Abstract
The present invention relates to the use of surface-reacted calcium carbonate-containing minerals and/or surface-reacted precipitated calcium carbonates as solid particulate carriers to enhance the efficacy of agrochemical compounds loaded onto of said carriers.
Claims24
A composition comprising:
- (a) a particulate solid carrier comprising a surface-reacted calcium carbonate that is a reaction product of calcium carbonate in an aqueous medium with carbon dioxide and at least one water soluble strong acid or medium strong acid, wherein the carbon dioxide is formed in situ and/or supplied from an external source;
- and
- (b) at least one agrochemical compound loaded onto the particulate solid carrier;
- wherein the at least one agrochemical compound is a fungicide selected from the group consisting of benalaxyl, kiralaxyl, furalaxyl, metalaxyl, mefenoxam, oxadixyl, ofurace, dimethomorph, flumorph, pyrimorph, benthiavalicarb, iprovalicarb, valifenalate, and mandipropamid.
