Title (EN) MICROENCAPSULATED SOLID PESTICIDES
(FR) PESTICIDES SOLIDES MICROENCAPSULES
Abstract: front page image
(EN)A microcapsule characterized by comprising a solid pesticide as a core material coated with a wall material which is a resin formed by polycondensation of a sparingly water-soluble melamine-formaldehyde resin type prepolymer (said sparingly water-soluble melamine-formaldehyde resin type prepolymer dissolves 2000 g or less of water therein per 100 g of solid component of the prepolymer at +25 °C) in the presence of a dispersant which is a condensation product of naphthalenesulfonic acid and/or alkylnaphthalenesulfonic acid and formaldehyde or a salt thereof, a method for producing said microcapsule, and a method for applying said microcapsule are disclosed.
(FR)La présente invention concerne une microcapsule caractérisée en ce qu'elle comprend un pesticide solide comme matière centrale, enrobée de matière de paroi constituée de résine formée par polycondensation d'un prépolymère de type résine mélamine-formaldéhyde modérément hydrosoluble (ce prépolymère de type résine mélamine-formaldéhyde modérément hydrosoluble étant dissous dans 2000 g d'eau ou moins par 100 g de composant solide du prépolymère à +25 °C), en présence d'un dispersant qui est un produit de condensation d'acide naphthalènesulfonique et/ou d'acide alkylnaphthalènesulfonique et de formaldéhyde ou de sel de celui-ci. En outre, cette invention concerne un procédé de production de cette microcapsule, et un procédé d'application de cette microcapsule.
