How to Use

• Step 1: Determine how much Dithane 75DF Rainshield Specialty Fungicide to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area 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 treat sod farm turf, limit to a maximum of 4 applications per year and a maximum rate of 23.2 lb of Dithane 75DF Rainshield Specialty Fungicide in 100 gallons of water per acre per application. For cool-seasoned grasses; greens, tees and aprons on golf course, limit to a maximum of 5 applications per year at a maximum application rate of 23.2 lb of product in 100 gallons of water per acre per application. For cool season grasses; fairways on golf courses, limit to a maximum of 4 applications per year at a maximum application rate of 23.2 lb of product in 100 gallons of water per acre per application. For warm season grasses; greens, tees and aprons on golf courses, limit to a maximum of 4 applications per year at a maximum application rate of 23.2 lb of product in 100 gallons of water per acre per application. For warm season grasses; fairways on golf courses, limit to a maximum of 3 applications per year at a maximum application rate of 23.2 lb of product in 100 gallons of water per acre per application. All other assorted grass turf, use 4 to 8 oz. of product in 1 gallon of water per 1,000 sq. ft. depending on the disease. For outdoor (field nursery) or greenhouse use, apply 1 to 2 lbs. of product in 100 gallons of water per acre.
• Step 2: When using a handheld pump sprayer, premix Dithane 75DF Rainshield Specialty Fungicide as a slurry in a small container before adding to the spray tank. Pour half of the required amount of water into the handheld sprayer and the other half into the separate tank mix container. Slowly pour the appropriate amount of product into a small container containing part of the required amount of water while mixing. Mix until the product is thoroughly wetted. Add additional water if necessary to make solution flowable. Add the contents of the slurry tank into the handheld pump sprayer filled with half the amount of water, continue filling tank with remainder of water and mix well. Always add this product into solution prior to adding any additional materials to the tank.
• Step 3: When using large volume spray equipment such as chemigation or aerial, spray the Dithane 75DF Rainshield Specialty Fungicide solution 5 to 10 feet above the crop canopy. Applications with handheld pump sprayers should be used to spray plant foliage until it is thoroughly wet, but not to the point of runoff. Repeat at 10-day intervals as long as condition persists.
