cyhalofop butyl ester CAS:122008-85-9

Cyhalofop-butyl ester ndi mankhwala ofunikira kwambiri ophera udzu omwe amagwiritsidwa ntchito makamaka pakulima mpunga koma amagwiritsidwanso ntchito m'machitidwe ena a mbewu. Popeza ndi membala wa gulu la aryloxyphenoxypropionate, amadziwika kuti amasankha udzu wa udzu pomwe ndi otetezeka ku mbewu za masamba otambalala, zomwe ndizofunikira kwambiri pamapulogalamu ophatikizana osamalira udzu. Mwanjira, cyhalofop-butyl imagwira ntchito poletsa acetyl-CoA carboxylase (ACCase), enzyme yofunika kwambiri panjira ya mafuta acid biosynthesis m'zomera. Mwa kusokoneza njira iyi ya kagayidwe kachakudya, mankhwala ophera udzu amalepheretsa kukula kwa mitundu ya udzu wovuta, zomwe zimapangitsa kuti afe pomwe amalola mbewu kuti ikule bwino. Kuchita kosankha kumeneku kumachitika chifukwa cha njira zenizeni za biochemical zomwe zimayendetsedwa ndi mankhwala ophera udzu, omwe amapezeka mu udzu koma osati mu mbewu za masamba otambalala zomwe nthawi zambiri zimakhala nazo. Kugwiritsa ntchito cyhalofop-butyl kumatha kuchitika kudzera mu kupopera pansi ndi mlengalenga, nthawi zambiri mogwirizana ndi njira zina zosamalira udzu. Kapangidwe kake kamatanthauza kuti kamayamwa kudzera m'masamba ndi mizu, zomwe zimathandiza kuwongolera bwino mbewu za udzu zomwe zimamera komanso zomwe zingamere. Ponena za kuwononga chilengedwe, cyhalofop-butyl imayesedwa kuti ione ngati ili yotetezeka, ndipo maphunziro amachitika kuti awone momwe imakhudzira zamoyo zomwe sizili m'gulu la zomera komanso momwe zingakhudzire madzi apansi panthaka. Njira zoyenera zogwiritsira ntchito komanso kutsatira mlingo woyenera ndizofunikira kwambiri pochepetsa zoopsa ku zachilengedwe zozungulira. Ponseponse, cyhalofop-butyl ester ndi chinthu chofunikira kwambiri pa mankhwala ophera udzu kwa alimi, makamaka m'madera omwe udzu umakhala ndi vuto lalikulu pa zokolola za mbewu, kuonetsetsa kuti udzu ukusamalidwa bwino komanso kulimbikitsa ulimi wokhazikika.
