The researchers will evaluate both existing and new soybean cultivars with reported resistance to the economic nematodes to determine their actual level of performance in production fields. They will identify those cultivars that will provide mitigation of nematode damage under field environments and with local races and biotypes of the pathogens. They will also begin to develop an experience base as well as an experimental data base on the use and impact of nematicides in managing soybean nematodes. This database will include information on novel chemicals and strategies for existing chemicals involved in effective management. They will also begin a search for potential biological control...
