Wheat in southern Indiana has started to head out and will probably start flowering (Feekes 10.5.1) in the next week. Currently the six day forecast for FHB is low for most of the state, but rain is predicted again next week. In central Indiana our wheat is at flag leaf (Feekes 9).

Wheat will be susceptible to FHB infection as it moves into early anthesis through full flower. A fungicide application may provide protection during this critical time. The updated wheat fungicide efficacy guide is a resource that can provide guidance on fungicide choice for efficacy against FHB and other diseases. It is available on the Crop Protection Network at https://cropprotectionnetwork.org/publications/fungicide-efficacy-for-c…. Continue to monitor the risk as weather changes over the next few weeks to see what happens as the rest of the state moves into that critical time period.
