The fungal disease has spread to fields in at least seven states since 2018, including three new ones just this year. Once established, the pathogen is nearly impossible to eradicate, Extension plant pathologists report.
Number of bushels per acre is high on their list of priorities, but it’s not necessarily their No. 1 concern going into 2026.



As crops go into bins, growers will be looking to maintain quality until their marketing opportunities improve. Some ongoing management practices are vital to the process.
While many farmers in the state were delighted by the results the 2025 season delivered, that wasn’t the case everywhere. In some areas, Mother Nature delivered a series of agronomic problems that dominoed and turned a potential bin buster crop into one that was average at best by harvest.
Agronomists answer farmer questions about the role of nitrogen and other nutrients in lessening the potential impact of yield robbers such as southern rust and tar spot in corn.
Corn yield champs say annual soil testing is the best way to make sure fields are up to the goal of delivering profitable high yields every season.
The new product also addresses other key issues in soybeans like frogeye leaf spot and septoria brown spot.
With low commodity prices and higher input costs, identifying hybrids that are a good fit for your soil types and environmental conditions is more important than ever – and can give you a leg up on yield performance from the get-go next spring.
With contributing factors ranging from insect pressure to disease and environmental stressors this season, agronomists say farmers face hard decisions on when to combine their crop in affected fields.
Herbicides and defoliants are commonly used by farmers in southern regions to quicken the harvest period and reduce the risk of shatter loss and poor test weights. Now, Midwest growers and researchers are looking at how to use the practice.
