Emakethe yokubulala ukhula emasimini elayisi e-China, i-quinclorac, i-bispyribac-sodium, i-cyhalofop-butyl, i-penoxsulam, i-metamifop, njll. zonke zihole indlela.Kodwa-ke, ngenxa yokusetshenziswa isikhathi eside nokuningi kwale mikhiqizo, inkinga yokungazweli emishanguzweni iye yanda, futhi nokulahlekelwa izinga lokulawula uma imikhiqizo ehamba phambili yanda.Imakethe idinga ezinye izindlela ezintsha.

Kulo nyaka, ngaphansi kwethonya lezici ezingezinhle ezifana nezinga lokushisa eliphezulu nesomiso, ukuvalwa kahle uphawu, ukumelana okungathi sína, i-morphology yotshani obuyinkimbinkimbi, notshani obudala kakhulu, i-triadimefon yagqama, yamelana novivinyo olunzima lwemakethe, futhi yazuza ukwanda okukhulu kwemakethe. ukwabelana.

Emakethe yezibulala-zinambuzane emhlabeni wonke ngo-2020, izibulala-zinambuzane zelayisi zizobalelwa cishe i-10%, okuyenza ibe imakethe yesihlanu enkulu yezibulala-zinambuzane ngemuva kwezithelo nemifino, ubhontshisi wesoya, okusanhlamvu kanye nommbila.Phakathi kwazo, inani lokuthengiswa kwemithi yokubulala ukhula emasimini elayisi lalingamaRandi ayizigidi eziyizinkulungwane ezingu-2.479, libekwe kuqala phakathi kwezigaba ezintathu ezinkulu zezibulala-zinambuzane elayisi.

Ngokusho kwesibikezelo sikaPhillips McDougall, ukuthengiswa komhlaba wonke kwezibulala-zinambuzane zerayisi kuzofinyelela ku-6.799 billion US dollars ngo-2024, ngesilinganiso sokukhula sonyaka esiyi-2.2% kusukela ngo-2019 kuya ku-2024. amabhiliyoni amadola aseMelika, anesilinganiso sokukhula sonyaka esihlanganisiwe esingu-1.9% ukusuka ngo-2019 kuya ku-2024.

Ngenxa yokusetshenziswa isikhathi eside, okukhulu kanye nokukodwa kwemihlaba yokubulala ukhula, inkinga yokumelana nezibulala-khula isiphenduke inselele enkulu emhlabeni wonke.Ukhula manje selukwazi ukumelana nezinhlobo ezine zemikhiqizo (EPSPS inhibitors, ALS inhibitors, ACCase inhibitors, PS Ⅱ inhibitors), ikakhulukazi i-ALS inhibitor herbicides (Iqembu B).Kodwa-ke, ukumelana kwe-HPPD inhibitor herbicides (iqembu le-F2) kwakhula kancane, futhi ingozi yokumelana yayiphansi, ngakho-ke bekufanele kugxilwe ekuthuthukisweni nasekukhuthazeni.

Eminyakeni engu-30 edlule, inani lokhula olungazweli emasimini elayisi emhlabeni wonke liye landa ngendlela emangalisayo.Njengamanje, cishe izinhlobo ezingama-80 zokhula lwerayisi ziye zakwazi ukumelana nemithi.

"Ukumelana nezidakamizwa" kuyinkemba esika nhlangothi zombili, engagcini nje ngokuhlupha ukulawulwa okuphumelelayo kwezinambuzane zomhlaba wonke, kodwa futhi ikhuthaza ukuthuthukiswa kwemikhiqizo yezibulala-zinambuzane.I-ejenti yokuvimbela nokulawula ephumelela kakhulu eyenzelwe inkinga evelele yokungazweli emishanguzweni izothola izinzuzo ezinkulu zezohwebo.

Emhlabeni jikelele, imithi yokubulala ukhula esanda kuthuthukiswa emasimini elayisi ihlanganisa i-tetflupyrrolimet, i-dichloroisoxadiazon, i-cyclopyrinil, i-lancotrione sodium (HPPD inhibitor), i-Halauxifen, i-Triadimefon (HPPD inhibitor), i-metcamifen (i-ejenti yokuphepha), i-dimesulfabinale, i-HPPD, i-HPPD njll . Ihlanganisa ama-HPPD inhibitor ambalwa, okubonisa ukuthi ucwaningo nokuthuthukiswa kwemikhiqizo enjalo kusebenza kakhulu.I-Tetflupyrolimet ihlukaniswa njengendlela entsha yokusebenza yi-HRAC (Iqembu28).

I-Triadimefon iyinhlanganisela yesine ye-HPPD inhibitor eyethulwe yi-Qingyuan Nongguan, enqamula umkhawulo wokuthi lolu hlobo lwe-herbicide lungasetshenziswa kuphela ekwelapheni inhlabathi emasimini erayisi.Uwumuthi wokuqala we-HPPD inhibitor osetshenziswa ngokuphephile ekwelapheni kwesiqu nesithombo ngemuva kwezithombo emasimini erayisi ukulawula ukhula oluyigramine emhlabeni.

I-Triadimefon yayinomsebenzi ophezulu ngokumelene notshani be-barnyard notshani berayisi;Ikakhulukazi, inomphumela omuhle kakhulu wokulawula otshanini be-barnyard obungazweli kanye namabele aqinile;Iphephile irayisi futhi ilungele ukutshalwa kabusha kanye nokutshala imbewu ngqo emasimini erayisi.

Kwakungekho ukumelana phakathi kwe-triadimefon kanye nemithi yokubulala ukhula evame ukusetshenziswa emasimini elayisi, njenge-cyhalofop-butyl, i-penoxsulam ne-quinclorac;Ingakwazi ukulawula ngempumelelo ukhula lwe-barnyardgrass olumelana ne-ALS inhibitors kanye ne-ACCase inhibitors emasimini erayisi, kanye nezinhlamvu ze-euphorbia ezimelana ne-ACCAse inhibitors.
