    I have finally found a product effective on wild violets. This is a tremendous product and PedChem is great to buy from.

    First time user

    I read quite a lot about this product and the wide range of concentrations that are used. I decided to start with two ounces per gallon to make sure my lawn tolerated it. I'm about 5 days out and the wild violets, chickweed, and clover (the prominent weeds in my lawn) are all showing signs of distress. So I would say it's looking promising. I have a small front yard and a large backyard, so I chose to start in the front and see how it worked. Looks like I'll be taking on the backyard soon. It looks like I'll probably need to dial up the concentration to fully eradicate the weeds.

    Great product

    Works well. We get a lot of wild violet (heart shaped leaves, purple flower) and this is the only stuff I’ve found that kills it. Reasonably priced and ships quick. Sellers are responsive when I’ve contacted them. Will buy more from them in the future when I need it.

    Great Product! Gets rid of wild violets!

    I have used two other brands of herbicide **** killer purchased from our local stores. Neither of them would completely **** the wild violets from our lawn. 4-speed XT completely killed the wild violets in addition to the other weeds in our lawn. We are well satisfied with this great product.
