Abstract

The most effective insecticide against tomato fruit borer was indoxacarb 14.5% SC at 300 g a.i./ha. It reduced the number of larvae by 69.63 and 84.78% in the first and second sprayings, respectively. The next most effective insecticides were spinosad (73 g a.i./ha) and chlorantraniliprole (30 g a.i./ha). The plot treated with indoxacarb yielded 71.79% more than the control plot, followed by chlorantraniliprole (69.44%) and spinosad (63.53%).
