Sudden Death Syndrome Hits Soybeans Across US

Sudden Death Syndrome Hits Soybeans Across US

15 September 2014

ANALYSIS - Due to high moisture levels throughout the Midwest this season, Sudden Death Syndrome (SDS) has hit soybean fields not only in the Midwest, but "any place that soybeans are grown," according to Jennifer Riggs, product development manager with Bayer CropScience.

SDS is a soil borne disease caused by the fungus Fusarium virguliforme. The fungus enters the plant through the roots and causes root rot.

Dr. Riggs describes the damage she has seen in fields across the US and a new SDS solution from Bayer for the 2015 growing season.  

Initial SDS infections occur on the roots and crowns of young soybean plants as early as the seedling stage. SDS produces toxins that cause foliar symptoms including leaf drop, which reduces the plant’s ability to provide nutrients to promote pod fill, leading to aborted pods and, ultimately, yield loss.
