Zvino zvatave kutaura nezve chizvarwa chechitatu nicotinic insecticide dinotefuran, ngatitangei taronga kurongeka kwenicotinic insecticides.
Chizvarwa chekutanga chenicotine zvigadzirwa: imidacloprid, nitenpyram, acetamiprid, thiacloprid.Iyo huru yepakati ndeye 2-chloro-5-chloromethylpyridine, inova yeboka re chloropyridyl.
Zvigadzirwa zvechikakananda zvechizvarwa chechipiri: thiamethoxam), clothianidin.Iyo huru yepakati ndeye 2-chloro-5-chloromethylthiazole, inova yeboka re chlorothiazolyl.
Chizvarwa chechitatu chezvigadzirwa zve nicotine: dinotefuran, boka re tetrahydrofuran rinotsiva boka re chloro, uye harina zvinhu zvehalogen.
Iyo nzira yeicotine insecticidal action ndeyekuita pane nerve transmission system yezvipembenene, zvichiita kuti vafare zvisingaite, kuoma mitezo uye kufa, uye zvakare ine mhedzisiro yekubata kuuraya uye mudumbu muchetura.Kana ichienzaniswa neyechinyakare nicotines, dinotefuran haina halogen zvinhu, uye kunyungudika kwayo kwemvura kwakasimba, izvo zvinoreva kuti dinotefuran inobatwa nyore nyore;uye huturu hwayo hwemukanwa kunyuchi ingori 1/4.6 yeiyo yethiamethoxam , kubata muchetura ihafu yethiamethoxam.
Kubva Nyamavhuvhu 30, 2022, nyika yangu ine zvitupa makumi maviri neshanu zvekunyoresa zve dinotefuran zvigadzirwa zvehunyanzvi;164 zvitupa zvekunyoreswa kwedosi rimwe chete uye 111 zvitupa zvekunyoresa zvemusanganiswa, kusanganisira makumi mashanu nerimwe emishonga yehutsanana.
Mafomu edosi akanyoreswa anosanganisira soluble granules, suspending agents, water-dispersible granules, akamiswa-mbeu yekuputira mbeu, magranules, nezvimwewo, uye imwe dosage yemukati i0.025% -70%.
Zvigadzirwa zvakasanganiswa zvinosanganisira pymetrozine, spirotetramat, pyridaben, bifenthrin, nezvimwe.
01 Dinotefuran + Pymetrozine
Pymetrozine ine yakanaka kwazvo systemic conduction mhedzisiro, uye kukurumidza-kuita kwe dinotefuran ndiyo mukana uri pachena wechigadzirwa ichi.Izvo zviviri zvine nzira dzakasiyana dzekuita.Kana yakashandiswa pamwe chete, zvipembenene zvinofa nokukurumidza uye mugumisiro unogara kwenguva refu.02Dinotefuran + Spirotetramat
Iyi fomula ndiyo inemesis formula yeaphid, thrips, uye whiteflies.Mumakore achangopfuura, kubva mukusimudzirwa uye kushandiswa kwenzvimbo dzakasiyana siyana uye mhinduro yemushandisi, mhedzisiro yacho ichiri kugutsa.
03Dinotefuran + Pyriproxyfen
Pyriproxyfen inonzi ovicide yakakwirira-inoshanda, nepo dinotefuran inoshanda kune vanhu vakuru chete.Kusanganiswa kwezviviri izvi kunogona kuuraya mazai ose.Iyi fomula ndeyechokwadi yegoridhe shamwari.
04Dinotefuran + Pyrethroid Insecticides
Iyi fomula inogona kuvandudza zvakanyanya insecticidal effect.Mishonga yepyrethroid pachayo mishonga inouraya zvipembenene.Kusanganiswa kwezviviri izvi kunogona kuderedza chiyero chekuramba kwemishonga, uye kunogonawo kurapa flea beetle.Iyo fomula yakasimudzirwa zvakanyanya nevagadziri mumakore achangopfuura.
Gadzirisa sarudzo
Iwo makuru epakati e dinotefuran ari tetrahydrofuran-3-methylamine uye O-methyl-N-nitroisourea.
Kugadzirwa kwe tetrahydrofuran-3-methylamine inonyanya kuiswa muZhejiang, Hubei neJiangsu, uye simba rekugadzira rinokwana kusangana nekushandiswa kwe dinotefuran.
Kugadzirwa kweO-methyl-N-nitroisourea kunonyanya kuiswa muHebei, Hubei uye Jiangsu.Ndiyo inonyanya kukosha yepakati ye dinotefuran nekuda kweiyo ine njodzi maitiro anosanganisirwa mu nitrification.
01Dinotefuran ine hupamhi hwezvipembenene uye huwandu hwekushandisa, kubva kune mishonga yezvipembenene kusvika kune mishonga yehutsanana, kubva kune zvipembenene zviduku kusvika kune zvipembenene zvikuru, uye ine simba rakanaka rekutonga.
02Kusanganiswa kwakanaka, dinotefuran inogona kusanganiswa nemhando dzakasiyana dzezvipembenene uye fungicides, zviri nyore kushandisa;magadzirirwo acho akapfuma, uye anogona kugadzirwa kuita granule fetiraiza, seed coating agent yekupfekedza mbeu, uye suspension agent yekupfapfaidza.
03Mupunga unoshandiswa kudzora zvibhorani nemaplanthopper nemushonga mumwe chete nekuuraya kaviri.Iyo inodhura-inoshanda uye ichave yakakura musika mukana wekukura mune ramangwana re dinotefuran.
04Kuzivikanwa kwekudzivirira kubhururuka, dinotefuran inonyungudika nyore nyore mumvura, zvichiita kuti ive yakakodzera kushandiswa kwakakura kwekudzivirira kubhururuka.Kuzivikanwa kwekudzivirira kubhururuka kunopa mukana usingawanzo musika wekuvandudza mune ramangwana re dinotefuran.
05D-enantiomer ye dinotefuran inonyanya kupa basa rekuuraya zvipembenene, ukuwo L-enantiomer ine muchetura zvakanyanya kunyuchi dzekuItaly.Zvinotendwa kuti nekubudirira kwe tekinoroji yekuchenesa, dinotefuran, iyo inonyanya kushamwaridzana nenharaunda, ichapwanya nepakati yayo yekuvandudza bhodhoro.
06Tichitarisa pane zvirimwa zve niche, sezvo honye dze leek negonye dzegariki dzichinyanya kushingirira kumakemikari akajairika, dinotefuran yaita zvakanaka mukudzora tupukanana, uye kushandiswa kwe dinotefuran muzvirimwa zve niche kuchapawo misika mitsva negwara rekusimudzira dinotefuran .
07Kuvandudza kunobatsira.Chipingamupinyi chikuru chinokanganisa kukura kwe dinotefuran yakagara iri mutengo wepamusoro wemushonga wepakutanga uye mutengo wepamusoro wekushandisa wegadziriro yekugadzirisa.Zvisinei, mutengo we dinotefuran parizvino uri padanho rakaderera munhoroondo.Nekuderera kwemutengo, chiyero chemutengo-chinoita che dinotefuran chave chichiwedzera.Isu tinotenda kuti kuvandudzwa kwemutengo-kuita reshiyo kunopa mikana yakawanda yekukura mune ramangwana re dinotefuran.
