Head Scab Risk Rises For PIedmont plus Chowan and Wayne Counties

Head Scab Risk is now medium to high in southern counties of the NC Piedmont. Risk has also increased to moderate in a small area near the Albermarle Sound (Chowan Co.) and in Wayne Co. Rain forecast for the next few days suggests the risk will remain elevated in some parts of the state. You may wish to apply a fungicide specifically for head scab reduction, in the next 10 days, if:

1) you are in the southern Piedmont or Albemarle Sound counties, and

2) as of today, the wheat growth stage is between start of heading, and full flower. (If a spray at the best timing of mid-flower is not possible, research shows that applications up to 5 to 6 days later can still be beneficial for head scab reduction.)

The most effective fungicides against head scab are Prosaro, Caramba, and Proline. Do not apply a strobilurin or a strobilurin-triazole mix.
