Trichoderma atroviride 77B

The mechanism of pathogen suppression is based on mycoparasitism: the fungus locates the hyphae of harmful organisms, coils around them, and releases specific enzymes (chitinases and glucanases).

This strain also exhibits pronounced antibiotic activity, synthesizing volatile and non-volatile metabolites that inhibit the development of phytopathogens in early stages.

In addition to directly destroying pests, Trichoderma stimulates the plant's immune system by activating defense proteins and promoting the development of a more robust root system.

Competition for nutrients and space in the root zone deprives pathogenic fungi of the opportunity to establish themselves and initiate the infection process.

Formulations based on this strain are used to combat a wide spectrum of soil-borne and seed-borne infections affecting vegetable, cereal, and ornamental crops.

Primary application targets include the suppression of Fusarium species, which cause fusarium wilt and various types of root rot.

It is effective against pathogens of gray mold (Botrytis cinerea), which affects fruits, leaves, and shoots under conditions of high humidity.

It is used to reduce the risk of late blight, early blight (alternaria), and pythium rot, which frequently afflict seedlings in greenhouses.

The product shows high efficacy during pre-sowing seed treatment and soil irrigation, preventing seedling damping-off.

Application rates depend on the method of use: for seed treatment, a suspension with a high concentration of spores is typically utilized.

When applied to soil or as a root drench, the product is used during periods of active growth, provided the substrate temperature is between +15 and +25 degrees Celsius.

The cumulative effect of the biological agent in the soil allows for prolonged protective action throughout the entire growing season.

There are practically no waiting periods before harvest, as the active substance is fully biodegradable and non-toxic to warm-blooded animals.

Regular re-applications are recommended at the first signs of infection to maintain the population of the beneficial fungus at an effective level.

The use of this product is strictly restricted when chemical fungicides are employed, as they suppress the viability of the beneficial microorganism.

It is important to avoid exposing the working solution to direct sunlight during application, as ultraviolet radiation negatively affects spore viability.

Efficacy is reduced in extremely acidic or alkaline soils, as well as during sharp temperature fluctuations that slow down the metabolism of Trichoderma.

The product cannot be mixed in tank mixtures with strong oxidizing agents, disinfectants, or preparations containing copper or sulfur.

Personnel are required to use basic personal protective equipment to prevent potential allergic reactions from inhaling spores.
