1. A composition comprising constituents (a) to (c):
(a) one or more water-soluble herbicidal active crop protectant ingredients;
(b) one or more C10-C16 fatty alcohol diethylene glycol ether sulfate salts and/or C8-C12 alkylpolyglucosides with a degree of polymerization of less than 5, and/or C12-C16 alkyl amine ethoxylates with 2 to 10 ethylene oxide (EO) units;
(c) one or more esters selected from the group consisting of (c1) to (c3):
(c1) R1COOR2, wherein R1 denotes a C5-C13 alkyl group and R2 denotes a C6-C14 alkyl group, wherein a total number of carbon atoms in R1 and R2 taken together is an integer in a range of from 14 to 22;
(c2) R3OOC—(CH2)x-COOR4, wherein R3 and R4, independent of each other, denote a C4-C12 alkyl group, and x is an integer in a range of from 1 to 6; and
(c3) (R5O)3P═O, wherein R5, independent of each other, denote a C4-C16 alkyl group, wherein a total number of carbon atoms in the three R5 taken together is an integer in a range of from 18 to 42;
and optionally one or more further constituents selected from the group consisting of constituents (d) to (h):
(d) organic solvents;
(e) water;
(f) one or more alkyl sulfosuccinate salt surfactants;
(g) one or more formulation adjuvants selected from a defoaming agent, a polydimethylsiloxane oil with silica gel, and a combination thereof, and
(h) one or more other herbicidal active crop protectant ingredients and/or herbicide safeners, wherein the one or more other herbicidal active crop protectant ingredients are different than the one or more water-soluble herbicidal active crop protectant ingredients;
wherein a total amount of the constituent (a) to a total amount of the constituent (c) is in a range of from 60:1 to 2:1, and
a total amount of constituent (a) to the total amount of constituent (b) is in a range of from 10:1 to 1:6, and wherein the composition exhibits improved rainfastness as compared to a composition including components (a) and (b), and optionally one or more further constituents selected from the group consisting of constituents (d) to (h), but not containing one or more esters selected from the group consisting of (c1) to (c3).
