Field efficacy of tetraniliprole 200 SC, a new diamide insecticide molecule against common cutworm, Spodoptera litura in soybean

Abstract

An experiment was conducted during Kharif 2013 and 2014 to find out field efficacy of newer diamide molecule against Spodoptera litura in soybean. Results revealed that the tetraniliprole @ 50 g a.i./ha or 60 g a.i./ha was the most effective dose followed by tetraniliprole @ 40 g a.i./ha or chloranthraniliprole 18.5 SC @ 30 g a.i./ha, which was significantly superior to triazophos 40 EC @ 250 g a.i./ha and untreated control. The pooled mean data of both the years on seed yield also showed similar results with an incremental yield of 11.2 and 13.8 q/ha for tetraniliprole @ 50 g a.i./ha and 60 g a.i./ ha, respectively over untreated control followed by chlorantraniliprole @ 30 g a.i./ha, tetraniliprole @ 40 g a.i./ha and triazophos @ 250 g a.i./ha with a mean seed yield of 11.5 to 18.4 q/ha and an incremental yield of 2.5 to 9.4 q/ha over untreated control. Tetraniliprole at higher doses did not show any phytotoxicity or adverse effect on natural enemies. So, this diamide molecule with a unique mode of action is effective against major insect pests of soybean which can be newer molecules for integrated resistance management programmes.
