Biologicals for plant protection can inhibit pathogens in the soil, seeds and roots of plants. They also prevent the development of leaf and fruit diseases after application of the solution to the surface. Consider the composition and scope of "Trichodermina", the principle of action and instructions for use. With what drugs it can be combined, what is allowed to replace it and how it should be stored.
Description and scope of use
"Trichodermin" is a completely biological preparation, consisting of certain species of fungi. The principle of action is based on the fact that fungi develop on the mycelium of pathogenic fungi and plant residues, which contain a lot of cellulose. The mycelium of Trichoderma at the beginning of its development is white, then turns green. The fungus develops best at a temperature of 24-25 ° C, the minimum for it is 8 ° C, the maximum is -32 ° C.
After treating seeds with "Trichodermin" or introducing it into the ground, fungi begin to develop on the roots of plants, because of this, their absorption capacity increases, they create a biobarrier for pathogens, compete with them for nutrition and suppress their development with substances that they produce.
The effectiveness of "Trichodermina" does not depend on the type of soil, acidity and humus level. Fungi are able to develop not only on treated seeds, but also after being applied to the soil surface in the form of granules, after being applied during plowing and loosening. You can add the drug to the soil mixture for greenhouses, to the soil during planting.
The abundance of viable trichoderm fungi persists throughout the season. Due to the suppression of pathogens, the growth of the root system and the aboveground part of the crops is accelerated, the resistance to infections is increased, and the yield increases.
Composition and form of release
"Trichodermin" is a fungicidal biological product based on fungi of the Trichoderma harzianum species (strain 18 VIZR and VKM F-4099D). The products are produced in different preparative form, which depends on the strain, the nutrient medium used, the titer of the drug and the cultivation method.
Instructions for use
For the treatment of potato bushes during the growing season, dilute 20 g of the product in 5 l of water (50-100 ml of concentrate per 10 l), this volume is spent on a hundred square meters. Vegetables, roots, herbs, flowers and ornamental crops are sprayed with a solution of 20 g of fungicide per 5 liters (per 1 hundred square meters). To soak 10 kg of seeds, prepare a solution of 20 g per 1.5 l of water, to soak seedling roots - 20 g per 5 l (per 100 seedlings).
For legumes, sunflowers and corn, the solution is prepared in a different concentration: 20 g per 10 l (or 100 ml per 10 l) and spend it on 2 ares. For spraying 1 weave of fruit, grapes and berry bushes, a liquid is prepared from 20 g per 5 liters (or 50-100 ml per 10 liters). For processing 100 seedlings - 20 g per 3 liters of water.
"Trichodermin" can be used for soil cultivation in spring (to suppress pathogenic microflora and develop beneficial microflora) and in autumn (to improve the soil, accelerate the formation of humus and decomposition of plant residues). Application rate: 20 g per 10 l (100 ml per 10 l), consumption per hundred square meters.
How to properly prepare the solution: dissolve the powder in 2 liters. be sure to warm, settled water, stir and leave in a dark place for 1-2 hours to activate the fungus. Then add water to the required volume.
If Trichodermina concentrate is used, then the entire volume is mixed immediately with water before spraying. Saplings and seeds are cultivated in partial shade or shade so that the sun's rays do not fall on them.
Processing should be carried out at an air temperature of more than 8 ° C, on a cloudy day. Use the solution completely within 6 hours after preparation.
"Trichodermin" is completely safe for humans, does not contain any toxic substances. Does not harm plants, animals, insects and soil, does not accumulate in it. Does not impair the taste of fruits and vegetables.

To work with the fungicide, it is enough to wear gloves and a respirator. Poisoning by the drug is extremely rare. After finishing work, you should wash your hands and face, rinse the solution from the skin if it gets on body parts.
Biofungicide can be mixed with other drugs of a similar effect, with the exception of Mikosan. If you mix it and use it together with Fitosporin, Fitodoctor, Adjumax, Gaupsin and Liposam, the overall effectiveness of the funds will increase.
Do not mix "Trichodermin" with mineral fertilizers, disinfectants and synthetic fungicides.
Storage terms and rules
Trichodermin is stored undiluted for 2 years. Be sure to keep it in its original packaging, closed and undamaged. Observe storage conditions: at above-zero temperature (do not freeze), in a dry and dark place. Do not store near chemical pesticides or fertilizers.
After the expiration of the storage time, the drug "Trichodermin" is not recommended to be used, it loses its properties. Store the solution for no more than 6 hours.
Analogues of "Trichodermin"
The fungicide can be replaced with biologics based on Trichoderma harzianum. For agriculture: "Trichocin", "Glyocladin" in various formulations and "Sternifag". In private households, you can use "Trichocin" and "Glyocladin".
"Trichodermin" is a biofungicide known to many gardeners. It is easy to use, it is used to prevent the appearance of fungal infections in plants of the garden and vegetable garden, for their treatment, if they are in an unregulated form. Differs in a low consumption rate, while high efficiency. Works at positive temperatures, the action does not depend on the type of soil and crop variety. Completely safe for treated plants and the environment.
