Abstract

Plum moth Grapholita funebrana Tr. is a dominating pest in entomological complex of plum production in the south of Russia. The yield`s loss caused by it can reach 60-70 %. In the modern plant protection systems Insegar, VDG (250 g/kg fenoxycarb) is most commonly used for control of the pest`s number. Its use helps to save up to 98.5-99.8 % of the fruit. The aim of the research was to study fenoxycarb`s effect on quality, productive capacity and food safety of Kabardinskaya rannyaya cultivar of the plum. It was found that double use of the insecticide doesn`t lead to significant difference in the content of organic acids and dry substances. However, it encourages the increase of the leaf`s surface by 4-10 sm² and annual additional growth of the plant by 6-52 sm in comparison to the control. It was established that fenoxycarb is completely decomposed at the end of the “Waiting period”.
