Control of Meloidogyne chitwoodi

At the Annual Meeting of the American Phytopathological Society (APS) and Mycological Society of America (MSA) in Portland 1992 it was reported that Meloidogyne chitwoodi (potential EPPO A2 pest) on potato can be managed by rapeseed and sudangrass as green manure. Scientists of the Washington State University and the Oregon State University found in greenhouse experiments that shoots and roots of rapeseed as well as shoots, but not roots from sudangrass reduced M. chitwoodi populations. The zone of incorporation was protected from a recolonization of the root knot nematode for a time period of 6 weeks. In field experiments the incorporation of rapeseed and sudangrass into soil as green manure resulted in the reduction of M. chitwoodi damage on potatoes for two consecutive years.
