I find very little about liquid pre emergent "weed" controls. Lots of hits in a web search but most all then report on post emergent poisons.

I have never understood the hoopla about crabgrass!
It is a ANNUAL, it dies every fall & comes back from seeds.
DO NOT let it go to seed & you have STOPPED the cycle of life for the crabgrass.
My son spent 3 years clearing a small bed of crabgrass, I would wait til it went to seed & tell him.
Next year you will be pulling grass, because you let it go to seed.
It took 36 months, but he learned not to put off till fall what should be done in spring & summer.

Totally wrong time of year for pre-emergents for crabgrass in zone 5, anyway.

Three herbicides come to mind, all liquids in their agricultural formulations. Treflan, Sonalan, and Prowl. To a lesser degree, Eptam might do the job also. Treflan is an ingredient in Preen. Not sure if the others are available for homeowners.

I assume you would be applying them to a lawn. If so, read the labels carefully as Eptam has some activity on some perennial grasses. I would probably look to Treflan (Preen) first, then Sonalan, then the others. I think Preen is a granular, but you can apply it, then water it in with about 1/2" of rainfall or sprinkler irrigation within 24 hours and it will take the herbicide into the ground.
