This insecticide’s mode of action is through suffocation of eggs, larvae and nymphs of insects and mites and adults of soft-bodied insects. This mode of action necessitates total spray coverage. As a fungicide this oil interferes with the attachment of the pathogen to the host and acts as a suffocant.

This oil may be used to control mite and insect pests in the egg stage, including: spider mites, eriophyid mites, armored scale, soft scale, mealybugs, psyllids, whiteflies, aphids, leafrollers, leaftiers, webworms, cankerworms, plant bugs, leafhoppers and adelgids. This oil will kill other immature forms if spray covers the insect.

See APPLICATION RATES tables for species claimed to be controlled on specific types of plants. Use this oil only on the types of plants identified in the APPLICATION RATES tables.

How To Use The Ready-To-Spray System:


  1. Shake well before using.
  2. Connect sprayer to hose.
  3. Turn on water.


  1. Before spraying, point nozzle in the direction you want to spray.
  2. Bend small plastic tab back and turn knob clockwise to ON position.
  3. Begin spraying.


  1. To stop spraying, turn knob counter clockwise to OFF position.
  2. Turn off water.
  3. Relieve water pressure by bending plastic tab back and turning knob to ON position until water slows to a drip. Then turn knob back to OFF position.
  4. Disconnect sprayer from hose.
