As soybeans head into the time period where more disease issues begin to appear, a multi-university group including representatives from Canada has released its full series of reference materials that help farmers identify and treat common soybean diseases.
The resources are prepared with assistance from the North Central Soybean Research Program, and can be downloaded from its website.
The series covers: Stem Canker, Soybean Seedling Diseases, Pod and Stem Blight and Phomopsis Seed Decay, Soybean Vein Necrosis Virus, Charcoal Rot and White Mold.
The series will be updated regularly with the latest available information on diseases and management options, said Kiersten Wise, Purdue Extension plant pathologist.
"We are entering the time of the season when symptoms of many soybean diseases begin to emerge," she said. "With the wet conditions we had earlier in the year, we may see more soybean disease issues in 2015, and it is important that farmers know what is going on in their fields."
Wise said the project began in 2013 with the outbreak of Soybean Vein Necrosis Virus.
"This was a new disease in many states and we realized that there was very little information available to provide to farmers about this disease," she said. "This group compiled what was already known about the disease into a publication that we were able to make available to farmers to answer their questions about SVNV before the next growing season."
In 2014, stem canker and pod and stem blight were more prevalent in Midwestern soybean fields, and the group developed several publications to address those diseases.
Experts from the participating institutions stay in regular contact and develop resources on different emerging diseases each year, Wise said.
The group has also used recent research to update past publications on common diseases such as white mold and charcoal rot, and soybean seedling blights. All Extension plant pathologists in the North Central region review the publications prior to release.
"These publications create awareness about soybean diseases, and are easily updated as we learn more about these diseases," Wise said. "If farmers are aware of and able to accurately identify the diseases in their fields, then we can take steps to better manage those issues the next time the field is planted to soybeans."
Scouting cards are available for common soybean seed diseases, soybean stem diseases and white mold in soybeans.
The project is supported by soybean checkoff funds provided by of the North Central Soybean Research Program and the United Soybean Board.
For farmers to maximize soybean yields, they need to maximize their management. Often soybean management takes a backseat to corn, but it doesn't have to. Download our free report, Boost Your Soybean Yield, for a one-stop look at ways you can better manage your crop.
