Meloidogyne enterolobii is an introduced root-knot nematode species to North Carolina. It has a broad host range including many vegetables, field crops, and weeds, and causes severe root galling. It is more aggressive than the other species found here, and management is difficult, as it appears to increase population densities to damaging levels even with fumigation. Previous research resulted in no resistance being found. This project screens selected PI lines with known resistance to other root-knot nematode species and soybean cyst nematode to assess potential mechanisms for resistance and identify the sensitivity of soybean lines to this new root-knot nematode. The project also screens several cover crops for their host status and effectiveness in suppressing this nematode.
