Field experiments were carried out at the Vegetable Research Farm, College of Agriculture, Central Agricultural University, Imphal, Manipur for two consecutive Rabi seasons, 2020-21 and 2021-22 to determine the efficacy of biorational insecticides and chlorantraniliprole against Helicoperva armigera on tomato under Manipur condition. Among the nine insecticides tested, chlorantraniliprole 18.5 SC @ 150 ml/ha was found most effective against H. armigera followed by green lipel (Bacillus thuringiensis var. kurstaki) @ 2500 ml/ha and green focus (botanical extract of Derris indica) @ 1000 ml/ha. Cow urine + Artimisia nilagirica proved to be the least effective followed by green pacer (Metarrhizium anisopliae). Among biorational insecticides tested, maximum fruit yield (19.12 t/ha) was harvested from the plots treated with green lipel which did not differ significantly from that of green focus (19.03 t/ha) treated plots.
