I guess I am stuck until next year then, using a pre-emergent? It is the
entire backyard of a new house, plant by plant is way to much. The
builder
let it get wild and also seeded bluegrass and fescue. I hate to till the
whole thing and start over, it's about a 1/4 of an acre. I was hoping
something was out there to get the crabgrass.

The type of grass you have does not tolerate a selective crabgrass herbicide
like CSMA or MSMA. Pre-emergent is your best bet. Crabgrass is an annual
and has to come back by seed.
