Abstrakt: To determine the efficacy of newer insecticides against major sucking pests in cotton, a field study was undertaken at All India Co-ordinated Research Project on Cotton, Chamarajanagar, University of Agricultural Sciences, Bangalore during 2021-22. Totally three sprays were taken at different intervals by using seven insecticides. The sucking pests population count were observed at pre and three, seven and fourteen days after each spray. The mean of three sprays evidenced the superiority of flonicamide 50 WG by recording least number of leafhoppers (2.17/3 leaves) and aphids (10.34/3 leaves) population with percent reduction of 74.41 per cent and 68.54 per cent, respectively followed by dinotefuran 20 SG @ 0.3 g/L and pyriproxyfen 10 EC @ 2 mL/L. Among the different newer molecules, significantly less incidence of thrips (3.47/3 leaves) and whiteflies (1.10/3 leaves) were noticed in spinetoram 11.7 SC treated plots with maximum percent reduction. Among the treatments, the higher seed cotton yield (2020 kg/ha) was recorded in flonicamide 50 WG with 90.20 per cent increase over control. [ABSTRACT FROM AUTHOR]
