Monitoring of the phytosanitary condition of grape plantations in the South of Ukraine in 2022—2023

Abstract

Goal. Comprehensive study of pathogens of new diseases and pests, bioecological features of their development, trophic and ecological relationships in modern conditions of vineyards cultivation, taking into account pesticide load and climatic conditions, in order to develop forecasts of the development of major diseases and pests and optimize the technology of vineyard protection.
 Methods. Monitoring studies of vineyard growing conditions in different agroecological zones of Ukraine. The research was conducted in the farms of Odesa region. The objects of monitoring are grape plantations of different planting periods and varietal assortment.
 Results. The phytosanitary monitoring revealed the dynamics of the bunch borer population development. The species composition and dynamics of the number of phyto- and entomophages were determined in the grape plantations of the South of Ukraine. The dynamics of the number of phytophagous mites on grape plantations of Odesa region was studied. It was found that all the studied grape varieties are infested with mites to varying degrees. The most susceptible to mites are varieties of medium or late ripening.
 Conclusions. The study of fungal diseases proved that these diseases are widespread in the grape plantations of the Northern Black Sea region, and their development depends on weather conditions during the growing season, age of plantations and biological characteristics of the variety.
