Hanik, Nur Rokhimah, and Rohmad Faoji. "Identification of Pests and Diseases on Anthurium Plants (Anthurium andraeanum) in Sewu Kembang Tourism Village, Karanganyar." Jurnal Biologi Tropis 21, no. 3 (October 13, 2021): 993–1002. http://dx.doi.org/10.29303/jbt.v21i3.2973.
Full textAbstract:
Anthurium ornamental plants are currently very popular among ornamental plant lovers, both from the charm of the type and color and the high price. Although pests and diseases in anthurium are not very disturbing, if left unchecked it will greatly interfere with the beauty, inhibit growth and be detrimental to collectors and sellers/entrepreneurs of these ornamental plants. The purpose of this study was to determine the types of pests and diseases that attack anthurium plants. This research was carried out in the Sewu Kembang Nglurah Tourism Village, Tawangmangu Regency, Karanganyar Regency, for 30 days from Saturday, September 4 to October 3, 2021. This study used 20 samples of Anthurium plants. The tools used were cellphone cameras and stationery. The variables that will be observed are pests and diseases that attack Anthurium. This research used observation and interview methode, the data obtained were analyzed by qualitative descriptive. The results of this study found several pests and diseases on anthurium plants that caused the plant leaves and flowers to have holes, shriveled, yellowed spots, slimy, and caused stunted growth. The pests found were caterpillars and snails, while the diseases included fungus, chlorisis, leaf rust, anthracnose, curly leaves, and burnt leaves.

Full textAbstract:
Parijoto (Medinilla speciosa blume) is a tropical plant that has purplish pink fruit often called Asian grape. In Indonesia, parijoto plants are very well known as ornamental plants that have various benefits, from parijoto fruit can be used as anti-inflammatory drugs so that ornamental plants are widely cultivated by the community, especially lovers of ornamental plants and ornamental plant cultivation in Nglurah. Medinilla speciosa blume is very suitable in Indonesia, which has a tropical climate, but the high rainfall in Indonesia in the rainy season should get more attention in caring for it. This makes parijoto plants susceptible to several types of diseases and pests that can damage the beauty of the Medinilla speciosa blume plant. However, the lack of experts in this field makes it very difficult for plant lovers and the cultivation community of Medinilla speciosa blume in Nglurah to solve the problem of diseases and pests that attack the Medinilla speciosa blume plant. The purpose of this study was to determine pests and diseases on Medinilla speciosa blume. This research was conducted in Nglurah Village Rt 01 Rw 02 Tawangmangu for five days on 04 ââ¬â 08 September 2021. This research uses observation and interview methods. Data were analyzed by qualitative descriptive. This study used 10 samples of the observed Medinilla speciosa blume plant. The tools used are cellphone cameras and stationery. The variables to be observed are pests and diseases. The results of this study found 4 pests and 2 diseases on Medinilla speciosa blume including Fussarium oxysporum, Cercospora sp and Pestalotia sp, mealybugs, caterpillars, snails, grasshoppers. For this reason, the solution for treating parijoto plants to avoid pests and diseases requires extra care such as paying attention to soil moisture, giving appropriate fertilizers, and giving vitamins so that parijoto plants can grow well.

Full textAbstract:
Alocasia longiloba is a popular ornamental plant in China, however pests and diseases associated with A. longiloba reduce the ornamental value of this plant. From 2016 to 2021, stem and root rot has been observed on A. longiloba in Guangdong Province, China. Once the disease became severe, plants wilted and died. A fungus was isolated from the diseased stem and identified as Fusarium elaeidis using both morphological characteristics and molecular analysis of DNA-directed RNA polymerase II subunit (rpb2), translation elongation factor-1α (tef1) gene and β-tubulin (tub2) sequence data. The pathogenicity test showed the fungus was able to produce typical symptoms on A. longiloba similar to those observed in the field. The original pathogen was reisolated from inoculated plants fulfilling Koch’s postulates. This is the first report of Fusarium elaeidis causing stem rot on A. longiloba. These results will provide a baseline to identify and control diseases associated with A. longiloba.

Full textAbstract:
Rose is one of the most important ornamental plants in Indonesia. Almost 57.02% of the national cut rose’s demand was supplied from East Java, mainly from Batu. However, in the production process, there are various problems, especially pest and disease damages. In this regard, a study was conducted to determine recent status of the pests and diseases on roses in cultivation center of Batu, East Java. Observation was carried out in the farmers’ field randomly, from October to December 2014. Observation was performed on type and damage intensity of the pests and diseases. The pests and plant damage were sampled for further identification. An interview was made with some farmers to get secondary data about the type and the importance of the pests and diseases as well as the effort for controlling them. The result showed that some pests and diseases found included aphid, armored scale insect, spider mite, thrips, black spot, crown gall and powdery mildew. Based on morphological identification, there were two families of armored scale insect, i.e., Coccidae and Diaspidae. The highest damage intensity was due to armored scale insect, thrips, black spot and crown gall with the percentage of damage intensities of 50.50%, 20.00%, 45.50% and 65.00%, respectively. Based on those data, scale insect, thrips, black spot and crown gall were classified as important pests and diseases on roses in this area. Some pesticides and other materials like petroleum oil and detergent were used by the farmers to control either pests or diseases, but they were ineffective, especially in controlling armored scale insect and crown gall.

Full textAbstract:
Laser-guided variable-rate intelligent spray technology is anticipated to reduce pesticide use in production of crops and safeguard the environment. However, the ability of this technology to effectively control insect pests and diseases of crops must be validated before it becomes part of integrated pest management programs. Abilities of three different intelligent sprayers were tested to control pest insects and plant diseases at one fruit farm and two ornamental nurseries in Ohio during three consecutive growing seasons. The same sprayers with disabled intelligent functions were used as conventional constant-rate applications for comparisons. Test crops were apple (Malus pumila), peach (Prunus persica), blueberry (Vaccinium sect. Cyanococcus), black raspberry (Rubus occidentalis), crabapple (Malus sp.), maple (Acer sp.), birch (Betula sp.), and dogwood (Cornus florida). There were five insects and six diseases total involved in the investigations in the fruit farm and two nurseries. The field tests showed the intelligent spray applications reduced pesticide and foliar fertilizer use by ≈30% to 65% on average during the 3-year experiments. At the same time, intelligent spray technology was similar or more effective than conventional spray technology when controlling insects and diseases on a variety of crops. These results demonstrated that intelligent spray technology was environmentally friendly and more effective for control of insect and disease pests in fruit farms and ornamental tree nurseries.

Full textAbstract:
Abstract Current label recommendations of pesticides for arthropod pests and plant diseases in the nursery and green industry are vague and frequently result in excessive pesticide use. The objective of this research was to demonstrate that modifications of spray application techniques with current spray equipment in ornamental nursery production could reduce pesticide use. The efficacy of half rates and full rates of both active ingredients and carrier was investigated in commercial nurseries with air-assisted sprayers in two tests and a state inspector survey for the control of arthropod pests and plant diseases. Sprayers were optimized with properly sized nozzles and properly calibrated operating parameters. In Test 1, treatments were conducted in approximately 0.5 ha (1.2 A) plot each in three commercial nurseries for control of arthropod pests and diseases, and in Test 2, the same treatment for aphid control was evaluated in a birch tree plot. The survey was a compilation of the pests and diseases that were diagnosed by state inspectors in over 2,800 plant varieties and species from two commercial nursery fields [total about 280 ha (692 A)] after the spray treatments in six growing seasons. Crop damage by 49 insects and 40 diseases were surveyed for different application rates. The studies revealed that insect and disease control using 50% of the label rates was as effective as full rates when quality spray coverage on targets was achieved, resulting in real cost benefits to producers, consumers and the environment.

Full textAbstract:
Lagerstroemia is a genus of plants comprised of deciduous shrubs or small trees native to China southward into Southeast Asia. L. indica, the oldest and most widespread species in cultivation in the United States, has been cultivated as an ornamental for centuries and was introduced to the Southeastern U.S. over 175 years ago. Much has been disseminated on the culture and commercial production of crapemyrtle species and cultivars; including plant forms and function, adaptability to macro and micro environment, growth and floral characteristics, and commercial production and landscape culture and maintenance. Since the introduction of L. indica in the United States, L. fauriei, L. subcostata and L. limii have also been introduced. However, since the mid 1970s, interspecific hybrids between L. indica × L. fauriei comprise the majority of new cultivar introductions. Breeding efforts have resulted in 133 commercially available cultivars as of December 2011 that include cultivars with ever improving form and flowering, new flower colors, ornamental bark, ornamental foliage, and disease tolerance. However, there is a wide range among cultivars of tolerance to key pests and diseases such as powdery mildew, Cercospora leaf spot, flea beetle and Japanese beetle. A large number of pests and plant pathogens also negatively affect crapemyrtle health including granulate ambrosia beetle, crapemyrtle aphid, bark scale, bacterial leaf spot, sooty mold and soil-borne root and crown diseases. This review focuses on crapemyrtle culture, in both commercial and landscape settings, with an emphasis on optimizing plant health through the discussion of major abiotic and biotic stressors and cultivar variation in tolerance to these stressors.

Full textAbstract:
The genus, Magnolia, encompasses a group of about 240 species of evergreen or deciduous trees and large shrubs. Magnolias are native to temperate, subtropical and tropical areas of southeastern Asia, eastern North America, Central America, the Caribbean and parts of South America. Native and nonnative Magnolia species have become prominent landscape plants in the southeastern U.S. due to their beauty, utility, relative ease of maintenance and broad adaptability to the region's climate and soils. Species introductions, breeding and selection programs over the last 50 years have produced superior selections with improved flowering, new flower colors and ornamental foliage and buds often featuring brown, copper or gold indumentum. Magnolia health and pest management is sometimes overlooked in both landscape and production settings because magnolia is considered to have relatively few pest and disease problems. Some abiotic disorders may mimic biotic damage or may render magnolia more susceptible to pests and diseases. When they occur, abiotic disorders, pests or diseases on magnolia can cause significant economic or aesthetic losses. This review focuses on magnolia culture in production and landscape settings with an emphasis on major pests, plant diseases and abiotic disorders affecting management of Magnolia species.

Full textAbstract:
There are two primary forms of plant propagation: sexual and asexual. In nature, propagation of plants most often involves sexual reproduction, and this form is still used in several species. Over the years, horticulturists have developed asexual propagation methods that use vegetative plant parts. Innovation in plant propagation has supported breeding programs and allowed the production of high-quality nursery plants with the same genetic characteristics of the mother plant, and free of diseases or pests. The purpose of this Special Issue, “Innovation in Propagation of Fruit, Vegetable and Ornamental Plants”, was to present state-of-the-art techniques recently developed by researchers worldwide. The Special Issue has brought together some of the latest research results of new techniques in plant propagation in nine original papers, which deal with a wide range of research activities.

Full textAbstract:
Although lawn care and landscape maintenance professionals appear increasingly willing to use Integrated Pest Management (IPM) strategies and adopt nonchemical pest management alternatives into management practices, the opinions of landscape management professionals have not been assessed regarding anticipated influences of increased use of insect- and disease-resistant ornamental plants on grounds management activities, client satisfaction, or business profitability. Lawn care and landscape professionals are well positioned to implement many IPM practices into landscape use and to educate their consumer clients about ecologically sustainable landscape designs and beneficial management techniques. Conversely, if some of these professionals are unwilling to advocate installation of ornamental host plants that are resistant to certain pests or diseases, market success of such plants can be limited. To better understand perceptions of green industry professionals related to these issues, we surveyed lawn care and landscape business owners and employees to categorize their perceptions about insect- or disease-resistant ornamental plants and qualified their beliefs in relation to both personal and firm demographics. A total of 391 completed surveys were received from Tennessee, Florida, and Georgia participants. Data analyses revealed that lawn care and landscape maintenance professionals largely believe that insect- and disease-resistant plants will benefit their businesses and should result in increased client satisfaction. Only ≈4% of respondents stated concern that business would incur at least some negative effect if pest-resistant plants were made more available or used in greater numbers in client landscapes. Among all respondents, there was an average expectation that 60% or more of plants within a given client's landscape would have to be resistant to insect pests or plant diseases to result in a decrease in company profits. If insect- and disease-resistant ornamental plants were used more widely in client landscapes, respondents expected that the required number of site visits to client landscapes would remain unchanged and that moderate reductions in insecticide and fungicide use would result.

Chrysanthemum is a floricultural, ornamental and medicinal plant with tremendous income cash crop which is cultivated chiefly in winter. The crop charity as nerve sedative, anti-oxidant, anti-inflammatory, anti-mutagenic, anti-microbial, anti-fungal, anti-angiogenic, anti-atherosclerosis and nematocidal goods. Chrysanthemum has been used for hundreds of years in manufacturing medicine. It is used to treat respiratory complications, high blood pressure, and hyperthyroidism and reduce inflammation. Leaves remedies for colds, headaches, bronchitis, rheumatism, and swellings. The plant has aesthetic significance as well. Nevertheless, outbreaks of pests and diseases have hold back Chrysanthemum cultivation in Bangladesh. Insect pest damages the plant directly by sucking cell sap and indirectly spread out of virus diseases as act of vector. Aphid resistance variety might be the effective tool for successful production of chrysanthemum plant. Sustainable crop disease management for Chrysanthemum needs a multitude of consideration of the impacts of management methods on economics, sociology and ecology by wholly understanding the mechanisms of crop disease epidemics and the functioning of normal agroecosystems. The findings of this study present clear insights into efforts that will encourage farmers to adopt effective and ecological methods of pest and disease management for successful chrysanthemum production in Bangladesh.

Full textAbstract:
In this paper, one of the most specific groups of plant entomologists, that of the U/Order Coccoinea Class Insecta is taken into analysis.
Below it is seen important to identify the problems of infections of a variety of ornamental plants, found in the Southern Region of Albania, precisely by this group of pests. The role of the quality of the natural environment in our health has recently taken tremendous priority in the context of the contamination of all forms in the wild nature and especially those in the air. Precisely, to increase the quality of our life, the establishment of major parks with a truly significant green space per unit of population, is one of the current main objectives of each country. In these conditions, those environments are pretty rich in a variety of plants that, in addition to the functional values of environmental creativity, also have many aesthetic values with relaxing power and positive effects on our physical and mental health This type of plants is represented not only by those that are cultivated directly in the nature, but also by those that are planted and cultivated in greenhouses, which from time to time we take them out to realize the required decorations and compositions, asked to cover the needs of the parks. The healthier these components of this environment are, the more effective is their role on our personal health. For this reason it is equally important to recognize the dangers that threaten this vegetation by disabling its main function, for which we, as citizens, are interested, due to the need of our health, to have it in the highest efficiency. On this basis arose the idea of a comprehensive study on the above group of insects, which in a form or another constitute some of its main pests. These insects, as a specific group of pests that feed on plant lymph, not only dry out the plant, but also transmit to it a series of viral diseases, leading the plant to complete degradation. Most of them spend the winter (one of the most delicate periods for their survival) as parasites on them. We show below, which of these entomophytes is found in this group of plants in the region in question. It is also shown, which of the analyzed plant species emerges as the most frequented by this group of pests. We also identify the prevalence of this pollution in both variety and percentage. On the basis of the analysis, the question is also what is the distribution of plant species encountered, at different altitudes above the sea level? The paper contains, figuratively, a series of morpho-defining characteristics of the representatives, mentioned in this paper. As will be seen in the following material, the truth is that this specific group of ornamental plants, part of the relaxing parks around the world, in our country turns out to be contaminated by a large number of these parasites. This shows that in order to carry out quality work in this direction, we must not leave without considering the role of these pests in this process. Thus, we will be able to control the quality and function of our recreational environments in the role, for which we realize them. For this reason, detailed data are given below. We have identified these parasites in about 15 (fifteen) species of these ornamental plants, taking into account that parks in our country are not valued for the size of the area, as in an inferior and small country. In this material we have identified the number and dynamics of parasites according to each plant and also according to their distribution in areas with different altitudes above the sea level. We also give a comparative report on the frequency of vulnerability of the various plants by representatives of these pests. Summarized in a table, we have given for each pest the plant variety that it frequents, noting, in which plant organ this parasite was most commonly found during our research. As it is a group with annual activity on the plants, we have data for each month that we have met them on this vegetation and for each plant organ, where they were met (in leaves, on stalks or even the fruit itself). Regarding the degree of the damage that they cause to the plants, given the many harmful valences they show, not all belong to the category of the very dangerous pests. Some enter the minor pests that are mostly caused by overlapping other diseases, some others into the normal pests and a more specific group enters the category of very powerful pests, the risk of which is maximized with other additional effects. These and other information are given in table Number 1 (one), with the required symbolism.
Since this group of plants is the environmental generator, where we live and work, the work in question takes on practical importance and value

Abstract Intelligent spray technology can reduce pesticide use and safeguard the environment; however, its ability to effectively control insects and disease must be validated before its adoption by growers. Comparative tests for two different laser-guided variable-rate intelligent sprayers and the same sprayers with conventional constant-rate mode were conducted to control pests at two ornamental nurseries in two growing seasons in Ohio. Crabapple [Malus ‘Sutyzam’ (Sugar Tyme®), M. sargentii], apple (Malus pumila), maple [Acer ×freemanii ‘Jeffersred' (Autumn Blaze®), A. rubrum ‘Franksred' (Red Sunset®) and A. rubrum], birch (Betula nigra and Betula populifolia ‘Whitespire'), London planetree (Platanus ×acerifolia ‘Bloodgood') and dogwood (Cornus florida) were used as the test plants. Intelligent spray technology reduced pesticide use by 56.1% and 51.8% on average at the two nurseries, respectively. Compared to conventional air-assisted sprayers, severity of scab on apple trees and powdery mildew in dogwood was reduced on intelligent spray-treated plants at one nursery, and there were equal or fewer leafhoppers in maple trees and aphids in birch trees when sprayed using intelligent spray technology at both nurseries. These results suggest that intelligent, variable-rate sprayers achieve equivalent or greater insect and disease control in ornamental tree nurseries compared to conventional, constant-rate sprayers. Index words: aphid, apple scab, environmental protection, leafhopper, precision spray, powdery mildew, sustainable. Species used in this study: apple (Malus pumila Mill), birches (Betula nigra L, Betula populifolia Marsh. ‘Whitespire'), crabapples [Malus ‘Sutyzam' (Sugar Tyme®), M. sargentii Rehder], dogwood (Cornus florida L.), maples [Acer ×freemanii E. Murray ‘Jeffersred' (Autumn Blaze®), A. rubrum L. ‘Franksred'(Red Sunset®) and A. rubrum L.], London planetree [Platanus ×acerifolia (Ait.) Willd. ‘Bloodgood'].

The breeding of ornamental plants as a branch of crop production is an integral part of the set of measures aimed at obtaining a wide range of different plants with high decorative characteristics. The main objective of this branch is the creation of plants that are attractive to the consumer and commercially characterized by such valuable biological features as adaptability, resistance to diseases, pests, frost and others. Most ornamental plant varieties were bred by means of traditional breeding methods such as selection, distant hybridization, clone breeding, radiation and chemically induced mutagenesis. However, the use of traditional breeding tools is limited by the potential for intraspecific variability. The development of modern biotechnological and genetic approaches to the breeding of new varieties has made it possible to modify the plant genotype at a qualitatively new level. The present review covers the directions in and methodology of modern ornamental plant breeding in Russia, ways of mobilizing the genetic resources of the main ornamental crops such as rose, clematis, canna, chrysanthemum, pelargonia, iris, daylily, tulip, lilac, and rhododendron. Aslo, the review offers examples of ornamental plant breeding work uderway in the leading specialized scientific institutions such as the Russian State Agrarian University – the K.A. Timiryazev Moscow Agricultural Academy, I.V. Michurin Federal Research Centre, Nikitsky Botanical Gardens – National Scientific Center of the RAS, Subtropical Scientific Center of the Russian Academy of Sciences, Botanical Garden of the M.V. Lomonosov Moscow State University, All-Russian Scientific Research Institute of Tobacco, Mahorka and Tobacco Products. The world and Russian flower and ornamental plants markets, the problem and methods of resolving the issue of quality import substitution, and prospects for the development of floriculture in Russia in the foreseeable future are also briefly considered.

In the Podillya area, the most promising for greening different objects is the Lupine perennis L. and Lupine Polyphyllus Lindl. For creation of modern garden compositions of the park zone of Vinnytsia National Agrarian University the most appropriate are the varieties: Lulu-Russell, Minaret, Albus, Fireworks, which were well adapted to the growing conditions, were practically not affected by pests and diseases, were sufficiently resistant to environmental conditions. According to the flowering phase study, it was found that the highest flowering duration was observed in perennial lupine plants. In determining the suitability of the plants studied by us for their use in landscaping, their assessment of the complex of economic and biological indicators in accordance with the State Methodology of Variety Testing was carried out. Their high score on a set of criteria testifies to the prospect and suitability for cultivation in Podillia conditions, as well as the value for different uses: flower beds, ridges, mixboards, landscape type compositions and their smaller variants imitating natural groups.

Full textAbstract:
Species of the genus Aesculus are very attractive woody ornamentals. Their organs contain numerous health-promoting phytochemicals. The most valuable of them—aescin—is used in commercial preparations for the treatment of venous insufficiency. The industrial source of aescin is horse chestnut seeds because the zygotic embryos are the main site of its accumulation. Horse chestnut somatic and zygotic embryos contain similar amount of aescin, hence somatic embryos could be exploited as an alternative source of aescin. Somatic embryogenesis, androgenesis and de novo shoot organogenesis were successfully achieved in several Aesculus species, as well as secondary somatic embryogenesis and shoot organogenesis, which enables mass production of embryos and shoots. In addition, an efficient method for cryopreservation of embryogenic tissue was established, assuring constant availability of the plant material. The developed methods are suitable for clonal propagation of elite specimens selected as the best aescin producers, the most attractive ornamentals or plants resistant to pests and diseases. These methods are also useful for molecular breeding purposes. Thus, in this review, the medicinal uses and a comprehensive survey of in vitro propagation methods established for Aesculus species, as well as the feasibility of in vitro production of aescin, are presented and discussed.

Full textAbstract:
At the present development stage of the ornamental plants selection, there are almost no clear guidelines on the methodology for carrying out variety assessment. Applying the methods used in vegetable and fruit growing for the variety assessment of ornamental crops is incorrect due to the fact that when assessing varieties in ornamental gardening, the leading role belongs to such quality indicators as: color and shape of a leaf, flower or inflorescence, terry, aroma, number of peduncles etc. In addition, such important indicators for industrial floriculture or landscaping of territories as resistance to lodging, resistance to diseases and pests are taken into account indirectly. A characteristic feature of ornamental gardening, in contrast to vegetable growing and fruit growing, is the presence of a very wide variety of varieties within one species, differing in color, doubleness, height, field of use and other qualities, which is extremely important to take into account when carrying out a variety assessment. An integrated method of comparative variety assessment of ornamental plants, when converting all characteristics into relative values (points), simplifies selection and allows choosing the best varieties and hybrids in terms of decorative characteristics that best meet the requirements of modern production. At the same time, as a result of targeted selection, carried out within the relevant garden groups, a recommended assortment is formed, and it covers all existing typical flower colors, including early, middle and late varieties, in terms of flowering time, allowing to prolong the flowering of this crop. The developed methodology for a comprehensive assessment makes it possible to include in the modern assortment varieties that meet various purposes: for cutting in the open field, for forcing in greenhouse complexes and greenhouses, for landscaping gardens and parks.

The gardenia (Gardenia jasminoides Ellis) is a plant that is very appreciated in gardening for the beauty and fragrance of its flowers, attractive size and the intense green color of the foliage. In contrast to its ornamental qualities, it is not one of the most used plants in Cuba and other countries, so it is necessary to promote its cultivation. The present review objective was deepening and integrating information regarding the characteristics, utility, main pests and diseases and methods of propagation of the gardenia. The sunny and warm conditions during the day and fresh at night, relative humidity upper than 60% and acid soil, rich in iron, are favorable for this species development. Between the lesser known properties of gardenia, there are the medicinal ones because its extracts have diverse pharmacological effects. Its most common diseases are of fungal origin and provoke the rot roots and foliar spots. Among the pests that have the greatest incidence stand out the insects (aphids, citrus whitefly, coccids, and thrips). Gardenia plants can be propagated by different traditional methods (seeds, air layering, cuttings, and grafting), but the application of in vitro cultivation techniques are an efficient way to achieve this purpose, since it allows accelerated multiplication and production of healthy plants, also, it constitutes an alternative for obtaining secondary metabolites with pharmaceutical properties.

The purpose of the article is to describe the traditions of growing and using plants in the villages and small towns and to highlight the range of plants that were most often planted near houses during the 1970s and 80s in Ukraine. Methods. The study was conducted in the villages of Kyiv (Rogoziv), Zhytomyr (Hardyshivka) regions, in the suburbs of Kyiv (Bilychi, Zhulyany) and Borzna (Chernihiv region) by interviewing and eyewitness based accounts. Results. The article covers the list of traditional agricultural, fruit and ornamental plants for rural areas of Ukraine during the 1970s and 80s. The names of cultivars, methods of cultivation, meaning and traditional use of the plants are given. The peculiarities of the range of cultures depending on the studied area are analyzed. Conclusions. As a result of our research, the list of plants species grown in the villages of Ukraine during the 1970s and 80s included 104 species. Ornamental and food plants that were grown and used in the villages of Ukraine during the 1970s and 80s mostly were herbaceous annuals and perennials. A significant portion of them were vegetable fruit and berry plants. Among ornamental plants, medium- and tall plants with bright flowers and (or) strong aroma became more popular and widespread. These were species and cultivars that are easily propagated by seeds and division, do not require careful care and are resistant to diseases and pests.

Agriculture Faculty of UNIMAL is one of the leading faculties in the field of agriculture and fisheries development in Sumatra. The idea of introducing ornamental plant business prospects was based on the COVID-19 pandemic, which dealt a tremendous blow to the economy of the community around the UNIMAL Faculty of Agriculture. The majority of the people around the institution have house rentals for UNIMAL students. The COVID-19 pandemic condition in Aceh forced UNIMAL to change the offline education system to an online system according to the direction of the Ministry of Education and Culture. This is done to prevent the spread of the COVID-19 virus. In the online system, students carry out the learning process from their home region so they are not in the environment around UNIMAL. This has a direct impact on the people of East Reulet as a provider of rental houses. The solution that the team recommends is to turn into small and medium entrepreneurs who can generate additional income. The group of mothers can take advantage of their hobby, namely planting and collecting ornamental plants into an ornamental plant business that has great opportunities to be developed. The next solution is that housewives around Reulet Timur can use agricultural waste around them to be processed into bokashi plus fertilizer. Agricultural waste can damage the nutrient balance of the soil and invite pests and diseases in the surrounding area. The location of this activity is in Reuleut Timur Village, Muara Batu District, North Aceh Luaran Regency which is produced in the form of OJS-based service journals, online publications in mass media, and ornamental plant products and bokashi plus fertilizer which are ready to be marketed. The outputs of this service are articles in the IRPITAGE service journal Vol 1 (2) December 2021, news on activities on the fp.unimal.ac.id website, SPK (Cooperation Agreement) with partners and ornamental plant and fertilizer products.

Full textAbstract:
The great decorative diversity (shape and size of inflorescences, colouring and texture of leaves, varied intensity of growth) as well as big tolerance to habitat conditions, relatively small susceptibility to diseases and small sensitivity to 'ornamental grasses' pests favour their popularization in different gardens and urban areas. The examined species all may be recommended to plant in cooler east regions of Poland. Species which begin the earliest vegetation and flowering were <i>Calamagrostis</i> x <i>acutiflora</i> 'Karl Foerster' and <i>Deschampsia caespitosa</i> 'Goldtau'. These species, best planted separately or in small groups, can be also recommended in small garden compositions. For large areas, naturalistic gardens as well as structural plants of flowerbeds the best are <i>Calamagrostis</i> x <i>acutiflora</i> 'Karl Foerster', <i>Deschampsia caespitosa</i> 'Goldtau' and <i>Miscanthus sacchariflorus</i> 'Robusta'. <i>Phalaris arundinacea</i> L. is a typical ground covering grass with decorative leaves.

A national survey of the commercial ornamental industry was conducted to determine the current status of pest control including chemical and nonchemical disease control practices. The fungicides thiophanate methyl, chlorothalonil, mancozeb, and metalaxyl were used in the greatest quantity and by the largest percentage of growers. Metalaxyl was used in greenhouse and field operations by the highest percentage of growers, primarily to control root diseases but many growers reported using metalaxyl to control foliar disease. Overall, more fungicides were used in the field for foliar diseases, whereas almost equal amounts of fungicides were used for foliar and root diseases in the greenhouse.

Full textAbstract:
For the past 5 years, we have evaluated more than 100 herbaceous perennial groundcovers, including both grasses and grass mixtures, as well as ornamental broadleaf materials, for their ability to establish, suppress weeds, provide aesthetic appeal, and resist pests in various landscape and roadside settings across New York State. By working in cooperation with the NYSDOT, we have developed recommendations for materials that have performed well in difficult, potentially stressful, roadside and landscape settings. We have performed replicated research and demonstration trials that have clearly shown that certain species and cultivars provide effective weed suppression; great aesthetic appeal due to foliar texture, color, or flowering, resist pests and diseases; and require low maintenance over time. In addition, certain materials tolerate high levels of salt (NaCl), simulating roadside salt application exposure, in supplemental greenhouse studies. Materials generally suppressed weeds effectively by forming a dense canopy in a short period of time, and reducing light interception at the soil surface under this dense canopy. Certain groundcovers also appeared to exhibit strong potential allelopathic properties when grown either in field or laboratory settings. The selection of new plant materials for use in low-maintenance landscape settings offers potential to reduce time and maintenance inputs in difficult landscape or roadside settings, with the added benefit of reducing pesticide application in these settings for weed management. Additional studies are currently underway to develop further recommendations for use of warm- and cool-season turfgrasses in these settings.

Full textAbstract:
The ornamental horticulture industry in South Carolina has expanded significantly over the last decade. Today, concerns regarding environmental and public health, and stricter regulations of pesticide use, are creating incentives for growers to evaluate alternative methods of pest control. Nursery producers currently use an array of chemicals in an attempt to control pests including insects, weeds, and diseases. Integrated pest management (IPM) provides an opportunity to reduce chemical reliance. The overall objective of this extension program is to collect and collate information relevant to the implementation of an IPM program. The first year, 1989-90, surveys were developed to determine key factors related nursery pest management. Types of data collected included: key pest species; pest-plant relationships; grower action responses to pest problems; types and frequency of pesticide use. The second year, 1990-91, involved implementing IPM strategies such as: cultural methods; use of horticultural oils, soaps, and lower risk pesticides; and spot treatment applications to help maintain pest populations below economically damaging levels. Improvements in pest management included; reduced chemical applications, reduced associated environmental risks, and maintenance of aesthetic quality of plants.

Rose (Rosa spp.), especially R. hybrida, is one of the most popular ornamental plants in the world and the third largest cut flower crop in Taiwan. Rose mosaic disease (RMD), showing mosaic, line patterns and ringspots on leaves, is a common rose disease caused by the complex infection of various viruses. Due to pests and diseases, the rose planting area in Taiwan has been decreasing since 2008; however, no rose virus disease has been reported in the past five decades. In the spring of 2020, rose samples showing RMD-like symptoms were observed at an organic farm in Chiayi, central Taiwan. The virome in the farm was analyzed by RNA-seq. Rose genomic sequences were filtered from the obtained reads. The remaining reads were de novo assembled to generate 294 contigs, 50 of which were annotated as viral sequences corresponding to 10 viruses. Through reverse transcription-polymerase chain reaction validation, a total of seven viruses were detected, including six known rose viruses, namely apple mosaic virus, prunus necrotic ringspot virus, rose partitivirus, apple stem grooving virus, rose spring dwarf-associated virus and rose cryptic virus 1, and a novel ilarvirus. After completing the whole genome sequencing and sequence analysis, the unknown ilarvirus was demonstrated as a putative new species, tentatively named rose ilarvirus 2. This is the first report of the rose virus disease in Taiwan.

Introduction and objectives: Rose is one of the most harvested and demanded species as ornamental flower; its traditional propagation is limited due to the spread of pests and diseases; for that reason, in vitro culture has turned out to be an alternative to propagate healthy plants. However, microbial contamination and tissue oxidation are critical problems that can limit in vitro plant establishment. The aim of this research was to evaluate disinfection protocols and culture conditions for in vitro regeneration of Rosa chinensis with low contamination and oxidation percentages. M&M: The explants were washed with different disinfectant agents and seeded in a basal medium interacting with different factors such as activated charcoal (1 g/L) and temporary darkness (3 days). Results: protocol 2 presented the lowest percentage of bacterial (18.75 %) and fungal (12.5 %) contamination in the disinfection phase; while treatment T3 (activated charcoal 1 g/L + 3 days of darkness) obtained the best results in the introduction phase, and the explants presented the lowest phenolization level (0.88), favoring the induction of buds and callus in the explants, and reaching averages of 81.25 and 31.25 %, respectively.

The assortment of floral and ornamental plants is annually replenished with new varieties of perennial floral plants. The group of late summer and autumn flowering perennials is one of the most popular in landscaping. Korean chrysanthemum (Chrysanthemum сoreanum) is one of the most promising crops for landscaping settlements in the Republic of Belarus, therefore, breeders of the Central Botanical Garden of the National Academy of Sciences of Belarus began to work with this group of small-flowered chrysanthemums.The article describes the results of breeding work, the purpose of which was to create local highly decorative varieties for our climatic zone. The method of free cross-pollination and subsequent selection from the obtained hybrid seedlings of the most promising forms were used in the work. The most significant features in the selection were the following: flowering time, winter hardiness, resistance to diseases and pests, as well as good vegetative reproduction. As a result, 4 domestic varieties of Korean chrysanthemum have successfully passed state variety testing and have been registered in the National List since 2020. Descriptions of these new varieties, their biometric parameters, decorative parameters and flowering times are provided.

A tissue culture system was developed to clonally propagate a series of hybrid white oaks (Quercus L.) at the plant breeding program of the Urban Horticulture Institute (UHI), Cornell University. From 2014 through 2018, 34 genotypes and 1966 individual explants of UHI hybrid white oaks were trialed to determine their capacity to establish, multiply, and root in a tissue culture environment. UHI hybrid oak genotypes were selected based on their known tolerance to stresses common in the urban environment (drought, alkaline soils, pests, and diseases) and their ornamental qualities. Individual genotype was the single largest factor affecting successful establishment, multiplication, stabilization, and rooting of hybrid oaks in vitro. Thirteen clones of hybrid oaks were identified as having the capacity to stabilize and grow continuously in the multiplication phase. Multiplication efficiency rates were dependent on individual genotype. Stabilized genotypes showed the capacity to be re-established during successive years. The tissue culture process was simplified and refined to make the protocols less labor intensive for laboratory technicians using these methods. This study presents a preliminary and promising method for the clonal propagation of oak species and provides a path for cultivar development for plants belonging to the genus Quercus.

Nowadays, immediate environmental friendly solutions such as the use of biopesticides and other methods to control and manage pests are well needed. They are imperative due to the continuous accumulation of toxic residues from synthetic insecticides into the environment, the contamination of global agro-ecosystem and resistance of certain insects and pathogens. The global renewed interest of botanical pesticides does not leave aside Turkey. Thus, many environmental reports pointed out contaminations in different regions of Turkey by chemical pesticide residues, like lambda-cyhalothrin in some conventional grapes farming in the Aegean region. The use of botanical pesticides like Pyrethrin extracted from Pyrethrum’s flowers (Chrysanthemum cinerariifolium) is part of sustainable agriculture goals to reduce the incidence of pests and diseases without any alteration to the natural balance. The purpose of this review is to analyse and identify the possibilities of Pyrethrum production in Turkey. Various research works around the world were compiled and some key informants were correlated to existing researches in Turkey. Subsequently, it was found that the Black-Sea region of Turkey has great potential in the growing and industrial production of Pyrethrum by its weather patterns (temperatures, pluviometry and humidity) and soil characteristics. The region has a similar climate with the East-African high-lands well-known for Pyrethrum production. Thus, the country has shown great technological advances and the capacity to produce vegetative and disease-free clones for other ornamental plants by using tissue culture techniques. Therefore, the multiplication of high-quality vegetative clones of Chrysanthemum cinerariifolium and their maintenance can sustain commercial and long term production of Pyrethrum in Turkey.

The number of threats to the plants is constantly increasing. The harmful impact of pests and plant diseases costs billions of dollars to the global economics each year. Chemical protection of plants from diseases and insects became an urgent problem in crop production, forestry and parks. The study aimed to develop an effective mobile robot for treating trees and shrubs from insects and diseases by spraying with chemicals. The work used monographic and general scientific research methods. A review of existing designs and technologies, as well as an analysis of publications in leading scientific journals, led to the conclusion that there is no one generally accepted technology for remote diagnosis and spot spraying of single trees and shrubs. Most of the technical means used have significant technical and environmental limitations. Currently, there is no unambiguous decision about which machine and technology to choose for solving the problems of remote diagnostics and spot spraying of single plant objects with a height of 2 to 4 meters. Taking into account the identified requirements, a robotic platform was developed for diagnosing and spot spraying of ornamental and fruit trees and tall shrubs. The developed robot is equipped with the necessary set of equipment for moving around the territory and spraying objects, has an increased cross-country ability, works according to a given program, has a minimal environmental impact, and can record data for diagnosing problems on plants. The proposed universal robot can work in agricultural, forest and urban areas, in warehouses and production facilities.

Pure polyethylene (PE) is enriched with several additives to make it a smart application material in protected cultivation, as a cover material for either greenhouses or screenhouses. When this material completely or partially absorbs ultraviolet (UV) solar radiation, then it is called UV blocking material. The current work presents a review on the effects of the UV blocking covering materials on crop growth and development. Despite the passage of several years and the evolution of the design technology of plastic greenhouse covers, UV blocking materials have not ceased to be a rather interesting technique for the protection of several vegetable and ornamental species. Much of the research on UV blocking materials focuses on their indisputable effect on reducing the activity of pests and viral-related diseases, rather than on the effects on the crop physiology itself. In the present paper, representative studies dealing with the effect of the UV blocking materials on the agronomic factors of different crops are presented and discussed. The results reveal that UV blocking materials have mainly positive effects on the different plant physiological functions, such as photosynthesis and transpiration rate, and on growth characteristics, while they might have a negative effect on the production and content of secondary compounds, as anthocyanins and total phenolics.

Peat has good water retention properties, low mass, low pH and is free from diseases and pests. The water retention properties are particularly important for optimizing irrigation and thus water consumption in plant production. We investigated the water retention properties of unused and used peat substrate and various mixtures with additives, as well as the occurrence of water repellency, as this influences water absorption into the substrate. Unused peat substrate and different mixtures retained between 3.4 % and 18.4 % more water than the used substrate. The daily water losses are lower for the used substrates that initially contain lower water content at full saturation. At tensions between 10 and 33 kPa, the unused peat substrate contained between 25 % and 32 % water. The wilting point (WP) for unused peat substrate (tension between 300 and 1500 kPa) was between 15 and 18 %. Peat substrate has a wide interval of field capacity and the transition from the field capacity to wilting point is fast (change in water content between 7 % and 10 %). After drying, the water repellency of both unused and used peat substrates increased.</p>

Abstract Protection of greenhouse-grown horticultural crops, including ornamentals and vegetables, from damage caused by insect pests involves implementing strategies such as insecticidal and/or biological control. However, cultural control may also mitigate plant damage caused by insect pests, as well as plant diseases including fungi and bacteria. An important cultural control is sanitation. Herein, we review the use and potential impact of sanitation practices as a part of an integrated pest management program for greenhouse production. These include removing weeds from inside and around the greenhouse perimeter, disposing of plant and growing medium debris from inside the greenhouse, and managing algae within the greenhouse. Weeds serve as alternate hosts for insects, such as aphids (Aphididae), whiteflies (Aleyrodidae), and thrips (Thripidae), that can spread plant viruses among greenhouse-grown horticultural crops. Sanitation practices that may reduce problems with weeds include installing geotextile fabric barriers underneath benches and on walkways, hand removal, mowing around greenhouse perimeters, and/or applying herbicides. Plant and growing medium debris serve as sources of insect pests, such as whiteflies, thrips, and fungus gnats (Sciaridae). Therefore, removal of plant and growing medium debris from within greenhouses and/or placement into refuse containers with tight-sealing lids before disposal may reduce problems with insect pests. Algae provides a habitat for fungus gnats and shore flies (Ephydridae) to breed. Overwatering and overfertilizing plants contributes to algae growth. Applying disinfectants or algaecides may mitigate problems with algae accumulating in greenhouses. In addition to reducing insect pest problems, sanitation practices may help reduce inputs from insecticide applications.

The results of research of green areas in localities Malorechenskoye and Rybachye (South-Eastern Crimea) are presented. Large-scale landscaping of the studied territory was carried out in the 60-80-ies of the XX century. Modern structure of green spaces is typical for coastal settlements – basically, these are parks of recreational complexes, with high concentration of diversity of trees and shrubs species. A historical park (the oldest one) in the South-Eastern Crimea (late 50s – early 60s of the XIXth century) is also located in Malorechenskoye. The researches made taxonomic, botanical-geographical and biomorphological analysis of dendroflora. The frequency of occurrence of species, the condition of plants, as well as the degree of their drought and frost were assessed. The studied dendroflora includes 106 species belonging to 75 genera from 43 families. The species diversity of trees and shrubs in Rybachye is higher than in Malorechenskoye (89 and 67, respectively). At the same time, 13 species are widely distributed in both settlements, the most numerous of which is Cupressus sempervirens. It was revealed that species of the Mediterranean floristic region predominate (31.1 %), and representatives of native Crimean flora take a significant place (34.9 %). The leading position in the biomorphological structure of the dendroflora belongs to deciduous trees (25.5 %), followed by deciduous and evergreen deciduous shrubs (19.8 % each), and coniferous trees (17.0 %). The species diversity of deciduous shrubs and coniferous trees is significantly higher in Rybachye than in Malorechenskoye. Most plants are adapted to local climatic conditions: 57.5 % of species are not damaged by drought, the rest suffer from it in different degrees; 78.3% of species are frost-resistant, others are periodically damaged by low temperatures and need better protected from frost and cold winds planting sites. The absolute majority of species (95.3 %) are in good condition. Plants Aesculus hippocastanum, Buxus balearica, B. sempervirens, Euonimus japonica are more or less affected by pests and diseases. Special attention should be paid to the preserve the historical park in Malorechenskoye and to give it a protected status.

The comparative ease and speed of international trade and travel have enabled or enhanced the spread of pests around the globe. For example, trade in ornamental plants has bolstered the spread of alien Oomycetes such as pathogenic species of Phytophthora. To date, four Phytophthora species have been identified in Finland: P. cactorum on Fragaria x ananassa, Betula pendula and Rhododendron spp., P. plurivora on Rhododendron spp. and Syringa vulgaris, and P. pini and P. ramorum on Rhododendron spp. The ascomycete Colletotrichum acutatum, which was listed as a quarantine pathogen by the European Union until 2009, was introduced in 2000 and can survive in plant debris over two winters in Finland. Positive PCR results have also been obtained from bait plants grown in soil collected from locations where diseased Fragaria x ananassa plants had earlier been destroyed. In the mid-1990s, there was an epidemic of foliar rust caused by the Asian basidiomycete Melampsoridium hiratsukanum on Alnus glutinosa and A. incana. Recently, two ascomycetes that have been introduced are Dothistroma septosporum (responsible for red band needle blight on Pinus sylvestris) and Chalara fraxinea (causing ash decline on Fraxinus excelsior).;

Pyrus zangezura Maleev (Rosaceae) is a rare species representing the native vegetation of Armenia (Southern Transcaucasus). It was first described in 1936. P. zangezura has been cultivated at the Peter the Great Botanical Garden of the Komarov Botanical Institute (St. Petersburg, Russia) since 1949, where it has reached the height of 8,0 m. For many years, it was in its vegetative state. The first flowering was observed in 2016 (the plant entered the reproductive state). The first progeny from seed was obtained in April 2019. Fruit size was assessed for P. zangezura plants in the dynamics of their development. The studied plants of P. zangezura in the environments of St. Petersburg have demonstrated a high fruiting potential – on average, 109 flowers per 1 m of a shoot. Observations have shown that not all ovules in the opened flowers of P. zangezura are fertilized and produce fruits and seeds. A significant part of the opened flowers, a few days after the onset of flowering, dry up and fall off. On average, 7 fruits are set on 1 m of the shoot in P. zangezura. The reasons for the low flower setting may be variable: impaired pollination processes and insufficient fertility of pollen, underdevelopment of the flower morphological structures, or lack of pollinating insects due to adverse weather conditions. An X-ray analysis of the seeds from the harvests of 2016, 2017 and 2018 showed that the number of plump and fully developed seeds (grades IV and V) in fruits has been growing year by year. As an ornamental plant, P. zangezura may adorn any botanical garden, but it is also promising for urban landscaping, for example, in St. Petersburg. Even in the vegetative state, its elongated lanceolate glossy leaves make it appreciably different from the common P. communis L., and it is especially ornamental during flowering and fruiting. It is as winter-hardy as the common pear-tree, demonstrates resistance to diseases and pests, and may be of importance for breeding programs aimed at the development of resistant cultivars for the Northwest of Russia.

17 live plant collections numbering about 5 thousand species and varieties of different climatic zones were the basis for the introduction and breeding tests in the Stavropol Botanical Garden. The species and varieties of Daylily Hemerocallis×hybrida hort. were chosen as the parent material. The Нemerocallis (or Daylily) belongs to the Xanthorrhoeaceae Juss. family. Known for a long time as medical and ornamental plants, daylilies have attracted significant attention in recent years because of their longevity, xerophytism and tolerance to winter conditions, relative sample unpretentiousness. Since 2009, the breeding of daylilies has been in progress in the Stavropol Botanical Garden aimed at creating decorative varieties for the steppe zone that are resistant to unfavourable abiotic and biotic stressors. It was revealed that the promising hybrid progeny has diverse colours of the flower with corrugated edge and petals. The petal edges are folded at a 90º angle and bent back, forming a turban. Prolonged flowering for up to 30 days and more is ensured by numerous generative shoots and flowers on the flower spike (12 to 26). Hybrid progeny matches the height, flowers colour, decorative effect of leaves, resistance to external environmental factors, diseases and pests, of the assumed model and is recommended for further study and evaluation of decorative. The studied hybrids are valuable parent material for further breeding work and can be recommended for gardening.

Flowers are adorable creations of the god useful for all occasions from birth to death of human life. Thus, the tendency of people to accept flower on all occasion make it a great potential sector to contribute largely to the national GDP. The floriculture business is increasing 6-9% yearly over the last 20 years. About 20% cut flower, 60% ornamental plants, 90% seeds, and 20% as a whole floral product demands is fulfilled by imports with 12-15% increasing demand annually. Among them, only 14 % of farmers are contacted in extension and 31% received training regarding production, marketing promotion and linkage, entrepreneurship development, and leadership development. 80% share of floriculture export is occupied by propagation material, especially to India, and importing live plants and cut flowers majorly from India i.e., 38.40%. This is due to weak accessibility of information on technology and technical experts, low price export and high price import, weak export marketing management, promotion, and country singularized export. Policy for investment guarantee, import substitution, and export promotion; infrastructure development for wholesale markets, cold storage, refrigerated van, and collection center; package program for irrigation, greenhouse, transport, packaging, manpower development, and seeds; research and development for local spices, manpower development, production location, diseases, and pests, marking network, etc. are the essential need of floriculture sector development in Nepal.

Full textAbstract:
Spiraea japonica is an old-fashioned shrub widely grown in Italy in parks and gardens. In the summer of 2003, severe outbreaks of a previously unknown powdery mildew were observed in some parks and gardens in the city of Torino (northern Italy). Infected leaves became covered on both sides with a white mycelium. As the disease progressed, infected leaves turned reddish and eventually dropped prematurely. The presence of powdery mildew infections on leaves sometimes caused their distortion and growth reduction. Frequently, mycelium was observed also on the stem. Conidia were hyaline, ellipsoid, cylindrical, or dol iform, born in chains, measured 21.0 to 38.4 × 10.8 to 14.4 mm, and showed fibrosin bodies. Cleistothecia were not observed. The pathogen was identified as Oidium subgenus Fibroidium (1,2). Pathogenicity was confirmed by spraying leaves of healthy potted S. japonica plants with a conidial suspension (105 conidia per ml) prepared in sterile water from diseased leaves. Three plants were inoculated and three noninoculated plants served as control. The artificial inoculation was carried out twice. After artificial inoculation, plants were maintained in a growth chamber at 25°C. After 20 days, powdery mildew symptoms developed. Microsphaera alni and Podosphaera oxyacanthae were described as causal agents of powdery mildew on S. japonica in the United States (3), while Sphaerotheca spiraeae was considered the causal agent of a powdery mildew observed in Japan (4) and more recently in Poland.

Relevance and methodology. Lychnis coronaria is a perennial herbaceous plant with high decorative properties, with prolonged flowering in the second or third year of vegetation. The pubescent leaves form beautiful rosettes. The plant is undemanding to the growing conditions. The research material was the varietal population of Lychnis coronaria. The study was carried out in the open ground of the Moscow region (2014- 2021) on experimental plots of the flower crops sector of the FSBSI FSVC.Results. The most aligned form according to decorative features was identified – LC 1-21 with high seed productivity of inflorescences, decorative and winter hardiness. A variety testing and preliminary reproduction of a promising cultivar of Lychnis coronaria was carried out. This variety was transferred to the FSBI "State Export Commission" in 2021 under the name “Malinovy Rassvet”. Such signs as "plant height", "bush diameter", "number of ornamental shoots", "flower diameter" had a low or average variation value, which characterizes this sample as the most aligned. Thus, the cv. “Malinovy Rassvet” of Lychnis coronaria is recommended for cultivation and use for decorative purposes. The leaves and the bright color of the flowers provide a contrast to the perennial borders and flower beds. It looks good both in single and group plantings, as well as in cutting. It is grown as a short-lived perennial. The main advantages of the variety are the color fastness of flowers when burned out in the sun, resistance to diseases and pests, high seed productivity.
