Pesticide formulations containing alkoxylated amines

A method for controlling weeds, said method comprising contacting the weeds with a composition comprising:

• a) at least one pesticide and
• b) at least one compound selected from formula I
• R1—N{(A1O)rH}—(CH2)3—N{(A2O)sH}—[(CH2)3—N{(A3O)tH}]a—(CH2)y—[N{(A4O)uH}—(CH2)3]b—N{(A5O)vH}—(CH2)3—N{(A6O)wH}—R2 (I)
• in which
• R1 and R2 are, in each case independently of one another, a linear or branched alkyl or alkenyl residue with 6 to 30 carbon atoms,
• A1 to A6 are, in each case independently of one another, a group of the formula —C2H4— or —C3H6—,
• r, s, t, u, v and w are, in each case independently of one another, a number from 1 to 400,
• the sum of the numbers r, s, t, u, v and w has values from 10 to 600,
• a and b are, in each case independently of one another, a number from 0 to 10, and
• y is a number from 2 to 10,
• the compound of formula I also including derivatives in which a fourth residue is bonded to one or more nitrogen atoms, said fourth residue is chosen from H and linear or branched alkyl groups with 1 to 6 carbon atoms, and wherein counterions of these derivatives are selected from the group consisting of chloride, bromide, iodide, fluoride, sulfate, hydrogensulfate, carbonate, hydrogencarbonate, phosphate, mono- and dihydrogenphosphate, pyrophosphate, metaphosphate, nitrate, methyl sulfate, phosphonate, methylphosphonate, methanedisulfonate, methanesulfonate, ethanesulfonate, and mixtures thereof, or from anionic compounds of the formula R6SO3− and R7SO4− or R6COO− in which R6 and is a linear or branched C8-C20 alkyl, and R7 is a linear or branched C8-C20 alkyl, or a C7-C18 alkylphenyl,
