Some of the winter wheat in SD is past flowering growth stage. This means the risk for Fusarium head blight is low. Moreover, current FHB prediction tool shows low risk for the entire state. This is mainly due to the dry weather we have had the past few weeks. Although rains came through the last two days, we need to accumulate several days of favorable weather for the FHB risk to change. Late planted winter wheat that has not flowered yet may still be at risk. Keep watching the weather and the FHB prediction tool until wheat is done flowering.
