This is a manifestation of a fungal invasion, small microorganisms that are many times pathogens and can cause various disorders, not only in plants, but also in humans and pets, although obviously, each fungus is susceptible to invade one or more specific species.
Fungi can be a real threat to the health of the plant, However, they can also be prevented and effectively eradicated when the infestation has already occurred, in addition, it is possible to do so using natural elements that are not polluting to the environment. Do you want to know how? Then do not stop reading this article because in it we explain how to make a homemade fungicide.
Homemade fungicide with milk and bicarbonate
The types of fungus that can affect a plant They are different, however, practically all of them belong to the family Erysiphales, and can be seen with the naked eye as if they were a kind of white or grayish powder (the tone depends on the species of fungus). Before we can observe this fungus with the naked eye, dust already begins to form under the leaves and in the ground, therefore, periodic inspections are necessary to detect this condition as soon as possible.
A fungicide is a substance capable of destroying pathogenic fungi and there are many completely natural elements that have this property and that can be used to treat fungi in plants.
The homemade fungicide with milk and bicarbonate Not only is it useful to eradicate fungal infestation, but it is also suitable to provide nutrients to plants, to prepare it you will need the following ingredients:
- 8 parts of rainwater (it can be tap water, but in this case it must be allowed to stand for 2 days)
- 2 parts skim milk
- 20 grams of baking soda for each liter of mixture
Mix the water with the milk and then add the corresponding amount of bicarbonate, put it in a sprayer, shake and apply on the plant daily at sunset.
Once the fungi are eradicated, you can apply it preventively every 15 days.

Homemade fungicide with soap and baking soda
Another way to make a homemade fungicide is using, again, the bicarbonate. It is one of the most common and also medicinal substances, since it is antiseptic, regulates pH and also favors healing processes, so it is not surprising that it is a basic ingredient in multiple homemade fungicides.
To prepare it you will simply need to mix the following ingredients:
- 4 tablespoons of baking soda
- 4 tablespoons of neutral soap
- 3.5 liters of water
- 1 teaspoon of vegetable oil
When this mixture acquires a homogeneous appearance, add it to a sprayer and apply on the plants at sunset, since applying a fungicide under sun exposure can cause irreversible burns on the plant.
You can apply it daily until the infestation is eradicated and then every 2 weeks as a preventive measure.
Before applying massively any type of homemade fungicide on a plant, it is advisable to carry out a test on a small part of the plant, since some plants can react badly to some of the components, and in this case, a massive application could be disastrous.
