Recommendation for dilution of selective herbicide chems

[Nelly Wensdow]

I want to use up this old bottle of Spectracide's Weed Stop for Lawns, but unfortunately the label is all kinds of gone. And that's beside the fact that I really don't want to just spray it all the hell over the lawn, I'd rather just spot-treat these horrible thistles that're just about everywhere. Anything left over's going onto the dandelions. I don't want to be bothered with sending it to the local Clean Sweep crew, which would cost me more in gasoline to get there & back than it probably did to buy the stupid thing.

This is the kind of product that gets hooked up to the end of a garden faucet.

It contains, roughly :

2,4D 7.6% Mecoprop-p, 2.7% dicamba, 0.71% sulfentrazone, 0.18%

That's if I can believe what I *think* I can see through a 16x loupe looking at the front label. Guess the company didn't particularly want anyone to know what-all was in it?

It was here when I moved in a few years ago. In case it's way expired, is there any more harm in spraying it onto the lawn than if it weren't?

When I spray thistles, I use about 0.5% solution of 2,4D. You could dilute your product quite a bit. I don't know about the other chemicals in your mix. I really doubt this stuff has "expired".

Use one ounce (2 Tbsp) per gallon for spot treating. (or 1.5 tsp per quart)

Hope this helps, Bob

I'd also think 1 to 2 oz. per gallon. Spec for Weed Be Gone which is similar.

my memory must be bad. I think I used a 0.2% solution when spot spraying thistles.

Thanks, all. I think I'll start with the lowest dose, not for the least reason they seem to have changed the formula a bit.
