100% Yoyambirira ya Zanyama Zowononga Tizilombo Yopha Tizilombo Piperonyl butoxide

Mafotokozedwe Akatundu

Piperonyl butoxide (PBO) yogwira ntchito bwino kwambiri ndi imodzi mwa njira zabwino kwambiri zowonjezerera mphamvu ya mankhwala ophera tizilombo. Sikuti imangowonjezera mphamvu ya mankhwala ophera tizilombo nthawi zoposa khumi, komanso imatha kukulitsa nthawi yake yogwiritsira ntchito mankhwala.

PBO ndi mankhwala opangidwa ndi zinthu zosiyanasiyana ndipo amagwiritsidwa ntchito kwambiri pa ulimi, thanzi la mabanja komanso kuteteza kusungidwa kwa zinthu. Ndi mankhwala okhawo ovomerezeka ophera tizilombo omwe amagwiritsidwa ntchito pa ukhondo wa chakudya (kupanga chakudya) ndi bungwe la UN Hygiene Organization. Ndi chowonjezera chapadera cha thanki chomwe chimabwezeretsa mphamvu yolimbana ndi mitundu yolimbana ndi tizilombo. Chimagwira ntchito poletsa ma enzyme achilengedwe omwe akanawononga molekyulu ya tizilombo. PBO imaphwanya chitetezo cha tizilombo ndipo ntchito yake yogwirizana imapangitsa tizilombo kukhala amphamvu komanso ogwira ntchito.

Njira Yochitira Zinthu

Piperonyl butoxide imatha kuwonjezera mphamvu yopha tizilombo ya pyrethroids ndi mankhwala osiyanasiyana ophera tizilombo monga pyrethroids, rotenone, ndi carbamates. Imakhalanso ndi mphamvu yogwirizana pa fenitrothion, dichlorvos, chlordane, trichloromethane, atrazine, ndipo imatha kukonza kukhazikika kwa zotulutsa za pyrethroid. Pogwiritsa ntchito ntchentche zapakhomo ngati chinthu chowongolera, mphamvu yogwirizana ya mankhwalawa pa fenpropathrin ndi yayikulu kuposa ya octachloropropyl ether; Koma pankhani ya mphamvu yogwetsa ntchentche zapakhomo, cypermethrin singagwiritsidwe ntchito. Ikagwiritsidwa ntchito mu zofukiza zochotsa udzudzu, palibe mphamvu yogwirizana pa permethrin, ndipo ngakhale mphamvu yake imachepa.
