Evaluation of insecticides against tobacco caterpillar, Spodoptera litura on cabbage during 2016

Abstract

The experiment was laid out at farmers field Kommanal, Shivamogga, under field condition in a Randomized Block Design (RBD) with three replications consisting of eight treatments. The overall mean of different insecticides from first and second spray indicated that chlorantraniliprole proved very effective in recording lowest larval population of 0.38 and 0.29 larva per plant being statistically on par with flubendiamide (0.47 and 0.36), emamectin benzoate (0.51 and 0.42), spinosad (0.60 and 0.47), indoxacarb(0.69 and 0.56) and dichlorvos (0.76 and 0.62). NSKE (0.84 and0.73) was least effective compared to other treatments. While untreated check registered highest number of larvae per plant (4.49 and 5.73).
