SpeedZone Broadleaf Herbicide for Turf - Gallon - Questions & Answers

You can use Speedzone on hybrid Bermuda.  However, you should not apply it if the grass is stressed for any reason or if it is stressed from drought.  You should also not apply it in temperatures over 90 degrees.  Speedzone can cause the hybrid bermuda to yellow temporarily if you apply it while stressed.

We cannot answer your question without more information.  Mixing instructions depend on what type of grass you have, how large of an area, and what type of weeds you are treating.  All of the mixing instructions are on the product label.  Just look on the label for the type of grass that you have and then it will tell you how much to mix per 1000 square feet based on the weeds you are treating.
