Many people have asked about the need to make a fungicide application for frogeye leaf spot on soybeans this season. I have posted a new article on the Illinois Field Crop Disease Blog which reviews this pathogen, how it works, and some new tools that may help you with these important decisions.

The University of Illinois Extension will host the Ewing Demonstration Center Agronomy Field Day on Thursday, July 26, 2018 at 9 a.m. Every growing season presents challenges to production, and this year is no exception! We are happy to host this summer field day to share with local growers current, ongoing agronomy research in southern Illinois, including cover crop trials on corn and soybeans, nitrogen management in corn, weed management in soybean, and our continuous no-till field,…
Today we received reports of Tar spot appearing in corn grown in Illinois. We are currently studying tar spot of corn in the United States, and are requesting that any CCA, producer, or ag professional that encounters this disease, even if outside of Illinois, please send samples to Diane Plewa at the University of Illinois Plant Diagnostic Clinic.

Every year we hear about fungicides, and their utility in agronomic production systems. Indeed, these products can be an extremely useful tool to prevent yield-related losses resulting from fungal diseases. However, reduced commodity prices are making it crucial for producers to minimize inputs in order to maximize profits. …
With the storm that moved through the state the past week, it is not surprising that we are seeing more seedling diseases in soybeans. In many cases Rhizoctonia has been identified as the causative organism, alone or in combination with other soil issues such as compaction. Rhizoctonia is one of the most common and problematic seedling issues for soybean producers in Illinois, and can cause significant yield losses due to stand reduction and reduced plant growth. …
Now is the time that seedling diseases of soybeans will start to be apparent. Indeed, we have started to see more images of soybeans that may have symptoms of seedling disease. However, it is important to understand that seedling diseases are complex, and a simple picture often is not sufficient to adequately diagnose the issue. I wrote a more extensive of seedling diseases of soybean on the Illinois Field Crop Disease Blog, which can be accessed here…
