M. Roopa,CT Ashok kumar

Field experiment was conducted at the Gandhi Krishi Vignana Kendra (GKVK), University of Agricultural Sciences, Bengaluru, Karnataka, India during 2012-13 to test the bio-efficacy of new insecticide molecules against capsicum fruit borer, Helicoverpa armigera (Hubner). The results indicated that among different chemicals Spinosad 45 SC @ 0.01% emerged as the best treatment which recorded highest per cent reduction of 76.53 with a highest yield of 30050 kg/ ha. However, standard check Quinolphos 25% EC @ 0.05% (16300 kg/ha) was least effective in reducing the incidence of fruit borers.
