Ndinotaura nezve zvinotevera zvemadhumo eka dzaite kumusoro wechikamu chete uye achiziva kuti akashanda pakati pekuti haachishandiswa? Ushandiswa nedenderera anogara nhasi kana ndokumbonzisa mashongedzero? Kana pakati pazvoita munyika wakasimba kuti ushawaridze madhumo arova kuhama nemadhumo emadhumo akashandiswa pamwe nezviripo rakazhinjiwa rwezvidii dzemadhumo dzakaipa? Cherechedza pyrethrins ne pyrethroids kuti vashandi! Zvakaitwa zvese zvinotevera madhumo uye zvinoti zvakashandiswa nemusoro wesvikiro, madzimai kana masvosve enhamo yekurima. Tatambudzira zivei zvakare zvinotevera, nezviito zvekuvarwa nekuparadziswa... zvakaitwa zvisine chikoshero pasi nemusha.
Pyrethrins — vanhu vachazvino mumaburiti echembere pyrethrum. Iyo ndiyo chembere chakaita chinhu chekushanda pachena pakuti pane madzimai emadhara akashandiswa kubva mazuva yakarega kuti vakawana kuenda kusanganisa nhaka dzavo. Pyrethrins vakasunungura manhe ari kwezvidhoma pamusoro pane, vazokanganisa uye zvakanyorwa zvekugona. Pyrethrins vadziwa nekudziwa rwatiro rakadaro — vachazvino mumwe munamiriri yemizvo! Vadziwisisa nhaka yacho yakapfuura kuti yakagadziriswa pakutanga kumisodzi Egypt. Vakadiwa nekuti pane nhaka yakarega yakarima kuti yakakosha kuti yakakosheshe kubva maso anopfuura.
Pero, pakati pemaera pasi pane pyrethroids! Ndiyani Pyrethroids?: Pyrethrins nechimiro chinhu chinogona kugara pakutsvaga, panonzi pyrethroids ndichinhu chachakatanga manja akashandiswa nguva yakarema, yacho yakasarudzwa kuti ruzha zvinotevera mabasa nemadongokore. Vashandi vakaenda kuvarira nekuti vanotarisa mumwe nevakapiwa 1960s kusanganisira chinhu chekurima kubva chemoto, muchinhu chinosunungurwa. Pyrethroids: Pakushaya kwavo achitamba nePyrethrins, ndizvo zvinotevera kuti haizvozviuru nemazvidyo, asi vakasunungurwa nguva yakarema, yakakosha kuti chinhu chinoshandiswa nguva yakarema yakapfuura pamusoro nemadongokore - ichikoshiri kuti chinhu chinonyorwa chinoshandiswa.
Zviripo nezviitiko zvinoita pyrethrins uye zviitiko zvinoshanda kubva kana pyrethroids, zvinotevera kuti zvinoshandiswa pakati. Vanhu vese vari kugara kuti vakashandiswa kuti vanovamwa nekutambudzika mazuva yemadhumo edziite uye madhumo edziiita nemadhumo emabasa akaitikira, uye kuve chete chemadhumo echiri kuchekwaira. Chero chaizvo chinotevera kuti zvinonzi kuti zvinoshamwa mumwe nevanhu uye masvosve, ndichinotarisa kuti zvinoshandiswa zvakawanda sechiripo chemikashi chine chete ichiiti ichiurayi kuti unoshandiswa. Pakuitika, zvizvo zvinoshandiswa zvinotevera kuti zvinobudirira muenviriondo itacho inoziva kuti zvinoshandiswa zvinoratidza zvisine zvakanaka mumhara wezvidzidziro uye zvinokanganisa zvishandiswa zvemhara.
Pero, ndichidzivirira zvinotevera zvakawanda zvachiona kubva pakati pavanhu. Zviripo zvemazithandikitsa pyrethrins pazvoita kuti vashandiye vanoshandiswa marara anopfuura nekuti vakaitika kugadzirisa mapoto, pane zveito. Pero, kana vakaitika kugadzirisa makore akaitika kuti vakagadziriswe, vakasunungurwa nezviitiko dzakaitika kuti vakabuda amai nevanhu vanogona kuti vakabudise masunungurwi anoita kuti vakabudise masunungurwi (masunungurwi achiriwo chete achigadziriswa) Kusanganisi kana pyrethroids vanoratidza mapiro nemavara uye mavara akaitika kuti vakagadziriswe, vakaitika kuti vakabudise masunungurwi anotarisa nemapiro, pane ichi ichiriwo ichigadziriswa.
Pyrethrins ne pyrethroids zvinoshanda mumwe munhu wechiseyi chete pakare kwezviratidzo zvemombe anenge zvakawanda. Zvipi zvine zvisakafanirwa nemakomo kuti zvichinziresha masviyo ne madenderedzero akashandiswa pamusoro pavanhu. Amaruzhinji, nevanhu vakasimudza mhesi vekuti vanhu vese vachitamba kuti zvinotarisa masviyo ne madenderedzero akashandiswa kuti hazvienzane kuwana kubva kumadziva anenge akashandiswa. Zvipi zvine zvisakafanirwa kuti zvinotarisa masviyo ne madenderedzero akashandiswa kuti hazvienzane kuchera makomo yakazvarwa nemamusoro wemombe yacho yakapfuura, uye kune mamombe emombe yepfupi, pfupi yekurima yekunyika yakapfuura yakaitika kuti iwe ndiani achii.
Unogona kugadzira masvomhu akashandisiswa pamusoro wepyrethrins ne pyrethroids nyaya pakati pachena. Chete chacho chinoshandiswa mumasawo mashure nekuti vanenge vashure vari vakakosha kuti vashure vari vechero chauro kwevanhu, pano ants, cockroaches, mosquitoes nemanyorwa. Pakare kwechikanganiso, masvomhu ari kushandisa kuti tichive nechikanganiso chekurudzi chenyanje, ichi chinenge chinotenderwa nevanhu vese. Vanogona kubva nekuti vakabuda mazita ane zvinotevera kuti vapfuura pazvikamu here? Vapfuura vamwe vanogona kugadzirisa mapetsi nechimiro chemagadhiro yakakosha kuti vashure vari vakakosha kuti vashure vari vechero chauro kwevanhu, pano ants, cockroaches, mosquitoes nemanyorwa. Pakare kwechikanganiso, masvomhu ari kushandisa kuti tichive nechikanganiso chekurudzi chenyanje, ichi chinenge chinotenderwa nevanhu vese. Vanogona kubva nekuti vakabuda mazita ane zvinotevera kuti vapfuura pazvikamu here? Vapfuura vamwe vanogona kugadzirisa mapetsi nechimiro chemagadhiro yakakosha kuti vashure vari vakakosha kuti vashure vari vechero chauro kwevanhu.
Tashanu masvigu a pyrethrins ne pyrethroids ekusvika kusanganisi kune mabasa akaita muhurira kuti pindirwe nemazuva yemadenderedzwa yakakosha pakati pekugara nhasi nokuti kuenda kudya. Iyo ichigwaniriswa pamwe chete nemisodzi yakakosha uye nemasvosve yakakosha ekugara nhasi pakati pekugara nhasi. Pakuita 26 miaka kuti mashandiro anoshandiswa nekushaya, zvinhu dzake dzinotarisa mumwe munyika dzinoita 10,000+ tons. Pamwe chete, zvinhu zinoshandiswa nezviitiko zvakawanda 60+, zvinhu zine masvigu emazano nemagadziridzo yakakosha uye vanobatsira kuti vachimbisane nemwe wemwe.
Ronch inotiuna masvigu a pyrethrins ne pyrethroids pakati pemamwe munyika ekugara nhasi. Inotiuna makore angare muchitiro chesvika nemamwe munyika ekugara nhasi. Nekuziviswa pakuti pane kunze kwevanhu uye kuti mashandiro anoshandiswa, tichitarise masvigu akakosha uye mashandiro akakosha, tizovhimwa zvinhu dzakakosha nemimwe munyika, tizokwira kumusoro wesvikiro semabhuru ekugara nhasi, uye tizovhimwa masvigu akakosha ekugara nhasi.
Ronch inotanga masviga emasango eva kusanganisira projekti. Iwe vanenge vachirema kuti vakadzi vese vari pashure nekushandiswa pakati panobuda uye zvinotevera mazano maviri ane makore kuti kuziva zvakaitwa nezvekuitika nemakore akaitika pamwe chete. Masviga asi akaitwa nekukura kuWorld Health Organization. Masviga asi akaitwa nekukura kune masango ekurima, iwe vanenge vachiratidza vachishandiswa vese vari pasi, ichi chinenge chinoshandiswa nezvirimwi zvemisi, pane zvitsva uye pyrethrins nekuti pyrethroids.
Ronch inotanga kubva chinhu chacho chepyrethrins nezve pyrethroids, achirwana nhengozi dzekushanda kurowa pasi. Iyo ichibva nemakiti echiiyi market, ichizvoita zvishoma zvekugara nemakore emasango emanja uye nemusoro wezvipfupfu, ichifanira pakutsvaga zvinhu dzemukurima dzemaisa nezvisine kuti kuzoita zvinhu dzemaisa nezvimwe zvinhu dzemaisa dzinoshandiswa ndechidiki kuti kuzokanganisa nokuti kunopfungwa pamwe chete nemaisa, achitamba kuti akashaya masvosero aya nemaisa anozivikanwa, achitamba kuti akashaya masvosero aya nemaisa anozivikanwa, achitamba kuti akashaya masvosero aya nemaisa anozivikanwa.
