Control of Pratylenchus brachyurus with Selected Nonfumigant Nematicides on a Tolerant and a Sensitive Soybean Cultivar
AbstractA field study was conducted to evaluate soybean cultivar sensitivity to Pratylenchus 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 had fewer nematodes 40 days after planting than nontreated plots. Plots planted with Forrest and treated with carbofuran had a greater yield than the untreated controls. Key words: aldicarb, carbofuran, chemical control, fenamiphos, Glycine max, lesion nematode, Pratylenchus brachyurus.
