I've been fighting with wild violets for about three years, tried a bunch of different products. Sometimes I'd knock them back a bit, and sometimes I'd knock the grass back a bit, but overall it was getting worse each year. This stuff works!! My only disappointment is that the violets were dead within a week; I would rather they had died a slow painful death, screaming for their mommies like little girls :) I used a pump sprayer. In 2 gallons of water I put 3 tbs Hi-Yield and 2 tbs surfactant. I sprayed just until the weeds were wet. I didn't use that blue marking dye but next time I'm going to try it. With so many violets it got hard to keep track of where I sprayed, and I missed some. Between the ones that I missed and the new ones that popped up since I sprayed, I'm going to have to do a second round. But at least now I'm winning the war. Die, you violets, die, die, die!!

Here is the thing it is 1 TBSP per gallon per the supplemental documents, which is 3 TSP = 1 TBSP. Get yourself a medicine measure from an old cough syrup bottle and dedicate it to herbicides (NEVER use it again for medicines or anything else). I used 1.5 (1 and a half) teaspoons and mixed it up in a dedicated sprayer with half a gallon of distilled water (it is free of all contaminants). From there I added 1 teaspoon of non-ionic surfactant for herbicides (because the product I used recommends 2 TSP/ gallon and I mixed up half a gallon.) Lastly, a blue dye that recommends 1oz per gallon. Two tablespoons is an ounce; hence one (1) tablespoon was what I used for half a gallon... In a gallon sprayer I put a nozzle on it that atomizes the spray and pumped to high pressure. Worked great completely curing my lawn of creeping vine Charlie and surges. I have Centipede grass which is a riskyer lawn to use this on per the instructions, but I had no lawn damage whatsoever on my TiffBlair type Centipede warm-season grass in West Columbia, SC. Your results may of course vary from mine which was 100% elimination of the weeds with no lawn damage, but I think most critical is the instructions by the manufacturer realizing that this small bottle is a potent product not forgiving in that you must measure accurately in teaspoons per gallon unlike diluted homeowner products. Alway wear the appropriate PPE and do a test spot to verify you have things dialed in.

Nothing I have tried previously has worked on these things; Trimec, 2-4D, some others I can't spell :) A few days after application I was weary that this wouldn't work either, but after a week there was noticeable change. Looks like this did the trick!
