As we approach time for a herbice application also make sure to monitor for rust. This is a picture I took today of stripe rust in a winter wheat field in Hand County. Seeing rust this early in the season makes a fungicide application a must. Strobilurin fungicides are very effective. Yield losses can be substantial if rust isn't controlled. With rust showing up this early keep track of which product you use. If you need to make a subsequent flag leaf application again for rust its a good idea to use a different product to manage for efficacy and resistance.
