Izinambuzane ezitshabalalisayo zezolimo zibonwa njengenye yamaqela ebhayoloji ekunzima ukuwalawula ehlabathini.Phakathi kwazo, ezona zitshabalalisi zixhaphake kakhulu zizigcawu kunye namantshontsho enyongo, anamandla okutshabalalisa izityalo ezinje ngemithi yeziqhamo, imifuno kunye neentyatyambo.Inani kunye neentengiso ze-acaricides zezolimo ezisetyenziselwa ukulawula izilwanyana ezidliwayo zesibini kuphela kwiLepidoptera kunye neHomoptera phakathi kwezitshabalalisi zezolimo kunye ne-acaricides.Nangona kunjalo, kwiminyaka yakutshanje, ngenxa yokusetyenziswa rhoqo kwe-acaricides kunye nokusetyenziswa ngokungafanelekanga kwe-artificial Isizathu kukuba idigri ezahlukeneyo zokuchasana zibonisiwe, kwaye sele kusondele ukuphuhlisa i-acaricides entsha ephezulu kunye nezakhiwo ezinoveli kunye neendlela ezizodwa zokwenza.
Eli nqaku liza kukwazisa uhlobo olutsha lwe-benzoylacetonitrile acaricide - fenflunomide.Imveliso yaphuhliswa yi-Otsuka Chemical Co., Ltd. yaseJapan kwaye yasungulwa okokuqala ngqa ngo-2017. Isetyenziselwa kakhulu ukulawula izifo zezityalo kwizityalo ezifana nemithi yeziqhamo, imifuno kunye nemithi yeti, ngakumbi kwizinambuzane ezitshabalalisayo. baye bahlakulela ukuxhathisa.
Ubume obusisiseko
Igama lesiNgesi eliqhelekileyo: Cyflumetofen;Inombolo yeCAS: 400882-07-7;Ifomula yemolekyuli: C24H24F3NO4;Ubunzima bemolekyuli: 447.4;Igama leKhemikhali: 2-methoxyethyl- (R, S) -2- (4-tert. Butylphenyl) -2-cyano-3-oxo-3- (α, α, α-trifluoro-o-tolyl);Ifomula yolwakhiwo njengoko kubonisiwe ngezantsi.
I-Butflufenafen yi-acaricide ebulala isisu engenazo iimpawu zenkqubo, kwaye indlela yayo ephambili yokusebenza kukuthintela ukuphefumla kwe-mitochondrial ye-mites.Ngokusebenzisa i-de-esterification kwi-vivo, isakhiwo se-hydroxyl senziwe, esiphazamisa kwaye sinqande i-mitochondrial protein complex II, ithintela ukudluliselwa kwe-electron (i-hydrogen), itshabalalise ukuphendula kwe-phosphorylation, kwaye ibangele ukukhubazeka nokufa kwamangolwane.
Iimpawu zesenzo se-cyflumetofen
(1) Umsebenzi ophezulu kunye nedosi ephantsi.Kuphela ishumi elinesibini leegrem kwimu yomhlaba ngamnye esetyenziswayo, i-low-carbon, ikhuselekile kwaye ihambelana nokusingqongileyo;
(2) I-spectrum ebanzi.Isebenza kuzo zonke iintlobo zezinambuzane;
(3) Ukhetha kakhulu.Kuphela inesiphumo esikhethekileyo sokubulala kwiingolwane eziyingozi, kwaye ineempembelelo ezincinci ezingalunganga kwizinto ezingajoliswanga kunye namangolwane;
(4) Ukuqonda ngokubanzi.Ingasetyenziselwa ngaphandle kunye nezityalo ezikhuselweyo ze-horticultural ukulawula ama-mites kwizigaba ezahlukeneyo zokukhula kwamaqanda, imibungu, i-nymphs kunye nabantu abadala, kwaye inokusetyenziswa ngokubambisana ne-biological control technology;
(5) Zombini iziphumo ezikhawulezayo nezihlala zihleli.Kwiiyure ezingama-4, iimite ezinobungozi ziyakuyeka ukutya, kwaye izinambuzane ziya kukhubazeka kwiiyure ezili-12, kwaye umphumo okhawulezayo ulungile;kwaye inesiphumo esihlala ixesha elide, kwaye isicelo esinye sinokulawula ixesha elide;
(6) Akukho lula ukuphuhlisa ukunganyangeki ngamachiza.Inomsebenzi okhethekileyo wokusebenza, akukho ukuchasana ne-acaricides esele ikhona, kwaye akukho lula ukuba amangolwane aphuhlise ukuxhathisa kuyo;
7Sisixhobo esilungileyo solawulo lokuxhathisa.
IiMarike zeHlabathi kunye noBhaliso
Kwi-2007, i-fenflufen yaqala ukubhaliswa kwaye yathengiswa eJapan.Ngoku i-bufenflunom ibhalisiwe kwaye ithengiswe eJapan, eBrazil, eUnited States, eChina, eMzantsi Korea, kwi-European Union nakwamanye amazwe.Iintengiso ikakhulu ziseBrazil, eUnited States, eJapan, njl.njl., zibalelwa malunga ne-70% yeentengiso zehlabathi;olona setyenziso luphambili kulawulo lweengolwane kwimithi yeziqhamo efana ne-citrus kunye nama-apile, ezibalelwa ngaphezulu kwe-80% yentengiso yehlabathi.
I-EU: Idweliswe kwi-EU Annex 1 kwi-2010 kwaye ibhaliswe ngokusemthethweni kwi-2013, iyasebenza kude kube yi-31 May 2023.
EUnited States: Ibhaliswe ngokusemthethweni kunye ne-EPA ngo-2014, kwaye ivunywe yiCalifornia ngo-2015. Kwiminatha yemithi (iintlobo zezityalo 14-12), amapere (amacandelo ezityalo 11-10), i-citrus (iintlobo zezityalo 10-10), iidiliya, amaqunube , iitumato kunye nezityalo ze-landscape.
EKhanada: Ivunyiwe ukuba ibhaliswe yi-Arhente yoLawulo lweZitshabalalisi yaseKhanada (PMRA) ngo-2014.
EBrazil: Yaqinisekiswa ngo-2013. Ngokombuzo wewebhusayithi, ukuza kuthi ga ngoku, ubukhulu becala idosi enye ye-200g/L SC, esetyenziswa kakhulu kwi-citrus ukulawula amangolwane amfusa aneendevu ezimfutshane, ama-apile okulawula ama-apile spider mites, kunye ikofu yokulawula amangolwane aneendevu ezimfusa-bomvu, amantshontsho amancinci, njl.
I-China: Ngokutsho kwe-China Pesticide Information Network, kukho ukubhaliswa kabini kwe-fenflufenac e-China.Enye idosi enye ye-200g / L SC, ebanjwe yi-FMC.amangolwane.Olunye lubhaliso lobugcisa olubanjwe yiJapan Ouite Agricultural Technology Co., Ltd.
EOstreliya: NgoDisemba 2021, i-Australian Pesticide and Veterinary Medicines Administration (APVMA) ibhengeze imvume kunye nokubhaliswa kwe-200 g/L buflufenacil suspension ukusuka ngoDisemba 14, 2021 ukuya kuJanuwari 11, 2022. Ingasetyenziselwa ukulawula iintlobo zemites kwi i-pome, i-almond, i-citrus, idiliya, iziqhamo kunye nemifuno, i-strawberry kunye nezityalo zokuhombisa, kwaye ingasetyenziselwa izicelo zokukhusela kwi-strawberries, iitumato kunye nezityalo zokuhombisa.
