Avengelus PRO in 7 different variations for trees and shrubs

Avengelus PRO products are conditioned against the most common soil and trunk borne wood decaying fungi (Kretzschmaria deusta, Armillaria mellea, Meripilus giganteus, Ganoderma adspersum, Laetiporus sulphureus, Inonotus hispidus, Phaeolus schweinitzii).

Conditioned in the laboratory

Currently, there are 7 different PRO products that have been conditioned in the laboratory and where upon application are immediately conditioned against the host fungus owing to a higher antagonistic potential. The already conditioned antagonist grows specifically towards the hyphae of the host fungus, coils around them and attaches to them. The hyphae of Trichoderma harzianum colonise the foreign fungal hyphae. Through the secretion of lytic enzymes, the opposing cell walls are degraded and the cell contents are used as food.

With the help of the mycoparasitism from the conditioned Avengelus PRO products, the infection burden of the tree can be managed. Since wood decay fungi develop over years, before symptoms become visable in the form of fruiting bodies, we recommend treatment with Avengelus PRO for at least a duration of 4 years to mitigate the effects of the harmful fungus.

No resistance formation

The Trichoderma strain selected in the Avengelus PRO products is environmentally friendly as it does not produce volatile substances or antibiotics. In addition to environmental compatibility, these properties also prevent the formation of resistance. The fact that most host basidiomycete fungi have very slow reproduction cycles, this does not allow for the development of resistance.

Frequency of application

Basically, it is better to use small quantities often rather than large quantities all at once. Ultimately, the goal is to achieve a balanced colonisation of roots over a longer time-frame, and thereby maintain a stable population in the soil. Trichoderma harzianum initially builds up large populations in the natural environment, which then in the course of vegetation but shrink during the course of time owing to unfavourable environmental conditions, e.g. drought. In addition, when several types of microorganisms settle on the root surface, the dominance ratios change over time. In this way, an initially strong culture can weaken significantly over time. For these reasons, the multiple application of our products is recommended. Especially with curative treatment for wood decaying fungi, we recommend 4 doses during the growing season every 4 weeks. Repeated applications mitigate the effect of the wood decay fungi by arresting its development, but this may take several years (our recommendation about 4 years) depending on the current status of the decay fungus.
