Effectiveness of bio-rationales and newer pesticides against damage due to yellow mite, Polyphagotarsonemus latus (Banks) on capsicum (Capsicum annum L.) under shade net house during summer

Abstract

Field experiment was conducted under shade net house at Hi-Tech Horticulture farm, Rajasthan Agricultural Research Institute (Sri Karan Narendra Agriculture University, Jobner) Durgapura, Jaipur, (Rajasthan) to investigate the effectiveness of eleven bio-rationale and newer pesticides against yellow mite, Polyphagotarsonemus latus (Banks) during summer 2014 and 2015 on capsicum (Capsicum annum L). The results revealed that during 2014 and 2015 all the treatments proved significantly superior in reducing the downward leaf curling in comparison to the control at 7,11 and 13 week after transplanting (WAT). The minimum leaf curling (5.84%) was recorded in the treatment of spiromesifen 22.9 SC at 0.0229 per cent which was significantly superior followed by propargite 57 EC at 0.114 per cent (7.50%) at 7 WAT. At 11 WAT, minimum leaf curling (4.17%) was recorded in the treatment of spiromesifen 22.9 SC at 0.0229 per cent which was significantly superior. The minimum leaf curling (5%) was recorded in the treatment of spiromesifen 22.9 SC at 0.0029 per cent which was significantly superior followed by propargite (6.75%) at 13 WAT. The overall effect indicated that the minimum leaf curling (4.45%) was recorded in the treatment of spiromesifen 22.9 SC at 0.0029 per cent followed by propargite 57 EC at 0.114 (5.84%) and emamectin benzoate 5 SG at 0.002% (7.23%). Thus spiromesifen 22.9 SC @ 1 ml/l could be suggested to the farmers for the management of yellow mite on capsicum under shade net house conditions during summer for off season production
