Winter wheat in New York began flowering this week and much acreage was sprayed with Caramba, Prosaro, or Miravis Ace. There is an application window of approximately 7 days from the beginning of flowering in which reasonable FHB and DON suppression can be expected from these fungicides. The risk of FHB infection in winter wheat has increased in some areas of New York over the last few days. Check the Fusarium Risk Assessment Tool (www.wheatscab.psu.edu) and your local weather forecast frequently as your winter wheat crop approaches flowering.
