I-Flonicamidiyisibulala-zinambuzane i-pyridine amide (noma i-nicotinamide) esitholwe yi-Ishihara Sangyo Co., Ltd. yaseJapan. Ingalawula ngempumelelo izinambuzane ezimunca ukubhoboza ezitshalweni eziningi, futhi inomphumela omuhle wokungena, ikakhulukazi kuma-aphid. Isebenza kahle. Indlela esebenza ngayo intsha, ayinawo ukumelana nezinye izibulala-zinambuzane ezithengiswa emakethe njengamanje, futhi inobuthi obuphansi ezinyosini.
Ingangena kusukela ezimpandeni kuya eziqwini nasemaqabungeni, kodwa ukungena kusukela emaqabunga kuya eziqwini nasezimpandeni kubuthakathaka kakhulu. I-ejenti isebenza ngokuvimbela isenzo sokumunca se-enambuzane. Izinambuzane ziyayeka ukumunca ngokushesha ngemva kokudla i-pesticide, futhi ekugcineni ziyafa yindlala. Ngokusho kokuhlaziywa kwe-elekthronikhi kokuziphatha kokumunca izinambuzane, le ejenti ingenza izicubu zenaliti zomlomo zezinambuzane ezimuncayo ezifana nama-aphid zingakwazi ukufaka ezicutshini zezitshalo futhi zisebenze kahle.
Indlela yokusebenza kwe-flonicamid kanye nokusetshenziswa kwayo
I-Flonicamid inendlela entsha yokusebenza, futhi inobuthi obuhle be-neuro kanye nomsebenzi osheshayo wokuvimbela ukondla ngokumelene nezinambuzane ezimunca ngokubhoboza njenge-aphid. Umphumela wayo wokuvimba izinaliti ze-aphid wenza ifane ne-pymetrozine, kodwa ayikhulisi ukufinyela okuzenzakalelayo kwesikhonyane esifudukayo njenge-pymetrozine; inobuthi be-neuro, kodwa iyisisulu esivamile sezinto ezibangela izinzwa i-Acetylcholinesterase kanye nama-receptor e-nicotinic acetylcholine awanayo imiphumela. I-International Action Committee on Insecticide Resistance ihlukanise i-flonicamid ku-Category 9C: Ama-Selective Homopteran Antifeedants, futhi yilona kuphela ilungu laleli qembu lemikhiqizo. “Ilungu elilodwa” lisho ukuthi alinawo ukumelana nezinye izibulala-zinambuzane.
I-Flonicamid iyakhetha, iyasebenza, inomphumela oqinile we-osmotic, futhi inomphumela ohlala isikhathi eside. Ingasetshenziswa ezihlahleni zezithelo, okusanhlamvu, amazambane, ilayisi, ukotini, imifino, ubhontshisi, ukhukhamba, ama-eggplant, amakhabe, izihlahla zetiye kanye nezitshalo zokuhlobisa, njll. Ukulawula izinambuzane ezimunca umlomo, njenge-aphid, izimpukane ezimhlophe, izintethe ezinsundu, ama-thrip kanye nezintethe zamaqabunga, njll., phakathi kwazo enemiphumela ekhethekile kuma-aphid.
Izici ze-Flonicamid:
1. Izindlela ezahlukene zokwenza. Inemisebenzi yokubulala ngokuxhumana, ukubulala isisu kanye nokuvimbela ukuncelisa. Ngokuyinhloko ivimbela ukungenisa okujwayelekile koketshezi ngomphumela wokubulala isisu, futhi kwenzeka isimo sokuvimbela ukuncelisa bese kwenzeka ukufa.
2. Ukungena kahle kanye nokuqhuba kahle. Umuthi owuketshezi unokungena okunamandla ezitshalweni, futhi ungangena futhi kusukela ezimpandeni kuya eziqwini nasemaqabungeni, okunomphumela omuhle wokuvikela amaqabunga amasha kanye nezicubu ezintsha zezitshalo, futhi kungalawula ngempumelelo izinambuzane ezingxenyeni ezahlukene zezitshalo.
3. Ukuqala okusheshayo nokulawula izingozi. Izinambuzane ezihlabayo ziyayeka ukumunca nokudla zingakapheli ihora elingu-0.5 kuya kweli-1 ngemva kokuphefumula ujusi wesitshalo oqukethe i-flonicamid, futhi akukho ndle ezovela ngasikhathi sinye.
4. Isikhathi sokusebenza side. Izinambuzane zaqala ukufa ezinsukwini ezimbili kuya kwezingu-3 ngemva kokufutha, okubonisa umphumela osebenza ngokushesha kancane, kodwa umphumela ohlala isikhathi eside wawufinyelela ezinsukwini ezingu-14, okwakungcono kuneminye imikhiqizo ye-nicotinic.
5. Ukuphepha okuhle. Lo mkhiqizo awunawo umthelela ezilwaneni zasemanzini nasezitshalweni. Uphephile ezitshalweni ngemithamo enconywayo, awunabo ubuthi be-phytotoxic. Unobungane ezinambuzaneni ezizuzisayo nasezitheni zemvelo, futhi uphephile ezinyosini. Ufaneleka kakhulu ukusetshenziswa ezindaweni zokugcina impova.
