Emater/RS-Ascar reports summer corn planting in Rio Grande do Sul has reached 80% of the 896.4 thousand hectares planned for 2026/27. Excess rain, cold temperatures and low sunlight have slowed operations and caused uneven early growth, stand failures and some replanting.
Delayed and uneven planting in a key southern Brazilian state could trim local corn output and modestly support feed corn prices if losses widen.
After 1,465 past bullish weather events, CORN moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
