Ucwaningo lwaseCanada lubonisa ukuthi i-diatomite inezigaba ezimbili ezinkulu: amanzi olwandle namanzi ahlanzekile. I-diatomite yamanzi olwandle iphumelela kakhulu kune-diatomite yamanzi ahlanzekile ekulawuleni izinambuzane ezigciniwe zokusanhlamvu. Isibonelo, umthamo we-565ppm wanikezwa ukolweni ophathwe ngamanzi olwandle i-diatomite 209, lapho izindlovu zelayisi zavezwa khona izinsuku ezinhlanu, okubangele izinga lokufa elingamaphesenti angu-90. Ngamanzi ahlanzekile e-diatomite, ngaphansi kwezimo ezifanayo, izinga lokufa kwezindlovu zerayisi lifika kumaphesenti angama-90 omthamo we-1,013 PPM.

Ngenxa yokusetshenziswa kwesikhathi eside nokuningi kwe-phosphine (PH_3) njengesifuthefuthe, lesi sitshalo siye samelana naso kanzima futhi asikwazi ukubulawa ngezindlela ezijwayelekile zokufuthwa kwe-phosphine. E-UK, ama-insecticide e-organophosphorus kuphela atholakalayo njengamanje ukuze kulawulwe izibungu zokudla ezigciniwe, kodwa lezi zibulala-zinambuzane zamakhemikhali azisebenzi ekulweni nezibungu ze-acaroid emadepho okusanhlamvu namadepho embewu kawoyela. Ngaphansi kwesimo sezinga lokushisa elingu-15℃ kanye nomswakama ohlobene no-75%, lapho umthamo we-diatomite kokusanhlamvu wawungu-0.5 ~ 5.0 g/kg, izimbuzane ze-acaroid zingabulawa ngokuphelele. Indlela ye-acaricidal ye-diatomite powder iyafana neyezinambuzane, ngoba kukhona ungqimba lwe-wax oluncane kakhulu (i-cap horn layer) kungqimba lwe-epidermal odongeni lomzimba lwezibungu ze-acaroid.

Ukusetshenziswa kwei-diatomiteukulawula izinambuzane ezisanhlamvu ezigciniwe zathuthukiswa eminyakeni eyi-10 edlule. Ucwaningo olunzulu lwenziwe eCanada, e-United States, e-United Kingdom, e-Australia, eBrazil naseJapan, kanti amanye amaphrojekthi asathuthukiswa. I-Diatomite iyimpushana, ukusetshenziswa komthamo omkhulu; Yayisetshenziselwa ukulawula izilokazane ezigciniwe zokusanhlamvu nokwandisa ukuminyana kwenqwaba yokusanhlamvu. Ijubane lokusanhlamvu nalo lishintshile; Ngaphezu kwalokho, uthuli luyanda, indlela yokwenza izinkomba zezempilo; Zonke lezi zinkinga zidinga ukufundwa futhi zixazululwe. I-China inogu olude kanye nezinsiza eziningi ze-Marine diatomite, ngakho-ke indlela yokuthuthukisa nokusebenzisa lesi sibulala-zinambuzane semvelo ezinambuzaneni ezigcina okusanhlamvu nakho kuyakufanelekela ucwaningo.

I-Diatomiteisebenza ngokuphula “umgoqo wamanzi” walesinambuzane. Ngokufanayo, impushana ye-inert, impushana enezici ezifanayo njenge-diatomite, ingaphinde ibulale izinambuzane ezisanhlamvu ezigciniwe. Izinto ze-inert powder zifaka i-zeolite powder, i-tricalcium phosphate, i-amorphous silica powder, i-Insecto, umlotha wezitshalo, umlotha we-rice chaser, njll. Kodwa lezi zimpushana ezingenasici zisetshenziswa ngemithamo ephezulu kune-diatomite ukulawula izinambuzane zokusanhlamvu ezigciniwe. Isibonelo, i-1 igremu ye-insecticidal powder kufanele isetshenziswe ikhilogremu ngayinye kakolweni; Kudingeka amagremu angu-1-2 we-amorphous silica ngekhilogremu yokusanhlamvu ukubulala izinambuzane ezisanhlamvu ezigciniwe. Kuyasebenza ukusebenzisa i-1000 ~ 2500ppm tricalcium phosphate ukulawula izinambuzane ezisanhlamvu ezigciniwe zemifino. Ukulawula izinambuzane ezisanhlamvu ezigciniwe ngomlotha wezitshalo, kufanele kusetshenziswe u-30% wesisindo sokusanhlamvu. Ezifundweni zakwamanye amazwe, umlotha wezitshalo wawusetshenziselwa ukulawula izinambuzane ezisanhlamvu ezigciniwe. Lapho umlotha wezitshalo ubalelwa ku-30% wesisindo sommbila wawuxutshwa nommbila ogciniwe, umphumela wokuvikela ummbila ezinambuzaneni wawucishe ulingane no-8.8ppm chlorophorus. Kukhona i-silicon elayisi kanye nelayisi, ngakho iphumelela kakhulu kunokusebenzisa umlotha wezitshalo nokhuni ukulawula izinambuzane ezigciniwe zokusanhlamvu.
