Experiment was carried out to study the effect of different insecticides applied through stem injection (DDVP 76% EC@8.00% and Metarhizium anisopliae 1x109 CFU's/ml2 100.00ml/l), soil incorporation (Chlorantraniliprole 0.4%G @20.00 and 15.00gm/vine and Fipronil 85% WG@ 20.00 and 15.00gm/vine), stem smearing (microbial consortium@1.00ml/l) and foliar spray(microbial consortium@ 1.00ml/l) for the management of Cerambycidae stem borer C. scabrator of grape between 2016-18 in the grape orchards of Vijayapura (Karnataka: India). The results revealed that stem injection with DDVP 76%EC @ 8.00% was highly effective by recording 100.00 reduction in live tunnels. Soil application of Chlorantraniliprole 0.4%G @ 20.00gm per vine was found next effective treatment. Highest cost benefit ratio was obtained in treatment with soil application of Chlorantraniliprole 0.4% G @ 20.00 g/vine (1:2.83).
