Biologically active preparation for protecting plants against pests, method for producing same, microcontainer for said preparation, method for manufacturing same, and method of protecting plants against pests

A method for producing a biologically active agent for crop protection against insect pests, the method comprising:

• providing microcapsules comprising a polymeric material shell and an organic solvent core, and heating the microcapsules up to 300° C. to cause perforation of the microcapsule shell and formation of at least one hole in the shell by an action of a solvent vapor pressure of the core, and adjusting a size of the at least one microcapsule shell hole by selecting a proportion of polymeric material components for the shell and varying the solvent vapor pressure, thereby producing microcontainers;
• introducing a biologically active suspension comprising entomopathogenic fungal spores and a liquid phase into the microcontainers, wherein the microcontainers are hollow receptacles each having the polymeric material shell and the at least one hole to receive the spores;
• decanting the liquid phase;
• and
• drying the microcontainers comprising entomopathogenic fungal spores.
