Three new combi products (Flubendamide 240 SC + thiaclorprid 240 SC, spinetoram 6% + methoxyfenizide 30% @ 400 ml/ha, indoxacarb 14.5 SC + novaluron 7.7% SC) with two different doses and one new molecule (flubendiamide 480 SC) in two doses, alongwith cartap hypochloride and untreated control were evaluated in this experiment against S. incertuals. Spinetoram 6% + methoxyfenizide 30% @ 400 ml/ha recorded 0.75, 0.85 and 0.80% dead heart and was significantly superior to all treatments and showed lowest white ear head (1.62, 1.77 and 1.69% WEH). Maximum net profit of Rs. 24,541/- was obtained with the application of spinetoram 6% + methoxyfenizide 30% @ 400 ml/ha but highest B:C ratio found in novaluron 5.25% SC + indoxacarb 4.5 SC @ 750 ml/ha having B:C ratio 3.02:1.
