Is now a good time for farmers to prioritize weather-resistant hybrid seeds for their crops?
September 2026 was the wettest month in Iowa in roughly 112 years. The excessive precipitation caused widespread grain sprouting in fields, a condition that threatens overall grain quality and market value.
Why it matters
The moisture levels have created significant quality concerns, as sprouted grain often commands lower prices and may complicate storage and processing for agricultural businesses. Operators are now assessing the extent of damage to inventory that was expected to reach standard maturity.
September 2026 was the wettest month in Iowa in 112 years. The damage is most acute in southwest Iowa, though the total scale of lost market value is still being assessed.
The players
Landus Cooperative

The details
Sprouting in corn fields is being linked to specific hybrid traits, particularly those with vertical ears that retain more water. In soybean fields, insect damage has been identified as a primary contributor to the increased likelihood of pre-harvest sprouting. This combination of factors has accelerated deterioration in field conditions across the state, particularly in southwest Iowa.

Market Landscape
This record-breaking moisture event serves as a sharp reminder of the volatility inherent in regional agricultural cycles. It follows a pattern of localized environmental impacts that complicate standard yield projections and shift immediate commodity quality assessments.
Producers should prioritize inspecting fields for sprout prevalence to determine harvesting order and storage strategy. Owners should consult their agronomists to assess how specific hybrid traits on their property are interacting with current moisture levels.
The takeaway
Grain sprouting significantly impairs marketability and requires an immediate adjustment to storage and sale plans. Operators should monitor the condition of their specific hybrids and contact their local agronomist for guidance on minimizing further quality degradation.
