Abstract

Spray of cartap hydrochloride 75 SG @ 375g a.i./ha was most effective in minimizing the leaf damage up to (0.48%) and was at par with higher dose of cartap hydrochloride 75 SG @750g a.i./ha (0.60% damage) and fipronil 5 SC @250 ml/ha (0.69% damage). The remaining treatments, cartap hydrochloride 50 SP @500 g a.i./ha (1.08%), lambda cyhalothrin 2.5 EC @12.5 ml/ha (1.29%) and cartap hydrochloride 75 SG @281.5 g a.i./ha (1.03%) were found effective and significantly superior over untreated control.
