Soybean Disease Guides Now Available

Tailored to Missouri growing conditions and disease prevalence, the Guide is a quick reference for growers to keep in the truck console and on their phone or tablet.

With planting season just around the corner, Missouri soybean farmers have a fresh option to prepare for scouting. The Soybean Disease Field Guide features full-color photos of viral, stem, seed and foliar diseases affecting soybean throughout the growth cycle, as well as written descriptions of each.

“Missouri has a broad range of growing conditions for soybeans, from soil types and weather conditions to disease pressures,” said Kyle Durham, a farmer from Norborne and chairman of the Missouri Soybean Merchandising Council. “Providing timely, accurate information is one of the ways the Merchandising Council serves farmers through their soy checkoff, and we’re proud to release the Soybean Disease Field Guide for the 2021 growing season.”

The guide, first released in 2017, received a full refresh for 2021 with new photos and additional disease information. The 2021 edition includes special attention for diseases most impacting Missouri growers, such as Sudden Death Syndrome (SDS), as well as emerging diseases and less-severe afflictions like Septoria Brown Spot.

Each disease section includes details on the likely timing for scouting, impact on yield, and management recommendations. The guide also includes reminders on year-round best practices to minimize disease in soybean fields.

The printed guide has coated pages and a lay-flat binding for maximum durability in the field. An electronic version is also available.

Printed guides are available at no charge for farmers, industry partners and students with an interest in plant science thanks to support from soybean growers’ checkoff dollars. Request copies from the Missouri Soybean Merchandising Council online at or by calling (573) 635-3819.
