Certainty question. Would it be effective fall/early winter when annual bluegrass pops?

I saw the information about soil temps needing to be 55 or above but didn't know if air temps were a factor as well. Thanks

Answer:

According to the product label for Certainty Herbicide - 1.25 oz.: Best results are obtained when poa annua is in the early state of growth and prior to tillering.
