Comparative performance of chemical insecticides, Neem derivatives and microbial insecticides against insect pests of pigeonpea

Abstract

Among several chemical insecticides, Neem derivatives and microbial insecticides tested for their performance against major insect pests of pigeonpea at pod initiation stage, monocrotophos 36 SL (0.04%) sprayed thrice at 12 days interval gave highest protection and yielded maximum grain (1410 kg/ha) followed by Nimbecidine (0.3%) (1090 kg/ha). Minimum yield (590 kg/ha) was obtained from the plot sprayed with endosulfan 35% EC (0.07%).
