POA and windmill grass are taking over buffalo/gramma grass lawn - looking for best treatment
Using Tenacity to spot treat windmill grass but seeing a large assortment of wide bladed grasses as well as POA in 3 year old stand. Revolver quite expensive for my size lawn but not liking the idea of Roundup the entire lawn after frost.
Answer:
Revolver Herbicide is labeled to control poa annua, other cool season grasses and a handful of broadleaf weeds but it is not labeled to control windmill grass and can only be used by a licensed professional. At this time, Tenacity Herbicide is the only herbicide labeled to control windmill grass and buffalograss is labeled to be tolerant to it.
