Trichoderma viride

Trichoderma viride

Description:

Trichoderma viride is one of many species of mold. It is a filamentous fungus that is widely distributed in the soil, plant material, decaying vegetation, and wood.It is just 1-2 mm. in diameter."Mold" is a name for any fungus that produces spores asexually, by mitosis. It is the anamorph (i.e., an asexual reproductive stage) of Hypocrea rufa which is the sexual reproductive stage of the fungus and produces a typical fungal fruiting body. Trichoderma viride is a fungus and a biofungicide. It is used for seed and soil treatment for suppression of various diseases caused by fungal pathogens. It is also a pathogen in its own right, causing green mould rot of onion.

Habitat:

Spotted under a fallen Holm oak branch.

Notes:

The fungicidal activity makes T. viride useful as a biological control against plant pathogenic fungi. It has been shown to provide protection against such pathogens as Rhizoctonia, Pythium and even Armillaria. It is found naturally in soil and is effective as a seed dressing in the control of seed and soil-borne diseases including Rhizoctonia solani, Macrophomina phaseolina and Fusarium species. When it is applied at the same time as the seed, it colonizes the seed surface and kills not only the pathogens present on the cuticle, but also provides protection against soil-borne pathogens. A closely related species, Trichoderma reesei, is used in the creation of stonewashed jeans. The cellulases produced by the fungus partially degrade the cotton material in places, making it soft and the jeans looking as if they had been washed using stones.
