Brief Project Summary:

Nematodes are often called the silent yield robber because farmers often don’t know they are present. They cause few above-ground symptoms. Pressure is expected in the sandy soils of Delaware, Maryland’s eastern shore and other Atlantic region states, but famers need soil numbers to know for sure. To learn more about nematode populations in this region, a survey provides a baseline. It comprises soil samples from farms with known nematode history and no knowledge of existing pressure. Analysis of those soils samples found soybean cyst nematodes, root-knot nematodes and lesion nematodes.

Information And Results
Project Deliverables

Effective communication and outreach are critical components of this proposal. Multiple University resources including the DE Weekly Crop Update, MD Agronomy News, and factsheets will be used to disseminate data. Members of the project are active on social media and will share project updates on platforms like Twitter and Instagram. News outlets like the Delmarva Farmer (circulation: 13,000) will also be notified of project findings. By hosting a nematode focused webinar upon completion of the project, this project aims to bring together researchers from across the region to engage in dialogue on improving understanding and management of nematodes within Mid-Atlantic soybean production.

Final Project Results

Updated June 14, 2022:
Fields and grower collaborators were identified for sampling as part of objective 1 and soil samples were collected in Aug-Sept. Two field sites were identified for objective 2. One site is in Georgetown, DE and the other in Wye Mills, MD. The DE site has a history of high nematode populations, while the MD site has lower nematode pressure. All soil samples have been collected and we are waiting for conditions to allow for harvest. We will post the final report once the yield data is available. Project updates will be shared in a regional webinar November 16, 2021 and in the DE Weekly Crop Update and MD Agronomy news.

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.
