Abstract
Two experiments, each lasting 17 to 18 months, were conducted to study the feasibility of rice rotation to reduce Cylas formicarius formicarius F. infestation in sweet potato. Planting rice after the harvest of weevil infested sweet potato does not reduce the weevil damage in the ensuing sweet potato crop if the source of weevil is present in the vicinity. Rice rotation initiated away from the insect source, coupled with removal of the common wild-host Ipomoea sp., can reduce weevil infestations and maximize the effectiveness of carbofuran transplant dip treatment.Keywords
