Tebuconazole and compositions of tebuconazole with prothioconazole and diphenoconazole are effective for controlling spike fusarium. \u0000Conclusions. The most reliable protection of crops from Fusarium infections is the formation of agrophytocenosis with a low level of infectious background due to the reduction in the rotation of the areas of donor crops Fusarium spp. Minimization of soil cultivation contributes to the spread of pathogens of Fusarium. The key elements for obtaining healthy sowing are the introduction of cultivar-resistant varieties and hybrids resistant to Fusarium spp. And the use of highly effective fungicides and their compositions, including succinate dehydrogenase inhibitors, with insecticides during the growing season.","PeriodicalId":238317,"journal":{"name":"Karantin i zahist roslin","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114196848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Informational and analytical. The collection of information was carried out in accessible specialized literature and the Internet. \u0000Results. The information about sucking pests of vegetable crops - thrips is given.  Thrips are known for a long time, they belong to wide polyphages, that is they harm a wide range of cultural and wild plants  (from 100 to 400 spesies). On an example of the most common of them — tobacco thrips (Thrips tabaci Lind.) there is given information about the morphology and biology of the pest, the methods of its spreading and harmfulness, as well as the information on the necessary phytosanitary measures for restriction its development and reduction of the harm. This most widespread and dangerous polyphage, due to its close connection with plants, where its entire life cycle develops - from eggs to imago, has inhabited almost all greenhouses. In the natural conditions of the southern region of Ukraine, the tobacco thrips were found on large areas of vegetable crops with the seedling method of their cultivation, mainly cucumbers, tomatoes, onions, cabbage, watermelons, and the like. It harms bulbs in vegetable stores, which leads to a deterioration in the quality of garden plants and gardening material. The reaction of the plant to the damage by the trips is desensitization, which is manifested in growth retardation, distortion and loss of turgor of damaged leaves, which later become yellow and dries. Imago winter, mostly females, in greenhouses - in different slits, and in open ground - in the upper layer of soil at a depth of 7-10 cm, under plant remains or in the rootstock of perennials or weeds. At temperatures below 0 ° С and in the absence of snow cover, insects die. The pest spreads at all stages of development - eggs, larvae, imago - with planting material of vegetable crops (with plants or in soil), transport, containers, workers' tools, their clothes or footwear. This also occurs when collecting, packing and selling contaminated products. This is especially true for cabbage, with which the thrips can get to the greenhouse or indoor plants. In the conditions of the steppe and forest-steppe zones of Ukraine, the tobacco thrips can develop in open soil at temperatures over 10 ° C during the growing season from the second decade of May to the end of September, causing significant damage to vegetable crops.

Carrying-out of a pest risk analysis (PRA) for Ukraine in relation to Cydia inopinata Heinrich (Manchurian moth) — pest of fruit and ornamental crops, according to the EPPO standard PM 5/3 (5) and improvement of methods for assessing the probability of acclimatization of adventive pest organisms beyond existing areas using modern computer software. \u0000Methods. Information and analytical, building electronic maps using GIS technologies. \u0000Results. There are cited information about the dangerous quarantine pest of fruit crops C. inopinata absent in Ukraine. The ways of possible penetration of the pest into Ukraine were shown, as well as the presence of host plants on the territory of the state are determined and the climatic conditions corresponding to the possibility of settlement and acclimatization are established. The overall pest spreading rate (increase of the infected area) is difficult to estimate. The possibility of natural distribution of the Cydia inopinata is moderately low, and by the anthropogenic way it is very high. Importation of a pest is possible with fruits that are infected with caterpillars of the Manchurian moth from countries of the pest areal. Plants — the owners of C. inopinata are found throughout Ukraine. They are grown for the production of fruits (on a commercial basis or in private gardens), for decorative purposes (in parks, gardens, in urban greening), found in nature or planted in forest belts. Areas with a high density of host plants are more favorable for the settlement of the pest than those with a low density. Due to the adaptation possibilities, the pest can increase the range of plants — hosts in Ukraine. The area of the Manchurian moth is located in several climatic zones: from the subtropical climate in southern China to the sharply continental in Transbaikalia. The compliance of the climate of the central part of the pest area with the climatic conditions of all regions of Ukraine will contribute to the acclimatization of the pest. The absence of extreme winter temperatures, which are characteristic of part of the range in Siberia and in the north of China, will contribute to an increase of the pest population and its harmfulness.

The differentiation of varieties of spring oats for resistance to loose smut was revealed. 58 varieties of spring oats with resistance to the pathogen of 9—6 points were detected. 22 varieties are selected, which combine resistance with high yields. 5 varieties have been created: Decameron, Darunok, Dietuchnui, Dioscurii and Denka, which are in the Register of plant varieties of Ukraine, and received the “The Certificate of registration of the sample of the gene pool of plants in Ukraine” on 5 lines of oat: 467-15, 445-1791, 399-38, 477-5 and 493-27, which can be used as donors of resistance to disease.","PeriodicalId":238317,"journal":{"name":"Karantin i zahist roslin","volume":"46 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124488395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
