Three field experiments with dusts, three with spray formulations and two demon- stration trials were conducted during 1971-74 for the control of the bengalgram pod borar, Dust formulations were superior to the sprays in reducing the pod borer, damage and increasing the yield. Among the dusts, endosulfan 4 per cent was superior followed by carbaryl 10 per cent, methyl parathion + DDT 10 per cent. lindane 0,65 per cent and malathion 4 per cent in efficacy. Endosulfan 4 per cent dust consistently recorded higher yields and tower pod borer damage.
