Traditionally, M. chitwoodi is controlled with
chemical nematicides, many of which risk
suspension for use on potatoes due to health and
environmental concerns. It is essential to develop
and refine alternative strategies for controlling
Columbia root-knot nematode now, so that
productive and profitable potato acreage will not
be lost if...
