Abstract
Phenamiphos applied at 6.7 kg ai[active ingredient]/ha through a solid set or a center pivot irrigation system with 28 mm of water effectively controlled root-knot nematodes, M. incognita, and resulted in greater snap bean growth and yields irrespective of growing season, tillage method or cover crop system. The percentage yield increases attributed to this method of M. incognita control over nontreated controls were 45% in the spring crop, and 90 and 409% in the fall crops following winter rye and fallow, respectively. Root galling was not affected by tillage systems or cover crop, but disk tillage resulted in > 50% reduction in bean yield compared with yields from the subsoil-bed tillage system.
