OPTIMIZATION OF PROTECTION OF APPLE FROM SHEETS IN THE CONDITIONS OF A COLLECTION KENNEL
The data on the study of the leaf tortix community under the conditions of agrocenosis of the fruit nursery according to the generally accepted method using the visual accounting method are presented. Phenological observations of the life cycle of phytophages have been made. Monitoring the phytosanitary situation in the collection nursery showed that leaf worms are the dominant pests. The dynamics of their numbers varied throughout the season. The highest activity was observed in the second decade of April and the first decade of June. In the 3rd decade of April, the number of leaf worms exceeded the economic threshold for harmfulness (EPV - 5-8 caterpillars per 100 rosettes), therefore, insecticidal protection of the apple tree was carried out with the preparations Proteus, MD, Calypso, KS. Treatment with drugs reliably protected trees from the phytophage. The highest biological effectiveness was obtained with the use of the Proteus insecticide - 91%.
