Thrips and fruit borers culminate huge economic losses in chilli in India and abroad. New registrations for pest control products are costly to develop under Indian context. Tank mixes should be of choice in situations where multiple pests are present. Bio-efficacy of pre-mix insecticides CPL 1535 @ 400,500,750,1000 ml/ha were undertaken against chilli thrips, and fruit borer. Best result (% reduction in pest number and fruit damage) was obtained with the application of higher dosages (500, 750 and 1000 ml/ha) . The maximum yield was obtained in higher dosages (16.15-18.00 q/ha) and the treatments exhibited 47.86-53.23 % increment in yield over untreated control. Survival population of thrips (2.25-2.87 /leaf) were minimum in the treatments with high dosages of CPL 1535. CPL 1535 was soft to natural enemies (Menochilus sp and Coccinellasp). Their number varied between 0.50-0.84 in different treated plots 15 DAT. CPL 1535 was not phytotoxic at higher dose(1500 ml/ha). Dose recommendation of CPL 1535@ 750 ml/ha is cost effective.
