Brief Project Summary:

Previous studies have shown that morning glory is a symptomless host of soybean vein necrosis virus and can act as a source of inoculum for soybean fields. Characteristic symptoms of the disease include brown necrotic blotches along major veins of the upper and lower leaf surface, resulting in a scorched appearance of damaged leaves. Morning glory is considered one of the top 10 most common weeds in Alabama, suggesting the weed may play a significant role in the disease cycle of SVNV in the state. This project determines if morning glory populations in Alabama are acting as a source of SVNV.

Information And Results
Project Deliverables

A survey will be conducted to sample weeds from the edge of 10-15 soybean fields in North Alabama where SVNV was detected at high levels in 2013 and 2014. At each site 20 leaves from non-symptomatic MG plants will be collected to test for the virus. We will also sample other weed species around these fields to determine if they might also be acting as a source of SVNV.

Final Project Results

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.
