Abstract

In the region of Krasnodar Territory, Cydia pomonella L. belongs to the dominant pests of the apple tree, against which 8-10 treatments with insecticides are carried out during the growing season. In world practice, pheromones Shin-Etsu® MD CTT, D and BRIZ® are used in apple agrocenoses for the control of C. pomonella. abstention or reduction of insecticidal treatments leads to a decrease in the pesticide load on the agrocenosis of the garden by a factor of two or more. The objective of our research was to determine the biological pheromones effectiveness in controlling C. pomonella quantity. The test was carried out in two horticultural zones of the Krasnodar Territory, in areas with different numbers of phytophage. The experiment as a result, it was found that in the experimental plots the percentage of damaged fruits in the drop was 1.3-1.5%. Fruit damage wasn’t observed in a removable crop, which corresponds to the results of the standard version, with the use of insecticidal treatments. It was found that the pheromones usage in the Black Sea horticultural zone of the Krasnodar Territory is economically feasible. Сost reduction for the purchase of insecticides amounted to 9089.2 rub/ha, a decrease in pesticide load by 70%.

Highlights

The protecting system apple trees from diseases and pests is based on the use of chemical pesticides of the second or third hazard classes, while every year there is an increase in the frequency of treatments during one growing season to 20 or more

Summary

Introduction

Need arises to switch to new strategies for protection against lepidoptera pests, in particular, against Cydia pomonella, in fruit plantations, in recent years. This concept should primarily be based on phytosanitary optimization of agroecosystems, expanding the list of plant protection products. Cydia pomonella is one of the main destructive species in apple plantations of the Krasnodar Territory. Specifics of pheromones are - effective control of the phytophage population at an economically imperceptible level, selectivity of action, absence of toxicity for mammals and entomophages, as well as high efficiency with minimal amounts and rapid degradation in the environment [2,3,4,5]
