Efficacy of various insecticides against Helicoverpa armigera (hubner) infesting greengram

An experiment conducted to determine efficacy of nine insecticidal treatments against Helicoverpa armigera (Hubner) infesting greengram revealed that the treatments with indoxacarb 0.0075 per cent, spinosad 0.009 per cent, cypermethrin 0.009 per cent and profenophos 0.05 per cent were most effective for control of gram pod borer. Among the insecticidal treatments, minimum pod damage (9.58%) and the highest seed yield of greengram (1516 kg/ha) were obtained due to the treatment with indoxacarb 0.0075 per cent, which was at par with spinosad 0.009 per cent (1467 kg/ha), cypermethrin 0.009 per cent (1420 kg/ha) and profenophos 0.05 per cent (1385 kg/ha).
