Gulf Atlantic Zone

Large Patch Application timing for large patch begins in the fall when average soil temperatures at 2” depth fall to an average of 70-72ºF for five consecutive days when taken at 11:00 am. Additional large patch applications may be needed in the fall and winter depending on your species, location, temperature, and rainfall. Rotate applications to Densicor ® if the annual maximum of Mirage ® Stressgard ® has been reached (6.5 fl. oz. per 1,000 ft 2 per year). Large patch is a stem and crown disease so applications should not be watered in, but instead be applied in a carrier volume 1.0-2.0 gallons per 1000 square feet. The Envu program below has a satisfaction guarantee and if your expectations are not met, please contact your Envu Distributor or Envu Area Sales Manager.
