OIDIUM OF GRAPES

The objective of the study is to analyze the literature on the prevalence and methods of combating oidium in Russia and the world. It is noted that, parasitizing on young shoots, the fungal disease causes significant damage to viticulture, leading to crop failure and reduced product quality. Under favorable conditions for the spread of the disease – high humidity and air temperature, in order to maintain high productivity of vineyards, it is necessary to use chemical plant protection products with the transition to biological control methods, regular monitoring to make a long-term forecast of the spread of infection using modern digital, automated technologies and UAVs. The forecast serves as a basis for planning the volume of work and determining the need for both preventive and active measures to combat the disease with biological and chemical fungicides with their alternation during the growing season to exclude the establishment of resistance. When making forecasts, it is necessary to accurately know the degree of development and prevalence of the disease in the surveyed area. It is concluded that the ability of grape varieties to be genetically resistant to the disease is a promising technique in the pursuit of environmentally friendly viticulture with reduced economic costs. In line with modern environmental and sanitary-hygienic requirements, modern agricultural technologies contribute to the preservation and restoration of the energy potential of the natural environment, reducing the socio-economic risks of production. This also creates attractive conditions for investment in a socially and economically important industry for Russia. The organization of protective measures is based on the generalization of extensive information on the phenology of plantings, the number and physiological state, the spread of weeds, the timeliness, quality and effectiveness of the treatments and agrotechnical measures carried out, and the characteristics of climatic conditions.
