| Popis: | Tree growth, fruit production and population dynamics of three root-knot nematodes, Meloidogyne incognita, M. arenaria and M. javanica were evaluated during six years in a peach planting. The treatments were: 1) preplant soil fumigation with methyl bromide at 450 kg/ha + mycorrhizae at planting, 2) root-knot nematode + Dactylella oviparasitica (S isolate), 3) root-knot nematode + soil from an established peach orchard, and 4) root-knot nematode alone. These four treatments were evaluated under normal and high irrigation regimes. Methyl bromide treatment improved tree growth, fruit production, and nematode control most. D. oviparasitica did not improve growth. The high irrigation regime counteracted the detrimental effects of root-knot nematode without reducing the nematode population. After 6 years root-knot nematode numbers were declining in all treatments except those previously free of the nematode. |
