Abstract

This article presents the results of a study of the biological efficacy of modern insecticides against a dangerous pest, woolly apple aphid, in intensive apple orchards in the Uychi and Yangikurgan districts of the Namangan region. The experiments compared the efficacy of Nurell Extra 55% emc, Twingo 20% sus.c., Protect 5% emc, and Vinfos 75% emc. The results showed that Vinfos 75% emc, when applied at a rate of 0.5 l/ha, demonstrated the highest biological efficacy (93.3%) on the 14th day after treatment.
