Growers have been experiencing extreme damage and plant death due to root-knot nematode even when growing soybean varieties reported to be resistant. Repeatedly growing resistant soybeans may have selected for new races or even species of root-knot nematode. This project aims to identify the cause of increased yield losses on Southern root-knot resistant soybeans. It uses test sites to develop model nematode management schemes for typical farms. This includes use of total farm nematode surveys and the resistance status of varieties tested at each location. The work then provides growers with visual evidence of the problem and improved management practices.
