Corn and soybean producers are being urged to intensify field scouting immediately. Agronomists across multiple regions have confirmed early cases of southern rust in corn and white mold (Sclerotinia stem rot) in soybeans, developing nearly a full month earlier than normal. Warm, humid conditions are creating the perfect environment for these diseases to spread quickly across key areas of the Midwest, Southeast, and Mid-Atlantic.

This early emergence poses serious risks. Southern rust can rapidly reduce leaf area, limiting kernel fill and causing significant yield loss. In soybeans, white mold can infect stems and pods, potentially killing entire plants and drastically cutting yields if untreated.

There are also serious economic consequences. Delayed detection or mismanagement could increase fungicide costs, reduce profit margins, and trigger higher crop insurance claims. Experts recommend scouting at least every 7 to 10 days, especially after periods of humidity and cloud cover.

Precision agriculture tools are proving invaluable under these conditions. Technologies like satellite imagery, drones, and in-field sensors can detect early stress indicators, helping target fungicide applications more precisely and efficiently.

Agronomists also stress the importance of rotating fungicide modes of action to prevent resistance, and of using local extension updates for real-time disease risk alerts. Cultural practices-such as increased row spacing and careful irrigation scheduling-can also help reduce canopy moisture and disease risk.

The next several days will be critical. With both diseases arriving early, growers must act fast. Timely scouting, integrated disease management, and smart use of precision tools can protect yields and preserve profitability in what's already shaping up to be a challenging season.
