Corn Grain Quality Concerns Mount as Wet Weather Persists

Corn grain quality is under threat due to variable and wet weather conditions across the Corn Belt and Southern Plains. Farmers are reporting mold, ear rot, and kernel sprouting in their fields, which could worsen with continued rain and heat.

Agronomists warn that the persistent wet pattern will exacerbate corn ear quality issues, particularly in areas where crops have already shown signs of damage. In Kansas, ear rot and ear mold are primary concerns, with Fusarium ear rot and Aspergillus ear mold being the most prevalent.

Farmers are advised to scout their fields before harvest to identify grain quality concerns early on, allowing them to adjust harvest priorities and segregate affected grain if necessary. Ear molds can lower corn test weights and contribute to higher grain moisture, making it essential for farmers to quickly dry grain to 15% moisture or less.
