Under the supervision of Prof. Frahm from the University of Bonn, several native moss species were tested on fungus-infected crops such as tomatoes, cucumbers, peppers or wheat. One particular species of liverwort was found to have a convincing plant-strengthening effect.

Liverwort is a natural product which is quickly biodegradable. In contrast to fungicides such as copper broth, no residues remain in the soil. There are also no known side effects.

The total extract of mosses contains a "cocktail" of the most diverse chemical compounds. This is where the synergetic effects of these combinations of active ingredients play a role. The cocktail stimulates an increased resistance of the treated plants against a variety of fungi and other pests.

The investigations were preceded by the observation that the mosses growing in damp conditions are not themselves attacked by fungi and are also avoided by voracious snails and beetles. But mosses can do even more: North American Indians used them to make antiseptic wound dressings, and the Canadian Red Cross recalled this traditional knowledge and used moss compresses for the wounded during World War I.
