Abstract: Nematicidal plants means phytochemical compound that had kill nematode. Nematicidal plant resources in this paper were reviewed including most of Asterales and Fabales. Active substances and its metabolites were separated from different plants and the different parts of the same plant. The mode action and the mechanism action of nematicidal plants and its active substances to plant parasitic nematodes were illustrated. The factors that effected on nematicidal activity were analysed. The active substances of extraction were tested by in vivo and in vitro method. And the problems that make use of nematicidal plants to control plant parasitic nematodes were also discussed. In order to seek for a new generation nematicidal plants and its active substances in the next years,we must continue to expand the investigation and exploration of nematicidal plant resources, explicit the mechanism action of nematicidal plants to plant parasitic nematodes, research the active ingredient of nematicidal plants and its application,and strengthen cultivar resources to resistant nematode from molecular level.
