Abstract

Rapeseed and mustard is the same group of oilseed crops (Brassica sp.) as well as a significant source of edible oil in Pakistan. The cabbage aphid, Brevicoryne brassicae is considered a major insect pest of oilseed rape, Brassica napus L. and causes significant yield loss. An experiment was conducted in a completely randomized design (CRD) consisting of four insecticidal treatments i.e. Confidor 200 SL (imidacloprid), Mospilan 20 SP (acetamiprid), Arrivo (cypermethrin), Triazophos 40 EC (triazophos) at low to high concentrations along with control treatment to estimate the efficacy of canola leaves against aphid population. Among all insecticide applications of cypermethrin and acetamiprid were found highly effective applied at higher concentrations throughout the experiment as compared to imidacloprid and triazophos, indicating consistent mortality at high and medium concentrations. Taking together, insecticides cypermethrin and acetamiprid were recommended to control aphid infestation based on their residual activity, yield response, and rate of marginal return. This study gives directions to control aphid infestation on a quick basis at a larger scale.
