Profile: Biopreparaty Ltd. offers products for biological preparations on plant protection. We develop bio-preparations in plant protection, medical cosmetics, fungi-static preparations in building industry and veterinary preparations. Our research area focuses on bio-preparations for some chemical substances and pharmaceutical forms of treatment. The active ingredient of biopreparation Polyversum is fungi-like organism Pythium oligandrum. The Pythium oligandrum colonizes the rhizosphere of treated plants. Because of its strong mycoparasitical and competitive abilities, suppress the growth and antagonistic effects of many soil-borne pathogenic fungi causing damping off and rots of roots and plants bottoms. ythium oligandrum also induces defense reaction in the plant, through stimulation of the phytohormones, which are involved in the resistance mechanisms of the plant against diseases. Pythium oligandrum does not produce any antibiotics and therefore is considered a true plant growth promoter for the induction of plant resistance.
