When using Heritage SC Fungicide at a rate of 0.4 oz per 1,000 square feet, it can treat up to 10,000 square feet. At the rate of 0.8 oz per 1,000 square feet, Heritage SC can treat up to 5,000 square feet. Water is just the carrier so the area it will treat with your 25 gallon tank, depends on the size area you can treat with that much water. We recommend to calibrate your sprayer to help determine the mix rate that will fit your needs.
