abstract
Field experiments were conducted to evaluate the efficacy of novel insecticides against thrips (Scirtothrips dorsalis Hood) and mites (Polyphagotarsonemus latus Banks) on chilli (Cv. Byadgi dabbi) during November, 2016 at HREC, Haveri. Among all the chemicals, thiamethoxam 25 WG at 0.20 g a.i. ha^-1 was found superior with a lowest mean thrips population, Leaf Curl Index (LCI) and highest dry chilli yield, per cent reduction over control and per cent increase in yield over control of 0.81, 0.7 and 9.55, 80.00 and 43.45 per cent, respectively followed by cyantraniliprole 10 OD @ 1.00 g a.i. ha^-1. The highest net profit was obtained from the treatment thiamethoxam 25 WG at 0.20 g a.i. ha^-1 (Rs. 97660) with benefit cost ratio (1: 3.71). Likewise, diafenthiuron 50 WP 1.0 g a.i. ha^-1 and Spiromesifen 24 SC @ 1.0 ml/l found significantly superior against mites incidence. Diafenthiuron 50 WP 1.0 g a.i. ha^-1 recorded least mean mite population (3.07 mite/plant). Spiromesifen 24 SC @ 1.0 ml/l registered lowest (LCI), highest dry chilli yield, per cent increase in yield over control and per cent reduction over control of 0.74, 11.94, 43.47 and 77.84 with a net returns of (Rs. 127660) and (1:4.23) of benefit cost ratio. Suggesting that these are feasible, excellent in managing the chilli sucking pests and adoptable by the farming community.
