Propiconazole 14.3 Fungicide, manufactured by Quali-Pro, treats war and cool-season grasses, trees, bushes, and flowers for various plant diseases.
This concentrated product can be used as a preventative method to prevent diseases from forming or as part of a treatment plan to bring lawns and plants back to life.
Propiconazole 14.3 is easily applied with a hose-end sprayer to cover large areas or a pump sprayer for spot treatments. It will treat and control brown patches, dollar spots, rust, and powdery mildew.
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 or backpack sprayer. For large areas, we recommend using the hose-end sprayer.
How to Use
- 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 and size of the treatment area. For example, if you are treating for dollarspot 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 use it with water in a sprayer, ensuring you have enough water to get thorough coverage. We recommend a gallon sprayer for small jobs, as 1 gallon of water will typically treat 1,000 square feet.
- Step 2: Fill the sprayer's tank halfway with water and add the labeled Propiconazole 14.3 Fungicide for your targeted disease. Add the rest of the water to your spray tank and shake to mix well. Apply to label listed plants and other types of vegetation. It can be combined with different products to enhance 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.
Where to Use
Propiconazole 14.3 Fungicide can be used on landscapes with cool—and warm-season grasses and ornamental plants and injected into trees.
Do not apply in areas where livestock animals are grazing. It is ideal for use on residential or commercial turfs and lawns, golf courses, sports fields, and recreational lawns. It is ideal for lawns in areas that hold moisture to prevent fungus diseases from forming.
When to Use
When using Propiconazole 14.3 Fungicide, the vegetation type will determine when and how often it should be applied for total control of listed diseases.
It can be used as a preventative product to prevent fungus diseases from forming in vegetation.
It can also be used as a control method to kill various diseases after they appear. For disease control on landscapes, 6 to 8 ounces of mixed product should be applied every 21 days.
Safety Information
Propiconazole 14.3 Fungicide is safe to use around pets and children when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product.
Keep all people and pets off the treated areas until dry.
Special Considerations
Propiconazole 14.3 Fungicide cannot be stored or mixed with oxidizing agents and cannot be applied through any form of irrigation system.
