Patent

CA 2338569

The invention relates to multiphase aqueous suspension emulsions containing the following essential constituents a) 1 to 50 % by weight of a fungicidal active substance from the class of the benzimidazoles or benzimidazole-releasing precursors of formulae I.1 to I.4 as microsuspended solid particles; methyl 1-(butylcarbamoyl)-benzimidazole-2-yl-carbamate (I.1), methyl benzimidazole-2-yl-carbamate (I.2), 2-(2'-furyl)-benzimidazole (I.3), 2-(1,3-thia-zol-4-yl)-benzimidazole (I.4); b) an emulsion containing b1) a fungicidal active substance selected from the compounds having formulae (II.1) to (II.5) [n= 10, 11, 12 (60-70 % or 13], b2) a fungicidal active substance selected from the group of the azoles and/or b3) a benzoic acid ester of general formula (IV), wherein the substituents have the following meaning: n = a value from 0 to 3; R = C1-C8-alkyl, C6-C14-aryl, C6-C14-ary1-C1-C8-alkyl and R1 = hydrogen, C1-C8-alkyl, C6-C14-aryl-C1-C8-alkyl, halogen, C1-C6-alkoxy.

L'invention concerne des émulsions en suspension aqueuses multiphases contenant comme constituants essentiels a) 1 à 50 % en poids d'un principe actif fongicide de la classe des benzimidazoles ou des précurseurs libérant ceux-ci, sous forme de particules solides en microsuspension, ces précurseurs correspondant aux formules (I.1) à (I.4): méthyl-1-(butylcarbamoyl)-benzimidazol-2-yl-carbamate (I.1), méthylbenzimidazol-2-yl-carbamate (I.2), 2-(2'-furyl)-benzimidazole (I.3), 2-(1,3-thiazol-4-yl)-benzimidazole (I.4); b) une émulsion contenant b1) un principe actif fongicide choisi parmi des composés des formules (II.1) à (II.5), n étant égal à 10, 11, 12 (60 - 70 %) ou 13 dans la formule (II.3), et b2) un principe actif fongicide choisi dans le groupe des azoles et/ou b3) un ester d'acide benzoïque de la formule générale (IV) dans laquelle les substituants ont les significations suivantes: n vaut de 0 à 3, R représente alkyle C1-C8, aryle C6-C14, aryle C6-C14-alkyle C1-C8, R<1> représente hydrogène, alkyle C1-C8, aryle C6-C14, aryle C6-C14-alkyle C1-C8, halogène, alcoxy C1-C6.
