Abstract

Soil amendments with dry top and root material from alfalfa (Medicagosativa) were evaluated for their nematicidal effect on the root-knot nematodeMeloidogyne incognita on tomato either in potting mixes or in field conditions. Allamendments in potting mixes suppressed root and soil population densities of rootknotnematodes compared to nontreated and chemical controls. Amendmentsuppressiveness on M. incognita differed between top and root material and amongrates. In field conditions, soil amendments with 20 or 40 t ha-1 of a pelleted M. sativameal increased tomato crop yield and reduced soil population densities and rootgalling of M. incognita. As saponins were hypothesized to be at least partlyresponsible for the nematicidal activity of Medicago materials, biomolecular aspectsof plant-nematode interaction were preliminarily investigated on M. incognitajuveniles treated with saponins from M. sativa.
