Umchiza wokutshabalalisa ukhula kwintsimi yerayisi ekhuselekileyo icyhalofop-butyl -kulindeleke ukuba ibonise amandla ayo njengesitshizi sokulawula iimpukane

I-Cyhalofop-butyl sisichiza sokhula esicwangcisiweyo esaphuhliswa yi-Dow AgroSciences, eyasungulwa e-Asia ngo-1995. I-Cyhalofop-butyl inokhuseleko oluphezulu kunye nempembelelo yokulawula egqwesileyo, kwaye iye yathandwa kakhulu yimarike ukususela oko yasungulwa. Okwangoku, imarike yeCyhalofop-butyl isasazeka kuyo yonke indawo ekhula irayisi yehlabathi, kuquka iJapan, iChina, iUnited States, iGrisi, iSpain, iFransi, i-Itali, iPortugal ne-Australia. Kwilizwe lam, i-Cyhalofop-butyl iye yaba yi-arhente yokulawula ukhula lwengca olufana ne-barnyardgrass kunye ne-stephenia kumasimi e-paddy.

Intshayelelo yemveliso

Imveliso yobugcisa ye-Cyhalofop-butyl yikristale emhlophe eqinileyo, e-soluble kwi-solvents ezininzi zezinto eziphilayo, ezinganyibiliki emanzini, ifomula yayo ye-molecular yi-C20H20FNO4, inombolo yokubhalisa ye-CAS: 122008-85-9

Indlela yokwenza

I-Cyhalofop-butyl yinkqubo ye-systemic conductive herbicide. Emva kokuba ifunxwe ngamagqabi kunye neesheaths zezityalo, iqhubela phambili kwi-phloem kwaye iqokelele kwindawo ye-meristem yezityalo, apho inqanda i-acetyl-CoA carboxylase (ACCase) kwaye idibanise i-acids enamafutha. Yeka, iiseli azikwazi ukukhula kunye nokwahlula ngokuqhelekileyo, inkqubo ye-membrane kunye nezinye izakhiwo eziqukethe i-lipid zichithwa, kwaye ekugqibeleni isityalo siyafa.

Lawula into

I-Cyhalofop-butyl isetyenziswa kakhulu kumasimi embewu yerayisi, amasimi embewu ngokuthe ngqo, kunye namasimi okutyalwa, kwaye inokulawula kwaye ilawule iQianjinzi, kanmai, ingca encinci yebran, crabgrass, foxtail, bran millet, heart leaf millet, pennisetum, umbona, kunye nethon yenkomo. Ingca kunye nolunye ukhula lwegramineous, ikwanempembelelo ethile yokulawula kwi-barnyardgrass encinci, kwaye inokulawula ngempumelelo ukhula oluxhathisayo kwi-quinclorac, sulfonylurea kunye ne-amide herbicides.

Iinzuzo zemveliso

1. Umsebenzi ophezulu wokutshabalalisa ukhula

I-Cyhalofop-butyl ibonise umsebenzi we-herbicidal ongahambelani nezinye izitshabalalisi kwi-D. chinensis ngaphambi kwesigaba se-4-leaf kumasimi erayisi.

2. Uluhlu olubanzi lwesicelo

I-cyhalofop-butyl ingasetyenziselwa kuphela kwiindawo zokutshala irayisi, kodwa nakwiindawo zokutshala irayisi ngokuthe ngqo kunye namasimi ezithole.

3. Ukuziqhelanisa okuqinileyo

I-Cyhalofop-butyl inokudibaniswa ne-penoxsulam, i-quinclorac, i-fenoxaprop-ethyl, i-oxaziclozone, njl., engagcini nje ukwandisa i-herbicidal spectrum, kodwa ilibazise ukuvela kokumelana.

4. Ukhuseleko oluphezulu

I-Cyhalofop-butyl inokukhethwa okuhle kakhulu kwerayisi, ikhuselekile kwirayisi, ithotywa ngokukhawuleza emhlabeni kunye namanzi aqhelekileyo e-paddy, kwaye ikhuselekile kwizityalo ezilandelayo.

Ulindelo lwemarike

Irayisi sesona sityalo sokutya sibalulekileyo ehlabathini. Ngokwandiswa kwendawo yokuhlwayela ngokuthe ngqo kwerayisi kunye nokwanda kokuchasana kokhula lwengca, imfuno yentengiso ye-cyhalofop-butyl njengeyeza elisebenzayo nelikhuselekileyo lokutshabalalisa ukhula kumasimi erayisi lihlala lisanda. Okwangoku, indawo yesiganeko kunye nomonakalo wokhula olufana ne-Dwarfiaceae kunye ne-barnyardgrass kumasimi erayisi kwilizwe lam iyanda, kwaye ukuchasana ne-sulfonylurea kunye ne-amide herbicides kuya kuba nzima ngakumbi. Kulindeleke ukuba imfuno ye-cyhalofop-butyl isazonyuka kwiminyaka embalwa ezayo. Kwaye ngenxa yengxaki yokumelana, idosi enye ye-cyhalofop-fop iya kuthambekela ekuphuhliseni umxholo ophezulu (30% -60%), kwaye iimveliso ezihlanganisiweyo kunye nezinye izitshabalalisi ziya kwanda. Kwangaxeshanye, kunye nokwandiswa kwesikali somzi mveliso kunye nokuphuculwa kwezixhobo zenkqubo, umthamo wentengiso we-cyhalofop-butyl kunye neemveliso eziqulethe i-cyhalofop-butyl ziya kwanda ngakumbi kwaye ukhuphiswano luya kuba nzulu ngakumbi. Ukongezelela, kunye nokuthandwa kweteknoloji yokutshiza i-anti-flying, i-cyhalofop-ester ifanelekile ukusetyenziswa njengeentlobo ezahlukeneyo zokutshiza i-anti-flying, kunye nesicelo sobugcisa bexesha elizayo sifanele sijonge phambili.
