Izinambuzane zezolimo zibonwa njengenye yeqembu lebhayoloji okunzima ukuzilawula emhlabeni.Phakathi kwazo, izinambuzane ezivame kakhulu izibungu ikakhulukazi izibungu zesicabucabu kanye nezibungu zenyongo, ezinekhono elinamandla lokulimaza izitshalo zomnotho njengezihlahla zezithelo, imifino nezimbali.Inombolo nokuthengiswa kwama-acaricides ezolimo asetshenziselwa ukulawula izibungu ezidla uhlaza kungokwesibili ngemuva kwe-Lepidoptera ne-Homoptera phakathi kwezibulala-zinambuzane zezolimo nama-acaricides.Kodwa-ke, eminyakeni yamuva, ngenxa yokusetshenziswa njalo kwama-acaricides kanye nokusetshenziswa okungafanele kokwenziwa kwesizathu siwukuthi amazinga ahlukene okumelana abonisiwe, futhi sekuseduze ukuthuthukisa ama-acaricides asebenza kahle kakhulu anezakhiwo zamanoveli kanye nezindlela eziyingqayizivele zokwenza.
Lesi sihloko sizokwethula uhlobo olusha lwe-benzoylacetonitrile acaricide - fenflunomide.Lo mkhiqizo wathuthukiswa yi-Otsuka Chemical Co., Ltd. yase-Japan futhi wethulwa okokuqala ngqa ngo-2017. Usetshenziselwa kakhulu ukulawula izibungu ezitshalweni ezifana nezihlahla zezithelo, imifino kanye nezihlahla zetiye, ikakhulukazi izibungu ezihlasela izitshalo. baye bahlakulela ukumelana.
Imvelo eyisisekelo
Igama lesiNgisi elivamile: Cyflumetofen;Inombolo ye-CAS: 400882-07-7;Ifomula yemolekyuli: C24H24F3NO4;Isisindo samangqamuzana: 447.4;Igama lekhemikhali: 2-methoxyethyl-(R,S)-2-(4-tert. Butylphenyl)-2-cyano-3-oxo-3-(α,α,α-trifluoro-o-tolyl);ifomula yesakhiwo njengoba kukhonjisiwe ngezansi.
I-Butflufenafen iyi-acaricide ebulala isisu engenazo izici zesistimu, futhi indlela yayo eyinhloko yokusebenza iwukuvimbela ukuphefumula kwe-mitochondrial yezibungu.Ngokusebenzisa i-de-esterification ku-vivo, kwakheka isakhiwo se-hydroxyl, esiphazamisa futhi sivimbele i-mitochondrial protein complex II, ivimbela ukudluliswa kwe-electron (hydrogen), ibhubhise ukusabela kwe-phosphorylation, futhi ibangele ukukhubazeka nokufa kwezibungu.
Izici zesenzo se-cyflumetofen
(1) Umsebenzi ophezulu kanye nomthamo ophansi.Kusetshenziswa amagremu ayishumi nambili kuphela ku-mu ngayinye yomhlaba, enekhabhoni ephansi, ephephile futhi enobungani nemvelo;
(2) I-spectrum ebanzi.Isebenza kuzo zonke izinhlobo zezibungu zezinambuzane;
(3) Ikhetha kakhulu.Inemiphumela ethile kuphela yokubulala ezibungwini eziyingozi, futhi inomthelela omncane omubi ezilwaneni ezingahlosiwe kanye nezibungu ezidla ezinye;
(4) Ukuqondisisa.Ingasetshenziselwa izitshalo zangaphandle nezivikelekile ze-horticultural ukulawula izibungu ezigabeni ezihlukahlukene zokukhula kwamaqanda, izibungu, ama-nymphs kanye nabantu abadala, futhi ingasetshenziswa ngokuhambisana nobuchwepheshe bokulawula izinto eziphilayo;
(5) Kokubili imiphumela esheshayo nehlala njalo.Kungakapheli amahora angu-4, izibungu eziyingozi zizoyeka ukudla, futhi izibungu zizokhubazeka kungakapheli amahora angu-12, futhi umphumela osheshayo muhle;futhi inomphumela ohlala isikhathi eside, futhi isicelo esisodwa singalawula isikhathi eside;
(6) Akulula ukuthuthukisa ukumelana nezidakamizwa.Inomshini wokusebenza oyingqayizivele, akukho ukumelana ne-acaricide ekhona, futhi akulula ukuthi izibungu zithuthukise ukumelana nazo;
(7) Igaywa ngokushesha futhi ibole emhlabathini nasemanzini, okuphephile ezitshalweni nasezintweni ezingahlosiwe njengezilwane ezincelisayo nezinto eziphila emanzini, izinto eziphilayo ezinenzuzo, kanye nezitha zemvelo.Kuyithuluzi elihle lokuphatha ukumelana.
Izimakethe Zomhlaba Wonke Nokubhaliswa
Ngo-2007, i-fenflufen yabhaliswa okokuqala futhi yathengiswa eJapane.Manje i-bufenflunom isibhalisiwe futhi yathengiswa e-Japan, Brazil, United States, China, South Korea, European Union nakwamanye amazwe.Ukuthengiswa ikakhulukazi eBrazil, e-United States, eJapan, njll., kubalwa cishe u-70% wokuthengiswa komhlaba wonke;ukusetshenziswa okuyinhloko ukulawula izibungu ezihlahleni zezithelo ezifana ne-citrus nama-apula, okubalela ngaphezu kwama-80% okuthengiswa emhlabeni jikelele.
I-EU: Ifakwe ohlwini ku-EU Annex 1 ngo-2010 futhi yabhaliswa ngokusemthethweni ngo-2013, isebenza kuze kube umhla zingama-31 kuMeyi 2023.

I-Canada: Igunyazwe ukubhaliswa yi-Health Canada's Pest Management Agency (PMRA) ngo-2014.
IBrazil: Yagunyazwa ngo-2013. Ngokombuzo wewebhusayithi, kuze kube manje, iwumthamo owodwa ka-200g/L SC, osetshenziswa kakhulu kumawolintshi ukulawula izimbuzane ezinentshebe ezimfishane ezinsomi, ama-apula okulawula izibungu zesicabucabu se-apula, kanye ikhofi ukulawula izimbuzane ezinentshebe emfishane ezibomvu-obomvu, izibungu ezincane ze-claw, njll.
I-China: Ngokusho kwe-China Pesticide Information Network, kukhona ukubhaliswa okubili kwe-fenflufenac e-China.Omunye umthamo owodwa we-200g/L SC, ophethwe yi-FMC.izibungu.Okunye ukubhaliswa kwezobuchwepheshe okuphethwe yi-Japan Ouite Agricultural Technology Co., Ltd.
E-Australia: NgoDisemba 2021, i-Australian Pesticide and Veterinary Medicines Administration (APVMA) yamemezela ukugunyazwa nokubhaliswa kokumiswa kwe-buflufenacil okungu-200 g/L kusukela ngomhla ka-14 Disemba 2021 kuya kuJanuwari 11, 2022. Ingasetshenziswa ukulawula izinhlobo ezihlukahlukene zezibungu i-pome, i-almond, i-citrus, amagilebhisi, izithelo nemifino, ama-strawberry kanye nezitshalo zokuhlobisa, futhi ingasetshenziselwa ukuvikela ama-strawberry, utamatisi kanye nezitshalo zokuhlobisa.
