Bioefficacy studies of various treatments against painted bug revealed that seed treated with imidacloprid 48 FS @ 4g, 5g and 6g /kg seed and thiamethoxam 30 FS @ 4g, 5g & 6g /kg seed and application of methyl parathion 2% dust @ 25 kg/ha as a standard check provided significant reduction in population and recorded higher seed yield over control. Seed treated with thiamethoxam 30 FS @ 6 g/kg seed showed good control of painted bug with higher seed yield. However, it was statistically at par with seed treated with thiamethoxam 30 FS @ 5 g/kg seed and seed treated with imidacloprid 48 FS @ 6g /kg seed during both the years of study. Incremental cost-benefit ratio indicated that the maximum net return was obtained with seed treatment of thiamethoxam 30 FS @ 6 g/kg seed (Rs. 32472/-) whereas, higher B: C ratio (1: 123.50) was observed in seed treared with thiamethoxam 30 FS @ 5 g/kg seed.
