Rimwe rematambudziko anogona kuitika kazhinji mubindu nekurima kuvapo kwezvipembenene. Zvipukanana zvizhinji zvinoumbwa nezvipembenene zvinopedzisira zvakuvadza zvirimwa zvedu nekukanganisa zvirimwa zvedu. Mukurwira kupona, zvirimwa zvakawanda zvakagadzira yavo inouraya zvipembenene. Pakati pemamwe makemikari nenzira yechisikigo inogona kuwanikwa kubvisa tupukanana isu tine iyo Pyrethrin.
Muchikamu chino tiri kukuudza zvese zvaunoda kuti uzive nezvePyrethrin, mashandiro ayo uye kushanda kwayo.
Chii chinonzi Pyrethrin
Sezvatambotaura, pane kurwira kuti zvirimwa zvirambe zviripo zvavanofanira kugadzira nzira dzekurwisa zvipembenene. Mimwe yemiti yakwanisa kugadzira yavo inouraya zvipembenene. Mune ino kesitiri kutaura nezve chrysanthemum. Icho chirimwa chekuzvarwa cheDalmatia kubva maruva akanaka anotumbuka akafanana zvakanyanya pakuonekwa kune maruva. Maruva aya anokwanisa kugadzira makemikari anowanikwa zvakasikwa uye anokwanisa kuchengetedza zvipembenene zvinoumba zvipembenene. Izvi zvinoumbwa ne pyrethrin.
Zvinogona kutaurwa kuti Pyrethrin imushonga wezvipembenene wepanyama. Inogona kuwanikwa kubva kumadzinde nemaruva echrysanthemum chirimwa. Iyo mushoma ine zvikamu zvinomwe zvinoshanda zvinodaidzwa cinnerin I na II, jasmoline I na II, uye pyrethrin I na II. Kazhinji 25% yemusanganiswa iyi pyrethrin, ine zvidiki zvidiki zvecinerin uye jasmoline. Izvi ndizvo zvinoshanda zvinokwanisa kuchengetedza tupukanana tunokanganisa zvirimwa zvedu. Kazhinji, iyo pyrethrin musanganiswa inogadzirwa ine zvidiki zvidiki zvecinerin uye jasmoline. Kuti uwane yakanyanya kuburitsa, zvirimwa zvinofanirwa kukohwiwa mushure mekuita maruva. Kana maruva echrysanthemum atounganidzwa, anoomeswa uye kupwanywa vachishandisa zvinonyungudutsa zvakasiyana kuti vabvise mafuta.
Pyrethrin inoshanda
Pyrethrin inoshanda kwazvo kudzora huwandu hwakawanda hwezvipembenene. Ivo havanyanyo shingirira pane ekugadzira zvipembenene, asi achiri anoshanda. Inofanira kutakurwa mupfungwa kuti, ichiva mushonga wechisikigo, inofanira kurwisa zvipembenene neimwe nzira. Chikonzero chikuru Pyrethrin isinganyanyo shingirira inyaya yekuti ine mafotera anogadzikana. Izvi, zvakare, zvinobatsira, nekuti inoonekwa seimwe yehutachiona hwakachengeteka huripo.
Kutenda kune iyo ine iyo ine Photodegradable mhedzisiro, iyo zvakasununguka inoshatisa nekufamba kwenguva uye chiito chezuva rezuva. Aya ndiwo mawaniro atinoita mushonga wechisikigo uyo unoshanda nemazvo, unobata tupukanana tupukanana asi husingasvibise mvura nevhu nekusefa.
Maitiro ekuita
Tichaona kuti ndedzipi nzira huru dzekushandisa idzo Pyrethrin inoshandisa kuti ibudirire kurwisa mhando iyi yezvipukanana zvataurwa pamusoro apa. Ivo vanopatsanurwa pamwe nedzimwe hama dzakagadzirwa dzemhuri yezvipembenene semapirrethroids. Ndezveboka re Modulators eiyo sodium chiteshi uye inoita chiito chakanangana nehurongwa hwehutachiona hwezvipembenene. Morekuru wekuuraya zvipembenene une basa rekutadzisa kuvharwa kwenzvimbo yesodium mune membrane yesero. Nekudzivirira kuvhara kweiyo sodium chiteshi, isu tinowana chinoramba chichienderera chetsinga yekumanikidza. Nenzira iyi, tinoona kuti zvipembenene zvinotanga kudedera zvichienderera mberi nemhedzisiro yerufu.
Rudzi urwu rwezvipembenene runogona kushanda zvese nekubatana uye nekumedza. Mazhinji mafomati ePyrethrin piperonyl butoxide. Icho chikonzero cheichi ndechekuti ine chiito chekubatana, sezvo zviitwa zvezvikamu zviviri pamwe chete zvine mhedzisiro yakawanda pane zvinoitwa neimwe yega zvakasiyana. Inokurudzirwa zvakanyanya kune dzakasiyana siyana tupuka tudiki. Ichi chipembenene chine simba rakakwirira rekushanduka uye huwandu hwekufa hwevanhu kubva kuzvipukanana.
Kunyangwe iine mibairo yakanaka kwazvo, kushandiswa kwayo mukurima zvakanyanya kwakaderera nekuda kwekutsungirira kwayo kushoma. Sezvatakambotaura, ndiwo chaiwo zvipembenene izvo zvinokanganiswa nekuita kwekudzikisira kwezuva. Neichi chikonzero, synthetic pyrethrins yakabuda. Aive akaumbwa akafanana nemamorekuru mamwe asi achitsvaga kukurira kukuru. Sezvatakambotaura nezvekurima kwakadzama umo mune huwandu hwakawanda hwezvirimwa, pamwe iyi haisi iyo inokurudzirwa zvikuru yezvipembenene. Kune rimwe divi, kana tiine zvirimwa zvedu pachezvedu, tinogona kutora mukana wechiitiko ichi kuitira kuti tisasvibisa mvura nevhu uye tiwane zvirimwa zvirinani.
Neyakagadzirwa synthesized Pyrethrin, zvinokwanisika kushanduka kubva chigadzirwa chaicho uye chisina mhaka kune chinotyisa chakagadzirwa chemhuka nemhuka. Nekuda kweizvi, zviitiko zvakawanda zvekugadzirwa kwemushonga wezvipembenene zvakataurwa. Ichi ndicho chimwe chezvikonzero nei zvichikosha kusimudzira dzimwe nzira dzekudzivirira zvipembenene dzakachengeteka uye dzinochengetedza zvakatipoteredza. Uyezve, zvakakosha kuti mashandiro enguva refu emishonga iyi yezvipembenene akamboedzwa nekudzidzwa.
Main inoshandisa
Tinoziva kuti iko kushandiswa kukuru kwePyrethrin kuparadza tupukanana. Izvi zvinokonzerwa nehukuru hwayo hwekubaya uye yakanaka yekufa mwero iyo yainayo. Mishonga iyi yainzi mhondi. Dzimwe sosi dzinoratidza kuti yaizivikanwa kuChina kweanenge makore chiuru BC Kushandiswa panguva iyoyo yainyanya kutarisisa kudzora inda dzemusoro muvanhu.
Pakangotanga mwaka weindasitiri, kushandiswa kwePyrethrin kwakadzikira nekukurumidza nechitarisiko cheDDT nezvimwe zvinogadzirwa. Nekudaro, munguva dzazvino kushanda kwayo kwakaratidzirwa pane ese marudzi ezvipembenene. Dzimwe fomati dzinogona zvakare kushandiswa kubatsira mukudzivirira mburwa, nhata uye kudzora zvikwekwe muimbwa, kitsi, uye huku.
Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezve Pyrethrin nehunhu hwayo.
