RM Poul, NE Jayewar and BV Bhede
The field investigations were carried out to evaluate the efficacy of seven newer insecticide molecules during Kharif 2019-20. The results revealed that all the insecticidal treatments were significantly effective against thrips over untreated control. Emamectin benzoate 5 SG most effective against the fall armyworm, Spodoptera frugiperda which was at par with chlorantraniliprole 18.5 SC, flubendiamde 39.35 SC and thiamethoxam 12.5 + lambda cyhalothrin 9.5. While in case of earhead worm, Helicoverpa armigera lowest number of larvae recorded in the treated with chlorantraniliprole 18.5 SC followed by flubendiamde 39.35 SC and emamectin benzoate 5 SG. The significantly maximum grain and fodder yield was recorded in emamectin benzoate 5 SG which was followed by chlorantraniliprole 18.5 SC and flubendiamide 39.35 SC.
