Kafukufuku wa ku Canada amasonyeza kuti diatomite ili ndi magulu awiri akuluakulu: madzi a m'nyanja ndi madzi abwino. Diatomite ya m'madzi a m'nyanja ndiyothandiza kwambiri kuposa diatomite yamadzi am'madzi poletsa tizilombo tosungidwa. Mwachitsanzo, mlingo wa 565ppm unaperekedwa kwa tirigu wogwiritsidwa ntchito ndi madzi a m'nyanja, diatomite 209, momwe njovu za mpunga zinawululidwa kwa masiku asanu, zomwe zinachititsa kuti 90 peresenti ya imfa. Ndi madzi abwino a diatomite, pansi pamikhalidwe yomweyi, kufa kwa njovu za mpunga kumafika 90 peresenti ya mlingo wa 1,013 PPM.

Chifukwa chogwiritsa ntchito phosphine (PH_3) kwanthawi yayitali ngati chofukiza, mmerawo wayamba kukana kwambiri ndipo sungathe kuphedwa ndi njira zodziwika bwino za phosphine. Ku UK, mankhwala ophera tizilombo a organophosphorus okha omwe akupezeka kuti athe kuwongolera nsabwe za m'masamba zosungidwa, koma mankhwala ophera tiziromboti sagwira ntchito motsutsana ndi nthata za acaroid m'malo osungiramo tirigu ndi malo osungira mbewu zamafuta. Pansi pa kutentha kwa 15 ℃ ndi chinyezi wachibale 75%, pamene mlingo wa diatomite mu tirigu unali 0.5 ~ 5.0 g/kg, nthata za acaroid zimatha kuphedwa kwathunthu. Njira ya acaricidal ya ufa wa diatomite ndi yofanana ndi ya tizilombo, chifukwa pali phula lochepa kwambiri (kapu nyanga wosanjikiza) mu epidermal wosanjikiza wa khoma la thupi la nthata za acaroid.

Kugwiritsa ntchitodiatomitekuletsa kusungidwa mbewu tizirombo anapangidwa mu zaka 10 zapitazi. Maphunziro atsatanetsatane achitika ku Canada, United States, United Kingdom, Australia, Brazil ndi Japan, pomwe mapulojekiti ena akukonzedwabe. Diatomite ndi ufa, kugwiritsa ntchito mlingo waukulu; Amagwiritsidwa ntchito kuwongolera tizilombo tosungidwa ndikuwonjezera kuchuluka kwa tirigu. Kuthamanga kwambewu kunasinthanso; Kuonjezera apo, fumbi limakula, momwe mungapangire zizindikiro za thanzi; Mavuto onsewa amafunika kuwaphunzira ndi kuwathetsa. China ili ndi gombe lalitali komanso zopezeka zambiri za Marine diatomite, kotero momwe mungapangire ndikugwiritsa ntchito mankhwala ophera tizilombo achilengedwewa kuti tizirombo tosungira mbewu nawonso tifufuze.

Diatomiteamagwira ntchito pophwanya “chotchinga madzi” cha tizilombo. Mofananamo, ufa wa inert, ufa wokhala ndi zinthu zofanana ndi diatomite, ungathenso kupha tizilombo tosungidwa. The inert ufa zipangizo monga zeolite ufa, tricalcium phosphate, amorphous silica ufa, Insecto, zomera phulusa, mpunga chaser phulusa, etc. Koma inert ufa amenewa ntchito mlingo waukulu kuposa diatomite kulamulira osungidwa mbewu tizirombo. Mwachitsanzo, 1 gramu ya ufa wophera tizilombo iyenera kugwiritsidwa ntchito pa kilogalamu ya tirigu; Pamafunika magalamu 1-2 a silika amorphous pa kilogalamu imodzi yambewu kuti aphe tizirombo tosungidwa. Ndizothandiza kugwiritsa ntchito 1000 ~ 2500ppm tricalcium phosphate kuwongolera tizirombo m'nthaka yosungidwa ya nyemba za nyemba.Zeolite ufa kuwononga chimanga njovu, kugwiritsa ntchito 5% ya kulemera kwa chimanga; Pofuna kuthana ndi tizilombo tosungidwa ndi phulusa la zomera, 30% ya kulemera kwa tirigu iyenera kugwiritsidwa ntchito. M'maphunziro akunja, phulusa la chomera lidagwiritsidwa ntchito poletsa tizirombo tambirimbiri. Pamene chomera phulusa nkhani 30% ya kulemera kwa chimanga anali wosakanizidwa kusungidwa chimanga, zotsatira za kuteteza chimanga ku tizirombo anali pafupifupi wofanana 8.8ppm chlorophorus. Mumpunga muli silicon ndi mpunga, choncho ndi othandiza kwambiri kuposa kugwiritsa ntchito phulusa lamitengo ndi mitengo pothana ndi tizirombo tosungidwa.
