An adequate composition of probiotic bacteria on the surface of leaves and other plant organs stimulates optimal plant development and naturally inhibits the activity of certain pathogenic organisms. Plants that have a disturbed microbiological balance often succumb to fungal diseases that attack stems and leaves as well as flowers and fruits. Application of the Ozdobne POMOC preparation improves the health of plants and stimulates them to optimal growth and development. Probiotic bacteria contained in the preparation create a microbiological barrier on the plant, which limits the place for pathogen development and at the same time favourably influences a number of important physiological processes necessary for their proper functioning.
