How to Use

• Step 1: Determine how much Daconil Action Fungicide you need by measuring the square footage of the treatment area. To do this, measure the treatment area's length and width in feet, then multiply them together (length x width = square footage). Use Daconil Action at a rate of 1.0 to 5.4 ounces per 1,000 square feet (rates vary depending on target disease). For a post-disease treatment mix Daconil Action at a rate of 2.0 to 5.4 fl. ounces per 1,000 square feet (rates vary depending on target disease). 
• Step 2: In a sprayer of your choice, fill the sprayer halfway with water and add the appropriate measured amount of Daconil Action Fungicide. Fill the sprayer the rest of the way with water and shake well, and then you will be ready to spray.
• Step 3: Spray the fungicide onto the plant's leaf, setting the sprayer to a fan spray setting for even coverage.
• Step 4: Depending on severity, follow-up applications should be from 7 to 10 days, 7 to 21 days, or 14 days. Do not apply more than 12.5 fluid ounces per 1,000 square feet per growing season.
