Following last week's rain, the risk for Fusarium head blight (FHB)
infections has increased, and the risk is very high even for moderately
resistant varieties in certain portions of the state. Much of the wheat crop
is beyond the early flowering stage, but for fields where wheat is currently
flowering a fungicide may be needed to protect the crop from FHB infection
and DON contamination. Recommended fungicides include Caramba, Prosaro, and
Proline. Fungicides are most effective when applied at the start of
flowering and up to a week later. The greatest coverage of the heads can be
achieved by applying fungicides in 5 gal/A by air and 15 gal/A by ground
with a 300-350 um droplet size and nozzles angled forward at least 30
degrees.
