I have resistant poa in Tiff Dwarf greens 20 years old
Ronstar G Herbicide is applied at 2-1/4 lbs per 1000 sq ft for poa annua in a Bermuda lawn. The label states to apply in the late summer or early fall prior to seed germination of the poa annua. If you were to apply to established poa annua it will not be controlled.
