Abstract
The trials were conducted to evaluate the efficacy of various insecticides against sucking pests viz., thrips, mite and whitefly of chilli at Rajasthan College of Agriculture, Udaipur during Kharif 2018 and 2019. The chilli variety VNR 102 was sown in a Randomized Block Design with seven treatments and three replications. The treatments were Pyriproxyfen 5% + Diafenthiuron 25% SE in comparison to the products viz., Diafenthiuron 50% WP, Pyriproxyfen 10% EC and Fenpropathrin 30% EC. All the treatments were found to be effective in reducing the pest population over control. The best treatment in reducing the pest population was Pyriproxyfen 5% + Diafenthiuron 25% SE@ 1000ml/ ha with per cent reduction of 63.03, 76.90, 73.47 and 75.25, 77.80, 74.48 at 5, 10 & 15 days after first and second spray, respectively. The next effective treatment was Pyriproxyfen 5% +Diafenthiuron 25% SE @ 750 ml/ ha followed by Diafenthurion 50% WP, Pyriproxyfen 5% +Diafenthiuron 25% SE @ 500 ml/ha,Pyriproxifen 10% EC and Fenpropathrin 30% EC.
