Bifenazate ndi mankhwala acaricide omwe amagwira ntchito motsutsana ndi kangaude, zofiira ndi udzu, kuphatikizapo mazira.Zimakhala ndi kugwetsa mwachangu (nthawi zambiri zosakwana masiku atatu) komanso zotsalira patsamba zomwe zimatha mpaka milungu inayi.Zochita za mankhwalawa sizidalira kutentha - kulamulira sikuchepetsedwa pa kutentha kochepa.Sichiletsa dzimbiri, fulati- kapena nthata zazikulu.
Kafukufuku mpaka pano akuwonetsa kuti bifenazate imachita ngati wotsutsa wa GABA (gamma-aminobutyric acid) mu zotumphukira zamanjenje dongosolo pa neuromuscular synapse mu tizilombo.GABA ndi amino acid yomwe ilipo mu dongosolo lamanjenje la tizilombo.Bifenazate imatchinga njira za GABA-activated chloride, zomwe zimapangitsa kuti pakhale chisangalalo chambiri cha zotumphukira zamanjenje za tizirombo.Izi zikunenedwa kukhala zapadera pakati pa ma acaricides, zomwe zikuwonetsa kuti mankhwalawa atha kukhala ndi gawo lofunikira kwambiri m'tsogolo polimbana ndi mite resistance.
Ndi acaricide yosankha kwambiri yomwe imayang'anira akangaude, Tetranychus urticae.Bifenazate ndi chitsanzo choyamba cha carbazate acaricide.Ili ndi kusungunuka kwamadzi pang'ono, kosasunthika ndipo sikungayembekezere kutsika pansi pamadzi.Bifenate sichiyembekezekanso kuti ipitirire m'nthaka kapena madzi.Ndiwowopsa kwambiri kwa nyama zoyamwitsa komanso khungu lodziwika bwino, maso ndi kupuma.Ndiwowopsa kwambiri kwa zamoyo zambiri zam'madzi, njuchi ndi nyongolotsi.
Kafukufuku wa pa yunivesite ya Florida kumapeto kwa zaka za m'ma 1990 adawonetsa zotheka kukana kwa abamectin mu nthata za mawanga awiri mu sitiroberi;bifenazate angapereke chithandizo china.
M'mayesero am'munda, palibe phytotoxicity yomwe idanenedwa, ngakhale pamitengo yokulirapo kuposa yomwe ikulimbikitsidwa.Bifenazate ndiyowopsa m'maso mwapang'onopang'ono ndipo imatha kuyambitsa matupi akhungu.Bifenazate imagawidwa kukhala yopanda poizoni kwa nyama zazing'ono zoyamwitsa pakamwa pakamwa.Ndi poizoni ku chilengedwe cha m'madzi ndipo ndi poizoni kwambiri ku zamoyo zam'madzi zomwe zimakhala ndi zotsatira zokhalitsa.
