Imidaclopridiyisibulala-zinambuzane esisebenza nge-nitromethylene, esiyingxenye yesibulala-zinambuzane esibizwa nge-chlorinated nicotinyl, esaziwa nangokuthi isibulala-zinambuzane se-neonicotinoid, esinefomula yamakhemikhali i-C9H10ClN5O2. Ine-spectrum ebanzi, ukusebenza kahle okuphezulu, ubuthi obuphansi kanye nensalela ephansi, futhi akulula ukuthi izinambuzane zikhule ukumelana. Ingaphazamisa uhlelo olujwayelekile lwezinzwa zezinambuzane, yenze ukudluliselwa kwezimpawu zamakhemikhali kwehluleka, futhi ibangele ukukhubazeka nokufa kwezinambuzane.
Lo mkhiqizo unomthelela omuhle osheshayo, futhi unomthelela omkhulu wokuvimbela ngosuku olulodwa ngemva komuthi, kanti isikhathi esisele singangezinsuku ezingu-25. Usetshenziswa kakhulu ukulawula izinambuzane ezimunca ngokubhoboza.
Ukulawula izinambuzane ezimunca izimbobo kanye nezinhlobo zazo ezimelana nazo. Inezici ezilandelayo:
(1) Umphumela obanzi, osebenza kahle kakhulu futhi ohlala isikhathi eside. Unomphumela omuhle kakhulu wokulawula kuma-aphid, ama-leafhopper kanye nezinye izinambuzane zezingxenye zomlomo ezimunca izimbobo kanye nezinambuzane ze-coleopteran. Ungasetshenziswa futhi ukulawula izintuthwane ezakhiweni kanye nezinambuzane ezifuywayo njengekati nezinja. Ngokuvamile, amagremu angu-1-2 ezithako ezisebenzayo angasetshenziswa nge-1 year ukuthola imiphumela yokulawula eyanelisayo, futhi isikhathi esisebenzayo singahlala amasonto ambalwa. Ukusetshenziswa okukodwa kungavikela ezinye izitshalo ezinambuzaneni phakathi nesizini yonke yokukhula.
(2) Ifaneleka kakhulu ekwelapheni inhlabathi nembewu. Ine-poisoning esiswini kanye nemiphumela yokubulala izinambuzane. Ukwelapha inhlabathi noma imbewu nge-imidacloprid, ngenxa yezakhiwo zayo ezinhle zesistimu, ama-metabolites ngemuva kokumuncwa yizimpande zezitshalo nokungena ezitshalweni anomsebenzi ophezulu wokubulala izinambuzane, okungukuthi, i-imidacloprid kanye nama-metabolites ayo ngokubambisana adlala umphumela wokubulala izinambuzane, ngakho-ke umphumela wokulawula usebenza kahle kakhulu. I-Imidacloprid ingaxutshwa nama-fungicides uma isetshenziselwa ukwelashwa kwembewu.
(3) Indlela esebenza ngayo isenzo sokubulala izinambuzane ihlukile. Iyisithako sezinzwa, futhi inhloso yayo yi-nicotinic acid acetylcholinesterase receptor kulwelwesi lwe-post-synaptic lwesimiso sezinzwa sesilokazane, esiphazamisa ukukhuthazwa okuvamile kwesimiso sezinzwa sesilokazane, okuholela ekukhubazekeni nasekufeni. Lokhu kuhlukile kuma-insecticide avamile. Ngakho-ke, ezinambuzaneni ezingamelani ne-organophosphorus, i-carbamate, kanyeizibulala-zinambuzane ze-pyrethroid, i-imidacloprid isenomphumela ongcono wokulawula. Inokubambisana okusobala uma isetshenziswa noma ixutshwe nalezi zinhlobo ezintathu zezibulala-zinambuzane.
(4) Kulula ukubangela izinambuzane ukuthi zikhule ukumelana nemithi. Ngenxa yendawo yazo yokusebenza eyodwa, izinambuzane zivame ukuba nokumelana nayo. Ukuvama kokusetshenziswa kufanele kulawulwe ngesikhathi sokusetshenziswa. Akuvunyelwe ngokuphelele ukuyisebenzisa kabili kulandelana esitshalweni esifanayo. Ezinye izinhlobo zezibulala-zinambuzane.
