Brief Project Summary:

Soybean cyst nematodes and root-knot nematodes cause damages to soybean throughout North Carolina. Resistance is available for several races of SCN; however, heavy reliance on host resistance for SCN management may lead to a race shift within a field. Crop rotation is the best control method nematode, but some regions lack economical options for crop rotation. This research provides information regarding chemical control of SCN and RKN in soybean, including seed treatments containing chemical or biological agents for control, as well as applications of chemical or biological agents. The main objective is to determine the best chemical management practice to reduce the impact of SCN and RKN.

Key Benefactors:
farmers, agronomists, extension agents

Information And Results
Final Project Results

Seed treatments have been recently developed for use as nematode control in soybean production; however, little information was available for North Carolina producers. Given the different environments that soybean is produced in within the state, the level of control seed treatments may differ between regions and nematode populations. To address this, seed treatments were assessed in Hyde, Johnston, and Moore counties. Seed treatments did not improve yields at any site, nor were nematode populations or damages reduced by the seed treatments. This study is currently being repeated in 2019 on several other sites with several different nematode species to determine the best fit for seed treatments in NC soybean production.

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.
