Resumo

Bare-root dip treatment of tomato seedlings with undecomposed and decomposed extracts of castor cake and leaves significantly reduced root-knot development in pre-infected seedlings and in those which were inoculated with 2nd state juveniles of Meloidogyne incognita after dip treatment. Suppression of root-knot development was greater in pre-infected seedling than in those inoculated after dip treatment. Oilcake extracts were more effective than leaf extracts and decomposed extracts more effective than undecomposed extracts.
