ʻO ka palaoa i mālama ʻia ma hope o ka ʻohi ʻana, inā i mālama ʻia i loko o ka hale waihona palaoa a i ʻole i ka home o ka poʻe mahiʻai, inā mālama pono ʻole ʻia, e hoʻopilikia ʻia e nā pests i mālama ʻia. Ua loaʻa i kekahi poʻe mahiʻai nā poho koʻikoʻi ma muli o ka loaʻa ʻana o nā pests palaoa i mālama ʻia, me kahi kokoke i 300 pests no kilokani palaoa a me ka pohō kaumaha o 10% a ʻoi aku paha.

ʻO ke olaola o ka mālama ʻana i nā pests ʻo ia ke kolo mau i loko o ka puʻu palaoa. Aia kahi ala e hoʻomalu ai i nā meaʻai meaʻai i mālama ʻia me ka hoʻohana ʻole ʻana i nā pesticides synthetic i loaʻa i nā hopena olakino a me ke olakino kanaka? ʻAe, he diatomite ia, he insecticide kūlohelohe i hoʻohana ʻia no ka mālama ʻana i nā mea ʻōpala palaoa. ʻO ka diatomite kahi waihona honua i hoʻokumu ʻia mai nā iwi mōʻalihaku o nā mea ola hoʻokahi o ka moana a me ka wai maʻemaʻe, ʻo ia hoʻi nā diatoms a me nā algae. He ʻelua miliona makahiki kēia mau waihona. Hiki ke kiʻi ʻia ka pauka diatomite o ka maikaʻi ma ka ʻeli ʻana, ka ʻoki ʻana a me ka wili. Ma ke ʻano he insecticide kūlohelohe, ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana i ka pauka diatomite a loaʻa ka manaʻo hoʻohana ākea i ka hoʻomalu ʻana i nā pests i mālama ʻia. He waiwai ʻo Diatomite i nā kumuwaiwai kūlohelohe, ʻaʻohe mea ʻawaʻawa, ʻala ʻole a maʻalahi hoʻi e hoʻohana. No laila, ua paipai ʻia e hoʻohana ʻia i nā wahi kuaʻāina e hana i kahi ala hou no ka mālama ʻana i nā pests o ka palaoa i mālama ʻia ma nā kuaʻāina. Ma waho aʻe o ka mana absorption maikaʻi, ʻo ka nui o ka ʻāpana, ka like ʻole, ke ʻano, ka waiwai pH, ka ʻano dosage a me ka maʻemaʻe o ka diatomite nā mea nui e pili ana i kāna hopena insecticidal. ʻO ka diatomite me ka hopena insecticidal maikaʻi he silika amorphous maʻemaʻe me ke anawaena ʻāpana <. ʻO 10μm(micron), pH <8.5, loaʻa i kahi pālolo liʻiliʻi wale nō a emi iho ma mua o 1% silika crystalline.

Ua aʻo ʻia nā ʻano mea like ʻole e pili ana i ka pauka diatomite i ka mālama ʻana i nā pests palaoa i mālama ʻia ma ʻAmelika Hui Pū ʻIa: ʻano dosage, dosis, hoʻāʻo i nā ʻano pepeke, ke ʻano pili ma waena o nā pests a me ka diatomite, ka manawa hoʻopili, ke ʻano o ka palaoa, ke ʻano o ka palaoa (ka palaoa holoʻokoʻa, ka palaoa haʻihaʻi, ka pauka), ka mahana a me ka wai o ka palaoa, a pēlā aku.

No ke aha e hiki ai i ka diatomite ke pepehi i nā mea ʻino i mālama ʻia?

ʻO kēia no ka mea he ikaika ikaika ka pauka diatomite e komo i nā esters. ʻO ke kino o ka pest mālama ʻana i ka palaoa he ʻeleʻele ka ʻili a he nui nā bristles. Holoi ka pauda diatomite i ka ʻili o ke kino o ka ʻōpala palaoa i mālama ʻia i kona kolo ʻana i ka palaoa i mālama ʻia. ʻO ka papa waho loa o ka paia o ke kino o ka pepeke i kapa ʻia he epidermis. Aia i loko o ka epidermis kahi ʻāpana lahilahi o ka wax, a ma waho o ka papa wax he ʻāpana lahilahi o ka wax i loaʻa nā esters. ʻOiai he lahilahi loa ka papa wax a me ka pale wax layer, he mea koʻikoʻi loa lākou i ka mālama ʻana i ka wai i loko o ke kino o ka ʻinikena, ʻo ia ka "paʻa wai" o ka inike. ʻO ia hoʻi, hiki i ka "paʻa wai" ke mālama i ka wai i loko o ke kino pepeke mai ka hoʻohū ʻana a ola. Hiki i ka pauka diatomite ke komo ikaika i nā esters a me nā waxes, e hoʻopau ana i ka "paʻa wai" o nā pests, e hoʻolilo iā lākou i ka wai, lilo ke kaumaha a make.
