Hopefully you will get the root and not just a burn down. I had a lot of that burn no kill early this year and those little patches were driving me crazy as they popped back up.

Maybe you are not getting good coverage. Driving too fast?
The rate for Super Trimec is .75 to 1.1 or 2 to 3 pints per acre. (32 to 48 ounces per acre).
The cost is in the labor. Why kill some of the weeds? Kill'em all.

You said you are making 2 passes. What spray tip are you using? Are you mixing at half the rate of the high end mix rate?

clover killer

Here is a quick test of clover sprayed with Speedzone plus Drive. Notice in the center of the round spot--the clover is dead. Speedzone by itself is also excellent. A surfactant was included at about 1.5 percent.

Looks like you are applying 0.72 oz/M Super Trimec, which is just under the low end of the label rate of 0.75, if I understand your post correctly. You may need to bump Super Trimec to 30 oz for your setup. This will get you very close to the high end of the label rate of 1.1 oz/M.

Riggle makes a good point about nitrogen. I always fertilize 5-7 days before I spray for broadleaf weeds. That is not practical for people knocking out large numbers of yards, I realize. Take a look at annual N totals on your most difficult lawns. It may pay to add another 1/2# N in late May or a September.

Good luck.

Did that scorch the turf a bit or is it just the pic? Isn't drive more of a crabgrass killer? I always equated Drive to Quinclorac- am I off on that?

Correct, Drive (quinclorac) is more of a crabgrass killer, but--it also kills some types of weeds. Perhaps not permitted in New York.
So true, Speedzone at 6 times the proper rate will injure the grass. See my test from 6 weeks ago.

But where I used Drive and Quicksilver at 3 times label rate each--there was only slight injury. I think at label rate for Speeedzone you should be fine. If you look carefully at the clover picture, I think you can see green grass blades growing up through the dead clover. Surfactant was included.
