METHOD FOR PRODUCING COMPOSITION FOR PLANTS TREATMENT (VARIANTS) Russian patent published in 2005 - IPC

FIELD: agriculture.

SUBSTANCE: invention relates to technology for producing agent used for biological protection of plants and concerns a method for producing composition used for treatment of plants. Method involves hydrolysis of biomass of micromycetes of family Mortierella or Pythium, its extraction with a liquid extractant taken among group including lower alcohols, saturated or unsaturated hydrocarbons comprising up to 10 carbon atoms in their molecule, their halogen-derivatives, inert gases, nitrogen, nitrous oxide, carbon dioxide and their mixture, separation of extract and addition to extract inactive components to obtain the end product. In hydrolysis process pressure value in reaction mixture is dropped periodically to value providing boiling up extractant and then pressure is increased to the parent value. Invention provides reducing energy consumptions and intensifying the process.

EFFECT: improved producing method.
