Abstract
The efficacy of coastal bermudagrass (Cynodon dactylon) as a rotation crop for controt of root-knot nematode (Meloidogyne arenaria) in 'Florunner' peanut (Arachis hypogoea) was evaluated in a 3-year field trial. Coastal bermudagrass-peanut rotation (CBP) was compared with peanut monoculture without nematicide (P - ) and peanut monoculture with aldicarb (P + ). The performance of CBP was also compared with 'Pensacola' bahiagrass (Paspalum notatum)-peanut (BP), and 'Deltapine 90' cotton (Gossypium hirsutum)-peanut (CP) rotations. Each rotation crop was grown for 2 years (1991, 1992) and peanut was planted without nematicide the third year (1993). In contrast with peanut, the alternate crops of bahiagrass, bermudagrass, and cotton did not support M. arenaria populations. In 1993, the lowest numbers of M. arenaria second-stage juveniles (J2) in soil were in plots with CP and BP; these rotations resulted in the highest peanut yields. CBP failed to increase peanut yield and resulted in the highest population densities of M. arenaria J2. In 1993, aldicarb reduced J2 densities in the soil but did not increase peanut yields. Rotations of BP and CP reduced incidence of southern blight (Sclerotium rolfsii) in peanut, but neither CBP nor aldicarb affected the disease.
