You could use a mixing rate of 1-2 fl oz. of Propiconazole 14.3 per 1000 square feet but we would recommend checking the label for a more specific rate for the disease you're treating for. This would be mixed in however much water it takes to cover that 1000 sq. ft. Generally 1-2 gallons will cover the area but this depends on the specific equipment being used, how fast you are walking, and the pressure of the sprayer.
The active ingredient Propiconazole is a systemic fungicide meaning when sprayed on the top and leaf surfaces of the plant, it translocates to the tissues of the plant transferring its toxicity to the targeted fungus. Contact fungicides are not taken up into the plant tissue and only protects the pant where the spray is deposited. Per the product label, you can mix it with a contact fungicide such as Azoxy 2SC as long as it's labeled for the disease you're treating for.
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.
You can apply fertilizer and fungicide such as Propiconazole 14.3 Fungicide at or near the same time as long as you are not treating a disease which you know could be worsened with fertilizer applications, such as brown patch. If you have temperatures over 90 degrees during the day, then you want to make your applications in the morning or evening when temperatures are cooler.
You should always rotate fungicides after every 2-3 applications of one from one group to prevent resistance issues. Propiconazole 14.3 Fungicide is a Group 3 Fungicide. So you should rotate to one that contains a group 1 such as Clearys 3336F or a combo of group 3 and 11 such as Pillar G or Headway G depending on the target disease and area treating. It's possible that you just may not have had the right conditions for diseases to thrive in your area all this time but repeated applications of the same product does cause resistance.
Over applying a product such as Propiconazole 14.3 may cause injury to your lawn and/or may cause the product to not work effectively. We would suggest contacting the manufacturer (Quali-Pro) directly at 800-242-5562 for more information.
Yes, if you are using a product like Propiconazole 14.3 Fungicide that is designed for larger applications, then you would need to divide down the rates for smaller volumes of water.
