Intengo Ethengiswayo Yokulawula Izinambuzane I-Pyriproxyfen I-Pyriproxyfen isitokwe

Incazelo Yomkhiqizo

I-Pyriproxyfen, inhlanganisela yokwenziwa esetshenziswa kabanzi njengomlawuli wokukhula kwezinambuzane (IGR), iyithuluzi elisebenza kahle kakhulu lokulawula izinambuzane ezahlukahlukene. Indlela yayo yokusebenza ehlukile iphazamisa intuthuko evamile yezinambuzane, izivimbele ekufinyeleleni ekuvuthweni nasekuzaleni, ngaleyo ndlela inciphise inani lazo. Lesi sithako esinamandla esisebenzayo sithole ukuthandwa phakathi kwabalimi, ochwepheshe bokulawula izinambuzane, kanye nabaninikhaya ngenxa yokusebenza kwayo okumangalisayo kanye nokuguquguquka.

Ukusetshenziswa

I-Pyriproxyfen isetshenziswa kakhulu kwezolimo nakwezolimo ukulwa nezinambuzane eziningi, okuhlanganisa omiyane, izimpukane, ama-aphid, izimpukane ezimhlophe, ama-thrips, ama-leafhopper, kanye nezinhlobo ezithile zezimbungulu. Le nhlanganisela iphazamisa umjikelezo wokuzala wezinambuzane ngokulingisa i-hormone evimbela ukukhula kwamaphiko azo nezitho zokuzala, okuholela ekungazali kanye nokwehla kwenani labantu.

Isicelo

Njengoketshezi oluhlanganisiwe, i-pyriproxyfen ingasetshenziswa ngezindlela ezahlukene, kuye ngokuthi isinambuzane esiqondiwe kanye nendawo edinga ukwelashwa. Ingafuthwa ngqo ezitshalweni noma emaqabungeni, isetshenziswe njengokwelashwa kwenhlabathi, isetshenziswe ngezinhlelo zokunisela, noma isetshenziswe ngisho nasemshinini wokufutha ukulawula omiyane. Ukuguquguquka kwayo kuvumela izindlela zokusebenzisa eziphumelelayo nezisebenzayo, okwenza ifaneleke kokubili emisebenzini yokulima emikhulu kanye nokunakekelwa kwengadi encane.

Izinzuzo

1. Ukulawulwa Okuqondiwe: I-Pyriproxyfen inikeza ukulawula okuqondiwe kwezinambuzane ngaphandle kokulimaza izinambuzane ezizuzisayo noma izinto eziphilayo ezingaqondiwe. Iphazamisa ngokukhetha inani lezinambuzane, okuholela ekunciphiseni inani lazo ngenkathi kugcinwa ibhalansi ohlelweni lwemvelo.

2. Imiphumela Esele: Enye yezinzuzo ezinkulu ze-pyriproxyfen imiphumela yayo ehlala isikhathi eside. Uma isisetshenzisiwe, ihlala isebenza isikhathi eside, ihlinzeka ngokuvikeleka okuqhubekayo ekuhlaselweni kabusha noma ekusungulweni kwezinambuzane ezintsha.

3. Ubungane Emvelweni: I-Pyriproxyfen ayinabo ubuthi obuncane ezincelisayo nasezinyonini, okwenza kube kuphephile ukuyisebenzisa ezindaweni lapho abantu noma izilwane zingase zihlangane khona nezindawo eziphathwe kahle. Ngaphezu kwalokho, ukuhlala kwayo isikhathi eside endaweni ezungezile kunciphisa ingozi yokwakheka kwamakhemikhali noma ukungcola.
