Zvino zvatava kutaura nezve chizvarwa chechitatu che nicotinic insecticide dinotefuran, ngatitangei taronga mhando dzemishonga ye nicotinic insecticide.
Chizvarwa chekutanga chezvigadzirwa zvenikotini: imidacloprid, nitenpyram, acetamiprid, thiacloprid. Chinhu chikuru chepakati i2-chloro-5-chloromethylpyridine, iyo iri muboka rechloropyridyl.
Zvigadzirwa zvechikoka zvechizvarwa chechipiri: thiamethoxam), clothianidin. Chinhu chikuru chiri pakati nepakati i2-chloro-5-chloromethylthiazole, iyo iri muboka rechlorothiazolyl.
Chizvarwa chechitatu chezvigadzirwa zve nicotine: dinotefuran, boka re tetrahydrofuran rinotsiva boka re chloro, uye harina halogen elements.
Maitiro ekuuraya zvipembenene nenicotine ndeekushanda panzira yekuparadzira tsinga dzezvipembenene, zvichiita kuti dzifare zvisingawanzoitiki, dziome uye dzife, uye zvakare ine mhedzisiro yekuuraya vanhu vanosangana nenicotine uye chepfu mudumbu. Kana ichienzaniswa nenicotine yechinyakare, dinotefuran haina halogen elements, uye kunyunguduka kwayo mumvura kwakasimba, zvinoreva kuti dinotefuran inonyudzwa nyore nyore; uye chepfu yayo mumuromo kunyuchi inongova 1/4.6 chete yethiamethoxam, chepfu yekubatana nenicotine ihafu yethiamethoxam.
Kubva musi wa30 Nyamavhuvhu, 2022, nyika yangu ine zvitupa zvekunyoresa makumi maviri nemashanu zvezvigadzirwa zvehunyanzvi zve dinotefuran; zvitupa zvekunyoresa zana nemakumi matanhatu nemana zvedosi rimwe chete uye zvitupa zvekunyoresa zana negumi nerimwe zvemusanganiswa, kusanganisira mishonga yekuuraya zvipembenene makumi mashanu nerimwe.
Mafomu emushonga akanyoreswa anosanganisira magranules anonyungudika, ma suspending agents, magranules anonyungudika mumvura, ma suspending seed coating agents, magranules, nezvimwewo, uye huwandu hwemushonga mumwe chete i0.025%-70%.
Mishonga yakasanganiswa inosanganisira pymetrozine, spirotetramat, pyridaben, bifenthrin, nezvimwewo.
01 Dinofuran + Pymetrozine
Pymetrozine ine simba rakanaka kwazvo rekufambisa zvinhu mumuviri, uye simba reDinotefuran rinoshanda nekukurumidza ndiro mukana wekuti chigadzirwa ichi chishande. Zviviri izvi zvine nzira dzakasiyana dzekushanda. Kana zvikashandiswa pamwe chete, zvipembenene zvinofa nekukurumidza uye zvinogara kwenguva yakareba.02Dinotefuran + Spirotetramat
Fomura iyi ndiyo fomura yezvipembenene zvinokambaira, thrips, uye nhunzi chena. Mumakore achangopfuura, kubva mukusimudzirwa nekushandiswa kwenzvimbo dzakasiyana-siyana uye mhinduro dzevashandisi, mhedzisiro yacho ichiri kugutsa zvikuru.
03Dinotefuran + Pyriproxyfen
Pyriproxyfen mushonga we ovicide unoshanda zvakanyanya, nepo dinotefuran inoshanda chete kune vakuru. Musanganiswa weizvi zviviri unogona kuuraya mazai ese. Iyi fomura ishamwari yakanaka kwazvo.
04Mishonga yezvipembenene yeDinotefuran + Pyrethroid
Fomura iyi inogona kuvandudza zvikuru simba rekuuraya zvipembenene. Mishonga yezvipembenene inonzi pyrethroid pachayo mishonga yezvipembenene ine spectrum yakakura. Kusanganiswa kwezviviri izvi kunogona kuderedza mwero wekusakwanisa kurwisa mishonga, uye kunogonawo kurapa flea beetle. Iyi fomura inosimudzirwa zvakanyanya nevagadziri mumakore achangopfuura.
Kugadzirisa mhinduro
Zvinhu zvikuru zviri pakati pe dinotefuran ndi tetrahydrofuran-3-methylamine uye O-methyl-N-nitroisourea.
Kugadzirwa kwe tetrahydrofuran-3-methylamine kwakanyanya kuZhejiang, Hubei neJiangsu, uye kugona kwekugadzira kwakakwana kuti ikwanise kushandiswa kwe dinotefuran.
Kugadzirwa kweO-methyl-N-nitroisourea kunonyanya kuwanikwa muHebei, Hubei neJiangsu. Ndiyo inonyanya kukosha pakati pedinotefuran nekuda kwekuita kwakaipa kunobatanidzwa mukuita nitrification.
01Dinotefuran ine mhando dzakasiyana-siyana dzemishonga inouraya zvipembenene uye inoshandiswa, kubva pamishonga yekuuraya zvipembenene kusvika kumishonga yehutsanana, kubva pazvipembenene zvidiki kusvika kuzvipembenene zvikuru, uye ine simba rakanaka rekudzora zvipembenene.
02Dinotefuran inogona kusanganiswa zvakanaka, uye inogona kusanganiswa nemishonga yakasiyana-siyana yekuuraya zvipembenene nemishonga yefungi, iyo iri nyore kushandisa; mafomura acho akawanda, uye inogona kugadzirwa kuita fertilizer ine granule, seed coating agent yekuisa mbeu, uye suspension agent yekuisa spray.
03Mupunga unoshandiswa kudzora zvipembenene zvinobereka zvirimwa nehove nemushonga mumwe chete uye kuuraya kaviri. Haudhuri zvakanyanya uye uchava mukana mukuru wekukura kwezvirimwa zvedinofuran mune ramangwana.
04Nekuda kwekuzivikanwa kwekudzivirira kubhururuka, dinotefuran inonyungudika nyore nyore mumvura, zvichiita kuti ive yakakodzera kushandiswa kukuru kwekudzivirira kubhururuka. Kufarirwa kwekudzivirira kubhururuka kuchapa mukana usingawanzoonekwi wemusika wekuvandudza dinotefuran mune ramangwana.
05D-enantiomer yedinotefuran inonyanya kuuraya zvipembenene, ukuwo L-enantiomer ine chepfu yakanyanya kunyuchi dzekuItaly. Zvinotendwa kuti nekubudirira kwetekinoroji yekuchenesa, dinotefuran, iyo isingakuvadzi nharaunda, ichabuda mudambudziko rayo rekukura.
06Tichitarisa zvirimwa zvidiki, sezvo honye dzeleek negonye dzegariki dzichiramba dzichirwisa makemikari akajairika, dinotefuran yakashanda zvakanaka mukurwisa zvipembenene zvehonye, uye kushandiswa kwedinotefuran muzvirimwa zvidiki kuchapawo misika mitsva nemirairo yekuvandudza dinotefuran.
07Kuvandudzwa kusingadhuri. Chipingamupinyi chikuru chinokanganisa kukura kwe dinotefuran chagara chiri mutengo wakakwira wemushonga wekutanga uye mutengo wakakwira wekushandisa mushonga wekupedzisira. Zvisinei, mutengo we dinotefuran parizvino uri padanho rakaderera munhoroondo. Nekudzikira kwemutengo, chiyero chemutengo-kushanda kwe dinotefuran chave kuwedzera kuzivikanwa. Tinotenda kuti kuvandudzwa kwechiyero chemutengo-kushanda kunopa mikana yakawanda yekukura kwe dinotefuran mune ramangwana.
