Fruit borer Helicoverpa armigera (Hübner) and two spotted spider mite, Tetranychus urticae (Koch) are destructive pests exerting a high crop loss in tomato. The field experiment was carried out to evaluate the efficacy of some insecticides and acaricides against H. armigera and T. urticae at College of Agriculture, Vijayapura. The results revealed that chlorantraniliprole 18.5% SC @ 0.15 ml/ l followed by spiromesifen 22.9% SC @ 0.5 ml/ l was recorded lowest fruit borer larvae (1.25/ plant). The treatment chlorantraniliprole 18.5% SC @ 0.15 ml/ l recorded lowest fruit damage (8.91/ plant) at 15 DAS. The treatment spiromesifen 22.9% SC @ 0.5 ml/ l recorded lowest number of two spotted spider mites (2.30/ square inch of leaf area) at 15 DAS. The combination treatment of chlorantraniliprole 18.5% SC @ 0.15 ml/ l followed by spiromesifen 22.9% SC @ 0.5 ml/ l found most effective treatment to control both the above pests on tomato.
