The next week is going to be a very busy time for area wheat growers. Although the tap has been turned off for most of the last two months, it looks like Mother Nature is going to share the rain with us just when we don't want it. Warm, humid days with the odd thunderstorm are just the type of weather than Fusarium Head Blight loves. Even without the moisture, some fields are in need of a fungicide application for Stripe Rust control.
Below is the staging guide for Prosaro from Bayer. You want to spray when the majority of the heads begin to show small yellow flowers in the middle of the head. If the flowers have turned grey and falling to the ground, you are too late. Check you fields daily as the wheat can move quickly with the warmth and chance of moisture we are to get.
