ABSTRACT
Performance of different biorationals were studied under field condition for the management of gram pod borer, Helicoverpa armigera (Hubner) on chickpea at the Agricultural Research Station, Gulbarga, Karnataka, for three years. Azadirachtin 3% WSP @ 200 g/ha sequential sprayed plot recorded average larval population of 0.30 and 0.22 per five plants at five days after first and second sprays, respectively with 5.45 per cent pod damage and 1852 kg/ha grain yield which was statistically at par with sequential spray of profenophos 50 EC @ 500 g.a.i./ha followed by Chlorantranilliprole 18.5 SC @ 18 g.a.i./ha that recorded average larval population of 0.23 and 0.12 per five plants at five days after first and second sprays, respectively with 4.53 per cent pod damage and 1920 kg/ha grain yield. Parasitoids (Campoletis chlorideae) and tachnid fly (Carcelia illota) activity did not hindered in Azadirachtin 3% WSP, Neem soap and HaNPV treated plots. The treatment benefit was also in the same trend i.e., the difference between T8 (` 21616) and T2 (20594) was very narrow of ` 1022 with a benefit:cost ratio of ` 3.74 and 3.56 in T8 and T2 respectively for every rupee investment in the production of crop. Average per cent parasitization of H. armigera by C. chlorideae was 11.89 (in Neem soap), 11.68 (in HaNPV), 11.67 (in Azadirechtin 3%) and 13.23 (in untreated check) and were at par with each other and significantly superior over Chlorantranilliprole (5.50 %). Significantly lowest larval parasitization was recorded in profenophos treated plot (3.05%). Similar is the activity response by tachnid fly.
