Cyhalofop-butyl ndi ndondomeko ya herbicide yopangidwa ndi Dow AgroSciences, yomwe inayambika ku Asia mu 1995. Cyhalofop-butyl ili ndi chitetezo chapamwamba komanso mphamvu yabwino yolamulira, ndipo yakhala ikukondedwa kwambiri ndi msika kuyambira pamene idakhazikitsidwa. Pakalipano, msika wa Cyhalofop-butyl umafalikira kumadera onse omwe amalima mpunga padziko lonse lapansi, kuphatikizapo Japan, China, United States, Greece, Spain, France, Italy, Portugal ndi Australia. M'dziko langa, Cyhalofop-butyl yakhala yoyang'anira udzu wa udzu monga barnyardgrass ndi stephenia m'minda ya paddy.
Chiyambi cha malonda
Cyhalofop-butyl technical product ndi white crystalline solid, sungunuka m'madzi ambiri osungunulira, osasungunuka m'madzi, mamolekyu ake ndi C20H20FNO4, nambala yolembetsa ya CAS: 122008-85-9
Njira yochitira
Cyhalofop-butyl ndi systemic conductive herbicide. Ikamwedwa ndi masamba ndi masamba a zomera, imadutsa mu phloem ndikudziunjikira m'dera la meristem la zomera, komwe imalepheretsa acetyl-CoA carboxylase (ACCase) ndikupanga mafuta acids. Imani, maselo sangathe kukula ndikugawaniza bwino, dongosolo la nembanemba ndi zida zina zokhala ndi lipid zimawonongeka, ndipo pamapeto pake mbewuyo imafa.
Control chinthu
Cyhalofop-butyl imagwiritsidwa ntchito makamaka m'minda ya mbande ya mpunga, minda yobzala mbewu mwachindunji, ndi minda yobzala, ndipo imatha kuwongolera ndi kuwongolera Qianjinzi, kanmai, udzu waung'ono, nkhanu, nkhandwe, mapira, mapira amtima, pennisetum, chimanga, ndi tendon ya ng'ombe. Udzu ndi namsongole wina wa gramineous, umakhalanso ndi mphamvu yowongolera pa udzu waung'ono wa barnyardgrass, komanso umatha kuwongolera namsongole womwe umalimbana ndi quinclorac, sulfonylurea ndi amide herbicides.
Ubwino wa mankhwala
1. Kuchuluka kwa herbicides
Cyhalofop-butyl inawonetsa ntchito ya herbicidal yosafanana ndi mankhwala ena ophera tizilombo pa D. chinensis pamaso pa siteji ya masamba 4 m'minda ya mpunga.
2. Ntchito zambiri
Cyhalofop-butyl itha kugwiritsidwa ntchito osati m'minda yothira mpunga wokha, komanso m'minda yobzala mpunga molunjika komanso m'minda ya mbande.
3. Kusinthasintha kwamphamvu
Cyhalofop-butyl imatha kuphatikizidwa ndi penoxsulam, quinclorac, fenoxaprop-ethyl, oxaziclozone, ndi zina zotero, zomwe sizimangowonjezera kuchuluka kwa herbicidal, komanso kuchedwetsa kutuluka kwa kukana.
4. Chitetezo chachikulu
Cyhalofop-butyl imasankha bwino mpunga, ndi yabwino kwa mpunga, imawonongeka mwachangu m'nthaka komanso madzi a paddy, ndipo ndi yabwino ku mbewu zotsatila.
Chiyembekezo cha msika
Mpunga ndi mbewu yofunika kwambiri padziko lonse lapansi. Kukula kwa malo obzala mpunga mwachindunji komanso kukana kwa udzu, kufunikira kwa msika wa cyhalofop-butyl ngati mankhwala ophera udzu wothandiza komanso otetezeka m'minda ya mpunga kukukulirakulira. Pakalipano, malo omwe amapezeka ndi kuwonongeka kwa namsongole monga Dwarfiaceae ndi barnyardgrass m'minda ya mpunga m'dziko langa akuwonjezeka, ndipo kukana kwa sulfonylurea ndi amide herbicides kukukulirakulira. Zikuyembekezeka kuti kufunikira kwa cyhalofop-butyl kudzakwerabe m'zaka zingapo zikubwerazi. Ndipo chifukwa cha vuto la kukana, mlingo umodzi wa cyhalofop-fop umakonda kupangidwa ndi zinthu zambiri (30% -60%), ndipo mankhwala omwe ali ndi mankhwala ophera tizilombo adzawonjezeka. Panthawi imodzimodziyo, ndikukula kwa kukula kwa fakitale ndi kukweza kwa zipangizo zamakono, msika wa cyhalofop-butyl ndi zinthu zomwe zili ndi cyhalofop-butyl zidzakula kwambiri ndipo mpikisano udzakula kwambiri. Kuphatikiza apo, ndi kutchuka kwaukadaulo wopopera mbewu mankhwalawa, cyhalofop-ester ndi yoyenera kugwiritsidwa ntchito ngati kupopera mbewu mankhwalawa mosiyanasiyana, komanso kugwiritsa ntchito ukadaulo wamtsogolo ndikofunikira kuyembekezera.
