Fusarium Head Blight Risk Update-April 22, 2019

— Written By

This is the third update on Fusarium Head Blight (FHB) risk in North Carolina in 2019. More information on FHB and symptoms can be found at the Small Grains Extension portal.

Current Risk

Wheat and barley that is flowering today is a medium to high scab risk in widespread, but scattered, regions of the central Tidewater zone. Late-planted fields may not yet be near flowering. Fungicides are less effective when applied prior to flowering, and should be applied at early flowering. If necessary, spraying up to 6-7 days after early flowering should be nearly as effective. Do not apply a strobilurin-containing fungicide after flag leaf stage. The most effective products for FHB are Caramba, Prosaro, Miravis Ace, and Proline.
