I live in Mesa, Arizona, and have tiffgreen. Will Speedzone kill my lawn?

4 weeks ago I spot treated with Spurge Power and Spots are still yellow and no signs of grass coming back.


SpeedZone Lawn Weed Killer Concentrate is tolerable on most common and hybrid bermudagrass such as Tifgrass. Temporary turfgrass yellowing may occur on certain varieties (F1 hybrids) of hybrid bermudagrass. To reduce risk of lawn injury, avoid spraying drought stressed lawns or when temperatures are above 85°F. Please read the product label for complete mixing and use instruction prior to using.
