Mixed microorganisms

The support from TRICHODERMA with the power of MYCORRHIZA

COVENANT is a product developed and patented (WO/2017/068218) by ATENS for seed treatment. COVENANT incorporates an unique technology which allows our fungi spores and bacteria to adhere to the surface of seeds in an eectible and stable way.

COVENANT contains strains of the exclusive microorganisms of ATENS, selected by its effectiveness and benefits in the main cultivations, either extensive or green legumes.

Rhizoglomus irregulare BEG72: the mycorrhiza with the highest number of scientific publications worldwide.


Stimulates rooting and root growth by modifying root architecture by increasing precursors of auxins.
Increases the availability of minerals such as iron through increased production of siderophores.
Also, the increase in glycolic acid in root exudate has been detected, a soil acid that acts as a chelating agent for the less soluble minerals (phosphorus, iron, manganese and zinc).
Induces higher cholophyll density, indicative of better nutrition nitrogen and conferring plants greater tolerance to photoinhibition.


Rhizoglomus irregulare: 230 espores/g
Funneliformis mosseae: 230 espores/g
Trichoderma koningii: 3 x 10⁸ UFC/ g
Rhizosphere bacteria (PGPR): 4 x 10⁷ UFC/ g

Metabolomic analysis of bio-effectiveness:

Proven results using the latest technology available

Metabolomic is the scientific study of the whole metabolite content and their complex relationships. It makes possible to know the regulation mechanisms of the plants and to understand its development during their life cycle. Results have demonstrated that COVENANT:

• Enhances the rooting process and root growth modifying root architecture though the increase of auxin precursors.
• Increases the availability of minerals as the iron by the production of siderophores.
• Besides, it has been showed the increased glycolic acid concentration in root exudates, a soil acidifier that acts as chelating agent of poor soluble minerals (phosphorus, iron, manganese and zinc).
• Induces higher chlorophyll density, indicator of a better nitrogen nutrition and higher tolerance to photoinhibition.
