Hi Farmers! Now that the heat is coming, it is one of the delicate moments that the plants in our garden can go through. It is a very favorable time for the development of fungi, and especially if there are storms, since there will also be humidity, so we are going to need these ecological fungicides to prevent and cure fungi.

Collar and root rot caused by fungi

Today we will talk about several types of totally natural ecological fungicides, which you can do yourself because they are very simple, and that will help you prevent the most common fungal diseases in the garden.

1. Baking soda

It is an effective fungicide both to prevent the appearance of fungi, and to eliminate them if they have already appeared, as long as they are not in a very advanced state. It is effective against mildew, powdery mildew, anthracnose and blight.

Preparation: Dissolve 2 tablespoons of baking soda in 1 liter of water. To this you can add a small spoonful of natural or neutral soap.

Use: spray the preparation, twice a day for a week, on the affected areas or on all the leaves. Continued use is required to ensure its effectiveness.

2. Coffee

Previously, the properties of coffee in the garden have been discussed, and one of them is that it can prevent fungi in general.

Preparation: let the coffee grounds dry, this can be done, leaving them to dry in the sun for a week.

Use: spread the grounds around the plant, so that they absorb moisture, it is recommended to spread them on top of mulching or plastic, so that they do not acidify the soil in the long term.

3. Bordeaux broth

Although some processed products are used for its preparation, it is considered an ecological fungicide, since it is environmentally friendly and its mineral component (copper sulfate) is used in the same way that it is extracted from the natural environment.

Preparation: at 1% concentration of the active ingredient, 10 grams of copper sulphate is mixed in half a liter of water, on the other hand, in a different container, 10 grams of quicklime is mixed with another half liter of water. Each mixture must be stirred very well until it has been dissolved correctly and left to stand for 3 hours. Then they must be mixed, but it is very important to pour the solution of copper sulfate into the solution of lime, and not the other way around, since toxic gases could be produced, this mixture will be made slowly. Once we have the final solution, we must measure its pH, which must be between 6-7, if it is not between these values ​​and it is less than 6, we will have to add a little more lime.

IMPORTANT: Ecological fungicides prepared with quicklime or copper sulfate are quite irritating to the skin and eyes, so they must be handled with extreme care.

Use: The final solution is sprayed on the plant sparingly, throughout the plant.

4. Antifungal preparation made with milk

Surprisingly, this is a very effective fungicide against the most common fungi, such as mildew, botrytis, rust, etc., due to the salts and lactic acid it contains.

Preparation: To obtain 1 liter of this fungicide, you have to mix 700 ml of water with 300 ml of milk, you can add 10 grams of sodium bicarbonate, this is optional.

Use: Spray all over the plant, both on the upper part and the lower part.

5. Infusion of garlic and onion

Both garlic and onion have insecticidal and fungicidal properties. They can be used together or separately. It is used as a preventive measure against common fungi and is also a good insecticide.

Preparation: For 750 ml of water add a quarter of an onion and two heads of garlic. Let macerate overnight or 24 hours. Then bring it to the boil, strain it so that only the liquid part remains and let it cool.

Use: spray all the leaves, once a day and every 10 days, especially when the plant is young.

6. Horsetail (Equisetum arvense)

One of the many benefits that horsetail offers us is its great effectiveness against fungi. It is one of the most effective remedies, especially it is very useful against rust.

Preparation: it is made in infusion. To do this, the plant should be soaked overnight (it is recommended to use a medium-sized plant per liter or liter and a half of water). The next day it is infused, that is, it is boiled for 2-3 minutes, the remains are strained and it is allowed to cool before using it.

Use: with the resulting infusion it is sprayed on the leaves, once a day. Its repeated use will be more effective.

One of the great advantages of using all these types of fungicides is that they are all very cheap and easy to make. All should be used at times of the day when there is no sun, because being natural they degrade quickly. In addition, homemade fungicides should be used soon, before 3-4 days have passed after their preparation so that they do not lose their properties.
