Active Substance

Pythium oligandrum is a microorganism that taxonomically belongs to the kingdom Chromalveolata and the family Oomycetes. Charles Drechsler (1943) was the first to describe Pythium oligandrum as the mycoparasite of the wide range of phytopathogenic fungal microorganisms. During the 1970’s, Dr. Dáša Veselý focused his research on development of Pythium oligandrum for plant protection uses. In the 1990’s, the company Biopreparáty, spol. s r.o. succeeded to formulate, register and commercialize Pythium oligandrum, strain M1, as the biological fungicide.

Mode of Action 

Mycoparasitism

Pythium oligandrum  is able to attack directly a plant pathogenic fungus and/or an oomycete. A direct mycoparasitism is a key component of the antagonistic process.  Cell-wall-degrading enzymes produced by  Pythium oligandrum are able to decompose hyphae of plant pathogens.

Induced resistance

Pythium oligandrum is able to produce elicitor-type of metabolites (oligandrin). They stimulate a number of physical and biochemical defense mechanisms in plants, restricting pathogen penetration and development in the host tissues.

 

Growth stimulation

Pythium oligandrum is able to produce auxin-like compounds, with plant growth-stimulating activity (tryptamine - TNH2).
