleviate Fe deficiency when applied to several plants grown in nutrient solutions. It was concluded that Fe-Rhizoferrin is the most efficient Fe source for plants when compared with other among microbial siderophores known to date and its activity equals that of the most efficient synthetic commercial iron fertilizer-Fe EDDHA. Siderophores produced by several rhizosphere organisms including Rhizopus Pseudomonas were purified. Monoclonal antibodies were produced and used to develop a method for detection of the siderophores produced by plant-growth-promoting microorganisms in barley rhizosphere. The presence of an Fe-ferrichrome uptake in fluorescent Pseudomonas spp. was demonstrated, and its structural requirements were mapped in P. putida with the help of biomimetic ferrichrome analogs. Using competition experiments, it was shown that FOB, Cop B and FC share at least one common determinant in their uptake pathway. Since FC analogs did not affect FOB or Cop-mediated 55Fe uptake, it could be concluded that these siderophores make use of a different receptor(s) than FC. Therefore, recognition of Cop, FOB and FC proceeds through different receptors having different structural requirements. On the other hand, the phytosiderophores mugineic acid (MA and DMA), were utilized indirectly via ligand exchange by P. putida. Receptors from different biological systems seem to differ in their structural requirements for siderophore recognition and uptake. The design of genus- or species-specific drugs, probes or chemicals, along with an understanding of plant-microbe and microbe-microbe relationships as well as developing methods to detect siderophores using monoclonal antibodies are useful for manipulating the composition of the rhizosphere microbial population for better plant growth, Fe-nutrition and protection from diseases.

Full text
Abstract:
In intensive agriculture, harmful soilborne biotic agents, cause severe damage. These include both typical soilborne (clinical) major pathogens which destroy plants (e.g. Fusarium and Phytophthora pathogens), and subclinical ("minor") pathogens (e.g. Olpidium and Pythium). The latter cause growth retardation and yield decline. The objectives of this study were: (1) To study the behavior of clinical (major) and subclinical (minor) pathogens in plant growth substrate, with emphasis on zoosporic fungi, such as Pythium, Olipidium and Polymyxa. (2) To study the interaction between subclinical pathogens and plants, and those aspects of Pythium biology which are relevant to these systems. (3) To adopt a holistic-integrated approach for control that includes both eradicative and protective measures, based on a knowledge of the pathogens' biology. Zoospores were demonstrated as the primary, if not the sole propagule, responsible for pathogen spread in a recirculating hydroponic cultural system, as verified with P. aphanidermatum and Phytophthora capsici. P. aphanidermatum, in contrast to Phytophthora capsici, can also spread by hyphae from plant-to-plant. Synthetic surfactants, when added to the recirculating nutrient solutions provided 100% control of root rot of peppers by these fungi without any detrimental effects on plant growth or yield. A bacterium which produced a biosurfactant was proved as efficacious as synthetic surfactants in the control of zoosporic plant pathogens in the recirculating hydroponic cultural system. The biosurfactant was identified as a rhamnolipid. Olpidium and Polymyxa are widespread and were determined as subclinical pathogens since they cause growth retardation but no plant mortality. Pythium can induce both phenomena and is an occasional subclinical pathogen. Physiological and ultrastructural studies of the interaction between Olpidium and melon plants showed that this pathogen is not destructive but affects root hairs, respiration and plant nutrition. The infected roots constitute an amplified sink competing with the shoots and eventually leading to growth retardation. Space solarization, by solar heating of the greenhouse, is effective in the sanitation of the greenhouse from residual inoculum and should be used as a component in disease management, along with other strategies.
