Phlebiopsis gigantea strain FOC PG 410.3

Phlebiopsis gigantea strain FOC PG 410.3 is a specialized biological fungicide developed for the protection of coniferous forest stands. This beneficial fungus acts as a biological agent to prevent the colonization of trees by wood-decaying pathogens, most notably the causative agent of root rot, Heterobasidion annosum.

The mode of action of this strain is based on rapid colonization and competitive exclusion. By applying the fungus to fresh tree stumps immediately after felling, it establishes a dense mycelial network that occupies the woody tissue. This creates a physical and biological barrier that prevents competitive pathogens from invading the stump and subsequently spreading to the roots of neighboring healthy trees.

It is primarily utilized in spruce and pine forestry management. The application occurs during harvesting or thinning operations, where the stump surface becomes an entry point for fungal spores. By neutralizing these entry points with Phlebiopsis gigantea, foresters can significantly reduce the incidence of root rot, which is a major cause of economic loss in forestry.

Application procedures require ensuring comprehensive coverage of the stump surface, including the bark and cambium layers. The preparation should be applied as soon as possible after the cut, preferably within a few hours, to maximize the success of colonisation. It is compatible with standard forestry equipment, making it practical for large-scale silvicultural operations.

Safety precautions for handling this biological product include wearing protective gloves, eyewear, and a respiratory mask to avoid irritation caused by spores. While the fungus itself is a natural inhabitant of forests and is non-pathogenic to healthy trees, direct exposure to high concentrations of its spores should be avoided. The agent is environmentally safe, ensuring no disruption to the delicate forest ecosystem.

• Effective prevention of Heterobasidion root rot.
