The invention relates to agricultural agents containing, A) a pesticide or a plant growth regulator, B) a copolymer made of a) a polyglycerol ether, b) one or several dicarboxylic acids and/or polycarboxylic acids whereby the polyglycerol ethers are defined by formula (I), wherein the radicals Rl, R2 and R3 are identical or different and independently represent hydrogen; (C1-C30)-alkyl is optionally substituted by 1 - 3 (C1-C4)-alkyl- or (C1-C4)-alkoxyl groups; (C2-C30)-alkenyl is optionally sulphonated and is optionally substituted by 1 - 3 (C1--C4)-alkyl- or (C1-C4)-alkoxyl groups; phenyl is, optionally, substituted by 1 - 3 (C1-C4)-alkyl- or (C1- C4)-alkoxyl groups; naphthyl is, optionally, substituted by 1 - 3 (C1-C4)-alkyl- or (C1-C4)-alkoxyl groups; groups of formulae R4R5N-(CH2) Y represent; HO-(CH2)y-; -(AO)ZH; -SO 3H; -SO3-X+; -PO3H2; - PO32-X+; -CR2-COOR'; -CR2- COO-X+; -CO-R6-COOH; -CO-R6-COO- X+; -C(R)2C(R)2C(R)2-N(R) 2; -C(R)2C(R)2C(R)2-N((AO)ZH) 2; -[CH2CH(O(AO)ZH)CH2O]n- R l; -(CH2CHR(O(AO)Z)CH2O)n-R; whereby R represents H and/or C1- - C4-alkyl; R' means H or (C1-C10)-alkyl, (C2-C30)-alkenyl which is optionally sulphonated; R4and R5 which can be identical or different, represent hydrogen, (C1-C10) alkyl, (C2-C30)-alkenyl being, optionally sulphonated or represent a group of formula -(AO)ZH; R6 represents (C1-C10)-alkene, (C2-C30)-alkenyl and are, optionally, substituted; X+ represents Na+, K+ , Ca2+ or N(R7)4+, whereby R 7 represents H or (C1-C10)-alkyl, preferably (C 1-C4)-alkyl; x represents a number from 0 - 15; y represents a number from 4 - 6; z represents a number between 0 30, preferably 1 - 5; A represents an alkene group, preferably a group -C 2H4-, -C3H6- or -C4H8-; n represents a number between 4 - 40, preferably 5 - 20, especially 10 - 20, and the indices p1, q1, r1, p2, q2, r2, p3, q3 and r3 represents numbers between 0 500 with the proviso that the compounds of formula (I) contain free OH-groups and at least one of the radicals R1, R 2 and R3 represents a carbon/hydrogen group, preferably (C1-C30)-alkyl. |
