Abstract

Field experiments were carried out to evaluate the performance of four IPM modules against leaf miner and diseases like root rot/wilt and Ascochyta blight in Kullu valley of Himachal Pradesh during Rabi 2010-11 and 2011-12. The findings of two years experiments revealed that the IPM module (M3) consisting of seed treatment by seed soaking in streptocycline @ 200 ppm followed by seed treatment with carbendazim (Bavistin 50 WP) @ 2.5g/Kg seed succeeded by two foliar sprays with a mixture of lambda-cyhalothrin 5EC @ 0.8ml/L(0.04%) and carbendazim @ 0.1% (Bavistin 50 WP) at the 50% flowering of the crop (3.5 months of sowing, 3rd week of March) and by the 2nd spray of mixture of acetamiprid @ 0.005% (Polar 25 SP) and triademefon @ 0.05% (Bayleton 2%) after 15 days of the first spray, was found to be most effective in minimizing the leaf infestation by leaf miner and root rot/wilt incidence with 85.1% and 98.2% reduction over control, respectively. This module was also found to be the most economic resulting in highest mean marketable pod yield (138.6 q/ha) during the two years and maximum net returns of ` 21.7 per rupee spent. However, for the control of Ascochyta blight, module M1 was found to be the most effective in minimizing the disease incidence with 68.8% reduction over the control.
