Horticultural Oil

Use to suffocate insects, especially on fruit trees, which can't be treated with insecticides.

You can make the oil from diluted vegetable oil (using a small quantity of detergent to allow the oil and water to mix).

  • 1 cup vegetable oil
  • 1 tablespoon dish washing liquid

Mix 1 tablespoon with 2 cups of water. Fill a spray bottle and shake well.
