FIELD: agriculture.
SUBSTANCE: biological preparations are produced by means of depth cultivation of antagonist fungi from Trichoderma or Gliocladium kinds for 20-48 hours till biomass is produced in vegetative form with further addition of substance, which assists in spore formation. Right after production the preparation has the following composition (wt %): biomass of antagonist fungi - 10-99; source of carbon and energy - not more than 85; acid up to pH of 2.0-5.0 - not more than 5, inhibitor of cell metabolism - not more than 0.05, sticker-disperser - not more than 10, or biomass of antagonist fungi - 10-90; source of carbon and energy - not more than 50, source of nitrogen - not more than 1, sorbent - 10-90, acid up to pH of 2.0-5.0 - not more than 5, sticker-disperser - not more than 10. In process of preparation storage, biomass of antagonist fungi changes from vegetative form into spore form, and as a result, preparation is preserved.
EFFECT: inventions makes it possible to produce preparations, in process of storage of which with air access activity of preparations is preserved for at least 6 months.
