- 3. A process for the selective control of unwanted plants, wherein the acetanilide of the formula II and the dichloroacetamide of the formula I as claimed in claim 1 are applied, simultaneously or one after the other in any sequence, before, during or after sowing of the crop plants, or before or during emergence of the crop plants.
- 4. A process for the selective control of unwanted plants with acetanilides of the formula II, wherein the crop plant seed is treated with a dichloroacetamide of the formula I as claimed in claim 1.
- 5. A process as set forth in claim 3 wherein the crop plant is a cereal.
- 6. A process as set forth in claim 4 wherein the crop plant is a cereal.
- 7. A herbicidal agent as set forth in claim 1, wherein the sum of p+q in the compound of formula I is 1 or 2.
- 8. A herbicidal agent as defined in claim 1, wherein the acetanilide of the formula II is selected from the group consisting of 2-chloro-2',6'-dimethyl-N-(pyrazol-1-yl-methyl)-acetanilide, 2-chloro-2'-methyl-6'-ethyl-N-(pyrazol-1-yl-methyl)-acetanilide, 2-chloro-2',6'-dimethyl-N-(4-methyl-pyrazol-1-yl-methyl)-acetanilide, 2-chloro-2'-methyl-6'-ethyl-N-(4-methoxy-pyrazol-1-yl-methyl)-acetanilide, 2-chloro-2',6'-dimethyl-N-(3,5-dimethylpyrazol-1-yl-methyl)-acetanilide, 2-chloro-2'-methyl-6'-ethyl-N-(3-methylpyrazol-1-yl-methyl)-acetanilide, 2-chloro-2',6'-dimethyl-N-(1,2,4-triazol-1-yl-methyl)-acetanilide and 2-chloro-2',3',6'-trimethyl-N-(pyrazol-1-yl-methyl)-acetanilide.
- 9. A herbicidal agent as defined in claim 1, wherein A an is azole radical and the antagonist is selected from the group consisting of 5-dichloroacetyl-6-methyl-9-oxo-1,5-diazabicyclo[4.3.0]-nonane and 5-dichloroacetyl-3,3,6-trimethyl-9-oxo-1,5-diazabicyclo[4.3.0]nonane.
- 10. A herbicidal agent as defined in claim 1, wherein the acetanilide of the formula II is 2-chloro-2',6'-dimethyl-N-(pyrazol-1-yl-methyl)-acetanilide and wherein the antagonist of formula I is selected from the group consisting of 5-dichloroacetyl-6-methyl-9-oxo-1,5-diazabicyclo[4.3.0]-nonane and 5-dichloroacetyl-3,3,6-trimethyl-9-oxo-1,5-diazabicyclo[4,3.0]nonane.
