Abstract

Abstract Flowable herbicidal compositions which contain an active component combination of at least one chlorotriazine and a chloroacetanilide form stable aqueous dispersions if the surfactant component of the composition consists of an anionic surfactant from the series of the mono- or diphosphoric acid esters of phenol polyglycol ethers and a mixture of two non-ionic surfactants from the series of the alkoxy, alkanoyloxy or phenol polyglycol ethers which differ by at least one glycol unit.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 343 words
A flowable herbicidal composition having at least one solid disperse phase and a continuous aqueous phase comprising (a) combination of (i) from 10 to 50% by weight of at least chlorotriazine of the formula: ##STR5## wherein R 1 is alkyl of 1 to 4 carbon atoms, R 2 is hydrogen or alkyl of 1 to 4 carbon atoms, and R 3 is cycloalkyl of 3 or 4 carbon atoms, alkyl of 1 to 4 carbon atoms, or alkyl of 1 to 4 carbon atoms substituted with methoxy or cyano; and (ii) from 10 to 50% by weight of at least one chloroacetanilide of the formula ##STR6## wherein each of R 4 and R 5 , independently of the other, is methyl or ethyl and R 6 is alkynyl of 3 or 4 carbon atoms, alkyl of 1 to 3 carbon atoms, or alkyl of 1 to 3 carbon atoms substituted with alkoxy of 1 to 4 carbon atoms, ethoxy carbonyl, or pyrazolyl; (b) a surfactant system consisting essentially of (i) from 1 to 10% by weight of at least one anionic surfactant of the formula: ##STR7## wherein A is ##STR8## in which R 7 is hydrogen, alkyl of 3 to 10 carbon atoms or styryl; n is an integer of from 4 to 40 and m is an integer of from 1 to 4; B is hydrogen or A; and M is a proton or a sodium, potassium or triethanolammonium cation; and (ii) from 0.5 to 10% by weight of at least one nonionic polyglycol ether surfactant, said surfactant including a compound of the formula: R.sub.8 O--(C.sub.2 H.sub.4 O).sub.p --C.sub.2 H.sub.4 --OH wherein p is an integer from 2 to 44, and R 8 is alkyl of from 12 to 18 carbon atoms, alkanoyl of 12 to 22 carbon atoms, alkadienoyl of 12 to 22 carbon atoms, alkatrienoyl of 12 to 22 atoms, phenyl substituted with cycloalkyl of 5 to 8 carbon atoms or phenyl substituted with from one to three alkyl groups of from 3 to 10 carbon atoms, and (c) water.
Claim 2
Dependent Claim 343 words
A flowable herbicidal composition having at least one solid disperse phase and a continuous aqueous phase comprising (a) combination of (i) from 10 to 50% by weight of at least chlorotriazine of the formula: ##STR5## wherein R 1 is alkyl of 1 to 4 carbon atoms, R 2 is hydrogen or alkyl of 1 to 4 carbon atoms, and R 3 is cycloalkyl of 3 or 4 carbon atoms, alkyl of 1 to 4 carbon atoms, or alkyl of 1 to 4 carbon atoms substituted with methoxy or cyano; and (ii) from 10 to 50% by weight of at least one chloroacetanilide of the formula ##STR6## wherein each of R 4 and R 5 , independently of the other, is methyl or ethyl and R 6 is alkynyl of 3 or 4 carbon atoms, alkyl of 1 to 3 carbon atoms, or alkyl of 1 to 3 carbon atoms substituted with alkoxy of 1 to 4 carbon atoms, ethoxy carbonyl, or pyrazolyl; (b) a surfactant system consisting essentially of (i) from 1 to 10% by weight of at least one anionic surfactant of the formula: ##STR7## wherein A is ##STR8## in which R 7 is hydrogen, alkyl of 3 to 10 carbon atoms or styryl; n is an integer of from 4 to 40 and m is an integer of from 1 to 4; B is hydrogen or A; and M is a proton or a sodium, potassium or triethanolammonium cation; and (ii) from 0.5 to 10% by weight of at least one nonionic polyglycol ether surfactant, said surfactant including a compound of the formula: R.sub.8 O--(C.sub.2 H.sub.4 O).sub.p --C.sub.2 H.sub.4 --OH wherein p is an integer from 2 to 44, and R 8 is alkyl of from 12 to 18 carbon atoms, alkanoyl of 12 to 22 carbon atoms, alkadienoyl of 12 to 22 carbon atoms, alkatrienoyl of 12 to 22 atoms, phenyl substituted with cycloalkyl of 5 to 8 carbon atoms or phenyl substituted with from one to three alkyl groups of from 3 to 10 carbon atoms, and (c) water.
Claim 3
Dependent Claim 21 words
