In this week's CropCast, hosts Seth Naeve and David Nicolai welcome Dr. Dean Malvick, University of Minnesota Extension Plant Pathologist for corn and soybeans. Dr. Malvick dives into the 2025 growing season to discuss the development and yield impact of key crop diseases. He provides a timely review of Southern Corn Rust and Corn Tar Spot disease biology, detailing their spread across Minnesota and adjoining states this year. Dean also outlines the knowns and unknowns regarding the progression of these corn diseases in relation to weather, wind, and crop rotation. Finally, the discussion covers the complex management strategies, including hybrid selection and the critical timing of foliar fungicides. We didn’t forget to ask about soybeans. Dean touches on the widespread presence of White Mold in Minnesota fields and the discovery of Red Cown Rot.

Ed Usset, Grain Marketing Economist at the Center for Farm Financial Management, University of Minnesota, joins us for this milestone 50th episode of Minnesota CropCast, recorded on September 12, 2025.

Working with colleagues at the Center for Farm Financial Management and in Extension, Ed developed the acclaimed Winning the Game workshop series and manages Commodity Challenge, an online marketing education game that uses real-time cash and futures data. At the University, he also teaches Commodity Markets to undergraduate and graduate students.

In this episode, Ed stresses the economic importance for grain growers to complete final marketing of any 2024 crop still in storage by this fall. He shares suggestions and target prices to help producers forward-price grain, drawing on seasonal post-harvest market patterns—especially critical during times of lower prices and weakened demand under current trade policies. He also reviews the potential financial impacts of economic constraints on U.S. feed grain exports, particularly corn in 2025.

Finally, Seth Naeve, University of Minnesota Soybean Extension Specialist, discusses soybean export needs across Asian markets and what shifting demand means for Upper Midwest producers.

In 1960, the number of farmers raising dry beans in Minnesota and North Dakota could be counted in single digits. The 2025 USDA Dry Bean Planting report showed 320,000 acres (22% of US production) in Minnesota and 630,000 acres (43% of US production) in North Dakota, thus placing Minnesota in 2nd place in US production ahead of Michigan and several other states. In this episode Dave Nicolai and Seth Naeve chat with Minnesota Independent Crop Consultant, Darrol Ike and Mitch Coulter, Northarvest Bean Growers Association Executive Director, about the production and market expansion of dry beans in Minnesota.

Farmers in the Northarvest (Minnesota and North Dakota) region grow a wide range of dry bean types including pinto, navy, black, dark red kidney, light red kidney, white kidney, Great Northern, pink, small red, and cranberry beans. Darrol reviewes some best management practices of successful dry bean growers concerning planting dates, populations, weed control and crop inputs. Mitch Coulter discusses dry bean markets, research, uses, exports and the increasing acreage for specific varieties of dry beans. Mitch also comments on legislative efforts to improve the usage and production of dry beans.
