Plant-parasitic nematode populations in soil and peach roots were determined in peach tree short-life (PTSL) and non-PTSL orchards in Georgia and South Carolina. Criconemella xenoplax was predominant in all orchards in both states. Other Criconemella spp. detected in this study included C. ornata and C. sphaerocephala, with the former occurring more frequently than the latter. Loamy sand soils were predominant in Georgia and South Carolina PTSL orchards, with pH and percent sand being greater in South Carolina. Soil textural class and C. xenoplax were common factors associated with PTSL orchards in Georgia and South Carolina.
