Three insecticides were mixed in four bait-base combinations and applied to a potato field with high cutworm infestation. Population and mortality counts were taken 5 days before bait application and 2 and 4 days after. At 4 days after the baits were applied, those with Basudin and Phosvel gave better kills than Sevin, there were no differences between the bases pig meal, citrus pulp, saw dust and coir dust, but Phosvel in pig meal and citrus pulp gave the highest mortality.
