Claims9
Method for the protection of maize from damage by herbicidally active acetanilides of the formula ##STR21## in which R.sup.4 is pyrazol-1-yl or pyrazol-1-yl substituted by one or more radicals selected from fluorine, chlorine, bromine and alkyl with one to four carbon atoms,
- X and Y are identical or different and represent alkyl with one to four carbon atoms,
- Z represents halogen and
- n represents 0, 1 or 2,
- which method comprises applying to the maize plants or to their habitat, an antidotally effective amount of an N-acyl-piperidone compound of the formula ##STR22## wherein R is methyl or chloro.
Herbicidal composition comprising an herbicidally active compound selected from acetanilide herbicides of the formula ##STR23## in which R.sup.4 is pyrazol-1-yl or pyrazol-1-yl substituted by one or more radicals selected from fluorine, chlorine, bromine and alkyl with one to four carbon atoms,
- X and Y are identical or different and represent alkyl, with one to four carbon atoms,
- Z represents halogen and
- n represents 0, 1 or 2, and, as an antidote, an effective amount of an N-acyl-piperidone compound of the formula ##STR24## wherein R is methyl or chloro.
