Claims23
An aqueous agrochemical microemulsion comprising
- (A) a combination of at least one pesticide A1 and at least one at least one pesticide A2, where
- (A.1) is a water-soluble pesticide and
- (A.2) is a water insoluble pesticide
- and
- (B) a mixture of at least two organosulfate surfactant components, wherein
- (B.1) at least one organosulfate surfactant is selected from compounds of formula (I)
- [R-(A)x-OSO3−]-M+ (I),
- wherein
- R is a linear radical selected from C10-C16-alkyl, C10-C16-alkenyl, or C10-C16-alkynyl, and
- X is a number selected from 1 to 10;
- and
- (B.2) at least one organosulfate surfactant is selected from compounds of formula (II)
- [Ra-(A)y-OSO3−]-M+ (II);
- wherein
- Ra is a branched radical selected from C8-C20-alkyl, C8-C20-alkenyl, or C8-C20-alkynyl, and
- Y is 0 or a number selected from 1 to 10;
- and
- wherein in formulae (I) and (II), independently from one another,
- M+ is a monovalent cation selected from the group of alkali metal ions, NH4+ and an ammonium salt of a primary, secondary or tertiary amine having a molecular weight of from 32 to 180 g/mol, or a mixture thereof;
- A is a group of the following formula (i)
- wherein
- the oxygen atom in formula (i) is bound to a carbon atom in
- R in formula (I), or respectively
- Ra in formula (II);
- and
- RA, RB, RC, and RD are selected from H, CH3, or CH2CH3, with the proviso that the sum of C-atoms of RA, RB, RC, and RD is 0, 1 or 2.
