Abstract
The present invention relates to novel water-dispersed agrochemical formulations, for example water-based suspension concentrates, of active agrochemical ingredients, comprising a penetrant and a thickener from the class of the anionic polysaccharides which contains, as the repetitive base unit in the main chain, four sugar molecules (glucose, glucuronic acid, glucose, rhamnose), to a process for producing these formulations and to the use thereof for application of the active ingredients present.
Claims5
A water-dispersed agrochemical composition, comprising
- (a) 1 to 60% by weight of at least one active agrochemical ingredient, wherein the at least one active agrochemical ingredient is selected from the group consisting of spirotetramat, tebuconazole, prothioconazole, tembotrione, thiacloprid, fluopicolide and imidacloprid, and wherein the at least one active agrochemical ingredient is a solid at room temperature;
- (b) 1 to 50% by weight of at least one penetrant, wherein the at least one penetrant is obtained by ethoxylating rapeseed oil, the degree of ethoxylation being between 50% by weight and 80% by weight;
- (c) 0.005 to 1% by weight of a at least one thickener, wherein the at least one thickener is an anionic polysaccharide which contains, as the repetitive base unit in the main chain, four sugar molecules containing glucose, glucuronic acid, glucose, and rhamnose;
- (d) 1 to 20% by weight of at least one nonionic or at least one anionic surfactant;
- and
- (e) 0.1 to 25% by weight of one or more additives selected from the group consisting of foam inhibitors, preservatives, antioxidants, spreaders, and dyes;
- wherein the composition is the form of a suspension concentrate.
