The main tomato fungi

Tomato ( Solanum lycopersicum ) is a solanaceous plant from America. It is one of the horticultural fruits (fruit in botany, vegetable in food) most appreciated by farmers and consumers, due to its taste and nutritional qualities. It is very strange to see a garden that does not have at least one variety of cultivated tomato. In addition, tomato plants are voracious plants that adapt very well to all types of soils, although it is advisable to grow them in soils rich in nutrients and well fertilized.

Most of the varieties are climbers, which is why they tend to be covered, and very few grow at ground level. They are plants that must be pruned as they grow, removing the oldest leaves from the lower part of the tomato. This will facilitate aeration and access to sunlight, preventing it from some fungal problems, since caring for the plant is the first antifungal method .

The two main diseases that affect the tomato plant are mildew and powdery mildew . Depending on the humidity, the temperature, the sensitivity of the variety or the initial inoculum, the tomato will be affected by one or another disease. Combating these diseases is possible in organic farming using fungicides with copper or sulfur, but next we will see how to make homemade fungicides for tomatoes .

Homemade baking soda fungicide for tomatoes

Sodium or sodium bicarbonate is a white, soluble compound often used to combat fungal pests on many plants, one of which is the tomato plant.

We can make homemade fungicide with baking soda for tomatoes easily by mixing 4 teaspoons of baking soda, 1 of horticultural oil and citric or molasses oil in approximately 4 L of water. This should be mixed well until the baking soda dissolves. Finally, this mixture will be placed in a spray bottle and the part of the plant with symptoms of fungal disease will be sprayed. If bicarbonate is not available, potassium carbonate can be used.

Homemade tomato fungicide made with cornstarch

Corn flour or cornstarch is another very common ingredient in cooking that has antifungal properties.

To make this homemade fungicide for tomatoes , mix 1 cup of cornmeal with 5 cups of water and let it rest for an hour or until it takes on a dull and milky appearance. Subsequently, the solid flour must be removed and the resulting milky liquid sprayed on the tomato plants.

Homemade tomato fungicide made with vinegar

Vinegar is also a common element in kitchens with antifungal properties . To make vinegar-based fungicide for tomatoes, we must dilute 3 or 4 tablespoons of vinegar approximately in 4 L of water and spray this mixture on the tomato plants. Do it daily, when the sun is not fully on the plant, until you see the fungi disappear.

The most natural is usually apple cider vinegar , although white vinegar is the one that is most effective in treating plant fungi, you can use either of the two.

Essential oils, excellent fungicides for tomatoes

There are several types of essential oils with antifungal properties that are effective when applied to plants such as tomatoes, both to prevent and treat fungal problems. Among these oils are:

  • Citric oil.
  • Oil of oregano.
  • Grape root oil
  • Orange oil.
  • Garlic oil.
  • Peppermint oil.
  • Tea tree oil.

To make fungicides based on these oils, they can be mixed with other homemade fungicides , or diluted in water. Apply them once a day until you notice that there are no more fungi, but remember not to do it in the hours of strong sun.

Compost tea as a fungicide for tomatoes

Compost tea is a preparation made from compost diluted in water and is so named because of its similarity to the color of liquid iced tea.

To make compost tea , you must fill a bucket with compost and water equal parts. This mixture should be left to rest between 10 days and 14 days, later, remove the solid elements and dilute it again in water until the mixture presents the adequate consistency to be sprayed. Finally, we will apply the mixture to the leaves of the tomato plant, especially those that we see that show symptoms of fungal infection. Again, it can be applied daily, outside the hours of sunlight, as many days in a row as necessary until the fungi have completely disappeared from the tomato plant.
