Lub sijhawm tiv thaiv yog kwv yees li 14 hnub, nyob ntawm seb cov kab tsuag thiab huab cua zoo li cas. Beta-cypermethrin muaj tshuaj lom rau muv, ntses, kab ntsig, thiab cov tsiaj hauv dej - tsis txhob siv thaum lub sijhawm paj, ze cov chaw ua liaj ua teb, thaj chaw cog qoob loo, lossis cov dej.
Lub sijhawm ua ntej sau qoob loo (PHI) sib txawv raws li qoob loo: 7 hnub rau zaub qhwv (tsis pub tshaj 3 zaug/lub caij), 3 hnub rau taum pauv (tsis pub tshaj 1 zaug/lub caij), 21 hnub rau txiv apples thiab txiv pears (tsis pub tshaj 2 zaug/lub caij), 40 hnub rau beet qab zib (tsis pub tshaj 2 zaug/lub caij), 60 hnub rau paj noob hlis.
Cov Lus Ceeb Toom:
Kev Lom Zem Rau Cov Kab Mob Uas Tsis Yog Lub Hom Phiaj: Beta-cypermethrin muaj tshuaj lom heev rau cov muv zib ntab, ntses, kab laug sab, thiab feem ntau cov kab mob hauv dej. Tsis txhob siv thaum lub sijhawm paj, ze ntawm cov chaw ua liaj ua teb, thaj chaw cog qoob loo, lossis pas dej ntses.

Tsis Txhob Sib Tov Nrog Cov Tshuaj Alkaline: Cov khoom no tsis ruaj khov nyob rau hauv cov xwm txheej alkaline thiab yuav lwj sai sai. Tsis txhob sib tov nrog cov tshuaj tua kab alkaline xws li Bordeaux sib tov lossis cov kua qaub sulfur. Siv cov dej nruab nrab lossis me ntsis acidic rau kev dilution.
Kev puas tsuaj ib puag ncig: Beta-cypermethrin tsis nyob ntev hauv av (DT₅₀ kwv yees li 27 hnub) thiab lwj sai sai rau ntawm cov nroj tsuag (RL₅₀ kwv yees li 4.9 hnub). Txawm li cas los xij, nws muaj tshuaj lom heev rau cov tsiaj hauv dej nrog cov teebmeem ntev.
