It has been a while since I posted a corn and soybean disease update for Wisconsin in 2021, and that is because it has been reasonably quiet in the disease world up to this point. However, recent scouting and incoming reports indicate that this could change a bit as we move into August. Let’s take a look at what has happened so far this season and what to keep an eye out for over the next month or so.
Two more counties added in Wisconsin just today. Getting pretty late to spray for tar spot, but scout and keep an eye on things especially if harvesting for silage! https://corn.ipmpipe.org/tarspot/
