Abstract

Seventeen compounds were applied as preplant or lay-by incorporated treatments and were evaluated in replicated small plot trials for management of soil-borne insects, and foliar insecticides were applied for management of leaf-feeding insects. Although several treatments reduced damage to sweetpotato roots, some soil incorporated treatments resulted in higher insect counts for one or more species or more insect damaged sweetpotatoes than the water treated check plots. All treatments used for dingy cutworm were effective, however pyrethroids were less effective than were other compounts evaluated in the trial. The evaluation for foliage feeding insects resulted in significant differences in lady beetles and tortoise beetles compared to the check plots, but insect damage to sweetpotato roots did not differ between treatments.
