Performance of Integrated Pest Management Practices in Production of Bt Cotton in Karimnagar District of Andhra Pradesh - A Case Study

摘要

Integrated Pest Management in cotton production was demonstrated under Front Line Demonstration (FLD) in two villages in Karimnagar district of Andhra Pradesh during 2008-09 to 2010-11. The results revealed that IPM practices were superior in controlling aphids, mealy bug and Spodoptera as the incidence of these pests was significantly lower in the production of cotton. The activity of beneficial insects also improved in IPM fields when compared with non IPM fields. Seed cotton yield obtained was 16.6% higher in IPM fields than non IPM fields. Higher net returns (? 54217/ha) and B:C ratio 2.69 registered in IPM fields compared to non IPM fields (? 40488/ha and 2.15, respectively).
