How to Use

• Step 1: Determine how much Spectro 90 WDG Fungicide to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment area's length and width in feet, then multiply them together (length X width = square footage). For acreage, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acres). To cure diseases in turf, apply 3.0 or 3.72 oz. of Spectro 90 WDG Fungicide per 2 to 4 gallons of water per 1,000 sq. ft. To prevent diseases in turf, use 2 to 3.72 oz. of product per 2 to 4 gallons of water per 1000 sq. ft. Refer to the product label for specific application rates and restrictions. 
• Step 2: Fill the sprayer tank with half the amount of water, add the proper amount of product, and pour in the remaining half of the water. Close the tank lid and shake until well-mixed. 
• Step 3: Spray the top and bottom of the foliage leaves until wet, but not to the point of runoff. After 8 to 12 hours after application, irrigate the treated area with 0.1 to 0.25 inches of water. A second application can be made when 14 days have passed after application.
