Formulation: culture liquid containing spores and mycelium - antagonist Trichoderma lignorum, and produced by the fungus culture during culturing production of biologically active substances.

It recommended for protection of plants against a wide range of fungal and bacterial diseases.
Fungus Trichoderma lignorum suppresses the development of phytopathogen direct parazitirovaniem, competition for substrate isolation of enzymes, antibiotics (gliotoksin, viridin, Trichoderma et al. ), And other biologically active substances which inhibit the growth of many types of pathogens and inhibit their reproductive ability.
Due to the high biological activity of the fungus Trichoderma lignorum substrate develops quickly and actively participates in the decomposition of organic compounds, the processes of ammonification and nitrification, phosphorous enhancing mobilization and potassium enriching soil nutrients mobile forms.
Trichoderma lignorum secreted biologically active substance at a particular concentration promote plant growth and development, increasing their resistance to disease.
In the soil fungus Trichoderma lignorum develops on various plant residues rich in cellulose, resting on the mycelia and fruiting bodies of phytopathogens. The temperature optimum for the development of Trichoderma lignorum in culture 24 . . . . . + 28 ° C, the maximum temperature is 31 . . . . . + 33 ° C, minimum 12 . . . . . + 18 ° C. In vivo at an optimal moisture and soil aeration properties antagonistic fungus Trichoderma lignorum well occur even at temperatures close to 20 ° C. The fungus is an aerobe, which explains its rapid development in well - aerated soil rich in organic matter. The fungus is able to grow over a wide pH range of soils, but its antagonistic properties are manifested most efficiently in the soil with a pH of 5 - 7.
The fungus Trichoderma lignorum inhibits pathogens transmitted through the soil and crop residues. He is a parasite on the sclerotia of the fungus Sclerotinia sclerotiorum, psevdosklerotsiyah fungus Rhizoctonia solani, is active against fungal genera Alternaria, Ascochyta, Botrytis, Colletotrichum, Fusarium, Helminthosporium, Pythium, Phoma, Phytophthora, Verticillium. The positive results from the use of Trichoderma in the fight against fungi of the genus Cytospora, causing cancer and drying of shoots stone rocks.

• The active substance - mushrooms Trichodermaharziannum VIZR - 18 and a set of metabolites (useful soil microflora).

• Effectively inhibits fungal diseases and protects against infection :

· Root rot (pitioznye, rizoktonioznye, Fusarium);

· Withering of various etiology;

· Leaf and stem diseases (askohitoz and anthracnose, blight and gray mold).

• Mechanism of action: the fungus forms in the soil is well - developed mycelium, reproduce by spores. A rival and antagonist of pathogenic fungi, showing towards them biotrophic properties. Its high activity leads to stopping the growth of pathogenic fungi lysis and death of the mycelium.

• The list of protected crops: cucumber protected and open ground, tomatoes protected and open ground, potatoes, wheat, sugar beet, apple, grapes, black currants and gooseberries, strawberries, protected ground roses and ornamental trees and shrubs, seedlings flower crops, room flower culture.
