Insecticidal and/or Herbicidal Composition Having Improved Activity Based on Spiroheterocyclically Substituted Tetramic Acid Derivatives

摘要

The present invention relates to boosting the action of crop protection compositions comprising in particular spiroheterocyclically substituted tetramic acid derivatives of the formula (I) by addition of ammonium or phosphonium salts and optionally penetrants, to the corresponding compositions, to processes for their preparation and to their use in crop protection as insecticides and/or acaricides and/or for preventing unwanted vegetation.
