Tools Needed

To apply Propiconazole 14.3 Fungicide, a hose-end sprayer, handheld pump sprayer, backpack sprayer, or skid sprayer is needed. For spot treatments, we recommend a handheld pump sprayer or the backpack sprayer. For large areas, we recommend using the hose-end sprayer.

  • Step 1: How much Propiconazole 14.3 is needed depends upon the disease you are trying to treat. The application rate can vary from 0.5 to 4 fluid ounces per 1,000 sq. ft. Find the square footage of your treatment area by multiplying the area’s length and width in feet (length x width = sq. ft.). This will tell you how much product you need based on the targeted disease. For example if you are treating for dollar spot and have 2,000 sq. ft. of lawn, you will need to apply 2 to 4 fl. oz. of Propiconazole 14.3 to cover that area. You will apply with water in a sprayer, making sure you have enough water to get thorough coverage. For small jobs, we recommend a gallon sprayer as 1 gallon of water will typically treat 1,000 square feet.
  • Step 2: Fill the sprayer’s tank halfway with water and then add the labelled amount of Propiconazole 14.3 Fungicide for your targeted disease. Add the rest of the water to your spray tank and shake to mix well. Apply Propiconazole 14.3 Fungicide to label listed plants and other types of vegetation. Propiconazole 14.3 Fungicide can be mixed with other products to enhance the performance, but read the label for those instructions before use.
  • Step 3: Apply the mixture to the plants and turfgrass you wish to protect, preferably on a fan spray nozzle setting for uniform coverage. Spray to the point of wet, not runoff. Make applications as needed, but do not apply more than 16 ounces per 1,000 square feet, or more than 5.4 gallons per acre of product per year.
