Did some test plots in west mi and found that drive actually worked on crab a little better than q4 plus. both were full rate with a spreader sticker. I decided to sit down and figure out how much quinclorac was getting down at full rate on each and am kind of stuck. q4 is a liquid ounce and drive is a weighted ounce and am having a hard time coming up with a way to covert and figure out if drive was putting more quin down than q4. Might as well throw solitaire in the comparison too, I've heard people have been pretty happy with the results. Any ideas?
