Combinations of flooding, solarization, and amending soil with yard waste compost (YWC) treatments were evaluated for control of root-knot nematodes (Meloidogyne arenaria). Experiments were conducted at Gainesville, Florida for 12-wk periods in the summer of 1996 and 1997 in mesocosms containing an Arredondo fine-sand. Flooding soil induced anaerobic conditions with soil redox potentials near-200 mV in both years. Flooding decreased soil root-knot nematode populations in the order of: continuous intermittent non-flooded with values (J2/100 cm) of 9, 10, and 36 in 1996, and of 5, 23, and 212 in 1997, respectively. The number of galls found in tomato (Lycopersicon esculentum c.v. Rutgers) roots as a result of both intermittent and continuous flooding in both years were 1. Endogenous soil populations of ring (Criconemella spp.) and stubby-root (Paratrichodorus spp.) nematodes were also reduced by flooding. Average daily maximum soil temperatures in solarized plots were in the order
