Studies on the Bio-efficacy of new insecticide molecules against insect pests in cotton aicrp on cotton

Ambarish S, Shashi Kumar C, Somu G and Shivaray Navi

A field experiment was conducted at AICRP on Cotton KVK, Chamarajnagar, UAS, Bangalore, during 2016-17 to assess the efficacy of different combination insecticides. Totally 3 sprays were taken up at 40, 80 and 120 days after sowing using manually operated knapsack sprayer. The mean of three sprays indicated that, application of Spinetoram 10% w/w + Sulfoxaflor 30% w/w WG @ 140 g ai/ha recorded a lower number of whiteflies per leaf (0.41) and Leaf hopper (0.48). Whereas the lower number of aphids per leaf (1.71) and thrips (0.77) were recorded in the application of Sulfoxaflor 30% @ 108 gai/ha. While untreated control recorded the higher number of thrips (13.22), leaf hopper (3.71), whiteflies (2.88) and aphids (36.33) per leaf. The incidence of bollworm was lowest in Spinetoram 10% w/w @ 36 g ai/ha.
