Noneho ko tuvuze ku gisekuru cya gatatu nicotinic insecticide dinotefuran, reka tubanze dushyire mubikorwa ibyonnyi byica nicotinic.
Igisekuru cya mbere cyibicuruzwa bya nikotine: imidacloprid, nitenpyram, acetamiprid, thiacloprid.Hagati nyamukuru ni 2-chloro-5-chloromethylpyridine, iri mu itsinda rya chloropyridyl.
Igisekuru cya kabiri nikotine ibicuruzwa: thiamethoxam), umwenda.Hagati nyamukuru ni 2-chloro-5-chloromethylthiazole, iri mu itsinda rya chlorothiazolyl.
Igisekuru cya gatatu cyibicuruzwa bya nikotine: dinotefuran, itsinda rya tetrahydrofuran risimbuza itsinda rya chloro, kandi ntabwo ririmo ibintu bya halogene.
Uburyo bwibikorwa byica udukoko twa nikotine nugukora kuri sisitemu yo kwanduza udukoko, bigatuma bashimishwa bidasanzwe, kumugara no gupfa, kandi bikagira n'ingaruka zo kwica umuntu no kwangiza igifu.Ugereranije na nikotine gakondo, dinotefuran ntabwo irimo ibintu bya halogene, kandi amazi yayo arashobora gukomera, bivuze ko dinotefuran yakirwa byoroshye;n'uburozi bwo mu kanwa bwinzuki ni 1 / 4.6 gusa bya thiamethoxam, uburozi bwo guhura ni kimwe cya kabiri cya thiamethoxam.
Guhera ku ya 30 Kanama 2022, igihugu cyanjye gifite ibyemezo 25 byo kwiyandikisha ku bicuruzwa bya tekiniki ya dinotefuran;164 ibyemezo byo kwiyandikisha kuri dosiye imwe na 111 ibyemezo byo kwiyandikisha bivanze, harimo nudukoko 51 twica udukoko.
Ifishi ya dosiye yanditswemo irimo granules zishonga, imiti ihagarika, ibinyamisogwe bitandukanya amazi, imiti ihagarika imbuto, granules, nibindi, kandi dosiye imwe ni 0.025% -70%.
Ibicuruzwa bivanze birimo pymetrozine, spirotetramat, pyridaben, bifenthrin, nibindi.
01 Dinotefuran + Pymetrozine
Pymetrozine ifite uburyo bwiza bwo gutwara ibintu, kandi ingaruka ya dinotefuran yihuta ni inyungu igaragara yiki gicuruzwa.Byombi bifite uburyo butandukanye bwibikorwa.Iyo ikoreshejwe hamwe, udukoko dupfa vuba kandi ingaruka zimara igihe kirekire.02Dinotefuran + Spirotetramat
Iyi formula ni nemezi ya aphide, thrips, nisazi zera.Mumyaka yashize, uhereye kumurongo no gukoresha ahantu hatandukanye nibitekerezo byabakoresha, ingaruka ziracyashimishije cyane.
03Dinotefuran + Pyriproxyfen
Pyriproxyfen ni ovicide ikora neza, mugihe dinotefuran ikora gusa kubantu bakuru.Guhuza byombi birashobora kwica amagi yose.Iyi formula ni umufatanyabikorwa wuzuye wa zahabu.
04Dinotefuran + Udukoko twangiza Pyrethroid
Iyi formula irashobora kunoza cyane ingaruka ziterwa nudukoko.Imiti yica udukoko twa pyrethroide ubwayo ni udukoko twinshi twica udukoko.Guhuza byombi birashobora kugabanya umuvuduko wo kurwanya ibiyobyabwenge, kandi birashobora no kuvura inyenzi.Nuburyo bwamamajwe cyane nababikora mumyaka yashize.
Gukemura
Abahuza nyamukuru ba dinotefuran ni tetrahydrofuran-3-methylamine na O-methyl-N-nitroisourea.
Umusaruro wa tetrahydrofuran-3-methylamine wibanze cyane muri Zhejiang, Hubei na Jiangsu, kandi ubushobozi bwo kubyaza umusaruro burahagije kugirango habeho ikoreshwa rya dinotefuran.
Umusaruro wa O-methyl-N-nitroisourea wibanze cyane muri Hebei, Hubei na Jiangsu.Nibintu bikomeye cyane hagati ya dinotefuran kubera inzira iteje akaga muri nitrification.
01Dinotefuran ifite udukoko twinshi twica udukoko hamwe nuburyo bukoreshwa, kuva imiti yica udukoko kugeza imiti yisuku, kuva udukoko duto kugeza udukoko nini, kandi bifite ingaruka nziza zo kugenzura.
02Kuvanga neza, dinotefuran irashobora kuvangwa nudukoko dutandukanye twica udukoko hamwe na fungicide, byoroshye gukoresha;ibibyimbye birakungahaye, kandi birashobora gukorwa mubifumbire ya granule, imiti yo gutera imbuto kugirango yambike imbuto, hamwe noguhagarika gutera.
03Umuceri ukoreshwa mugucunga borers hamwe n ibihingwa hamwe nibiyobyabwenge bibiri byica.Birahenze kandi bizaba amahirwe menshi yisoko ryiterambere rya dinotefuran.
04Icyamamare cyo kwirinda kuguruka, dinotefuran irashobora gushonga byoroshye mumazi, bigatuma ikoreshwa cyane mugukoresha uburyo bunini bwo kwirinda kuguruka.Kwamamara mu gukumira indege bizatanga amahirwe adasanzwe yisoko ryiterambere rya kazoza ka dinotefuran.
05D-enantiomer ya dinotefuran itanga ahanini ibikorwa byica udukoko, mugihe L-enantiomer yangiza cyane ubuki bwubutaliyani.Byizerwa ko hamwe niterambere ryikoranabuhanga ryo kweza, dinotefuran, yangiza ibidukikije cyane, izacamo icyuho cyiterambere.
06Kwibanda ku bihingwa niche, kubera ko inzoka zo mu bwoko bwa leek na tungurusumu bigenda birwanya imiti isanzwe, dinotefuran yitwaye neza mu kurwanya udukoko twangiza, kandi gukoresha dinotefuran mu bihingwa niche bizatanga amasoko mashya n’icyerekezo cyo guteza imbere dinotefuran.
07Gutezimbere neza.Inzitizi nini zigira ingaruka kumikurire ya dinotefuran yamye nigiciro kinini cyibiyobyabwenge byumwimerere hamwe nigiciro kinini cyo gukoresha mugutegura itumanaho.Nyamara, igiciro cya dinotefuran kuri ubu kiri kurwego rwo hasi cyane mumateka.Hamwe no kugabanuka kwibiciro, igipimo cyibiciro-imikorere ya dinotefuran yarushijeho kwigaragaza.Twizera ko kuzamura igipimo cyibikorwa bitanga amahirwe menshi yo gukura kwa dinotefuran.
