Abstract

The insecticide, IMIDACLOPRID 17.8% SL was evaluated during rabi and in summer season of 2011 and 2012 against chilli thrips at Agricultural Research Station, Hanumanamatti. The test chemical, IMIDACLOPRID 17.8% SL has been found significantly effective for the management of chilli thrips at an appropriate dose of 50 g ai. per ha or 250 ml of formulated product per ha. This treatment recorded 25.07 per cent increase in the green chilli yield with a reduction of 70.47 per cent thrips damage over the untreated control. Management of chilli thrips with this insecticide has recorded significantly lower insect damage and highest grain yield. Hence, the IMIDACLOPRID 17.8% SL may be used for the management of chilli thrips at a dose of 250 ml of formulated product per ha.
