Ngoku ukuba sithetha ngesizukulwana sesithathu se-nicotinic insecticide dinotefuran, masiqale silungise ulwahlulo lwezinambuzane ze-nicotinic.
Isizukulwana sokuqala seemveliso ze-nicotine: imidacloprid, nitenpyram, acetamiprid, thiacloprid.I-intermediate ephambili yi-2-chloro-5-chloromethylpyridine, eyeqela le-chloropyridyl.
Iimveliso ze-nicotine zesizukulwana sesibini: i-thiamethoxam), i-clothianidin.Eyona nto iphakathi yi-2-chloro-5-chloromethylthiazole, eyeqela le-chlorothiazolyl.
Isizukulwana sesithathu seemveliso ze-nicotine: i-dinotefuran, iqela le-tetrahydrofuran lithatha indawo yeqela le-chloro, kwaye aliqukethe izinto ze-halogen.
Indlela yokwenza i-nicotine insecticidal action kukusebenza kwi-nerve transmission system yezinambuzane, ezenza zibe nemincili ngokungaqhelekanga, zikhubazeke kwaye zife, kwaye zineziphumo zokubulala ukudibana kunye netyhefu yesisu.Xa kuthelekiswa ne-nicotines yendabuko, i-dinotefuran ayinayo izakhi ze-halogen, kwaye ukunyibilika kwayo kwamanzi kunamandla, oku kuthetha ukuba i-dinotefuran ifumaneka ngokulula;kunye netyhefu yomlomo kwiinyosi yi-1/4.6 kuphela ye-thiamethoxam, i-toxicity yoqhagamshelwano yisiqingatha se-thiamethoxam.
Ukususela ngo-Agasti 30, 2022, ilizwe lam linezatifikethi zokubhalisa ze-25 kwiimveliso zobugcisa ze-dinotefuran;Izatifikethi zobhaliso ezili-164 zeedosi enye kunye nezatifikethi zobhaliso ezili-111 zemixube, kubandakanywa nezibulali-zinambuzane ezingama-51 zococeko.
Iifom zedosi ebhalisiweyo zibandakanya iigranule ezinyibilikayo, ii-agent ezixhomayo, iigranule ezisasazwa ngamanzi, ii-agent zokugquma imbewu ezixhonyiweyo, iigranules, njl. njl., kunye nomxholo wedosi enye yi-0.025% -70%.
Iimveliso ezixubileyo ziquka i-pymetrozine, i-spirotetramat, i-pyridaben, i-bifenthrin, njl.
01 Dinotefuran + Pymetrozine
I-Pymetrozine inefuthe elihle kakhulu le-systemic conduction, kwaye i-dinotefuran i-access-acting effect yinzuzo ebonakalayo yale mveliso.Ezi zimbini zineendlela ezahlukeneyo zokwenza.Xa zisetyenziswa kunye, izinambuzane zifa ngokukhawuleza kwaye umphumo uhlala ixesha elide.02Dinotefuran + Spirotetramat
Le fomula yifomula ye-nemesis yentwala, ithrips, kunye neempukane ezimhlophe.Kwiminyaka yakutshanje, ukusuka ekukhuthazeni nasekusetyenzisweni kweendawo ezahlukeneyo kunye nengxelo yomsebenzisi, umphumo usanelisayo kakhulu.
03I-Dinotefuran + Pyriproxyfen
I-Pyriproxyfen i-ovicide ephezulu, ngelixa i-dinotefuran isebenza kuphela kubantu abadala.Ukudityaniswa kwezi zimbini kungawabulala onke amaqanda.Le fomula liqabane legolide ngokupheleleyo.
04Dinotefuran + Pyrethroid Insecticides
Le fomula inokuphucula kakhulu umphumo we-insecticidal.Izitshabalalisi zepyrethroid ngokwazo zizibulali-zinambuzane ezibanzi.Ukudityaniswa kwezi zimbini kunokunciphisa izinga lokuxhathisa kumachiza, kwaye kunokunyanga iintakumba.Yifomula ekhuthazwa ngokubanzi ngabavelisi kwiminyaka yakutshanje.
Sombulula isisombululo
Amaziko aphambili e-dinotefuran yi-tetrahydrofuran-3-methylamine kunye ne-O-methyl-N-nitroisourea.
Ukuveliswa kwe-tetrahydrofuran-3-methylamine kugxininiswe kakhulu eZhejiang, eHubei naseJiangsu, kwaye amandla okuvelisa anele ukuhlangabezana nokusetyenziswa kwe-dinotefuran.
Ukuveliswa kwe-O-methyl-N-nitroisourea kugxininiswe kakhulu eHebei, eHubei naseJiangsu.Yeyona nto ibalulekileyo phakathi kwe-dinotefuran ngenxa yenkqubo eyingozi ebandakanyekayo kwi-nitrification.
01I-Dinotefuran ine-spectrum ebanzi ye-insecticidal kunye ne-application range, ukusuka kwi-pesticides ukuya kwiziyobisi ezicocekileyo, ukusuka kwiinambuzane ezincinci ukuya kwizinambuzane ezinkulu, kwaye zinefuthe elihle lokulawula.
02Ukuxuba okulungileyo, i-dinotefuran inokuxutywa kunye neentlobo zezinambuzane kunye nefungicides, ekulungele ukuyisebenzisa;Imixube ityebile, kwaye inokwenziwa kwisichumiso segranule, iarhente yokugquma imbewu yokunxitywa kwembewu, kunye nearhente yokunqunyanyiswa ukutshiza.
03Irayisi isetyenziselwa ukulawula iibhore kunye neplanthoppers ngechiza elinye kunye nokubulala kabini.Iyabiza kwaye iya kuba lithuba lemarike elikhulu lokukhula kwekamva le-dinotefuran.
04Ukuthandwa kokuthintela ukubhabha, i-dinotefuran iyanyibilika ngokulula emanzini, okwenza ukuba ifaneleke ngakumbi kusetyenziso olukhulu lokuthintela ukubhabha.Ukuthandwa kokuthintela ukubhabha kuya kunika ithuba elinqabileyo lemarike yophuhliso lwexesha elizayo lwe-dinotefuran.
05I-D-enantiomer ye-dinotefuran ibonelela kakhulu ngomsebenzi wokubulala izinambuzane, ngelixa i-L-enantiomer inetyhefu kakhulu kwiinyosi zase-Italiya.Kukholelwa ukuba ngokuphumelela kwetekhnoloji yokucoca, i-dinotefuran, ehambelana nokusingqongileyo, iya kuqhekeza ibhotile yayo yophuhliso.
06Ukugxininisa kwizityalo ze-niche, njengoko i-leek maggots kunye ne-garlic maggots zixhatshazwa ngakumbi kwiikhemikhali eziqhelekileyo, i-dinotefuran iqhube kakuhle ekulawuleni izinambuzane ze-maggot, kwaye ukusetyenziswa kwe-dinotefuran kwizityalo ze-niche kuya kunika iimarike ezintsha kunye nezikhokelo zokuphuhliswa kwe-dinotefuran .
07Uphuculo olungabizi kakhulu.Owona mqobo mkhulu ochaphazela ukukhula kwe-dinotefuran ibisoloko ilixabiso eliphezulu lechiza lokuqala kunye nexabiso eliphezulu lesicelo solungiselelo lwesiphelo.Nangona kunjalo, ixabiso le-dinotefuran okwangoku lisezantsi kwinqanaba kwimbali.Ngokuhla kwexabiso, umlinganiselo wexabiso-ukusebenza kwe-dinotefuran uye wabonakala ngakumbi.Sikholelwa ukuba ukuphuculwa komlinganiselo wexabiso-ukusebenza kunika amathuba amaninzi okukhula kwexesha elizayo le-dinotefuran.
