We continue in a pattern of high humidity that will favor FHB this week. Much wheat in the south has flowered over the last 7-10 days, and wheat in the central part of the state will likely enter flowering this week, especially if temperatures hit the 80's as forecast. If you are entering flowering this week, continue to monitor the FHB prediction center and forecast. Remember that fungicide applications of Caramba, Prosaro, Proline, and Miravis Ace applied from Feekes 10.5.1 (when approx. 50% of MAIN tillers start to flower) through 5-6 days from the start of this point provide the greatest efficacy for suppressing FHB. Follow all label guidelines.
