Can Q4 be applyed when temp is 75 degrees but will reach 90 degrees later?
Also, can Q4 be applied on established Empire and Meyers Zoysia?
Q4 Plus Turf Herbicide can be applied in the morning or in evening when temps are below 85 degrees. If there is enough time for the product to dry before it hits the 90's it should stil be effective. When applied as directed it will not harm your Zoysia lawn. Since you mentioned Empire and Meyers Zoysia, you may want to make your application when Temps are staying out of the 90's.
