Aluminium phosfidendi fumigant ndi tizilombo ntchito kwambiri kunyumba ndi kunja. Cholinga chake chachikulu ndikupewa ndikuwongolera tizilombo towononga zinthu zomwe zasungidwa monga tirigu ndi mankhwala aku China. Chigawochi chimatenga mpweya wamadzi mumpweya ndipo pang'onopang'ono amawola kuti atulutse mpweya wa phosphine (PH3), womwe ungagwiritsidwe ntchito ngati mankhwala ophera tizilombo. Phosphine ndi mpweya wopanda mtundu, wapoizoni kwambiri wokhala ndi fungo la acetylene. Ili ndi mphamvu yokoka ya 1.183, yomwe ndi yolemera pang'ono kuposa mpweya koma yopepuka kuposa mipweya ina yofukiza. Gasi ali ndi permeability kwambiri komanso diffusivity, kupangitsa kukhala yabwino komanso yothandiza polimbana ndi tizilombo.
Pali njira zenizeni zothirira dothi ndi aluminiyamu phosphide kuti muchepetse mizu ya masamba a nematodes. Pafupifupi 22.5-75 kg ya 56% aluminiyamu phosphide piritsi mankhwala ntchito pa hekitala. Konzani nthaka pothira kapena kukumba dzenje lakuya masentimita 30. Mankhwala ophera tizilombo amawapopera pamanja pamalo okonzedwawo kenako n’kutidwa ndi dothi. Kapena gwiritsani ntchito makina kuti mugwiritse ntchito mankhwala ophera tizilombo m'nthaka mozama masentimita 30, ndikuphimba ndi filimu yapulasitiki. Musanafese ndi kubzala mbewu kapena masamba, fumigate nthaka kwa masiku 5 mpaka 7.
Njira yofusirayi pogwiritsa ntchito aluminium phosphide flakes ndiyoyenera makamaka ku greenhouse masamba monga tomato, nkhaka, zukini, biringanya, tsabola, nyemba za impso, ndi njere. Mitundu ya ndiwo zamasamba imakula bwino ikabzalidwa m'nthaka yothiridwa ndi aluminium phosphide flakes. Kuphatikiza apo, njirayi ndi yothandizanso pochiza nthaka yotseguka komanso kuwongolera matenda a mizu ya nematode ya mbewu zofunika pazachuma monga ginger, masamba, mtedza ndi fodya.
Kufukiza pogwiritsa ntchito aluminium phosphide ndi chida chofunikira pazaulimi. Imatha kulowa m'njira yopumira kapena nembanemba ya tizirombo, kuonetsetsa kuti poyizoni yachangu komanso yakupha ndikuchotsa bwino tizilombo towononga izi. Pogwiritsira ntchito mlingo woyenera ndi kutsatira njira zoyenera zofukizira, alimi ndi alimi angateteze zokolola zawo zosungidwa pamodzi ndi mbewu zawo ku zotsatira zowononga za tizirombo.
Kuonjezera apo, kugwiritsa ntchito ma aluminium phosphide flakes mu ndondomeko ya fumigation kumapereka njira yabwino kwambiri poyerekeza ndi njira zina. Mphamvu zake zolowera ndi kufalikira zimalola kuti zigawike bwino m'nthaka, kuloza tizirombo komanso kupewa kufalikira kwa matenda a root-knot nematode. Kuonjezera apo, njira yosavuta yopopera mankhwala kapena kuyika mapiritsi m'nthaka imapangitsa kuti alimi akhale osavuta komanso osavuta kupeza.
Ponseponse, ma flakes a aluminium phosphide atsimikizira kukhala yankho lofunikira pakufukiza kwaulimi komanso kuthana ndi tizirombo. Kuchita bwino kwawo, kumasuka komanso kugwiritsa ntchito mitundu yosiyanasiyana kumawapangitsa kukhala chida chofunikira poteteza zokolola zosungidwa ndi mbewu ku zotsatira zoyipa za tizirombo. Pogwiritsa ntchito moyenera komanso kutsatira malangizo omwe aperekedwa, alimi amatha kuteteza zokolola zawo ndikuonetsetsa kuti zokolola zawo zikuyenda bwino.
