Trichoderma are saprophytic fungi that feed on organic matter. They are able to rapidly colonize the rhizosphere and can substantially improve plant development and health.

Trichoderma as a biostimulant

From the application of Trichoderma in the soil, it quickly colonizes the rhizosphere of the plant, leaving other non-beneficial fungi without resources or space.
Helps plants cope with different types of stress.
As a result, it is capable of improving crop growth, contributing to the improvement of soil fertility and vitality.

How does Trichoderma work?

It is an indispensable for agriculture:

Promotes plant growth

particularly rooting through the emission of volatile organic compounds and the synthesis of auxins.

It contributes to the best plant nutrition

through the secretion of siderophores for iron uptake.


Trichoderma has great biostimulant capacities, stimulating the root system with the following results:

Increased uptake of nutrients, especially iron through the production of siderophores.

Promotes crop growth, increasing its vigor.

Improves soil fertility.

Increases tolerance to root stress situations.

Own production technology

Trichoderma Atens is produced by our own method using solid medium bioreactors.
Such bioprocess, perfected with patented solid fermentation technology, optimizes its potential by guaranteeing:

– Homogeneous, mature and stable spores, which ensure maximum performance in the field.
– The extensive process of obtaining spores using a reactor in a solid medium allows optimal maturation of the spores as well as their dormancy until the moment of application.

Both factors allow for a longer shelf life of the product and keep its vitality intact until field release.

Metagenomics and Genomics in the application of Trichoderma

After the application of Trichoderma in the soil, rapid growth occurs, reaching a maximum population a few days later. From this moment on, its population decreases and approximately after a month a concentration of Trichoderma similar to that prior to the application is reached.

Trichoderma DNA Isolation

These data have been corroborated by isolating Trichoderma DNA from soil and quantifying it using PCR tests carried out in the Atens laboratory, NGAlab.

Soil Contribution

Due to this dynamic, Trichoderma management includes its contribution to the soil in limited but regular concentrations distributed during the growing season, ensuring adequate establishment for plant stimulation.

FAQS Atens. Any questions?

What makes Trichoderma Atens different?

Atens combines an exhaustive strain selection process with its own technology to reproduce microorganisms. In-house production process using a solid state reactor guarantees the highest quality of homogeneous, mature and stable spores. With this method, the concentration of colony-forming units (CFU) is higher and soil colonization is rapid and immediate after application, requiring fewer applications during the campaign. This process makes the cell walls of the spores sufficiently thick and well developed, allowing a longer shelf life of the product and its maximum vitality at the time of application.

Under what legislative framework are Atens Trichodermas marketed?

At Atens we currently have two different Trichoderma species. Trichoderma atroviride strain AT10 is in the final stages of phytosanitary registration in annex I and III both in Europe and in the United States. This strain will not be marketed until the registration process is complete. Trichoderma koningii TK7 is registered in Spain under Real Decreto 506/2013 within the group of Non-Mycorrhizal Microorganisms in the Fertilizer Registry of the Ministry of Agriculture, Livestock and Fisheries.

How often should I apply Trichoderma?

The Atens trichoderma must be applied distributed throughout the campaign. To achieve a sustained biostimulant effect, the best management strategy includes the frequent use of limited concentrations. The number of applications varies depending on the crops and the length of their cycle. For more information, do not hesitate to contact our technical service.

Is it compatible with other microorganisms?

The Trichoderma produced in Atens is 100% compatible with the other microorganisms developed by the company (mycorrhizae and/or bacteria). In the case of combination with mycorrhizae, a faster colonization of the root by the latter has been observed due to the rooting effect of Trichoderma. Clarification: These synergies are only guaranteed between products developed by the company.

Is Trichoderma compatible with commonly used active ingredients?

The Atens technical department has information about the compatibility between our Trichoderma strains and the main active ingredients that include fungicides, herbicides and insecticides. We can advise our clients on the convenience of applying Trichoderma and the need for a safety period between the application of the different treatments required. In this way we ensure the full vitality of the inoculum without interference with these compounds.
