Eight insecticides were evaluated against aphid, Brevicoryne brassicae in cauliflower and found that all insecticidal treatments were significantly superior over untreated control, in reducing the population of aphid however; significant differences existed among the various treatments. Flubendiamide20% WG @ 0.4gm/l was found most effective followed by lufenuron 5.4% EC @ 1ml/l and others showed intermediated effects in reduction of aphid population.
