Abstract

Synergistic insecticidal combinations of esters of certain cyclopropanecarboxylic acids, e.g. pyrethrins, allethrin, and related compounds, with mono(alkyl and alkenyl) mono-.omega.-alkynyl aryl- and aralkylphosphonates are described. The preparation and properties of representative members of this new class of synergistic phosphonates are described, and test results of their synergistic combinations with representative cyclopropanecarboxylates are reported.
