Fungi are not capable of killing your plants; however, they do lend an unsightly appearance to them and cause the leaves to turn brown and eventually fall off. If you are one of those gardeners or landscapers who are looking out for the use of non-hazardous products to eliminate fungal agents, then the idea of mixing together some ingredients that are easily available at home with vinegar to make a natural fungus fighter may probably appeal to you.

Basic Apple Cider Vinegar Fungicide


    • Mix ingredients: To make this fungicide, specifically use cider vinegar with an acidity of 5%. Mix about a gallon of water with three tablespoons of cider vinegar. In addition to mildews, scabs, and leafspots, this vinegar fungus fighter is effective against black spot diseases that commonly affect rose plants and aspen trees.
    • Spray: Spray this fungicide on the affected plants during the morning hours for best effects.

Enhanced Apple Cider Vinegar Fungicide


    • Pour water into the plant sprayer: Clean the plant sprayer well and pour into it two gallons of water.
    • Mix all ingredients: Using the water as a base, add into the sprayer six tablespoons of organic apple cider vinegar, two tablespoons of dark molasses, one tablespoon of baking soda, and two tablespoons of vegetable or citrus oil. Mix the ingredients well by shaking the sprayer.
    • Spray: The fungus fighter is to be used only on the affected parts of plants. It is not advisable to use it for prevention purposes.Lightly spray the fungus fighter over the leaf tops and bottoms of the affected plants. The best time to use this spray is early mornings or evenings—when the temperature is relatively low and the surroundings are cool.
    • Repeat spraying: Wait for a week before you spray the affected plants again with the fungus fighter.

Things to Consider

  • Capacity of the sprayer: Note that the abovementioned recipe for the enhanced fungal fighter requires a 2-gallon sprayer. If you are using a one-gallon sprayer instead, use half the quantity of the ingredients specified above.
  • Protect your skin and face: Some people find certain ingredients used in the preparation of the fungus fighter to be highly irritating to their eyes, mucous membranes, and skin. So, it is important that you use protection for your face and skin when using the spray.
  • Treating mildew affecting indoor plants: The natural vinegar fungus fighter can be used in small amounts in a sprayer to treat fungal conditions, such as mildew, affecting indoor plants.
  • Test the plant fungus fighter before applying it: Certain plants develop side-effects when treated with fungal fighters. Therefore, before applying the spray, test it out on a small plant area. You can apply a very small portion of the fighter on a lower leaf and wait for at least 24 hours to check for side-effects.
