Brief Project Summary:

This project provides a current soybean cyst nematode race survey in North Carolina. Frequent sampling is necessary to monitor potential race shifts, especially given diversity in these fields. Identifying races assists growers in implementing control practices to manage SCN. The primary goal is to gather preliminary data to identify percentage of race by type and location. To do this, research identifies races present and determine which control practices are necessary for successful SCN management and gathers preliminary data to determine the need for a more comprehensive SCN survey of North Carolina.

Final Project Results

Based on the data generated from 30 samples, race 2 (~87%) was the predominant race followed by race 5 (~10%) and race 4(~3%). Findings suggest that host resistance currently available to producers may not adequately manage current races unless varieties resistant to the above races become available. Data supports that rotations with a non-host crop or chemical treatment remain viable options to effectively manage soybean cyst nematode. A more comprehensive survey including additional soybean producing counties will be required to get a more accurate percentage of current races identified and determine if additional races exist.

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.
