Bifenazate is a carbazate acaricide that provides 100% control of mites when used at a concentration of 25 ppm.1 It acts as a positive allosteric modulator of GABA receptors containing the resistance to dieldrin (Rdl) subunit homolog TuGABAR in T. urticae (spider mites), shifting the GABA-induced response from an EC50 value of 24.8 to 4.83 ?M when used at a concentration of 30 ?M.2 Formulations containing bifenazate have been used for the control of mites and for pesticide detection.
