your wrong on your percentages......they have almost identical amounts of quinclorac
solitaire/1000 .467 x .5625= .262ai
q4/1000 3oz x .0843= .259ai
my belief is gordons has included mso or some other type of adjuvant that solitaire does not include......
I have tried the seperate spray cans but then it gets annoying having to go over the yard several times with different sprayers because there is always sedges, spurge, and crab in places....theres never just one type of weed
