Brief Project Summary:
Testing of over 1,000 soil samples from 60 counties in Ohio revealed that more than 65% had SCN. Moreover, the current and most prevalent SCN population in Ohio is HG type 2-, which can reproduce on PI 88788 at levels above 10% and up to 80% of a susceptible soybean. The goal of this effort is to continue raising awareness of this threat to Ohio soybean growers and provide the opportunity to test soil samples and to determine the SCN virulence profile. Additionally, this work leverages the dataset created since 2018 and evaluates the relationship between SCN reproduction, soil texture, soil health measurements, other nematodes and cropping history.

Information And Results
Project Summary

The soybean cyst nematode (SCN) remains the most economically important pathogen of soybean because it can significantly reduce yield with no visible symptoms. From 2018 to the date, with funding from the soybean check-off through Ohio Soybean Council and The SCN Coalition, we received over 1,000 soil samples from 60 counties in Ohio and processed for SCN. More than 65% of these soil samples had SCN. Moreover, the current and most prevalent SCN population in Ohio is HG type 2-, which can reproduce on PI 88788 at levels above 10% and up to 80% of a susceptible soybean. Our goal is to continue raising awareness of such an important threat to Ohio soybean growers and provide them the opportunity to test soil samples for SCN and to determine the SCN virulence profile (obj.1). Additionally, we will leverage on the dataset created since 2018 and evaluate the relationship between SCN reproduction, soil texture, soil health measurements, other nematodes, and cropping history (obj. 2).

Benefit To Soybean Farmers

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.
