Abstract (en)

[origin: WO9622159A1] This invention relates to the microencapsulation of various materials, in particular pesticidal materials, to produce both wet and dry formulations. In particular, the invention relates to encapsulating such materials by incorporating a PVA into an interfacial polycondensation system for producing microcapsules, and subsequently spray drying the resulting microcapsules in the presence of the PVA, and optionally a further quantity of PVA which may be the same or different from the one adopted in the microencapsulation step, so that the encapsulated product can be diluted in water, in order to produce aqueous pesticidal compositions, which can be applied by conventional spray techniques.
