Isoxaflutole HPPD inhibitor herbicide yo kurwanya nyakatsi

Ibisobanuro ku bicuruzwa

Isoxaflutole ni imiti yica ibyatsi - ihindurwa mu gihingwa cyose nyuma yo kwinjizwa mu mizi no mu mababi hanyuma igahinduka vuba muri planta ikagera kuri diketonitrile ikora ibinyabuzima, igahita yanduzwa na metabolite idakora, 2-methylsulphonyl-4-trifluoromethylbenzoic.Igikorwa cyibicuruzwa kinyuze mu kubuza enzyme p-hydroxy phenyl pyruvate dioxygenase (HPPD), ihindura p-hydroxy phenyl pyruvate na homogentisate, intambwe yingenzi muri biosynthesis ya plastoquinone.Isoxaflutole igenzura ibyatsi byinshi hamwe n’ibyatsi bigari mu guhumanya ibyatsi bivuka cyangwa byagaragaye nyuma yo gufata ibyatsi biva mu mizi.Gukurikiza ibibabi cyangwa imizi, isoxaflutole ihindurwamo byihuse inkomoko ya diketonitrile (2-cyclopropyl-3- (2-mesyl-4-trifluoromethylphenyl) -3-oxopropanenitrile) ifungura impeta ya isoxazole.

Isoxaflutole irashobora gukoreshwa mbere yo kugaragara, mbere yo gutera cyangwa mbere y-ibimera byinjijwe mu bigori mbere yo kuvuka cyangwa mbere yo kugaragara hakiri kare mu bisheke.Igipimo cyo hejuru kirakenewe kubisabwa mbere yo guhinga.Mu bigeragezo byo mu murima, isoxaflutole yatanze urwego rusa rwo kugenzura imiti yica ibyatsi ariko ku kigero cyo kuyikoresha hafi inshuro 50.Irwanya nyakatsi irwanya triazine iyo ikoreshejwe wenyine no mu mvange.Isosiyete irasaba ko ikoreshwa mu mvange, no mu kuzunguruka cyangwa mu buryo bukurikiranye hamwe n’ibindi byatsi byica imiti kugira ngo bidindiza gutangira guhangana.

Isoxaflutole, ifite igice cya kabiri cyamasaha 12 kugeza kumunsi 3, bitewe nubwoko bwubutaka nibindi bintu, nayo ihinduka diketonitrile mubutaka.Isoxaflutole igumishwa hejuru yubutaka, bigatuma ishobora gutwarwa nubutaka bwera imbuto zibyatsi, mu gihe diketonitrile, ifite ubuzima bwa kimwe cya kabiri cyiminsi 20 kugeza 30, yinjira mubutaka kandi igatwarwa numuzi wibiti.Mu bimera ndetse no mu butaka, diketonitrile ihindurwamo aside ya benzoic idakora ibyatsi.

Ibicuruzwa ntibigomba gukoreshwa mubutaka bwumucanga cyangwa bubi cyangwa kubutaka bufite ibintu bitarenze 2%.Mu rwego rwo kurwanya uburozi bushobora guterwa n’amafi, ibimera byo mu mazi n’inyamaswa zidafite ubuzima, hasabwa akarere ka metero 22 kugira ngo karinde uduce tworoshye, nk'ibishanga, ibidendezi, ibiyaga n’inzuzi.
