Aluminom phosphide na-arụ ọrụ nke ọma n'igbu ụmụ ahụhụ n'ihi ntọhapụ nke gas na-egbu egbu nke a na-akpọ phosphine (PH3) mgbe ọ na-abanye na mmiri mmiri, karịsịa ikuku mmiri ma ọ bụ iru mmiri na gburugburu ebe obibi.

Ụdị omume nke phosphine gas bụ isi site n'ikike ya ịkpaghasị usoro iku ume cell na pests, na-eduga na ọnwụ ha.

Ụdị omume

Nke a bụ nkọwa zuru ezu nke ka aluminom phosphide si arụ ọrụ:

1. Mwepụta nke phosphine gas:
   • Aluminom phosphide na-adịkarị n'ụdị pellets ma ọ bụ mbadamba.
   • Mgbe ekpughere ya na mmiri, dị ka iru mmiri ikuku ma ọ bụ mmiri dị na gburugburu ebe ebumnuche, aluminom phosphide na-emeghachi omume iji hapụ gas phosphine (PH3).
   • Mmeghachi omume na-eme dị ka ndị a: Aluminom phosphide (AlP) + 3H2O → Al (OH) 3 + PH3.
2. Ụdị omume:
   • Phosphine gas (PH3) na-egbu egbu nke ukwuu maka ụmụ ahụhụ, gụnyere ụmụ ahụhụ, òké na ụmụ ahụhụ ngwaahịa ndị ọzọ echekwara.
   • Mgbe ụmụ ahụhụ batara na gas phosphine, ha na-amịnye ya site na usoro iku ume ha.
   • Phosphine gas na-egbochi usoro iku ume cell na pesti site na igbochi ọrụ enzymes maka mmepụta ume (kpọmkwem, ọ na-akpaghasị agbụ ụgbọ njem mitochondrial electron).
   • N'ihi ya, pests enweghị ike ịmepụta adenosine triphosphate (ATP), nke dị mkpa maka ike cellular, na-eduga n'ịgwọ ọrịa metabolic na n'ikpeazụ ọnwụ.
3. Ọrụ Broad-Spectrum:
   • Phosphine gas nwere ụdị ọrụ dị iche iche, nke pụtara na ọ nwere ike ijikwa ụdị ahụhụ dị iche iche, gụnyere ụmụ ahụhụ, nematodes, òké na ụmụ ahụhụ ndị ọzọ a na-ahụ n'ime ọka, ngwa ahịa, na ihe owuwu echekwara.
   • Ọ dị irè megide ụdị pests dị iche iche, gụnyere àkwá, larvae, pupae, na ndị okenye.
   • Gas phosphine nwere ikike iji banye site na ihe ndị na-asọ oyi, na-erute ebe zoro ezo ma ọ bụ nke siri ike iru ebe ụmụ ahụhụ nwere ike ịnọ.
4. Ihe gbasara gburugburu:
   • Ntọhapụ nke phosphine gas sitere na aluminom phosphide na-emetụta ihe gburugburu ebe obibi dị ka okpomọkụ, ọdịnaya mmiri, na ọkwa pH.
   • Okpomọkụ dị elu na ọkwa mmiri na-eme ka mwepụta nke gas phosphine dịkwuo elu, na-eme ka ọ dị irè n'ịchịkwa ụmụ ahụhụ.
   • Otú ọ dị, oke mmiri mmiri nwekwara ike ibelata nrụpụta nke gas phosphine, n'ihi na ọ nwere ike imeghachi ya ngwa ngwa ma mee ka ọ ghara ịdị irè.
