Evaluation different pest management components against major pests of rabi sorghum

Abstract

The field experiment was conducted during rabi 2018-2019 at Sorghum Improvement project, MPKV, Rahuri to asses different pest management components against major pests of rabi sorghum. Maximum plant population per plot was observed in plots treated with seed treatment with Imidacloprid 70 WS @ 3 g/kg of seed. The lowest per cent of dead hearts caused due to shoot fly (11.97%) were recorded in T2 where the plots treated with seed treatment with imidacloprid 70 WS @ 3 g/kg. The lowest per cent of dead hearts caused due to stem borer (0.47%) were recorded in treatment of whorl application of Carbofuran 3G @ 8 kg/ha at 35 DAE i.e., T2. The least number of aphids were recorded in the treatment, T6: dimethoate 30% EC @ 1 ml/liter (1.48 aphid/cm2/leaf). Effectiveness of various pest management components on the grain and fodder yield of sorghum indicated that, significantly highest grain and fodder yield (36.20 and 63.00 q/ha, respectively) was obtained from plot treated with imidacloprid 70 WS @ 3 g/kg of seed.
