A greenhouse experiment was carried out to study the effect of powdered seeds of pig bean (Canavalia ensiformis) incorporated into the soil, for the control of Meloidogyne incognita race 1 in tomato (Lycopersicon esculentum) plants. Autoclaved soil was amended with 2.5, 5.0, 7.5 and 10.0 g of powdered seeds/kg of soil. Soil without amendment served as control. For comparison, the nematicide Carbofuran was included as an additional treatment. Nematode was controlled at rates above 5.0 g. Gall and egg mass indexes were reduced by 48% and 64%, respectively, with the application of 10 g of powdered seeds/kg of soil.
