Abstract The efficacy of powders of certain herbs for grain protection against pulse bruchid Callosobruchus maculatus in stored black gram was evaluated. It was observed that clove (8.0 adults), sweet flag rhizome (6.0 adults), pepper (9.67 adults) and tobacco leaf powders (16.67 adults) were the effective ones as grain mixing at 0.4%. There was reduced adult emergence in these. These powders were further evaluated under dual choice conditions for their repellent effect. The adult emergence and % grain damage at 40 and 80 days after release were observed to be negligible in these. The spice tablets made of sweet flag and clove powders alone or fortified with clove oil when placed on the grain surface offered protection.
