Green Trump Card in Your Hand

KANGER^® is registered as an auxiliary herbal product. Its beneficial side effects include the action of bacterial metabolites against fungal pathogens. This product contains living bacteria of the species Bacillus amyloliquefaciens (strain FV08-10 in the Culture Collection of Microorganisms Brno; proprietary to MONAS Technology s.r.o.), which have been shown to produce a number of plant health promoting substances, including these with antifungal effects. In the case of apple orchards, the application is particularly suitable for the treatment of fungal diseases such as powdery mildew (Podosphaera leucotricha) and apple scab (Venturia inaequalis), both on the leaves and the fruits.

Mode of action

KANGER^® consists of a cultivation medium containing bacteria in their encysted form (larger proportion), active bacterial cells, and a mixture of their metabolic products. While the active cells and metabolites guarantee a rapid onset of positive effects, the presence of bacterial spores ensures the durability of the product, as well as its continuous action following the application.

Bacillus amyloliquefaciens contained in the product belongs to the rhizosphere Gram-positive bacteria, for which the soil near the plant roots represents their primary habitat. Nevertheless, it also thrives on leaves and fruits, where it preferentially colonises the furrows lining the epidermal cells, and it prospers especially in times of increased humidity. As such, it is a contact antagonist of pathogenic fungi, which enter the plant bodies through the furrows in their skin, and are most active when wet. The overall effect is preventive in that bacterial cells occupy space that would otherwise be used by fungal spores for their own germination.

Whether we are talking about compounds contained in the medium, substances produced by the bacteria after application, or preventive action based on competition for space, in all cases the growth of the mycelium of pathogenic fungi is inhibited and the development of their spores is suppressed.
