Donnellson, IA. Makes saying here easier. | Another thing I would consider is the extreme variability in our rainfall events in lee county this spring. I've had .2" at my shop and less than 1/4 up the road 1.5"'s.
If it has worked well for awhile then it's time to switch it up. Unfortunately we like to stick with programs long enough the weeds become as home with them as we do.
I like the group 2 component of your pre for part of our weed spectrum. But I prefer a yellow(prowl h20 in notill) or a group 15 for waterhemp suppression. I've never had the results that many do with authority. Honestly with the last few spings being what they have been, a fall spray or very early burndown with a residual pass chasing the planter might make more sense here.
