Aluminiyamu phosphide 56% TAB |Fumigant yowononga tizirombo mu nyumba yosungiramo katundu
Mawu Oyamba
Aluminium phosphide imathandiza kwambiri kupha tizirombo chifukwa chotulutsa mpweya wapoizoni wotchedwa phosphine (PH3) ukakumana ndi chinyezi, makamaka mpweya wamadzi kapena chinyezi chachilengedwe.
Njira yamachitidwe a mpweya wa phosphine makamaka kudzera pakutha kwake kusokoneza kupuma kwa ma cell mu tizirombo, zomwe zimatsogolera ku imfa yawo.
Kachitidwe
Nawa kufotokozera mwatsatanetsatane momwe aluminium phosphide imagwirira ntchito:
- Kutulutsidwa kwa Mafuta a Phosphine:
- Aluminium phosphide imapezeka ngati ma pellets kapena mapiritsi.
- Ikakumana ndi chinyezi, monga chinyezi chamumlengalenga kapena chinyezi pamalo omwe mukufuna, aluminiyamu phosfide imakhudzidwa ndikutulutsa mpweya wa phosphine (PH3).
- Zomwe zimachitika motere: Aluminium phosphide (AlP) + 3H2O → Al(OH)3 + PH3.
- Kachitidwe:
- Mpweya wa Phosphine (PH3) ndi wakupha kwambiri ku tizirombo, kuphatikiza tizilombo, makoswe, ndi tizirombo tina tosungidwa.
- Tizilombo tikakumana ndi mpweya wa phosphine, timawutenga kudzera m'mapu awo.
- Mpweya wa phosphine umasokoneza kupuma kwa ma cell mu tizirombo poletsa ntchito ya michere yomwe imayambitsa kupanga mphamvu (makamaka, imasokoneza mayendedwe a ma elekitironi a mitochondrial).
- Zotsatira zake, tizirombo timalephera kupanga adenosine triphosphate (ATP), yomwe ndi yofunika kuti ikhale ndi mphamvu zama cell, zomwe zimapangitsa kuti kagayidwe kake kagayidwe kachakudya zisagwire bwino ntchito ndipo pamapeto pake kufa.
- Broad-Spectrum Activity:
- Mpweya wa phosphine umagwira ntchito mosiyanasiyana, kutanthauza kuti umatha kuthana ndi tizirombo tosiyanasiyana, kuphatikiza tizilombo, nematode, makoswe, ndi tizirombo tina tomwe timapezeka mumbewu zosungidwa, zinthu, ndi kapangidwe kake.
- Ndiwothandiza polimbana ndi tizirombo tosiyanasiyana, kuphatikiza mazira, mphutsi, pupae, ndi akuluakulu.
- Mpweya wa phosphine umatha kulowa kudzera muzinthu zopangira porous, kufika kumalo obisika kapena ovuta kufika kumene tizilombo tingakhalepo.
- Zachilengedwe:
- Kutulutsidwa kwa mpweya wa phosphine kuchokera ku aluminiyamu phosphide kumakhudzidwa ndi zinthu zachilengedwe monga kutentha, chinyezi, ndi pH.
- Kutentha kwambiri komanso chinyezi kumathandizira kutulutsa mpweya wa phosphine, kukulitsa mphamvu yake pothana ndi tizirombo.
- Komabe, chinyontho chambiri chingathenso kuchepetsa mphamvu ya mpweya wa phosphine, chifukwa ukhoza kuchitapo kanthu mwamsanga ndikukhala wosagwira ntchito.
