Notes: A water carrier volume of 1.5 to 2.0 gallons per 1,000 ft² is recommended. Use a flat fan air-induction nozzle that provides thorough plant coverage. Do not water-in fungicide applications unless noted. 1 Apply Primo Maxx or Trimmit® 2SC Plant Growth Regulator at label rates. Application rates of PGR’s will vary with golf course. For those golf courses trying to suppress Poa annua , use Trimmit 2SC PGR at recommended rates. 2 Daconil Action and Daconil WeatherStik® fungicides are interchangeable.
