Uphando lwaseKhanada lubonisa ukuba i-diatomite ineendidi ezimbini eziphambili: amanzi olwandle kunye namanzi acocekileyo. I-diatomite yamanzi olwandle isebenza kakhulu kune-diatomite yamanzi ahlaziyekileyo ekulawuleni izitshabalalisi ezigciniweyo eziziinkozo. Umzekelo, idosi ye-565ppm yanikwa ingqolowa ephathwe ngamanzi olwandle i-diatomite 209, apho iindlovu zerayisi zavezwa iintsuku ezintlanu, okubangele izinga lokufa kwe-90 ekhulwini. Ngamanzi amatsha e-diatomite, phantsi kweemeko ezifanayo, izinga lokufa kweendlovu zerayisi ukuya kwi-90 yepesenti ye-dose ye-1,013 PPM.

Ngenxa yosetyenziso lwexesha elide kunye nolubanzi lwephosphine (PH_3) njengesiqhumiso, isityalo siye sakhula ngokuxhathisa kakhulu kwaye asinakubulawa ngeendlela eziqhelekileyo zokufunxa iphosphine. E-UK, kuphela amayeza okubulala izinambuzane e-organophosphorus akhoyo ngoku ukulawula amangolwane okutya agciniweyo, kodwa ezi zinambuzane zemichiza azisebenzi kwiingolwane ze-acaroid kwiindawo zokugcina iinkozo nakwiindawo zokugcina imbewu yeoli. Phantsi kwemeko yobushushu be-15℃ kunye nokufuma okunxulumene ne-75%, xa ithamo le-diatomite kwiinkozo laliyi-0.5 ~ 5.0 g/kg, iinkuku ze-acaroid zinokubulawa ngokupheleleyo. I-acaricidal mechanism ye-diatomite powder iyafana neyezinambuzane, kuba kukho i-wax ebhityileyo kakhulu (i-cap horn layer) kwi-epidermal layer yodonga lomzimba we-acaroid mites.

Ukusetyenziswa kweidatomiteukulawula izitshabalalisi ezigciniweyo eziziinkozo zaphuhliswa kule minyaka ili-10 idlulileyo. Uphononongo oluneenkcukacha luye lwenziwa eKhanada, eUnited States, eUnited Kingdom, eOstreliya, eBrazil naseJapan, ezinye iiprojekthi zisaphuhliswa. I-Diatomite ngumgubo, ukusetyenziswa kwedosi enkulu; Yayisetyenziselwa ukulawula izitshabalalisi ezigciniweyo eziziinkozo kunye nokwandisa ukuxinana kweenkozo. Isantya sokutya okuziinkozo sitshintshile; Ukongezelela, uthuli luyanda, indlela yokwenza izikhombisi zezempilo; Zonke ezi ngxaki kufuneka zifundwe kwaye zisonjululwe. I-China inonxweme olude kunye nobutyebi obuninzi be-diatomite yaseLwandle, ngoko ke indlela yokuphuhlisa nokusebenzisa esi sitshabalalisi sendalo sokugcina izitshabalalisi eziziinkozo nayo ilufanele uphando.

Diatomiteisebenza ngokwaphula “umqobo wamanzi” wesinambuzane. Ngokufanayo, umgubo we-inert, umgubo oneempawu ezifanayo ne-diatomite, unokubulala izitshabalalisi ezigciniweyo eziziinkozo. Izinto zomgubo we-inert ziquka umgubo we-zeolite, i-tricalcium phosphate, i-amorphous silica powder, i-Insecto, i-vegetation ash, i-rice chaser ash, njl. Ngokomzekelo, i-1 gram ye-insecticidal powder kufuneka isetyenziswe ngekhilogram yengqolowa; Kuthatha i-1-2 grams ye-amorphous silica ngekhilogram yeenkozo ukubulala izinambuzane eziziinkozo ezigciniweyo. Isebenza kakuhle ukusebenzisa i-1000 ~ 2500ppm tricalcium phosphate ukulawula izinambuzane kwingqolowa egciniweyo ye-legumes.Zeolite powder control control in corn corn elephant, ukusebenzisa i-5% yobunzima bombona; Ukulawula izitshabalalisi ezigciniweyo eziziinkozo ngothuthu lwezityalo, kufuneka kusetyenziswe i-30% yobunzima beenkozo. Kwizifundo zangaphandle, uthuthu lwezityalo lwalusetyenziselwa ukulawula izitshabalalisi ezigciniweyo eziziinkozo. Xa uthuthu lwezityalo lubalelwa kwi-30% yobunzima bombona buxutywe nombona ogciniweyo, umphumo wokukhusela umbona kwizinambuzane ezitshabalalisayo wawuphantse ulingane ne-8.8ppm chlorophorus. Kukho i-silicon erayisi kunye nerayisi, ngoko ke iyasebenza ngakumbi kunokusebenzisa isityalo kunye nothuthu lomthi ukulawula izitshabalalisi ezigciniweyo eziziinkozo.
