Another spray can be made from plants with pungent aromas, such as garlic, marigolds and chives. One recipe' is to put the cloves, petals, leaves or whatever into a pot, add enough water to cover, bring the mixture to boiling point, remove from the stove and strain off the solid matter. Dilute the remaining liquid with four or five parts of water, stir for five to ten minutes, and spray. Another method is to liquify the raw material, adding water to cover, in a blender. Strain off solid particles, mix the remaining liquid in the proportion of two or three teaspoons to a quart of water, and spray.

Other simple formulas include the following:

  • Tomato stems and leaves boiled in water destroy aphids, etc.
  • Lime mixed with wood ashes prevents maggot damage.;
  • Hot pepper mixed with equal amounts of water and soap powder is effective against tomato worms.
