Preventer, not killer
Assuming you're actually in New Hampshire... The existing crabgrass should die off over the winter, and if this is applied early enough in the spring "it should prevent" germination of new crabgrass. It works to an extent. You'll still get crabgrass, just maybe less? It's a fertilizer too, so there's that, regardless of it's crabgrass eliminating efficiency. I'm trying prodiamine with a general fertilizer next year instead of this

Crabgrass thrives in turf and landscapes with hot, dry, compacted soils. Crabgrass can outcompete many turfgrasses found in lawns due to its ability to thrive in intense heat and sunlight.
Crabgrass moves through stages of its life cycle according to day length. In the spring, once soil temperatures reach approximately 55 degrees, crabgrass seeds begin to germinate. The grass grows throughout the summer until days start to shorten and crabgrass enters its reproductive stage, forming seedheads.
Crabgrass drops its seed and dies by the first frost, returning in the spring."
