Efficacy of Insecticide Modules Against Thrips and Mites in Chilli

Experiments conducted during 2016-17 and 2017-18 on chilli var. Tejaswini evaluated the efficacy of pest management modules at the Vegetable Research Station, Sri Konda Laxman Telangana State Horticultural University, Hyderabad. Biointensive, integrated and chemical modules were evaluated against thrips Scirtothrips dorsalis Hood and mite Polyphagotarsonemus latus Banks. Integrated module (seedling dip with imidacloprid 17.8%SL @ 1ml/ l of water; spraying of buprofezin 25%S @ 1 ml/ l at 25 Days after transplanting; spraying of fipronil 5%SC @ 2ml/ l at 35 DAT; spraying of Lecanicillium (=Verticillium) lecanii (1x 10⁸ cfu/ g) @ 5 g/ l at 45 DAT; spraying of chlorfenapyr 10%SC @ 1.5 ml/ l at 55 DAT; spraying of neem oil 1% at 65 DAT; and subsequent rotation were the most effective modules, also giving maximum yield. The least incidence of mite was observed with the integrated module, and that of thrips, in the integrated module, the next best being the chemical module; and in terms of cost benefit ratio too, integrated module was the best (1: 4.2).
