Evaluation of new combi-molecules against insect pests of cotton

Abstract

The field experiments were conducted to evaluate the efficacy of new molecules in combination and alone against insect pests of cotton (sucking and bollworms) at Agricultural Research Station-Banswara (Rajasthan) during kharif -2016 and 2017. The trial was laid out in a randomized block design (RBD) with eleven treatments including untreated check, each replicated thrice. The results revealed that both the doses of sulfoxaflor 30% WG i.e. 437.5 and 375 ml ha-1 were found very effective against jassids with highest percent control. Whereas, pyriproxyfen 5% EC @750 ml ha-1 and pyriproxyfen 5% EC + fenpropathrin 15% EC @ 750 ml ha-1 were found more effective against whiteflies and also gave highest seed cotton yield.
