During 2008-09, six bio-pesticides were evaluated, under field conditions, for their efficacy against major defoliators and capitulum borer, Helicoverpa armigera Hub. infesting sunflower, at the Zonal Agricultural Research Station, UAS, Bangalore. All the six bio-pesticides viz., Spodoptera NPV @ 2×108 POB/ml, HelicoverpaNPV @ 2×108 POB/ml, Pongamia Seed Kernel Extract @ 5%, Neem gold 0.03EC(300ppm)(0.5%), Neem Seed Kernel Extract @ 5 % and Prosopan @ 10ml/L. were on par with the insecticidal checks (endosulphan 35 EC @ 0.07% andprofenophos 50EC @ 0.05 %) and they were found to be significantly superior than untreated check in the suppression of defoliators, 50 days after sowing. Neem seed kernal extract, (5%), prosopan (10 ml/lit) and both the insecticides were significantly superior than the other treatments, at one day after the second spray (i.e., @ 90 DAS) for H.armigera supression. © JBiopest.
