Abstract
Soil insecticides, insecticide application procedures, and nematicides were evaluated from 1986 to 1989 in field plots of ‘Jewel’ sweet potatoes, Ipomoea batatas L., to control wireworms, (Conoderus spp. Coleoptera: Elateridae), and the rootknot: nematode, Meloidogne incognita (Kofoid & White) Chitwood. Experimental application procedures for insecticides were preplant broadcast and incorporate, postplant band and incorporate, and broadcast at root enlargement. The least injury to the harvested sweet potatoes by wireworms and nematodes occurred in plots treated with the nematicide 1, 3-0 and with the insecticide chlorpyrifos applied as a postplant band a subsequent application of diazinon broadcast at root enlargement. Sweet potatoes in plots that received no nematicide or the nematicides aldicarb or fenamiphos had more wireworm and nematode infestation than plots injected with 1,3-0. Chlorpyrifos applied as a postplant band gave better wireworm control than chlorpyrifos applied preplant and incorporated.
