Abstract:	A field study was conducted in North Carolina, USA, to evaluate soyabean cultivar sensitivity to P. brachyurus and selected nonfumigant nematicides for control of this nematode. Essex, a tolerant cultivar, yielded more than Forrest, a sensitive cultivar, in an infested field. Plots treated with aldicarb, carbofuran and fenamiphos (all at 2.24 kg a.i./ha) had fewer nematodes 40 days after planting than untreated plots, but yields were not consistently increased due to late-season drought stress and an acid subsoil. Plots planted with Forrest and treated with carbofuran had a greater yield (150%) than the untreated controls.
