N. Manu, R.H. Patil, R.A. Balikai

Abstract


A field experiment was conducted during kharif, 2011 at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad on management of leaf eating caterpillars by newer insecticides, biopesticides and poison baits in soybean. Among the new molecules flubendiamide 480 SC @ 0.2 ml/l was found significantly superior in reducing the leaf eating caterpillar population and recorded highest seed yield (23.95 q/ha) followed by indoxacarb 14.5 SC (22.99 q/ha) and lambda cyhalothrin 5 EC (22.87 q/ha) as compared to other treatments including untreated check. However, among the biopesticide Nomurea rileyi @ 2 g/l was found superior over other biopesticides and poison baits except monocrotophos bait in bioefficacy. The highest B:C ratio was recorded in lambda cyhalothrin 5 EC @ 0.5 ml/l followed by indoxacarb 14.5 SC @ 0.5 ml/l, emamectin benzoate 5 SG @ 0.2 g/l and fluebendiamide 480 SC @ 0.2 ml/l.
