FIELD: agriculture, pesticide. ^ SUBSTANCE: invention relates to technology for producing agent used for biological protection of plants and concerns a method for producing a pesticide composition. Method involves extraction of micromycetes of family Mortierella or Pythium biomass in electrostatic field of high intensity with a liquid extractant taken among group comprising 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 mixtures, separation of extract and addition to extract inactive component to obtain the end product. In the extraction process pressure value in extractive 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 extraction process. ^ EFFECT: improved preparing method. ^ 41 cl |
