Yes. You will want to remove weeds before reseeding. How long it takes Q4 Plus Turf to kill the weed will depend on the health and maturity of the weed. The weeds normally will start to die within one week of application but could take up to three weeks. A second application may be needed.
If a second application of Q4 Plus Turf Herbicide is needed, per the product label, there needs to be at least 30 days between applications but no more than 2 broadcast applications in a year span.
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.

You can apply Q4 Plus Herbicide anytime the target weeds are young and actively growing. This product will not work well in very cold temperatures, so we recommend applying Q4 Plus when air temperatures are around 60-85 degrees for best results. Be sure that your turfgrass is listed as tolerant on the product label.
We do not recommend coming Q4 Plus Herbicide with other post-emergent herbicides such as Triclopyr Ester. The Q4 already contains 4 active ingredients and covers a wide variety of weeds, so adding more active ingredients could damage your desirable turfgrass.
While you can add a surfactant with Hi-Yield Triclopyr Ester, we do not recommend adding it to Q4 Plus since that can increase the risk of injury to your desirable turf.
The mixing ratio of Q4 Plus Turf Herbicide for Fescue is 7- 8 pints per acre (2.6 to 3.0 fl oz/1000 sqft). When broadcasting your water volume may change so while the concentration of product per area is the same as the spot treatment, if your turf is very dense you may need 2-4 gallons of water over 1000 sq/ft, vs the only 1 gallon needed for spot treatments. Please review the product label for more information.
ideally, you would want to aerate and detach the lawn prior applying herbcides to avoid any distrubtion of the herbicide being absorbed into the weeds. You can view our Lawn Care Schedule Guide for more information on timing. Typically, we recommend waiting at least one week after the application of to Q4 Plus Turf Herbicide allow your turf to not become over-stressed by product application.
Please contact the manufacturer of [N-Ext] Air-8 0-0-5 / D-Thatch 0-0-2 Combo product for any timing restrictions.
