Efficacy of cyantraniliprole and chlorantraniliprole in control of oriental fruit moth (Cydia molesta Busck) in peach and nectarine orchards

Abstract

Using standard EPPO method, field trials were conducted in 2013, in order to investigate the efficacy of diamide insecticides, cyantraniliprole and chlorantraniliprole, in oriental fruit moth (Cydia molesta) control. The results of the field trials at the localities of Radmilovac and Vinča indicated high efficacy of cyantraniliprole (0.6 l/ha of preparation containing 100 g/l a.i.) and chlorantraniliprole (0,2 l/ha of preparation containing 200 g/l a.i.) from 94.5 - 98.7% in the control of C. molesta in peach and nectarine orchards. Applied ina lower amount (0.5 l/ha of preparation containing 100g/l a.i.) cyantraniliprole exhibits a statistically significant lower efficacy (92.0% - 94.1%) inboth localities, but this compound was more efficient at the locality of Vinča where the intensity of infestation in untreated plot was low.

Tokom 2013. godine ispitana je efikasnost insekticidnih preparata, na bazi cijantraniliprola i hlorantraniliprola (hemijska grupa diamidi) u suzbijanju breskvinog smotavca (Cydia molesta). Ispitivanja su izvedena u skladu sa standardnom EPPO metodom, u poljskim uslovima (lokaliteti Radmilovac i Vinča), u zasadima breskve i nektarine. Ostvareni rezultati ispitivanog preparata Exirel® (100 g/l cijantraniliprola), koji je primenjen u količini 0,5 i 0,6 l/ha, i standardni preparat Coragen 20 SC (200 g/l hlorantraniliprola) primenjen u količini 0,2 l/ha, ukazuju na zadovoljavajuću efikasnost (92,0 - 98,7%) u suzbijanju C. molesta. Primenjen u količini 0,5 l/ha ispitivani preparat je ispoljio statistički značajno nižu efikasnost (92,0% - 94,1%) za C. molesta u odnosu na efikasnost istog preparata ostvarenu primenom više količine (0,6 l/ha) i standarda, nezavisno od lokaliteta i vrste voća, što svakako treba imati u vidu pri izboru količine preparata za praktičnu primenu.
