Due to the recent rain, scab risk is increasing in portions of Virginia,
especially on the Eastern Shore and coastal areas. Fungicides targeting scab
should be applied within 5-6 days of flowering (50% of main tillers starting
to flower from the center of the head). Do NOT apply a strobilurin or
fungicide pre-mix containing a strobilurin after flag leaf emergence (Feekes
9) since this can increase DON contamination in the grain. Prosaro, Caramba,
and Proline are the most effective products for reducing scab and DON
contamination. These fungicides will also control foliar diseases such as
leaf blotch, stripe and leaf rust, and powdery mildew.
