An aqueous agrochemical active-ingredient composition, comprising (a) one or more water-soluble agrochemical active ingredients, (b) one or more alkyl glucamides of formula (I), wherein R1 represents a linear or branched alkyl group comprising 5 to 9 carbon atoms, R2 represents an alkyl group comprising 1 to 3 carbon atoms, (c) represents one or more silicone-based defoamers selected from the group of linear polydimethylsiloxanes and (d) water. For the defoamer, the ratio of dynamic surface tension at a concentration of 2.0 g/l and a surface age of 20 ms in 20 wt% aqueous propylene glycol to the dynamic surface tension under identical conditions in 20 wt% aqueous dipropylene glycol is greater than 1:10 and the ratio of the dynamic surface tension at a concentration of 2.0 g/l and a surface age of 20 ms in 20 wt% propylene glycol to the dynamic surface tension at a concentration of 10.0 g/l and a surface age of 20 ms in tap water is greater than 1:10. Said aqueous agrochemical active-ingredient composition is suitable for manufacturing low-foam application forms of agrochemical active ingredients. |
