The study revealed that dichlorvos 76% EC (0.076%), imidacloprid 17.8 SL (0.00712%) and dimethoate 30% EC (0.06%) were effective with the maximum mortality in thrips at 48 hours after treatment. Whereas, in whiteflies dimethoate 30% EC (0.06%) with 71.11 per cent mortality followed by imidacloprid 17.8 SL (0.00712%) 70.0 per cent mortality were observed. Thiamethoxam 25 WG (0.005%), imidacloprid 17.8 SL (0.00712%) and dimethoate 30% EC (0.06%) were effective against mealybugs.
