Manje njengoba sesikhuluma ngesibulala-zinambuzane se-nicotinic yesizukulwane sesithathu i-dinotefuran, ake siqale silungise ukuhlukaniswa kwezibulala-zinambuzane ze-nicotinic.
Isizukulwane sokuqala semikhiqizo ye-nicotine: imidacloprid, nitenpyram, acetamiprid, thiacloprid.Okumaphakathi okuyinhloko yi-2-chloro-5-chloromethylpyridine, okungokweqembu le-chloropyridyl.
Imikhiqizo ye-nicotine yesizukulwane sesibili: i-thiamethoxam), i-clothianidin.Okumaphakathi okuyinhloko yi-2-chloro-5-chloromethylthiazole, okungokweqembu le-chlorothiazolyl.
Isizukulwane sesithathu semikhiqizo ye-nicotine: i-dinotefuran, iqembu le-tetrahydrofuran lithatha indawo yeqembu le-chloro, futhi aliqukethe izakhi ze-halogen.
Indlela yokwenza i-nicotine insecticidal action iwukuthatha isinyathelo ohlelweni lokudlulisela izinzwa zezinambuzane, okuzenza zijabule ngendlela engavamile, zikhubazeke futhi zife, futhi kunemiphumela yokubulala ukuthintana kanye nobuthi besisu.Uma kuqhathaniswa nama-nicotine endabuko, i-dinotefuran ayinazo izakhi ze-halogen, futhi ukuncibilika kwayo emanzini kunamandla, okusho ukuthi i-dinotefuran imuncwa kalula;futhi ubuthi bayo bomlomo ezinyosini buyi-1/4.6 kuphela yaleyo ye-thiamethoxam, ubuthi bokuxhumana buyingxenye ye-thiamethoxam.
Kusukela ngo-Agasti 30, 2022, izwe lami linezitifiketi zokubhalisa ezingu-25 zemikhiqizo yobuchwepheshe ye-dinotefuran;Izitifiketi zokubhaliswa kwemithamo eyodwa eziyi-164 kanye nezitifiketi zokubhalisa eziyi-111 zezingxube, okuhlanganisa nezibulala-zinambuzane ezingama-51.
Amafomu omthamo obhalisiwe ahlanganisa ama-granules ancibilikayo, ama-ejenti alengayo, ama-granules ahlakazeka emanzini, ama-agent amisiwe ahlanganisa imbewu, ama-granules, njll., kanye nomthamo owodwa okuqukethwe ngu-0.025% -70%.
Imikhiqizo ehlanganisiwe ihlanganisa i-pymetrozine, i-spirotetramat, i-pyridaben, i-bifenthrin, njll.
01 I-Dinotefuran + Pymetrozine
I-Pymetrozine inomphumela omuhle kakhulu we-systemic conduction, futhi umphumela wokusheshisa we-dinotefuran uyinzuzo esobala yalo mkhiqizo.Zombili zinezinqubo ezihlukene zokwenza.Uma zisetshenziswa ndawonye, izinambuzane zifa ngokushesha futhi umphumela uhlala isikhathi eside.02I-Dinotefuran + Spirotetramat
Le fomula iyifomula ye-nemesis yama-aphid, amathrips, nezimpukane ezimhlophe.Eminyakeni yakamuva, kusukela ekuthuthukisweni nasekusetshenzisweni kwezindawo ezihlukahlukene kanye nempendulo yomsebenzisi, umphumela usagculisa kakhulu.
03I-Dinotefuran + Pyriproxyfen
I-Pyriproxyfen iyi-ovicide esebenza kahle kakhulu, kuyilapho i-dinotefuran isebenza kuphela kubantu abadala.Inhlanganisela yalokhu okubili ingabulala wonke amaqanda.Le fomula inguzakwethu osagolide ngokuphelele.
04I-Dinotefuran + Pyrethroid Insecticides
Le fomula ingawuthuthukisa kakhulu umphumela we-insecticidal.Izibulala-zinambuzane ze-pyrethroid ngokwazo ziyi-broad-spectrum ebulala izinambuzane.Inhlanganisela yalokhu kokubili inganciphisa izinga lokungazweli emishanguzweni, futhi ingakwazi nokwelapha ibhungane lezeze.Kuyifomula ekhuthazwa kabanzi abakhiqizi eminyakeni yamuva.
Xazulula isixazululo
Iziphakathi eziyinhloko ze-dinotefuran yi-tetrahydrofuran-3-methylamine ne-O-methyl-N-nitroisourea.
Ukukhiqizwa kwe-tetrahydrofuran-3-methylamine ikakhulukazi kugxile eZhejiang, eHubei naseJiangsu, futhi amandla okukhiqiza anele ukuhlangabezana nokusetshenziswa kwe-dinotefuran.
Ukukhiqizwa kwe-O-methyl-N-nitroisourea kugxile kakhulu eHebei, eHubei naseJiangsu.Iyindawo ephakathi ebaluleke kakhulu ye-dinotefuran ngenxa yenqubo eyingozi ehilelekile ku-nitrification.
01I-Dinotefuran ine-spectrum ebanzi ye-insecticidal kanye nohla lwesicelo, kusukela ezibulala-zinambuzane kuya emithini ehlanzekile, kusukela ezinambuzaneni ezincane kuya ezinambuzaneni ezinkulu, futhi inomphumela omuhle wokulawula.
02Ukuxutshwa okuhle, i-dinotefuran ingaxutshwa nezinhlobonhlobo zama-insecticide nama-fungicides, okulula ukuwasebenzisa;ukwakheka kucebile, futhi kungenziwa kumanyolo we-granule, i-ejenti yokugqoka imbewu yokugqoka imbewu, kanye ne-ejenti yokumiswa ukuze kufafazwe.
03Ilayisi lisetshenziselwa ukulawula ama-borers kanye nezitshalo zezitshalo ngomuthi owodwa kanye nokubulala okubili.Ibiza kakhulu futhi izoba yithuba lemakethe elikhulu lokukhula okuzayo kwe-dinotefuran.
04Ukuthandwa kokuvimbela ukundiza, i-dinotefuran inyibilika kalula emanzini, okwenza ifaneleke kakhulu ukusetshenziswa kwezinga elikhulu lokuvikela ukundiza.Ukwaziwa kokuvikela ukundiza kuzonikeza ithuba lemakethe elingandile lokuthuthukiswa kwesikhathi esizayo kwe-dinotefuran.
05I-D-enantiomer ye-dinotefuran ihlinzeka ngokubulala izinambuzane, kuyilapho i-L-enantiomer iyingozi kakhulu ezinyosini zoju zase-Italy.Kukholakala ukuthi ngokuthuthuka kobuchwepheshe bokuhlanza, i-dinotefuran, ehambisana nemvelo, izodabula ibhodlela layo lokuthuthuka.
06Ngokugxila ezitshalweni ze-niche, njengoba izimpethu ze-leek nezimpethu zikagalikhi zikwazi ukumelana namakhemikhali avamile, i-dinotefuran yenze kahle ekulawuleni izinambuzane zezibungu, futhi ukusetshenziswa kwe-dinotefuran ezitshalweni ze-niche kuzohlinzeka ngezimakethe ezintsha nezikhombisi-ndlela zokuthuthukiswa kwe-dinotefuran .
07Ukuthuthukiswa okungabizi kakhulu.Isithiyo esikhulu esithinta ukukhula kwe-dinotefuran bekulokhu kuyintengo ephezulu yomuthi wangempela kanye nezindleko eziphakeme zokusetshenziswa zokulungiselela ukuphela.Nokho, intengo ye-dinotefuran okwamanje isezingeni eliphansi kakhulu emlandweni.Ngokwehla kwentengo, isilinganiso sokusebenza kwentengo ye-dinotefuran sesigqame kakhulu.Sikholelwa ukuthi ukuthuthukiswa kwesilinganiso sokusebenza kwentengo kunikeza amathuba amaningi okukhula okuzayo kwe-dinotefuran.
