General Information: (Polyversum is for the stimulation of plant growth, the enhancement of plant strength and the prevention of fungal attack. Polyversum mobilizes plant defense mechanisms, increasing plant resistance to pathogenic fungal attack, increasing rate of growth and increasing overall crop strength and yield.) (Polyversum is a (microbial seed dresser) (microbial preparation) that protects (field) crops against soilborne fungal pathogens, promotes plant growth**, enhances plant strength and induces a plant defense reaction against soil and airborne pathogenic fungi.) Polyversum can be applied as a seed dressing, pre-plant soak, overhead spray or soil drench, or irrigation application.
Mode of Action: The active ingredient, Pythium oligandrum DV 74, colonizes (the surroundings of treated and sown seeds) (the rhizosphere of treated plants). Because of its strong mycoparasitic and competitive abilities, the active ingredient suppresses the growth and antagonistic effects of many soilborne pathogenic fungi, which cause damping-off and seed and root rots such as Phytophthora, Rhizoctonia, Fusarium spp., etc. The active ingredient also induces a defense reaction in the newly emerged plant through the stimulation of phytohormones that trigger the plant's resistance mechanisms against diseases. Pythium oligandrum DV 74 does not produce any antibiotics and therefore is considered a true plant growth promoter for the induction of plant resistance.

Integrated Pest Management: Integrate Polyversum into an overall disease and pest management strategy whenever fungicide use is necessary. Follow practices known to reducedisease development. Consult local agricultural authorities for specific IPM strategies developed for your crop(s) and location.
