Bought some tenacity from you and spot sprayed on my crabgrass. It has been white for about a week and seems to be dying. My question is, will it just disappear on its own once dead, or will I need to pull or rake the dead stuff eventually?
No, We would not recommend pulling up any weeds because the product will not get into the root system, and the weeds may come back at that point. After spraying with Tenacity Herbicide, the foliage of treated weeds cease growth after application, then turn white(loss of chlorophyll), and death may take up to three weeks. A repeat application is required after two to three weeks for improved postemergence weed control.
