You could mix Q4 Plus Turf Herbicide with another selective post-emergent labeled for use on your specific turf to target Poa Annua. You would want to follow the most restrictive product label, and it is advisable to do a small tank or jar test prior, to make sure the mixture is stable before attempting a full tank application. Additionally, unless you are in a southern most state where the temperatures are well over 50 degrees, this would not be an appropriate time for this application. Please refer to our Lawn Care Schedule for the ideal time to apply post-emergent herbicides to your specific lawn type.
