Brief Project Summary:

Meloidogyne enterolobii is an introduced root-knot nematode species to North Carolina. This species has a broad host range (including many vegetables, field crops, and weeds) and threatens profitable soybean production in this state by causing severe root galling. The species is more aggressive than the other endemic root-knot nematode species found in North Carolina. Management of this species is difficult, as it appears to increase population densities to damaging levels even with fumigation. Fumigation for general nematode control in soybean are limited due to the costs of application and the limited economic return with their application. Identification of non-fumigant nematicides most...

Information And Results
Project Deliverables

Cover crops that are non-host to M. enterolobii will be identified and their suppressive effect on the nematode quantified. These data will be compared to the outcomes of the cover crop screening performed in 2021 for robust confirmation of results. Data on the use of RKN resistant soybean and fluopyram-containing chemical nematicides for control of M. enterolobii will be generated. This information will summarized into presentations, fact sheets, and other extension communications through NC State University. This project will generate a peer-reviewed publication to share information to the scientific community to support management of Meloidogyne enterolobii and other root-knot nematodes in soybeans.

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
