Organic Remedies for Insects, Mildew, & Fungus
Natural Insecticide
For control of aphids, leaf rollers, cabbageworm, whitefly, etc. (also negatively affects beneficial insects).
Recipe
Allow 3 ounces of finely chopped garlic to soak in 2 teaspoons of mineral oil for 24 hours. Add 1 pint of water and 1/4 ounce of liquid dish soap. Stir well and strain into a glass jar for storage. This is your concentrate.
To Use
Combine 1-2 tablespoons of concentrate in one pint of water to make the spray. Be careful not to make the solution too strong! While garlic is safe for humans, when combined with soap and oil the mixture can cause leaf injury on sensitive plants. Always test the lower leaves of plants to make sure they are not affected. Apply about once a week until bugs are gone.
