Evaluation of management techniques for the control of insect-pests of Basmati rice in Punjab

摘要

Integrated pest management techniques based on scientifically proven componentfor the control of stem borer and leaffolder were evaluated in large scale field trails at farmer's field in village Sudhar (Distt. Ludhiana). In rice crop, IPMmodel-I (Traps + chemical control) gave higher economic returns than IPM model-II (Traps + trichocards + chemical control). In both the models the incidence of leaf folder (0.12-0.38 %) and stem borer (0.30-1.22 %) was lower than farmer's practice 1.19 per cent leaffolder damage and 1.29-3.42 per cent stem borer damage. In Basmati rice, IPM model-II (Traps + trichocards + chemical control) gave higher economic returns than IPM model-I (Traps + chemical control). In both the models the incidence of leaffolder (0.38-0.53 %) and stem borer (1.52-4.02 %) was lower than farmer's practice 3.35 per cent leaffolder damage and 14.42-15.97 per cent stem borer damage. In both, rice and basmati rice IPM farmers get low pest incidence and higher economic returns.
