Tenacity, also know as Callisto works well. Best success is in late fall, 2 or more applications. Play around with rates to find what is best for you. Good thing is that bluegrass is very, very tolerant of product. Nice thing about a late fall rate is you pick up control of chickweed and other broad leafs. This saves you an early spring Trimec type of application.

Tenacity has pre/post control at time of seed apply 8 oz. of product per acre to control annual grass weeds & a wide range of broadleaf weeds as well. For post control best results are after soil temps are between 45 - 50 F. Apply 8 oz. 2 to 3 times 10 days apart for best control.

Do not apply on creeping bentgrass unless you are trying to remove it out of Kentucky Bluegrass.
