Trichoderma Based Products

Trichoderma Based Products


Sorbus are the UK/Ireland Distributor of Trichoderma based range of products produced by MycoSolutions based in Switzerland. MycoSolutions is a spinoff of EMPA (Swiss Federal Laboratories for Materials Science and Technology). The knowledge, creativity and scientific know-how of the company’s founders (Prof. Dr. Francis Schwarze / Reto Vincenz) and team is the foundation of its success and make MycoSolutions the unique European technology leader in the efficient application of fungi for the benefit of trees, plants, soils and wooden structures.

The range of products are based on the biological action of Trichoderma Atrobrunneum a genus of a naturally occurring, environmentally friendly species of fungus that is part of the Trichoderma Harzianum Group. It is frequently found in forests and, for example, has served for as an antagonist (natural adversary) to many wood decay fungi. In addition – for trees & plants - nutrient uptake and root growth is promoted which increases stress tolerance.


The Versatile Effects of Trichoderma atrobrunneum:

Natural Antagonist - An antagonist is understood to be a species that competes for space and resources with another species, or strain within a species. Trichoderma atrobrunneum is a natural antagonist to many wood decay fungi.

Fast Growth - Trichoderma atrobrunneum is characterised by a short life cycle and high growth rates of up to 2 cm/day in ideal conditions. By comparison, the growth rates of basidiomycetes eg. division Basidiomycota, which includes the most common wood decay fungi in trees, usually grow 1 to 2 mm/day and the life cycles range from one to several years.

Efficient Use Of Space and Food - Trichoderma atrobrunneum has a high competitive capacity for food and space, as the beneficial fungus can grow quickly and use food sources efficiently. This limits space and other resources to wood decay fungi, which are required for their development. The optimum temperature for growth and germination is 20-25 °C. The conidia (asexual spores) are pigmented green and can survive under cooler temperatures (such as in winter) by going into hibernation and then germinating again, as soon as the soil temperatures are warmer (from about 12°C).

Parasitising beneficial organism - Trichoderma atrobrunneum prefers to remain in the first 20-30 cm of the soil and litter layer, where sufficient nutrients are available. It feeds on dead organic matter, on substances secreted from roots and also obtains carbohydrates through parasitism of wood decay fungi. The hyphae of Trichoderma atrobrunneum coil around the hyphae of the host (e.g. a decay fungus). Through the secretion of lytic enzymes, the cell walls of the host fungus degrades, whilst Trichoderma atrobrunneum feeds on the cell content.

Supports Nutrient Uptake and Promotes Root Growth - Trichoderma atrobrunneum not only boosts the resistance of plants in unfavourable environmental conditions, but also increases the availability of nutrients present in the soil. In addition, various studies have shown that Trichoderma atrobrunneum stimulates the development of new roots, which supports the plant in its absorption of water and nutrients. A higher density of fine roots results in an increased water absorption capacity. In this way, Trichoderma atrobrunneum, when applied at the right time, can contribute to reduced drought stress.

Increases Stress Tolerance - In times of climate change, plants in our latitudes are suffering increasingly from drought stress. Many other stress factors affect the vitality of trees in urban areas. Trees in these locations are often pruned improperly, need to cope with limited space, an insufficient nutrient supply, soil compaction & contaminants and microbial imbalance in the soil. Trichoderma atrobrunneum supports plants suffering from these types of stress and can make a valuable contribution to the fields of tree and lawn care, as well as gardening and landscaping.

Pre-immunisation By Activation of Messenger Substances - A plant cannot initially distinguish between a symbiont and a pathogen. At first it responds equally to the infection by strengthening the cell walls and producing so-called phytoalexins (antibodies). Trichoderma atrobrunneum establishes a connection with the plants roots and communicates with the plant through signalling that enables the host to accept it as a beneficial organism. During root establishment, the beneficial fungus (also known as an endophyte) triggers metabolic and genomic changes in this plant. These changes increase the resistance of the host plant to a wide range of plant damaging microorganisms and insects.

The pre-immunisation resulting from Trichoderma atrobrunneum is achieved by intensifying the production of messengers (such as salicylic acid and jasmonic acid), which in turn can trigger the production of phytoalexins. However, the phytoalexins are only produced when a potentially harmful fungus becomes pathogenic.

More Information About Trichoderma:

  • No production of antibiotics: Therefore, our Trichoderma strain cannot cause any resistance reactions in other organisms (i.e. bacteria, fungi)
  • No production of volatile organic compounds
  • Native Trichoderma strain, that adapts to local environmental conditions
  • Nutrition: dead organic material, parasitism of other fungi
  • High germination rate, optimal at 20-25 °C
