Abstract: Bio efficacy studies were carried out at All India Co-ordinated Research Project on cotton KVK, Chamarajanagar UAS, Bengaluru, during 2017-18 for sucking pests and bollworms with new insecticide molecules. Totally three sprays were taken at different intervals. The sucking pests population was observed at pre and seven days after every spray. The mean of three sprays indicated that, spinetoram 10%+ sulfoxaflor 40%WG @ 350 g/ha recorded lower number of aphids (12.80 /3 leaves), leafhoppers (1.02/3 leaves), thrips (5.67/3 leaves) and whiteflies (1.00/3 leaves). Significantly less incidence of Helicoverpa armigera (1.20 larvae/plant) and Pectinophora gossypiella (1.92 larvae/10 bolls) were recorded in spinetoram 10%+ sulfoxaflor 40%WG @ 350 g/ha with maximum seed cotton yield (17.60 q/ha).
