Looking for something that will kill grassy weeds & crabgrass but also can be applied when overseeding that won't hurt new seeds.
Tenacity is typically the choice for a pre-emergent herbicide needed when seeding or overseeding a lawn, particular tall fescue or other cool-season grasses. For QuinKill Max, you will need to consult the chart on pages 15-16 of the product label for appropriate timing depending on the type of turfgrass. Some grasses are more tolerant of this herbicide than others.
