Abstract

The dominant pests in the apple and plum cenoses are representatives of the tortrix family (Tortricidae) on the apple - the codling moth (Cydia pomonella L.), on the plum - the plum moth (Grapholitha funebrana Mats.), which develop in the region of southern Russia in three full generations. The loss of yield from the vital activity of these phytophages can reach 60-80%. It has been established that the inclusion of a 2-fold application of the insecticide Insegar, WDG in the apple and plum protection system allows preserving 98.9% of apple fruits and 94.6-99.2% of plum fruits. The stimulating effect of the use of insecticides of the juvenile group on the agrobiological indicators of the apple-tree variety Golden Reinders and the plum Kabardinskaya early was revealed, namely, the increase in the length of the one-year growth. It has been proven that the double application of Insegar, WDG in apple and plum plantations does not lead to violation of hygienic standards for the content of fenoxycarb in soil and fruits.

Highlights

In the structure of perennial plantations of the Krasnodar Territory, the main area is occupied by pome and stone fruit crops, of which 24 thousand hectares are apple orchards and 4.7 thousand hectares are plum plantings

Summary

Introduction

In the structure of perennial plantations of the Krasnodar Territory, the main area is occupied by pome and stone fruit crops, of which 24 thousand hectares are apple orchards and 4.7 thousand hectares are plum plantings. 4 insecticides based on the active ingredient fenoxycarb are registered in the Russian Federation on perennial crops: Insegar, WDG (LLC (Limited Liability Company) "Syngenta"), Akarb, WDG (LLC "Agroprogress Kemikals"), Fazis, WP WDG and Acarb, WDG (250 g / kg fenoxycarb) are approved for use on fruit crops by the "Directory of pesticides and agrochemicals approved for use on the territory of the Russian Federation" with a consumption rate of 0,6 kg/ha for apple trees, 0,4 kg/ha for plums, no more than three times per season
