Yes, Q4 Plus Turf Herbicide can be applied at the same time as 21-0-7 fertilizer. As always be sure you are applying these products during the cooler times of the day when temps are below 85 degrees.
We would suggest doing a compatibility test before tank mixinging Q4 Plus Turf Herbicide & Fusilade Herbicide together. Using a small jar, mix both products according the tank mixing instructions on the more restrictive labeling of the two (Fusilade II product label) and look for separation and clumping.
Fusilade II is labeled to be used on Zoysiagrass but states it is not for use on home lawns. Q4 is labeled to control both bermudagrass and zoysiagrass and temporary discoloration should be expected and a test application should be done and wait 30 days before treating the entire yard. We recommend reviewing the Bermudagrass and Zoysiagrass Advisements in Table 3 on the Q4 product label.
Q4 Plus Turf Herbicide is not labeled to be used over groundcovers or monkey grass so would not be recommended. Depending on what you are treating for, a better option would be Fertilome Over the Top II. It is labeled to kill grassy weeds in lirope and various other ornamentals and ground covers.
We do not recommend applying Q4 Plus Turf Herbicide to buffalograss since there is no mention of tolerability on the product label. We would recommend contacting your local cooperative extension office to see what you can use in your desired turf to kill buffalograss.

Q4 Plus Turf Herbicide does not list spurweed on the label as a weed it controls, so we cannot recommend a rate.
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.
