Aluminium phosphideifumigant uye mushonga wezvipembenene unoshandiswa zvakanyanya kumba nekune dzimwe nyika. Chinangwa chayo chikuru ndechekudzivirira nekudzora zvipembenene zvinokanganisa zvigadzirwa zvakachengetwa zvakaita sezviyo nemishonga yeChinese. Mushonga uyu unotora mhute yemvura mumhepo uye zvishoma nezvishoma inoora kuburitsa phosphine (PH3) gasi, inogona kushandiswa semushonga wezvipembenene unoshanda. Phosphine igasi risina ruvara, rine muchetura zvikuru rine kunhuhwirira kwakasiyana kweacetylene. Iine giravhiti chaiyo ye1.183, inorema zvishoma pane mweya asi yakareruka kupfuura mamwe magasi anopfungaira. Iyo gasi ine yakanakisa permeability uye diffusivity, zvichiita kuti ive iri nyore uye inoshanda kudzora tupukanana sarudzo.

Pane nzira dzakananga dzekupfuudza ivhu nealuminium phosphide kudzora muriwo mudzi-knot nematodes. Inenge 22.5-75 kg ye56% aluminum phosphide piritsi remushonga wemishonga inoshandiswa pahekita. Gadzirira ivhu nekuchera kana kuchera gomba rakadzika masendimita makumi matatu. Mishonga inopfapfaidzwa nemaoko panzvimbo idzi dzakagadzirirwa yobva yafukidzwa nevhu. Kana kushandisa michina kuisa zvakananga mishonga yezvipembenene muvhu kusvika pakadzika 30 cm, uye wozovhara nefirimu repurasitiki. Usati wadyara nekudyara mbesa kana miriwo, fumigate ivhu kwemazuva mashanu kusvika manomwe.

Iyi nzira yefumigation uchishandisa aluminium phosphide flakes inonyanya kukodzera miriwo yegreenhouse yakaita sematomatisi, magaka, zucchini, eggplants, mhiripiri, bhinzi dzeitsvo, uye cowpeas. Mhando dzemuriwo idzi dzinobudirira kana dzakadyarwa muvhu rakabatwa nealuminium phosphide flakes. Pamusoro pezvo, nzira iyi inoshandawo mukurapa ivhu remumunda wakavhurika nekudzora zvirwere zvemidzi-knot nematode zvezvirimwa zvakakosha zveupfumi zvakaita seginger, muriwo, nzungu nefodya.

Fumigation uchishandisa aluminium phosphide chinhu chakakosha mukuita zvekurima. Inokwanisa kupinda mukati mekufema system kana membrane yemuviri wezvipembenene, kuve nechokwadi chekukurumidza uye chinouraya chepfu uye nekupedza kubvisa zvipembenene izvi zvinokuvadza. Kuburikidza nekushandisa muyero wakakodzera uye nekutevedzera nzira dzekufutisa, varimi nevarimi vanogona kuchengetedza zvirimwa zvavo zvakachengetwa pamwe nembeu dzavo kubva mukukuvadza kwezvipembenene.

Mukuwedzera, kushandiswa kwealuminium phosphide flakes mukugadzirisa fumigation kunopa nzira iri nyore kana ichienzaniswa nedzimwe nzira. Kupinda kwayo kwakasimba nekupararira kwayo kunobvumira kugovaniswa kunoshanda muvhu rose, kunyatsonangana netwupukanana uye kudzivirira kupararira kwechirwere chemidzi-knot nematode. Pamusoro pezvo, nzira iri nyore yekupfapfaidza kana kuisa mapiritsi muvhu inoita kuti zvive nyore uye zvinogoneka kune varimi.

Pakazere, aluminium phosphide flakes yakaratidza kuve mhinduro yakakosha yekurima fumigation uye kudzora tumbuyu. Kubudirira kwavo, kureruka uye kuwanda kwekushandisa kunoita kuti zvive chinhu chakakosha mukudzivirira zvakachengetwa zvigadzirwa uye zvirimwa kubva kune zvinokuvadza zvezvipembenene. Nekushandisa nemazvo uye kutevedzera mirairo inokurudzirwa, varimi vanokwanisa kuchengetedza goho nekubudirira uye kuona hutano nekukura kwegoho ravo.
