This means you would mix somewhere between 0.25 oz and 1 oz at the highest rate per 25 gallons of water, if that 25 gallons covers 1 acre.

It is recommended to spot treat areas of bermudagrass with a glyphosate herbicide such as Roundup and then reseeding/resodding any bare spots after 2 weeks.
Do not make applications in Spring if your turfgrass is transitioning in or out of dormacy. Allow for complete green up and apply in Summer, Fall and Winter only.
