Abstract:
The present invention relates to a method for a preparation of a solid composition comprising the steps of a) dissolving a premix in a premix-solvent, or melting a premix, wherein the premix contains a pesticide and a nonionic, amphiphilic polyalkoxylate, b) solidifying the premix by removing the premix-solvent, or by cooling, and c) contacting the premix with at least one auxiliary. The invention further relates to a solid composition obtainable by said method; to a method for the preparation of an aqueous tank mix, in which a pesticide is present as suspended particles having a particle size below 1.0 μm, comprising the step of mixing water and a solid composition obtainable by the said method; and to a method for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insects or mites and/or for regulating the growth of plants, where a solid composition obtainable by said method is allowed to act on the particular pests, their habitat or the plants to be protected from the particular pest, the soil and/or on undesired plants and/or the useful plants and/or their habitat.
Abstract:
Subject matter of the present invention is an emulsifiable concentrate comprising a water-insoluble pesticide, an alkyl benzoate, and an amide of the formula (I) as defined herein. The invention further relates to a process for the preparation of said concentrate; an emulsion obtainable by mixing water, a water-insoluble pesticide, the alkyl benzoate, and the amide; and to a method for controlling phytopathogenic fungi and/or undesired vegetation and/or undesired attack by insects or mites and/or for regulating the growth of plants, where the concentrate or the emulsion is allowed to act on the respective pests, their environment or on the crop plants to be protected from the respective pests, on the soil and/or on undesired plants and/or on the crop plants and/or their environment.
Abstract:
The present invention relates to a composition comprising an active and a graft copolymer obtainable by free-radical polymerization of a monomer mixture comprising N-vinyllactam, vinyl ester, and an alcohol alkoxylate. It further relates to a method for preparing said composition by mixing the pesticide and the graft copolymer, and to a method for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insects or mites and/or for regulating the growth of plants.

Poly(oxyalkylene)urethane surfactants of the formula (I) R2—X—OCHN—[R1—NHCO—O—[(CH2)q—O]x—CONH—]nR1—NHCO—X—R2 (I) in which R1: an alkylene radical, a cycloalkylene radical or an arylene radical; X: —O— or NH—; R2: a linear or branched (C1-C4)-alkyl radical, monosubstituted by a group selected from: sulfo, carboxyl and [N,N-di-(C1-C4)-alkyl]amino, or disubstituted by: carboxyl; carboxyl and hydroxyl; carboxyl and mercapto; or, if X=—O—, R2 may also be defined as [R3—O—CONH—R4—NHCO—O—]mR4 in which R3: a linear or branched (C1-C4)-alkylene radical, monosubstituted by COOH, especially a —CH2—[C(COOH)(CH3)]—CH2— radical, R1 is as defined above, and R4: C2-C22-alkyl or a —CH2—[C(COOH)(CH3)]—CH2—OH radical, and m=an integer from 1 to 10; n=an integer from 1 to 7; q=an integer from 3 to 5; and x=an integer from 10 to 70; and the water-soluble or water-dispersible salts thereof are described as a solubilizer and stabilizer in active ingredient formulations.
Abstract:
The present invention relates to an aqueous co-formulation of metalaxyl, which contains: i. metalaxyl, in particular metalaxyl-M; ii. at least one organic pesticide compound PC1, which has a solubility in water of at most 1 g/l at 20° C. and a melting point in the range from 40 to 100° C.; and iii. an aqueous phase containing water and at least one surfactant; wherein the at least one organic pesticide compound PC1 is present in the form of particles suspended in the aqueous phase and where metalaxyl is essentially present dissolved in the aqueous phase and where the surfactant comprises at least one salt of an oligomer or polymer having a plurality of arylsulfonyl groups. The invention also relates to a process for preparing such formulations, which comprises the following steps: a) providing a suspension of metalaxyl in an aqueous phase containing water, at least one surfactant, which comprises at least one salt of an oligomer or polymer having a plurality of arylsulfonyl groups, b) treating the suspension until metalaxyl is essentially dissolved, to obtain an aqueous composition of metalaxyl, wherein metalaxyl is present in dissolved form; c) mixing the aqueous composition of metalaxyl obtained in step b) with an aqueous suspension of the further organic pesticide compound PC1.
