An ongoing study is investigating how different types of cover crops influence soybean cyst nematode (SCN) populations across Illinois fields. With 13 established cover crop sites throughout the state, researchers are collecting data to help farmers refine their SCN management practices.
Dr. Jason Bond, who is leading the research, provided an update on the project’s progress. “We’re currently processing soil samples collected from the fall and early winter,” he said. “These samples represent the final counts for cover crop trials that began in the fall of 2023, as well as those started in the fall of 2024.”
The research team is working on developing targeted DNA sequencing techniques to better understand how cover crops affect SCN. In the coming weeks, they will continue analyzing data, sequencing the soil microbiome, and collecting spring soil samples from the 2024 trials.
This Illinois Soybean Checkoff-funded project is aimed at providing Illinois soybean farmers with improved strategies for managing SCN with cover crops.
