While Propiconazole 14.3 Fungicide can be tank mixed with many herbicides and other products, we would not recommended applying that many products at once, especially in the summer. The propiconazole being oil based will have more potential to burn or stress the lawn when mixed with a strong herbicide such as Q4 Plus Turf Herbicide and a fertilizer. You also are typically use a much higher water volume for fertilizer than you would when applying a fungicide or herbicide. We would suggest at the very least applying the fertilizer separately, and perform a tank mix test with the Q4 Plus and Propiconazole before applying it to the yard to test for compatibility in the tank.
