Can I use Speedzone Red on Tiff green Hybrid bermuda grass lawns?
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.
