Abstract

The efficacy of seven insecticides was evaluated against major insect pests on long-duration pigeonpea crop. The results showed that Thiamethoxam 25 WG was the most effective against tur pod fly with the lowest maggot population, pod damage (23.33%), and grain damage (11.94%). Flubendiamide 480 SC resulted in the lowest larval population of gram pod borer, with the least pod and grain damage (0.67% and 0.21%, respectively). Thiamethoxam 25 WG also recorded the lowest bug population, pod damage, and grain damage in the case of tur pod bugs. The highest grain yield (1065.63 kg/ha) was achieved with Thiamethoxam 25 WG, followed by Flubendiamide 480 SC (1038.67 kg/ha). Thiamethoxam 25 WG also had the highest incremental cost-benefit ratio (1:7.04), followed by Flubendiamide 480 SC (1:5.06). Based on these results, Thiamethoxam 25 WG and Flubendiamide 480 SC can be recommended for controlling the key insect pests of pigeonpea in Eastern Plain Zone of Uttar Pradesh.
