FHB Update from IL, 06/03/19

Much of the wheat has flowered in the S and Central parts of IL. Expect late flowering wheat in the N most parts of IL to flower within the next 7-10 days. Over that period of time additional rains are forecast, which may slightly elevate risk levels. Wheat that flowered approximately 3 weeks ago should be showing symptoms of disease if infections occurred.

Remember to switch the model to best approximate the resistance level of your varieties. The map defaults to susceptible, but your risk will change substantially if you planted moderately resistant or even moderately susceptible varieties.
