Notes:

  • RATES PER ACRE are for semi-dwarf apple trees with dilute tree row volumes of app. 175 to 200 GPA. Increase or decrease rate per acre (within label specified rate) depending on tree size.
  • MATING DISRUPTION (MD) for adult moths (codling moth, oriental fruit moth, leafrollers) should be deployed whenever possible. But MD typically needs to be supplemented with insecticides.
  • INSECTICIDE and FUNGICIDE substitutions are several. Be sure to read the label for specific pest instructions. The label and federal and state regulations are law and supercede all recommendation(s) herein.
