Comparison of Methods of Application of Oxamyl for Control of Heterodera sacchari on Sugarcane Plants

Abstract

Foliar applications of oxamyl prevented Heterodera sacchari Luc and Merny juveniles from invading roots of 10-day-old sugarcane seedlings. Two and three sprays of 1000 and 2000 g/ml applied at 5 day intervals were more effective than 1, 2, or 3 sprays of 500 g/ml of oxamyl, sprays of 2000 g/ml were phytotoxic. Dipping of sets and soil sprays at 500 and 1000 g/ml were effective in reducing nematode invasion.
