As long as you are following the product label instructions for the products you are using, your turf should not be injured. Kinetic is just a surfactant and should not kill anything at all. Kinetic is usually added to herbicides, pesticides or fungicides to help the products better stick to plants and other vegetation. We do carry a full line of herbicides if you need to purchase an herbicide. You can read the product label of any herbicide you choose to make sure your species of grass is listed as a tolerant variety. Product label links are available on individual product pages under the "Product Documents" section.
