How much Grass Out Max should I use per gallon of water to control poa annua?

I would like to kill poa annua in my Bermuda grass lawn.


Grass Out Max (Clethodim Herbicide) can eradicate Bermuda and Poa Annua. Revolver Herbicide is a post-emergent herbicide that is labeled to kill poa annua in Bermudagrass. Be sure to apply this product in temperatures above 60 degrees Fahrenheit. The mixing ratio is 0.2-0.4 fl. oz. per 1000 square feet. This will generally mix in a gallon of water.
