METHOD AND PROCEDURE FOR OBTAINING MICRO BIOCAPSULES OF NATURAL PYRETHRINS WITH HIGH STABILITY

摘要

The present invention describes a procedure for obtaining microbiocapsules of one or more pyrethrins as active substance, and is framed in the field of biopesticide production technique. Natural pyrethrin is a broad spectrum insecticide extracted from the flowers of the plant of the genus Chrysasnthemun and is easily decomposed by air and light. The present invention increases the stability of pyrethrins, being effective for a longer time than other solutions of the state of the art. The method and procedure comprises the following steps; a first oil phase, a second phase of mixture emulsion and a third encapsulation phase. The result is the obtaining of pyrethrin microbiocapsules with a size between 0.5 to 5 microns, with greater stability. The process does not reduce the insecticidal capacity of pyrethrins.
