Most wheat across the state has reached or is entering flowering. Dry conditions accelerated development in many fields, resulting in earlier heading, shorter plants, and somewhat reduced head size. Rainfall over the weekend was much needed but uneven. The Eastern Shore received up to ~0.75 inches, while parts of the Middle Peninsula and Northern Neck received only ~0.25 inches.

A freeze event about one week ago is now beginning to show symptoms in some fields. Growers should scout approximately 7 days after the freeze to distinguish head bleaching caused by freeze injury from symptoms that may develop later due to Fusarium head blight (scab).

The current FHB risk is moderate, with additional rain in the forecast. The highest risk fields are those planted into corn stubble with susceptible varieties. With variable yield potential and recent weather patterns, fungicide decisions should be made on a field-by-field basis, prioritizing fields with strong yield potential or contractual obligations. Fungicide applications are most effective when applied at early flowering (Feekes 10.5.1).
