The interaction between the nematicides aldicarb, carbofuran and terbufos and the herbicides clomazone, metribuzin and tebuthiuron, applied on sugarcane plantations, was evaluated in an experiment conducted in sandy soil. Plots treated with metribuzin + terbufos or tebuthiuron + terbufos presented the most severe phytotoxicity symptoms. The herbicides metribuzin and tebuthiuron caused high phytotoxicity and tebuthiuron reduced the number of stalks in the plots, five months after planting. In spite of this, yield reduction due to nematicide and herbicide application was not observed. Aldicarb and carbofuran increased sugarcane yield at 12 ton ha-1. Plots treated with clomazone produced significantly more than plots treated with metribuzin.
