    • or an ester or salt thereof, and
  • (B) a herbicide of the formula (B1)

• • • in which X represents N or CH and R represents CO₂H or a herbicidally active derivative thereof,
      and the corn crops are tolerant, if appropriate in the presence of safeners, to the herbicides (A) and (B) present in the combination.
