Hi Yield KillzAll Kills Everything Green And Growing. Kills weeds, grass, flowers and anything else that is green that it touches. Does not kill anything brown. So, you can spray it on poison ivy growing up a tree and kill the poison ivy, but not the tree, as long as you don't get it on the green tree leaves. Does not spoil the soil. You can plant seeds or plants right after spraying. It's best to wait a week to be sure you didn't miss any spots, but, there is no required wait time. Stronger than other national brands. Active ingredient: Glyphosate. Ready to use formula. Just point and spray. 24 Oz.
