SUSTAINABLE INTEGRATED PEST MANAGEMENT (IPM) STRATEGIES FOR THE MANAGEMENT OF MAJOR SUCKING PESTS OF BOLLGARD IIBt COTTON

摘要

The field experiment was conducted for the management of major sucking pests of Bt cotton by adopting IPM strategies. The results revealed that the population of leaf hopper, whitefly, aphid and thrips were below economic threshold besides keeping/ augmenting their natural enemies compared to the nan IPM plots. The higher seed cotton yield was obtained from the IPM plots (1997 kg/ha) compared to the non IPM plots (1681 kg/ha) with higher benefit cost ratio (1:2.1).
