Interpretive Summary:

Technical Abstract: Three sweetpotato genotypes were grown in either conventionally tilled plots (CT) or in a killed-cover crop (KCC) tillage system. In general, injury to sweetpotato roots by soil insect pests was significantly lower in the KCC plots than in the CT plots. Also, injury by sweetpotato weevils was significantly less in the weedy than in the hand-weeded plots. Pitfall traps and fire ant sampling indicated that more beneficial predators were present in the killed cover crop plots.
