Corteva Agriscience reports that a wet spring and dry summer in 2024 hurt weed control and timely postemergence herbicide application. Corn yields were described as phenomenal, while soybeans were only average without August rain, and corn faced tar spot, northern leaf blight and gray leaf spot.
Strong corn yields add supply and ease corn feed prices, while weaker soybean yields tighten the soy supply that feeds the soybean meal market.
After 357 past bearish weather events, Corn moved a median -0.3% over 5 sessions (44% higher; middle half -2.2% to +1.3%), and -0.5% over 20.
After 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
