METHOD OF PRODUCING A SOLID PREPARATION FOR PROTECTION OF CULTIVATED PLANTS, AND SOLID PREPARATION

摘要

FIELD: chemical protection of plants. SUBSTANCE: method consists in common extrusion of an active ingredient with polyvinylpyrrolidone followed by cooling of the extrudate to brittleness state and its further disintegration. The thus obtained chiefly grained preparation can be used as it is or pressed into pellets and agglomerated into bigger grains, each of these forms being rapidly dispersed upon water dilution and possessing biological activity equal to that of emulsified concentrates. The latter allows one to avoid use of undesired solvents when preparing claimed preparations. EFFECT: improved environmental condition.
