Michigan grain merchandisers reported some of the highest vomitoxin levels in 2023 corn, following a Gibberella ear rot outbreak linked to wet conditions. Elevators are discounting corn and delaying deliveries while testing, and at least one feed mill is paying a premium for low-vomitoxin distillers grains.
Mycotoxin contamination limits corn usable for feed, shifting demand toward soybean meal and boosting premiums for clean DDGS, which affects regional feed formulation costs.
After 175 past bearish disease events, Corn moved a median +0.0% over 5 sessions (51% higher; middle half -1.7% to +1.5%), and +0.6% over 20.
Not enough comparable past events yet for a historical read.
After 67 past bullish disease events, Soybean Meal moved a median -0.2% over 5 sessions (46% higher; middle half -1.7% to +1.9%), and +0.4% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
