Will this act as a pre-emergent for Fescue or only selectively for poa annua, crabgrass, etc? I'm looking for something to control poa annua during fall fescue seeding.
Bensumec 4LF Herbicide states on the product label: Any material that provides effective control of annual grasses may affect new lawn grass seedlings which germinate after treatment. Do not reseed within 4 months after application. The only product that can be applied as a pre-emergent around the same time as seeding Fescue is the Tenacity which is labeled to suppress poa annua as a pre-emergent and can prevent crabgrass.
