Abstract

The efficacy of nine insecticides and an untreated control (two applications) tested against thrips, revealed that fipronil (0.01%) proved to be most effective, followed by clothianidin (0.01%). The next most effective insecticides were acetamiprid (0.004%) and thiamethoxam (0.025%). Thiacloprid (0.04%) and malathion (0.05%) ranked in middle order of efficacy whereas, emamectin benzoate (0.002%), chlorfenapyr (0.01%) and chlorantraniliprole (0.05%) were proved to be least effective against thrips. Natural enemies like Coccinelis beetle was safe with insecticidal sprays.
