Fenoxycarb effect on quality, productive capacity and food safety of Kabardinskaya rannyaya cultivar of the plum

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”.

Assessment of the influence of a biorational insecticide of the juvenoid class on the state of fruit cenoses

“…The release time of fenoxycarb in apple samples is 12.2 ± 0.1 min; plum and soil samples -4.8 ± 0.1 min. All calculations were performed using the ClarityChrom program, the standard deviation for all samples was 3% [3,15].…”

“…The increasing impact of anthropogenic and abiotic factors on agricultural landscapes is a priority task. Since 2017, in the Kuban zone of the central subzone of the Krasnodar Territory, studies have begun to determine the effect of juvenoid class insecticides (active ingredient fenoxycarb) on apple and plum cenoses [3]. Currently, 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 (LLC "Himagromarketing.…”
