Abstract: 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.

Abstract: The present invention relates to an isolated strain of Bacillus subtilis (IAB/BS/03) deposited at the DSM German Type Culture Collection under Access No DSM 24682, or a mutant of said strain, and also deposited at the Spanish type culture collection under Access number CECT 7254, the property of the company filing the patent, in which said strain and/or the mutant thereof exhibits antifungal and antibacterial activity, with a profile of action different from that of other strains of Bacillus subtilis and with much greater potency in terms of the capacity thereof to act as a field biological control agent. The invention also includes methods for preventing and treating fungal and bacterial diseases in plants using said bacterial strains or supernatants containing antibiotics or pure antibiotics obtained from said bacterial strains, in which said antibiotics are contained in a composition.
