Biological products for plant protection can suppress pathogens found in the soil, on seeds and roots of plants. They also prevent the development of diseases of leaves and fruits after applying the solution to the surface. Let's consider the composition and scope of application of Trichodermin, the principle of action and instructions for use. What drugs can it be combined with, what can it be replaced with, and how should it be stored.
Description and scope of use
"Trichodermin" is a completely biological preparation consisting of a certain type of mushroom. The principle of operation is based on the fact that mushrooms develop on the mycelium of pathogenic fungi and plant residues, which contain a lot of cellulose. Trichoderma mycelium is white at the beginning of its development, then turns green. The fungus develops best at a temperature of 24-25 °C, its minimum is 8 °C, and its maximum is -32 °C.
After treating the 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 the substances they produce.
The effectiveness of Trichodermin does not depend on soil type, acidity or humus level. Fungi can develop not only on treated seeds, but also after application to the soil surface in the form of granules, after application during plowing and loosening. You can add the drug to soil mixtures for greenhouses and to the soil when planting.
The number of viable Trichoderma fungi remains maintained throughout the season. Due to the suppression of pathogens, the growth of the root system and above-ground parts of crops accelerates, resistance to infections increases, and productivity increases.
Composition and release form
“Trichodermin” is a biological product with fungicidal action, which is based on fungi of the species Trichoderma harzianum (strain 18 VIZR and VKM F-4099D). The products are produced in different preparative forms, which depend on the strain, the nutrient medium used, the titer of the drug and the cultivation method.
Instructions for use
To treat potato bushes during the growing season, dilute 20 g of the product per 5 liters of water (50-100 ml of concentrate per 10 liters), this volume is consumed per hundred square meters. Vegetables, root vegetables, 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, for soaking the roots of seedlings - 20 g per 5 l (per 100 seedlings).
For legumes, sunflower and corn, the solution is prepared in a different concentration: 20 g per 10 l (or 100 ml per 10 l) and consumed per 2 acres. To spray 1 hundred square meters of fruit, grape and berry bushes, prepare a liquid of 20 g per 5 l (or 50-100 ml per 10 l). To treat 100 seedlings - 20 g per 3 liters of water.
"Trichodermin" can be used for soil cultivation in the spring (to suppress pathogenic microflora and develop beneficial ones) and in the fall (to improve the soil, accelerate the formation of humus and decompose plant residues). Application rate: 20 g per 10 l (100 ml per 10 l), consumption per hundred square meters.
How to prepare the solution correctly: dissolve the powder in 2 liters. be sure to warm, settled water, stir and leave in a dark place for 1-2 hours so that the fungus is activated. Then add water to the required volume.
If Trichodermin concentrate is used, then the entire volume is mixed immediately with water before spraying. Seedlings and seeds are processed in partial shade or shade so that the sun's rays do not fall on them.
Treatment should be carried out at air temperatures above 8 °C, on a cloudy day. Use the solution completely within 6 hours after preparation.
Security measures
Trichodermin is completely safe for humans and 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.
Drug compatibility
The biofungicide can be mixed with other drugs of similar action, with the exception of Mikosan. If you mix it and use it together with Fitosporin, Fitodoctor, Adyumax, Gaupsin and Liposam, the overall effectiveness of the products will increase.
Do not mix Trichodermin with mineral fertilizers, disinfectants and synthetic fungicides.
Storage periods and rules
Trichodermin can be stored undiluted for 2 years. Be sure to keep it in its original packaging, closed and undamaged. Observe storage conditions: at above-zero temperatures (avoid freezing), in a dry and dark place. Do not store near chemical pesticides and fertilizers.
After the storage time expires, 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 biological products based on Trichoderma harzianum. For agriculture: “Trichotsin”, “Glyokladin” in various preparative forms and “Sternifag”. Trichocin and Glyokladin can be used on private farms.
"Trichodermin" is a biofungicide known to many gardeners. It is easy to use and is used to prevent fungal infections in garden plants and to treat them if they are in an undeveloped form. It has a low consumption rate and high efficiency. It works at positive temperatures, the effect does not depend on the type of soil and variety of crop.Completely safe for treated plants and the environment.
