Due to the recent rain, scab risk is increasing in portions of Virginia,
especially on the Eastern Shore and coastal areas. Many fields are at or
near flowering. In most areas, moderately resistant (MR) varieties are in
the low to medium risk category, but keep in mind that many acres are still
planted to moderately susceptible (MS) or susceptible (S) varieties such as
Shirley. In the eastern portions of the state, scab risk is projected to be
high for susceptible varieties over the next week, and it will likely be
necessary to work in fungicide applications between rain events. Do NOT
apply a strobilurin or fungicide pre-mix containing a strobilurin after
heading 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.
