Patent

CA 2268619

The invention relates a concentrated liquid fungicidal composition comprising a fungicidally acceptable carrier and/or surface active agent and (a) at least one compound of formula I, (see formula I) in which R1, R2, R3 and A are as defined in the specification, or one of the salts or addition products thereof, which exists in solubilized form; and (b) one or more additional fungicidal active ingredients, which exist as a suspension of fine particles; (c) a solubilizing agent; and (d) a dispersing agent, which has the capability to adsorb irreversibly on the surfaces of hydrophobic particles suspended in water or polar organic solvents. The invention relates furthermore to concentrated fungicidal compositions comprising a fungicidally acceptable carrier and/or surface active agent and synergistically effective amounts of at least one compound of formula I, and chlorothalonil and/or kresoxim-methyl, as well as methods of using a combination of synergistically effective amounts of at least one compound of formula I, and chlorothalonil and/or kresoxim-methyl in the presence of a solubilizing agent to control various fungi, especially on cereal crops such as wheat.

L'invention a trait à une composition fongicide liquide concentrée, comportant un excipient acceptable, compte tenu de la fonction fongicide, et/ou un agent tensioactif et : a) au moins un composé de formule I (voir formule I), où R1, R2, R3 et A sont tels que définis dans les spécifications, et un des sels ou des produits d'addition de ce composé, qui existe en solution; b) une matière active fongicide ou plus, qui existe sous la forme de fines particules en suspension; c) un agent de solubilisation; d) un agent de dispersion ayant la capacité de s'absorber de manière irréversible sur les surfaces des particules hydrophobes en suspension dans l'eau ou des solvants organiques polaires. L'invention concerne également des compositions fongicides concentrées comportant un excipient acceptable, compte tenu de la fonction fongicide et/ou un agent tensioactif ainsi que des quantités synergiquement efficaces d'au moins un composé de formule I, du chlorothalonil et/ou du krésoxim-méthyle, de même que des méthodes fondées sur la combinaison de quantité synergiquement efficaces d'au moins un composé de formule I et de chlorothalonil et/ou de krésoxim-méthyle en présence d'un agent de solubilisation, comme moyen de lutte contre divers champignons, surtout dans les cultures de céréales comme le blé.
