Wheat scab risk elevated in northeast North CarolinaWheat scab risk elevated in northeast North Carolina

Wheat crops that are flowering now in northeast North Carolina are at moderate risk of scab. Much of the crop there has already flowered and is past danger, but some fields are flowering now or will flower in the next two weeks and are at risk.

It will pay to spray if the variety is susceptible or moderately susceptible, and possibly if it is moderately resistant. Apply a fungicide at early flowering or up to seven days later.

Do not apply a strobilurin-containing fungicide. The most effective products are Caramba, Prosaro, and Proline.

Information on wheat fungicide efficacy can be found here. 

Aerial application may be profitable.

For ground application, rear- and forward-facing nozzles should be angled down 30 degrees from horizontal. For more details on wheat scab risk predictions, go to the FHB Risk Assessment Tool at http://www.wheatscab.psu.edu.
