Insecticidal compositions and methods of combatting insects using 3- phenoxybenzyl 2,2-dimethyl-3-(2,2-dichlorovinyl)- cyclopropanecarboxylate insecticide with a synergistic compound of mono (alkyl and alkenyl)mono omega-alkynyl arylphosphonates

摘要

Synergistic insecticidal combinations of esters of certain cyclopropanecarboxylic acids, e.g. pyrethrins, allethrin, and related compounds, with mono(alkyl and alkenyl) mono-&ohgr;-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.
