The Synthetic Pyrethroids PBO mu Stock

 Mafotokozedwe Akatundu

 Piperonyl butoxide yogwira mtima kwambiri (PBO) ndi amodzi mwama synergists odziwika bwino kuti awonjezere mphamvu ya Mankhwala ophera tizilombo.Sikuti mwachionekere kuonjezera mankhwala zotsatira kuposa kakhumi, komanso kuonjezera zotsatira zake nthawi.

 PBO imaphatikizira zapakatikati ndipo imagwiritsidwa ntchito kwambiri paulimi, thanzi labanja komanso chitetezo chosungira.Ndilo mphamvu yokhayo yovomerezekaMankhwala ophera tizilomboamagwiritsidwa ntchito paukhondo wazakudya (kupanga chakudya) ndi UN Hygiene Organisation.Ndi chowonjezera chapadera cha thanki chomwe chimabwezeretsa ntchito motsutsana ndi tizilombo tolimbana ndi tizilombo.Zimagwira ntchito poletsa ma enzyme omwe amapezeka mwachilengedwe omwe angawononge molekyulu ya tizilombo.PBO imaphwanya chitetezo cha tizilombo ndipo kugwirizana kwake kumapangitsa kuti tizilombo toyambitsa matenda tikhale amphamvu komanso ogwira mtima.

 Kachitidwe

 Piperonyl butoxide imatha kupititsa patsogolo ntchito yowononga tizilombo ya pyrethroids ndi tizilombo tosiyanasiyana monga pyrethroids, rotenone, ndi carbamates.Ilinso ndi synergistic zotsatira pa fenitrothion, dichlorvos, chlordane, trichloromethane, atrazine, ndipo akhoza kusintha bata akupanga pyrethroid.Mukamagwiritsa ntchito ntchentche zapakhomo ngati chinthu chowongolera, mphamvu ya synergistic ya mankhwalawa pa fenpropathrin ndi yayikulu kuposa ya octachloropropyl ether;Koma ponena za kugwetsa kwa ntchentche zapakhomo, cypermethrin silingagwirizane.Mukagwiritsidwa ntchito muzofukiza zothamangitsira udzudzu, palibe synergistic kwenikweni pa permetrin, ndipo ngakhale mphamvuyo imachepetsedwa.
