Abstract:
A field experiment was conducted during Kharif, 2018, to evaluate the bio-efficacy of conventional and new insecticides, which were cost-effective and ecologically feasible against the management of sorghum grain midge, C. sorghicola. During 15 Days after Spraying (DAS), a lower population (3.45 midges/ear head) was observed in lambda cyhalothrin over other molecules. Among the insecticide tested, the maximum per cent reduction of sorghum grain midge population (86.23%) was recorded in lambda cyhalothrin, followed by carbosulfan and fipronil, which recorded 76.51 and 71.74%, the lowest midge population, respectively, over control. Among the treatments, significantly higher grain yield was recorded in lambda cyhalothrin treated plots (22.89 q ha-1) with a 126.73 per cent increase over control. Similarly, higher biomass yield was recorded in lambda cyhalothrin of 72.82 q ha-1 with a 13.57 per cent increase over control.
