I've been doing what your planning for 8 years,except I use Bicep 2 mag.
I've had to start adding 4oz. of Banvel to the mix to help with giant ragweed and marestail. I think some of our ragweed is roundup and callisto resistant (or tolerant at least).
It's just ragweed. It was hard to kill with just roundup 15+ years ago. Don't think it's resistant it's just a tough weed. Stalk bore makes it worse. |
