Bonide and Hy-Yield are two brands that pop into my head off-hand.
Go to a Garden store, Farm store or hardware store as they should have some brand in stock.
If you have one I would start with the farm store.
Before you apply cut your grass as short as your lawn mower will allow it will work better usually, at least it has for me.
Crab grass is annual so getting the seeds onto the ground where the killer/preventer can hit them is better than if they are dangling in the air on a branch but they sprout as long as their is war weather.
