Hōʻike ka noiʻi Kanada he ʻelua ʻāpana nui ka diatomite: ke kai a me ka wai maʻemaʻe. ʻOi aku ka maikaʻi o ka diatomite wai ma mua o ka diatomite wai maʻemaʻe i ka hoʻopaʻa ʻana i nā pests i mālama ʻia. No ka laʻana, ua hāʻawi ʻia kahi maʻi o 565ppm i ka palaoa i mālama ʻia me ka wai kai diatomite 209, kahi i hōʻike ʻia ai nā elepani raiki no nā lā ʻelima, a he 90 pakeneka ka nui o ka make. Me ka wai hou diatomite, ma lalo o nā kūlana like, ka nui o ka make ʻana o ka elephant raiki i ka 90 pakeneka o ka nui o 1,013 PPM.

Ma muli o ka hoʻohana lōʻihi a me ka hoʻohana nui ʻana o ka phosphine (PH_3) ma ke ʻano he fumigant, ua ulu ka mea kanu i ke kūʻē ikaika iā ia a hiki ʻole ke pepehi ʻia e nā ʻano fumigation phosphine maʻamau. Ma UK, aia wale no ka organophosphorus insecticides i kēia manawa no ka mālama ʻana i nā mites meaʻai i mālama ʻia, akā ʻaʻole maikaʻi kēia mau lāʻau insecticides kemika i nā mites acaroid i loko o nā depot palaoa a me nā waihona hua aila. Ma lalo o ke kūlana o ka mahana 15 ℃ a me ka haʻahaʻa haʻahaʻa 75%, i ka wā o ka nui o ka diatomite i ka palaoa he 0.5 ~ 5.0 g / kg, hiki ke pepehi ʻia nā mites acaroid. ʻO ke ʻano acaricidal o ka pauka diatomite ua like ia me nā ʻōpala, no ka mea, aia kahi ʻāpana wax lahilahi (cap horn layer) ma ka papa epidermal o ka paia kino o nā mites acaroid.

Ka hoohana ana odiatomiteno ka hoʻopaʻa ʻana i nā pests i mālama ʻia i hoʻomohala ʻia i nā makahiki he 10 i hala. Ua hana ʻia nā haʻawina kikoʻī ma Kanada, ʻAmelika Hui Pū ʻIa, United Kingdom, Australia, Brazil a me Iapana, me ka hoʻomohala ʻana o kekahi mau papahana. ʻO ka diatomite he pauka, ka hoʻohana ʻana i ka nui nui; Ua hoʻohana ʻia no ka hoʻomalu ʻana i nā pests i mālama ʻia a hoʻonui i ka nui o ka palaoa. Ua loli pū ka wikiwiki o ka palaoa; Eia kekahi, hoʻonui ka lepo, pehea e hoʻolālā ai i nā hōʻailona olakino; Pono e aʻo ʻia kēia mau pilikia a pau. He kahakai lōʻihi ko Kina a he nui nā kumu waiwai diatomite Marine, no laila, pono e noiʻi pehea e hoʻomohala ai a hoʻohana i kēia insecticide kūlohelohe no nā pest mālama palaoa.

Diatomitehana ma ka uhaki ʻana i ka “paʻa wai” o ka ʻinikena. Pēlā nō, hiki i ka pauda inert, ka pauda me nā waiwai like me ka diatomite, hiki ke pepehi i nā mea ʻino i mālama ʻia. ʻO nā mea pauka inert ka pauka zeolite, tricalcium phosphate, ka pauka silica amorphous, Insecto, lehu mea kanu, ka lehu chaser raiki, a me nā mea ʻē aʻe. No ka laʻana, pono e hoʻohana ʻia ka 1 gram o ka pauka insecticidal no ka kilo palaoa; He 1-2 kalama o ka silica amorphous no ka kilo o ka palaoa e pepehi i na mea ino i malamaia. He mea maikaʻi ke hoʻohana i ka 1000 ~ 2500ppm tricalcium phosphate e hoʻomalu i nā pests i mālama ʻia i ka palaoa o nā legumes. No ka hoʻopaʻa ʻana i nā pests i mālama ʻia me ka lehu mea kanu, pono e hoʻohana ʻia 30% o ke kaumaha o ka palaoa. I nā haʻawina haole, ua hoʻohana ʻia ka lehu mea kanu no ka hoʻopaʻa ʻana i nā pests i mālama ʻia. I ka hui 'ana o ka lehu mea kanu i 30% o ke kaumaha o ke kulina me ke kulina i mālama 'ia, 'ane'ane like ka hopena o ka pale 'ana i ke kulina mai nā mea 'ino me 8.8ppm chlorophorus. Aia ka silikoni i loko o ka laiki me ka laiki, no laila, ʻoi aku ka maikaʻi ma mua o ka hoʻohana ʻana i ka lehu lāʻau a me ka lehu lāʻau e hoʻomalu ai i nā mea ʻino i mālama ʻia.
