摘要

A field experiment was carried out at the Agricultural College Farm, Naira during rabi, 2019-20 on management of insect pests of sweet corn with special emphasis on fall army worm Spodoptera frugiperda (J E Smith). The results revealed that emamectinbenzoate 5SG @0.4 g I1 (83.19% reduction in larval incidence) followed by spinosad 45SC @ 0.3 ml I', chlorantraniliprole 0.4G @ 10 kg ha 1 and chlorantraniliprole 9.3%+ lambda cyhalothrin 4.6% @ 0.5 ml 1' were significantly superior (with 80.49, 77.02 and 74.67% reduction in larval incidence, respectively). The treatments with cyantraniliprole 19.8% + thiamethoxam 19.8%FS @ 6 ml kg ', lambda cyhalothrin 5EC @ 2ml l'and fipronil 0.3G @ 12 kg ha 1 were the less effective ones. Emamectin benzoate 5SG gavemaximum yield of 39,716 kg ha1 with ICB ratio of 1:22.57.
