Abstract

Field plot trials were conducted for two consecutive seasons during rabi 2000–01 and 2001–02 to evaluate some newer insecticidal formulations for their efficacy against chickpea pod borer, Helicoverpa armigera (Hubner). Two sprays were given per treatment at 15 days interval, commencing from 50% flowering. The results revealed that, the treatments viz., cypermethrin 5 + acephate 45DF @425 g ai/ha, acephate 75DF 600 g ai/ha and cypermethrin 5 + acephate 45DF @400 g ai/ha with 14.3, 16.6 and 16.8 per cent pod damage were equally effective and gave 59.8, 53.4 and 52.8 per cent protection to the crop against pod borer. The latter two treatments were at par with cypermethrin 5DF @ 60 g ai/ha, acephate 75DF @ 575 g ai/ha and cypermethrin 5DF @ 50 g ai/ha with 17.0, 17.1 and 19.3 per cent damage respectively. The highest seed yield of 10.0 q/ha was harnessed by cypermethrin 5 + acephate 45DF @ 425 g ai/ha with 88.7 per cent increased yield over untreated control. The next best treatments which recorded higher seed yield included cypermethrin 5 + acephate 45DF@ 400 g ai/ha (9.0 q/ha), cypermethrin 5DF@ 60 g ai/ha (9.0 q/ha), cypermethrin 5 + acephate 45DF@ 375 g ai/ha (8.6 q/ha), acephate 75 DF @ 600 gai/ha (8.4q/ha), cypermethrin 5 DF@ 50 g ai/ha (8.3 q/ha) and chlorpyriphos 20 EC@ 250 g ai/ha (8.1 q/ha) with 69.8, 69.8, 62.3, 58.5, 56.6 and 52.8 per cent increased yield over untreated control
