Brief Project Summary:
Soybean cyst nematode is adapting to the most commonly deployed resistance derived from PI 88788. This project supports soil sampling that arises from an education campaign from the SCN Coalition to raise awareness of this issue. The project aims to monitor soybean cyst nematode populations in Ohio for the number of eggs/sample, to determine which source of resistance for SCN, Peking or PI 88788, will be most effective across Ohio, and to evaluate additional management practices that limit the impact of soybean cyst nematode in Ohio.

Information And Results
Project Summary

The most economically important soybean pathogen in the U.S. is the soybean cyst nematode (SCN), estimated to cause annual losses of more than $1.2 billion. The use of resistant cultivars remains the most effective means to mitigate the effect of SCN in soybean production. Persistent use of the same source of resistance exerted selection pressure on SCN populations, consequently, shifting their virulence. In other words, nematodes are becoming resistant to the resistance. SCN numbers in Ohio are rising. Our goal is to continue raising awareness and building understanding of such an important threat to Ohio soybean growers. We will provide Ohio soybean growers the opportunity to test soil samples for SCN (obj.1) and to determine the SCN virulence profile (obj.2). The first objective will help us know our numbers to more effectively select the best integrated SCN management strategies; the second objective will help us determine which resistance to SCN will be most effective in Ohio.

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.
