Abstract:
Microcapsule having a shell and a core, wherein said core contains a non-aqueous liquid, said non-aqueous liquid being one or more liquid (at 21° C.) active substances or one or more active substances dissolved in a solvent S, solvent S being immiscible with water, and wherein said shell contains i) at least one protein PR that is overall negatively charged, ii) at least one polysaccharide PS that is overall positively charged, and iii) optionally an inorganic salt IS capable of crosslinking components protein PR and polysaccharide PS via formation of non-covalent bonds.
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:
Microparticle, wherein said microparticle contains one or more active substance, said one or more active substance being water immiscible, wherein said one or more active substance is liquid (at 21° C.) or dissolved in a non-aqueous solvent S that is immiscible with water, and wherein said microparticle contains i) at least one phospholipid PL, ii) at least one sterol ST, iii) at least one at least one polypeptide PP, iv) optionally at least one polysaccharide PS that is overall positively charged, and v) optionally an inorganic salt IS capable of interacting with at least one of the components i) to iv) via formation of non-covalent bonds.
Abstract:
A granular composition comprising a pesticide, 0.1 to 10 wt % of a nonionic amphiphilic polyalkoxylate, at least 20 wt % of a solid water-soluble anionic dispersant, at least 5 wt % of a sugar, which is a mono- or disaccharide, or a mixture thereof, and a polyvinylpyrrolidone is provided. Methods for the preparation of the granular composition including the steps of (i) providing an aqueous suspension comprising the pesticide, the polyalkoxylate, the dispersant and the sugar, (ii) drying the aqueous suspension, and (iii) granulating the aqueous or dried suspension, and wherein the polyvinylpyrrolidone is added in step (i) and/or step (iii) are further provided. Methods for controlling at least one of phytopathogenic fungi, plant growth, attack by insects or mites, and/or for regulating the growth of plants, wherein the composition is allowed to act on the particular pests, their habitat, the undesired or useful plants, and/or the soil are further provided.
Abstract:
The present invention relates to a method for preparing an emulsifiable granule comprising the steps of a) emulsifying water with a solution of a pesticide in a water-insoluble solvent, b) contacting the emulsion resulting from step a) and a solid dispersant containing a water-soluble polycarboxylate and a water-soluble anionic surfactant, and c) extruding the paste resulting from step b). The invention further relates to emulsifiable granules containing a water-insoluble solvent, a pesticide, which is dissolved in the water-insoluble solvent, a water-soluble polycarboxylate, and a water-soluble anionic surfactant.
