Abstract

The present experiments were conducted to evaluate different group of insecticide molecules as foliar application for their bio-efficacy against major sucking pests of Bt-Cotton crop at JNKVV, Zonal Agricultural Research Station Chandangaon Chhindwara during Kharif-2017 & Kharif-2018 with seven treatments and three replications. Over all two spray were carried out during both years and thus the data obtained revealed that the insecticide molecule Flonicamid 50 % WG@ 150 g/ha was found best for managing the major sucking pest viz.
