All soybean and sorghum cultivars tested were suitable hosts for the ring nematode, Criconemella xenoplax. Small grain cultivars and cotton were either poor hosts or nonhosts as compared to peach. The wheat cultivars Stacy, Coker 916, and Fla-302 were found to be nonhosts and appear to be allelopathic toward C. xenoplax. Rotation of land previously planted to peaches with wheat may prove to be an alternative preplant control method for C. xenoplax and the peach tree short life complex.
