Abstract

The present invention relates to liquid suspension concentrate formulations for plant protection comprising: 2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1-(2H)pyrimidinyl]-4-fluoro-N-[[methyl(1-methylethyl)amino]sulfonyl]benzamide in the form of the crystalline anhydrate; at least one diluent selected from: hydrocarbon solvents having a boiling point of at least 100° C.; and C1-C8-alkyl esters of C8-C26-fatty acids, mono- and di-C1-C4-alkyl amides of C8-C26-fatty acids; at least two different non-ionic surfactants selected from poly-ethoxylate-co-C3-C4-alkoxylates of C3-C20-alkanols, polyethoxylates of C8-C22-alkanols, polyester-polyoxyethylene block copolymers, polyethoxylates of mono-, di- or tristyryl phenols and polyethoxylates of vegetable oils; and at least one anionic surfactant selected from C1-C16-alkylarene sulfonates.
