Ka pilina ma waena o ka nui o ke kinoea sulfuryl fluoride a me ka paʻa ʻana o ka ea o ka hale kūʻai

Hiki i ka hapa nui o nā mea hoʻoheheʻe ahi ke hoʻokō i ka hopena like o ka insecticidal ma ka mālama ʻana i kahi manawa pōkole ma kahi kiʻekiʻe a i ʻole ka manawa lōʻihi ma kahi haʻahaʻa. ʻO nā kumu nui ʻelua no ka hoʻoholo ʻana i ka hopena insecticidal ʻo ia ka noʻonoʻo kūpono a me ka manawa mālama noʻonoʻo kūpono. ʻO ka hoʻonui ʻana i ka noʻonoʻo o ka mea hana ʻo ia hoʻi ka hoʻonui ʻana i ke kumukūʻai o ka fumigation, he mea waiwai a kūpono hoʻi. No laila, ʻo ka hoʻolōʻihi ʻana i ka manawa fumigation e like me ka hiki he ala kūpono ia e hōʻemi ai i ke kumukūʻai fumigation a mālama i ka hopena insecticidal.

ʻO nā kaʻina hana fumigation e kuhikuhi ana i ka paʻa o ka ea o ka hale kūʻai e ana ʻia e ka hapalua ola, a ʻo ka manawa no ke kaomi e hāʻule ai mai 500Pa a i 250Pa he ≥40s no nā hale kūʻai pālahalaha a me ≥60s no nā hale kūʻai poepoe papau e hoʻokō ai i nā koi fumigation. Eia nō naʻe, ʻaʻole maikaʻi ka paʻa o ka ea o nā hale kūʻai o kekahi mau ʻoihana mālama, a he paʻakikī ke hoʻokō i nā koi paʻa o ka ea o ka fumigation. ʻO ka hanana o ka hopena insecticidal maikaʻi ʻole e hana pinepine ʻia i ka wā o ke kaʻina hana fumigation o ka palaoa i mālama ʻia. No laila, e like me ka paʻa o ka ea o nā hale kūʻai like ʻole, inā koho ʻia ka nui kūpono o ka mea hana, hiki iā ia ke hōʻoia i ka hopena insecticidal a hoʻemi i ke kumukūʻai o ka mea hana, he pilikia wikiwiki ia e hoʻoponopono ʻia no nā hana fumigation āpau. No ka mālama ʻana i ka manawa kūpono, pono ka hale kūʻai i ka paʻa maikaʻi o ka ea, no laila he aha ka pilina ma waena o ka paʻa o ka ea a me ka nui o ka mea hana?

Wahi a nā hōʻike pili, i ka wā e hiki ai ke ea paʻa o ka hale kūʻai i 188s, ʻo ka hapalua ola lōʻihi loa o ka sulfuryl fluoride ma lalo o 10d; i ka wā e 53s ai ke ea paʻa o ka hale kūʻai, ʻo ka hapalua ola lōʻihi loa o ka sulfuryl fluoride ma lalo o 5d; i ka wā e 46s ai ke ea paʻa o ka hale kūʻai, ʻo ka hapalua ola pōkole loa o ka sulfuryl fluoride ma ka lōʻihi loa he 2d wale nō. I ka wā o ke kaʻina hana fumigation, ʻo ke kiʻekiʻe o ka sulfuryl fluoride, ʻo ka wikiwiki o ka palaho, a ʻoi aku ka wikiwiki o ka palaho o ke kinoea sulfuryl fluoride ma mua o ke kinoea phosphine. ʻOi aku ka ikaika o ka permeability o ka sulfuryl fluoride ma mua o ka phosphine, e hopena ana i ka hapalua ola pōkole o ka gas ma mua o ka phosphine.

Sulfuryl fluorideLoaʻa i ka fumigation nā ʻano o ka insecticide wikiwiki. ʻO ka nui o ka make o kekahi mau mea ʻino nui i mālama ʻia e like me nā pepeke palaoa pālahalaha lōʻihi, nā pepeke palaoa saw-saw, nā weevils kulina, a me nā ʻuku puke no 48h fumigation ma waena o 2.0 ~ 5.0g / m '. No laila, i ka wā o ke kaʻina hana fumigation, ʻo kasulfuryl fluoridepono e koho pono ʻia ka hoʻohuihui e like me nā ʻano pepeke i loko o ka hale kūʻai, a hiki ke hoʻokō ʻia ka pahuhopu o ka pepehi kanaka wikiwiki.

Nui nā kumu e hoʻopilikia ai i ka wikiwiki o ka palaho ʻana okinoea sulfuryl fluorideka nui o ka waihona i loko o ka hale kūʻai. ʻO ke kūpaʻa o ka ea o ka hale kūʻai ke kumu nui, akā pili pū kekahi i nā mea e like me ke ʻano o ka palaoa, nā haumia, a me ka porosity o ka puʻu palaoa.
