Abstract
Ethoprop, cadusafos (FMC 67825) and 1,3-D were evaluated for control of Meloidogyne chitwoodi on 'Russet Burbank' potato (Solanum tuberosum). Based on tuber infection, cadusafos at broadcast rates of 10.1, 13.4, and a split application of 6.7 + 6.7 kg a.i./ha, and a 30-cm-wide band treatment of 6.7 kg a.i./ha were comparable to a commercial treatment of 1,3-D at 176 L a.i./ha. Ethoprop, the nonfumigant nematicide used most frequently on potato for control of root-knot nematodes in the northwestern United States, did not reduce M. chitwoodi infection of tubers.
