Brief Project Summary:

Evaluation of the IUfect of Cover Crops on Soybean Cyst Nematode is a request for the second year of funding for the project that was initiated in 2015 at the request of MSPC. Soybean cyst nematode is a key limiting factor in soybean production in both Michigan and throughout the world. While it is currently being managed through the use of resistant varieties, there is a distinct need for new technologies for controlling this pest.

Mr. Jeff Shoemaker was hired as a Graduate Research Assistant for this project. The research is progressing in a satisfactory manner. If the research project is successful, it could have a major impact of SCN management throughout Michigan and the...

Information And Results
Project Deliverables

The research protocol for SCN Trap cops will include a comparison of nematode development associated with a SCN susceptible soybean variety, SCN resistant (Pl548402) soybean variety, beet cyst nematode trap crop and three potential SCN trap crops (BioFum, Cappichino and Terranova). Greenhouse conetainers will be used for this 56-day protocol, with each of six replicate experimental units being destructively sampled every 14 days and SCN development evaluated using root staining technology. As soon as the SCN trap crop protocol has been validated (repeated at least once), it will be used to evaluate a series (most likely six to twelve) other potential SCN trap crop varieties. Under 2015 field conditions at the MSU Collins Road Farm, the necessary controls from the trap crop protocol and a series of potential SCN Trap Crops will be evaluated for SCN population density reduction in 152 ft. field plots. Six replicates of each variety will be destructively sampled and evaluated using root-staining technology 30 and 6o days after planting. The SCN egg densities at 2015 soybean harvest will be
determined in addition to the overwintering cyst/egg population densities, evaluated in the spring of 2016.

Final Project Results

Updated February 21, 2017:
SCN life cycle with respect to the discovery of a highly effective trap crop: egg activation; 2nd stage juvenile hatch; 2nd stage juvenile emergence; successful soybean root finding; successful root penetration; successful within root migration; successful identification of a suitable feeding site; release of an incompatible chemical signal; plant failure to produce functional nurse cells; SCN death; Rf=0.01-0.10.
2015-2016 SCN trap crop research activities:
four field trials - 2 in Lansing and 1 each in Dundee and Edwardsburg; 7 greenhouse experiments; 17 plant cultivars evaluated.

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.
