I-aluminium phosphidesisibulali zinambuzane esisetyenziswa kakhulu ekhaya nakumazwe angaphandle. Injongo yalo ephambili kukuthintela ngokufanelekileyo kunye nokulawula izinambuzane ezitshabalalisa iimveliso ezigciniweyo ezifana nengqolowa kunye nezixhobo zonyango zaseTshayina. Le khompawundi ifunxa umphunga wamanzi emoyeni kwaye ibole ngokuthe ngcembe ukukhulula i-phosphine (PH3) igesi, enokusetyenziswa njengesibulali-zinambuzane esisebenzayo. Iphosphine yirhasi engenambala, enetyhefu kakhulu enevumba leacetylene elahlukileyo. Inobunzima obuthile obuyi-1.183, obubunzima kancinci kunomoya kodwa bukhaphukhaphu kunezinye iigesi ezifuthayo. Irhasi inobuchwephesha obugqwesileyo kunye ne-diffusivity, iyenza ibe lukhetho olufanelekileyo nolusebenzayo lokulawula izinambuzane.

Kukho iindlela ezikhethekileyo zokufunxa umhlaba nge-aluminiyam phosphide ukulawula imifuno yengcambu-nematodes. Malunga ne-22.5-75 kg ye-56% ye-aluminiyam ye-aluminiyam ye-phosphide yokwakheka kwe-pesticide isetyenziswe kwihektare nganye. Lungisa umhlaba ngokugalela okanye ngokugrumba umngxuma obunzulu obungama-30 cm. Amayeza okubulala izitshabalalisi atshizwa ngesandla kwezi ndawo zilungisiweyo aze agqunywe ngomhlaba. Okanye sebenzisa oomatshini ukufaka amayeza okubulala izitshabalalisi ngokuthe ngqo emhlabeni ukuya kubunzulu obungama-30 cm, uze ugqume ngefilimu yeplastiki. Ngaphambi kokuhlwayela kunye nokutshintshela izityalo okanye imifuno, fumigate umhlaba iintsuku ezi-5 ukuya kwezi-7.

Le ndlela yokutshisa usebenzisa i-aluminiyam phosphide flakes ifaneleke ngokukodwa kwimifuno yegreenhouse efana neetumato, iikomkomere, izucchini, ii-eggplants, iipepile, iimbotyi zezintso, kunye ne-cowpeas. Ezi ndidi zemifuno zikhula kakuhle xa zityalwe kumhlaba ophathwe nge aluminium phosphide flakes. Ukongeza, indlela iyasebenza ekunyangeni umhlaba ovulekileyo kunye nokulawula izifo ze-root-knot nematode zezityalo ezibalulekileyo kwezoqoqosho ezifana nejinja, imifuno, amandongomane kunye necuba.

Ukutshisa usebenzisa i-aluminium phosfide sisixhobo esibalulekileyo kwimisebenzi yezolimo. Iyakwazi ukungena kwinkqubo yokuphefumula okanye i-membrane yomzimba wezinambuzane, iqinisekisa ityhefu ekhawulezayo kunye neyokubulala kunye nokuphelisa ngokufanelekileyo ezi zinambuzane eziyingozi. Ngokusebenzisa idosi efanelekileyo kunye nokulandela iindlela ezifanelekileyo zokutshisa, abalimi kunye nabalimi banokukhusela imveliso yabo egciniweyo kunye nezityalo zabo kwimiphumo eyingozi yezinambuzane.

Ukongezelela, ukusetyenziswa kwe-aluminium phosphide flakes kwinkqubo yokufunxa inika indlela efanelekileyo ngakumbi xa kuthelekiswa nezinye iindlela. Amandla ayo okungena kunye nokusabalalisa iimpawu avumela ukusasazwa okusebenzayo kuwo wonke umhlaba, ukujolisa ngokufanelekileyo izinambuzane kunye nokuthintela ukusasazeka kwesifo se-root-knot nematode. Ukongeza, inkqubo elula yokutshiza okanye ukugalela iipilisi emhlabeni yenza kube lula kwaye kufikeleleke kumafama.

Ngokubanzi, iiflake ze-aluminium phosphide zibonakalise ukuba sisisombululo esibalulekileyo sokutshisa kwezolimo kunye nolawulo lwezinambuzane. Ukusebenza kwabo, ukulungeleka kunye noluhlu olubanzi lwezicelo zenza ukuba zibe sisixhobo esibalulekileyo ekukhuseleni imveliso egciniweyo kunye nezityalo kwimiphumo emibi yezinambuzane. Ngokusetyenziswa ngokufanelekileyo kunye nokuthobela izikhokelo ezicetyiswayo, abalimi banokukhusela ngempumelelo izivuno kwaye baqinisekise impilo kunye nokukhula kwemveliso yabo.
