Application Guidelines

Ground application: 
  • Best results will be obtained when application is made when the target pest is active.
  • Apply as a broadcast application in sufficient water to ensure thorough coverage of the foliage.
  • Ensure uniform application.
Aerial application:
  • Apply only by fixed-wing or rotary aircraft equipment which has been functionally and operationally calibrated for the atmospheric conditions of the area and the application rates and conditions of the label.
  • Ensure uniform application. To avoid streaked, uneven or overlapped application, use appropriate marking or guidance devices.
  • Coarse sprays are less likely to drift, so avoid combinations of pressure and nozzle type that will result in fine particles (mist).
  • Do not allow the pilot to mix chemicals to be loaded onto the aircraft. Loading of premixed chemicals with a closed system is permitted.
