Can Q4 and Fusilade II be tank mixed for treating broadleaf weeds and bermudagrass in a Zenith Zoysiagrass lawn? ...

Answer:

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
