Purpose - to establish the prevalence rhizomania, Root rot and cercospora in Ukraine and develop methods for evaluating the stability of sugar beet to rhizomania and rot roots. Methods - Laboratory and field vegetation experiments. Distribution rhizomania to new territories and defeat cercospora root rot and creates a complex situation in sugar beet growing areas and requires the development of methods of monitoring. The study revealed a significant increase in the concentration of virus Beet necrotic yellowing of veins (BNYVV) in samples of sugar beet roots compared to previous years. However, visual symptoms in positive samples were pronounced. Based on the available information designed schematic map rhizomania spread in Ukraine. The study of roots to rot resistance showed that, depending on the year, from 30% to 70% of sugar beet unsuitable for long-term storage. Analysis of stability in terms of hybrids showed that among new domestic hybrids rot-resistant occur - Mace, Constant, quart, etc. Unification. Route survey found wide spread of crops cercospora leaf spot across the left-bank Ukraine forest, which can damage up to 70% of sown areas of culture and lead to significant loss of sugar beet harvest. A significant effect of intraspecific component type C. beticola on cercospora harmfulness. Assessment of the stability of sugar beet breeding materials on artificial infectious background brown rot pathogen Rhizoctonia solani root crops in the affected areas BNYVV showed a close correlation dependence (0.91) rhizomania between development and root rot (R. solani). This method of estimating the resistance breeding materials for root crops rot on infectious background rhizomania can be used to create raw materials sugar and fodder beet.5481 Product Description popup.authors Білоус Н.В Васільєва Н.О.
