Documented Uses

• Used as a selective miticide for the control of a variety of mite pests on ornamental plants and fruit trees in greenhouses, nurseries, and landscapes; [HSDB]
• Acaricide/miticide, insecticide.
• Bifenazate can be prepared by Lewis acid-catalyzed electrophilic aromatic substitution of 4-methoxybiphenyl with diisopropyl azodicarboxylate yielding hydrazine dicarboxylate, which is then transformed into the compound desired by a decarboxylation reaction.
