School Garden: Trichoderma - what kind of mushroom, how and when it is used

Despite the frightening name, trichoderma is not a disease, but rather a cure for many garden problems. And by taming this substance, you can get a faithful ally in the fight against the most common fungal diseases.

For a start, let's see what kind of beast is such a trichoderma. It is just an antagonist mushroom of the Ascomycota division of the Hypocreaceae family. Its main value for gardeners is the fact that in the process of development Trichoderma produces several types of antibiotics that destroy phytopathogenic fungi. We will deal with this in more detail.

How trichoderma works

Trichoderma colony

In fact, trichoderma is a common soil fungus that has been used in agriculture for more than 70 years. Developing on the surface of the roots of any plants, it increases their absorption capacity, creates a natural barrier to pathogenic flora and strengthens the immune system. In addition, in the process of feeding, trichoderma decomposes polysaccharides, converting the nutrients present in the soil into an easily digestible form.

Its main advantage is that the ridges treated with Trichoderma are almost never affected by fungal diseases. That is, late blight, white, gray and root rot, fusarium, tracheomycosis, fomoz, alternarioz, askohitoz, gelmintosporioz, black leg, verticillary wilt, powdery and downy mildew bypass the ridges side.

Trichoderma under a microscope

On the basis of the spores, mycelium and wastes of Trichoderma produce such drugs as Trichodermin, Trichoplant, Glyocladin, Trichocin, etc.

The yield of plants is also changing - thanks to enhanced nutrition, they give almost a third more fruit than usual.

Trichoderma and preparations based on it are non-toxic to people, animals, insects and fish, do not accumulate in the soil and do not affect the taste and appearance of the grown products.

How to apply trichoderma

The timing and method of using trichoderma depends on the problem you want to solve. In principle, its introduction at any stage of growing plants will only benefit them. But it must be remembered that trichoderma is able to develop only at a temperature of 5 to 35 ° C, which means that it is useless to use it in the cold season (in early spring or late autumn after harvest).

Seed treatment with trichoderma

Presowing seed treatment with trichoderma is carried out 1-3 days before sowing. They are soaked in a solution prepared according to the instructions from the packaging of the drug. Most often, 50 ml of the drug per 100 ml of water and soaking for 60 minutes is sufficient.

The seeds treated in this way germinate better and are less likely to suffer from fungal diseases in the seedling stage.

Treating seedlings with trichoderma

To strengthen the immunity of plants and maximize survival, treatment with trichoderma can be carried out right before planting seedlings in a permanent place. To do this, prepare a nutrient solution at the rate of 100 ml of the drug in 10 liters of water and spill them with seedlings. If the seedlings have already been taken out of the pots, you can immerse them in a solution of trichoderma for 30 minutes and then plant them.

Soil trichoderma treatment

Treating the soil with trichoderma makes sense in two cases - as a preventive measure before planting plants and during spring or autumn tillage. In the first case, for this purpose, a solution is prepared at the rate of 50 ml per 10 liters of water and watered with the resulting mixture of 10 square meters of soil. In the second case, 150 ml of the drug are already taken on a bucket of water and they are shed with the resulting volume of 1 hundred parts of earth.

In the spring, the treatment is carried out a week before planting and sowing seeds, in the fall - immediately after harvesting or when plant residues are embedded in the ground.

Treatment of plants with trichoderma in diseases

If all the terms of preventive treatments have already been missed, and you have found the first signs of late blight, white or gray rot and other diseases on plants, you can urgently treat them with the help of trichoderma. To do this, 75-100 ml of the drug are added to a bucket of water and plantings are shed under the root every 10-12 days until the signs of the disease disappear. It is even better to do this before harvesting - the drug is absolutely safe, so it will not affect the quality of the products.
