Have Problems with Sudden Death Syndrome in Soybeans?

Aug 12, 2022

By Madison Kessler and Rodrigo Onofre

Researchers at K-State are in search of soybean fields showing symptoms of Sudden Death Syndrome (SDS) to sample.

What is Sudden Death Syndrome (SDS)?

It is a soil-borne fungal disease caused by Fusarium virguliforme. Infection and colonization begin shortly after planting and the pathogen produces a toxin that causes above-ground symptoms later in season.

What are the symptoms?

Root symptoms include necrosis (death) and above-ground symptoms include interveinal leaf chlorosis (yellow discoloration of the tissue) and necrosis (Figure 1). Under the right environmental conditions, these symptoms appear as early as the start of flowering.

What are the environmental conditions?

SDS is observed more when soybeans are planted in cool, wet soils followed by wet conditions at the beginning of flowering.

What are the management options?

Seed treatment, resistant cultivars, planting date, tillage, and crop rotation.

Video: Agriculture Secretary Rollins Speaks at American Farm Bureau Federation Convention in Anaheim

One of the highlights at the 2026 American Farm Bureau Federation Convention in Anaheim, California, was an address by U.S. Secretary of Agriculture Brooke Rollins. During her remarks, she thanked America’s farmers and ranchers and said the Trump Administration is fully aware that food security is national security.

She also acknowledged the challenging times in Farm Country with low commodity prices and high input costs and said that’s why the President stepped in to help with the recent Bridge Assistance Program.

Montana Farm Bureau Federation Executive Vice President Scott Kulbeck says that Farm Bureau members are appreciative of the help and looks forward to working with the American Farm Bureau Federation and its presence in Washington, DC to keep farmers and ranchers in business.

Secretary Rollins said the Trump Administration is also committed to helping ranchers build back America’s cattle herd while also providing more high-quality U.S. beef at the meat case for consumers.

And she also announced more assistance for specialty crop producers who only received a fraction of the $12 billion Farmer Bridge Assistance (FBA).

It’s important to note that producers who qualify for Farmer Bridge Assistance can expect the Farm Service Agency to start issuing payments in late February. For more information, farmers and ranchers are encouraged to contact their local USDA Service Center.
