Umuthi ophephile wensimu yerayisi i-cyhalofop-butyl - kulindeleke ukuthi ukhombise amandla awo njengesifutho sokulawula impukane

I-Cyhalofop-butyl isibulala-magciwane esihleliwe esakhiwe yi-Dow AgroSciences, eyethulwa e-Asia ngo-1995. I-Cyhalofop-butyl inokuphepha okuphezulu nomthelela omuhle wokulawula, futhi ithandwa kakhulu yimakethe kusukela yethulwa. Njengamanje, imakethe ye-Cyhalofop-butyl isakazeka kuzo zonke izindawo zomhlaba ezitshala irayisi, kuhlanganise ne-Japan, i-China, i-United States, i-Greece, i-Spain, i-France, i-Italy, i-Portugal ne-Australia. Ezweni lami, i-Cyhalofop-butyl isiphenduke i-ejenti yokulawula utshani obufana ne-barnyardgrass kanye ne-stephenia emasimini e-paddy.

Isingeniso somkhiqizo

Umkhiqizo wezobuchwepheshe we-Cyhalofop-butyl uyikristale emhlophe eqinile, encibilika kuzincibilikisi eziningi eziphilayo, engancibiliki emanzini, ifomula yawo yamangqamuzana ithi C20H20FNO4, inombolo yokubhalisa ye-CAS: 122008-85-9

Indlela yokwenza

I-Cyhalofop-butyl iyi-systemic conductive herbicide. Ngemva kokumuncwa amaqabunga nezigxobo zamaqabunga ezitshalo, idlula ku-phloem futhi inqwabelana endaweni yezitshalo, lapho ivimbela i-acetyl-CoA carboxylase (ACCase) futhi ihlanganise ama-fatty acids. Yeka, amangqamuzana awakwazi ukukhula futhi ahlukanise ngokujwayelekile, uhlelo lwe-membrane nezinye izakhiwo eziqukethe i-lipid ziyabhujiswa, futhi ekugcineni isitshalo siyafa.

Lawula into

I-Cyhalofop-butyl isetshenziswa kakhulu emasimini ezithombo zelayisi, izimbewu eziqondile, kanye nezinsimu zokutshala kabusha, futhi ingakwazi ukulawula nokulawula i-Qianjinzi, i-kanmai, utshani obuncane, i-crabgrass, i-foxtail, i-bran millet, i-heart leaf millet, i-pennisetum, ummbila, ne-tendon yenkomo. Utshani nolunye ukhula lwe-gramineous, buphinde bube nomthelela othile wokulawula utshani obuncane be-barnyard, futhi bungakwazi ukulawula ngempumelelo ukhula olumelana ne-quinclorac, sulfonylurea kanye ne-amide herbicides.

Izinzuzo zomkhiqizo

1. Ukusebenza okuphezulu kokubulala ukhula

I-Cyhalofop-butyl ibonise umsebenzi wokubulala ukhula ongenakuqhathaniswa nezinye izibulala-zinambuzane ku-D. chinensis ngaphambi kwesiteji samaqabunga ama-4 emasimini erayisi.

2. Uhlu olubanzi lohlelo lokusebenza

I-cyhalofop-butyl ingasetshenziswa hhayi kuphela emasimini okutshala irayisi, kodwa nasezindaweni ezihlwanyela ngokuqondile irayisi nasemasimini ezithombo.

3. Ukuzivumelanisa nezimo okuqinile

I-Cyhalofop-butyl ingahlanganiswa ne-penoxsulam, i-quinclorac, i-fenoxaprop-ethyl, i-oxaziclozone, njll., engagcini nje ngokunweba i-spectrum ye-herbicidal, kodwa futhi ibambezela ukuvela kokumelana.

4. Ukuvikeleka okuphezulu

I-Cyhalofop-butyl inokukhetha okuhle kakhulu kwelayisi, iphephile elayisini, yonakala ngokushesha enhlabathini nasemanzini e-paddy ajwayelekile, futhi iphephile ezitshalweni ezilandelayo.

Ukulindelwe kwemakethe

Ilayisi liyisilimo sokudla esibaluleke kakhulu emhlabeni. Ngokunwetshwa kwendawo yokutshala okuqondile yerayisi kanye nokwanda kokumelana nokhula lotshani, isidingo semakethe se-cyhalofop-butyl njengomuthi osebenzayo nophephile wokubulala ukhula emasimini elayisi sikhula njalo. Njengamanje, indawo okwenzeka kuyo kanye nokulimala kokhula olufana ne-Dwarfiaceae kanye ne-barnyardgrass emasimini elayisi ezweni lami kuyakhula, futhi ukumelana ne-sulfonylurea kanye ne-amide herbicides kuya ngokuya kuba kubi kakhulu. Kulindeleke ukuthi isidingo se-cyhalofop-butyl sisazokhuphuka eminyakeni embalwa ezayo. Futhi ngenxa yenkinga yokumelana, umthamo owodwa we-cyhalofop-fop uzothambekela ekuthuthukisweni ngokuqukethwe okuphezulu (30% -60%), futhi imikhiqizo eyinhlanganisela enezinye izibulala-zinambuzane nayo izokhula. Ngesikhathi esifanayo, ngokwandiswa kwesikali sokukhiqiza sefekthri kanye nokuthuthukiswa kwemishini yenqubo, amandla emakethe ye-cyhalofop-butyl kanye nemikhiqizo equkethe i-cyhalofop-butyl izokhula futhi ukuncintisana kuzoshuba kakhulu. Ngaphezu kwalokho, ngokuthandwa kobuchwepheshe bokufafaza okulwa nokundiza, i-cyhalofop-ester ilungele ukusetshenziswa njengezinhlobonhlobo zokufafaza okulwa nokundiza, futhi uhlelo lokusebenza lobuchwepheshe besikhathi esizayo nalo lufanele ukubhekelwa phambili.
