Fungi are not capable of killing your plants; however, they do give them an unsightly appearance and cause the leaves to turn brown and eventually fall off. If you are one of those gardeners or landscapers who is 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 will probably appeal to you.

Basic Apple Cider Vinegar Fungicide

To make this fungicide, use apple cider vinegar with an acidity of 5 percent. Mix about a gallon of water with 3 tablespoons of cider vinegar. In addition to mildews, scabs, and leafspots, this fungus fighter is effective against black spot diseases that commonly affect rose plants and aspen trees.

Spray this fungicide on the affected plants during the morning hours for the best results.

Enhanced Apple Cider Vinegar Fungicide

Clean a plant sprayer well and pour into it two gallons of water. Using the water as a base, add into the sprayer 6 tablespoons of organic apple cider vinegar, 2 tablespoons of dark molasses, 1 tablespoon of baking soda, and 2 tablespoons of vegetable or citrus oil. Mix the ingredients well by shaking the sprayer.

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.

Wait for a week before you spray the affected plants again with the fungus fighter.

Things to Consider

The recipes for the enhanced fungal fighters require a 2 gallon sprayer. If you are using a 1 gallon sprayer instead, use half the quantity of the ingredients specified above.

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.

The natural vinegar fungus fighter can be used in small amounts in a sprayer to treat fungal conditions, such as mildew, affecting indoor plants. 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.
