Avoidable yield loss in greengram due to major insect pests through insecticide spray schedules under field conditions

M Sesha MahaLakshmi, M Sreekanth and M Adinarayana

A field experiment was conducted at RARS, Lam Farm, Guntur to evaluate the spray schedules of insecticides in reducing the yield losses in greengram for two consecutive seasons i.e. during Rabi 2013-14 and 2014-15. Adoption of seed treatment with imidacloprid 600 FS @ 5.0 g/kg seed followed by one spray with either thaimethoxam 25 WG @ 0.2 g/lt or acetameprid 20 SP @ 0.2 g/lt at 25 DAS and flubendiamide 39.35 % SC @ 0.2 g/lt or indoxacarb 14.5 % SC @ 1.0 ml/lt at 40 DAS gave higher seed yield due to less incidence of YMV coupled with low pod damage due to spotted pod borer in greengram. The avoidable yield loss was highest with flubendiamide 39.35 % SC @ 0.2 g/lt followed by indoxacarb 14.5 % SC @ 1.0 ml/lt and spinosad 45 SC @ 0.3 ml/lt when sprayed at 40 DAS thus helps in attaining high seed yield in greengram.
