Q.Nimble will and Tenacity
Can I apply Tenacity to the dead brown grass areas now? The grass is lying horizontal. Already did one app 6-10. Also I may have bentgrass but can’t tell -This time of year? I live in Syracuse NY. Can I reseed right away with perennial ryegrass? Help? Thanks

According to their description, it will control weeds at seeding and allow the new grass to flourish. I would check the label, though, to make sure perennial ryegrass is not listed as one of the plants it controls. It does control nimblewill and bentgrass.
