Brief Project Summary:

Soybean is host to many plant-parasitic nematodes. Soybean cyst nematodes is the primary problem, causing other nematodes that attack soybeans to be overlooked. This project conducts field surveys in soybean-growing counties of the state, to identify incidences of predominant nematode genera beyond SCN and their population levels. Nematodes isolated from fields will be used to study virulence and reaction of commonly grown soybean cultivars. Based on predominant nematode populations present in the field, a host reaction and/or virulence study will be conducted in year 2 to inform growers about selecting appropriate cultivars depending on the problematic nematodes in their fields.

Key Benefactors:
farmers, agronomists, Extension agents

Information And Results
Final Project Results

Update:
Mini surveys were conducted in MD and DE soybean field for identifying parasitic nematodes in soybean-producing counties. The results were disseminated to MD farmers through a Factsheet published in UMD Agronomy News. We also prepared and published another Factsheet providing details on how to correctly sample the soils for nematode analysis in the same issue. Attached are the published factsheets being submitted as deliverables of the project. We received funding for Year-1 only, and did not revise the project for Year-2 because of Covid-19. Students could not be hired in 2020 summer and fall season and the PI had limited access to her lab and the field.

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.
