Abstract
(EN)
Provided are a microcapsule composition capable of reducing or preventing chemical injury on useful plants by pyroxasulfone, a method for manufacturing the same, an agrochemical formulation comprising the same and a weed control method. A microcapsule composition characterized in that pyroxasulfone and a polyester block copolymer are encapsulated therein, an agrochemical formulation comprising the same and a weed control method. A method for manufacturing a microcapsule composition characterized by comprising: an emulsification and dispersion step for high-speed stirring pyroxasulfone crystal grains, a polyester block copolymer, isocyanate, an oily phase and an aqueous phase at a circumferential velocity of 10,000-50,000 mm/s and thus emulsifying and dispersing the oily phase in the aqueous phase to thereby form emulsion grains of the oily phase; and a film formation step for forming a film at least on the surface of the emulsion grains of the oily phase formed in the emulsification and dispersion step.

L’invention fournit une composition de microcapsule permettant de réduire ou de prévenir la phytotoxicité d’un pyroxasulfone sur les plantes utiles ainsi qu’un procédé de fabrication de celle-ci, une préparation de pesticide comprenant ladite composition, et un procédé de désherbage. Plus précisément, l’invention concerne une composition de microcapsule caractéristique en ce que le pyroxasulfone et un copolymère séquencé de polyester sont encapsulés, une préparation de pesticide comprenant ladite composition, et un procédé de désherbage. En outre, l’invention concerne notamment un procédé de fabrication d’une composition de microcapsule qui est caractéristique en ce qu’il inclut une étape d’émulsion/dispersion au cours de laquelle des particules cristallines de pyroxasulfone, un copolymère séquencé de polyester, un isocyanate, une phase huileuse et une phase aqueuse sont brassés à grande vitesse à une vitesse périphérique comprise entre 10000 et 50000mm/s, ainsi ladite phase huileuse est émulsionnée et dispersée dans ladite phase aqueuse, et des particules d’émulsion de phase huileuse sont formées, et une étape de formation de film au cours de laquelle un film est formé au moins à la surface des particules d’émulsion de phase huileuse ainsi formées à ladite étape d’émulsion/dispersion.
