Abstract
Abstract Herbicides containing a mixture of a cyclohexane-1,3-dione derivative of the formula ##STR1## where R 1 , R 2 , R 3 , Y and n have the meanings given in the description, and a 3,6-dichloro-2-picolinic acid derivative of the formula ##STR2## where R has the meaning given in the description. These herbicide mixtures display a synergistic action, especially on grassy plants.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
A herbicidal agent consisting essentially of a mixture of 2-(1-ethoxyaminobutylidene)-5-(2-ethylthiopropyl)-cyclohexane-1,3-diione (I) or a metal salt, an unsubstituted or substituted ammonium salt, or a hydrate of said compound and a 3,6-dichloro-2-picolinic acid derivative of the formula II ##STR5## where R is hydrogen or straight-chain or branched alkyl of 1 to 4 carbon atoms, or a metal salt or unsubstituted or substituted ammonium salt of the acid, wherein the ratio of compound (I) to compound (II) is from 1:0.06 to 1:5.
Claim 2
Dependent Claim
79 words
A herbicidal agent consisting essentially of a mixture of 2-(1-ethoxyaminobutylidene)-5-(2-ethylthiopropyl)-cyclohexane-1,3-diione (I) or a metal salt, an unsubstituted or substituted ammonium salt, or a hydrate of said compound and a 3,6-dichloro-2-picolinic acid derivative of the formula II ##STR5## where R is hydrogen or straight-chain or branched alkyl of 1 to 4 carbon atoms, or a metal salt or unsubstituted or substituted ammonium salt of the acid, wherein the ratio of compound (I) to compound (II) is from 1:0.06 to 1:5.
Claim 3
Dependent Claim
56 words
A herbicidal agent consisting essentially of a mixture of 2-(1-ethoxyaminobutylidene)-5-(2-ethylthiopropyl)-cyclohexane-1,3-dione or a metal salt, an unsubstituted or substituted ammonium salt or a hydrate thereof and 3,6-dichloro-2-picolinic acid or a metal salt or an unsubstituted or substituted ammonium salt thereof, wherein the ratio of the cyclohexane-1,3-dione derivative to the picolinic acid derivative is from 1:5 to 1:0.025.
Claim 4
Dependent Claim
56 words
A herbicidal agent consisting essentially of a mixture of 2-(1-ethoxyaminobutylidene)-5-(2-ethylthiopropyl)-cyclohexane-1,3-dione or a metal salt, an unsubstituted or substituted ammonium salt or a hydrate thereof and 3,6-dichloro-2-picolinic acid or a metal salt or an unsubstituted or substituted ammonium salt thereof, wherein the ratio of the cyclohexane-1,3-dione derivative to the picolinic acid derivative is from 1:5 to 1:0.025.
