Ok then. Spot sprayed with 4oz to a gallon today. I'll report back in a few.

Thanks everyone for the replies.


Good luck. Should work well on surface mat spot spraying. It doesn't make much difference how strong you mix it because the water is just a carrier for the active ingredient. IOW, a heavy spray of a weak mixture will work the same as a light spray of a heavier mix. My problem with mixing it too heavy is that I tend to use too much and run out of spray before I cover the intended area. By mixing it lighter I can cover the area and then turn around and respray heavy areas if I have some left. But that is just me and my ineptness showing.
