Isoxaflutole HPPD inhibitor herbicide yekudzora sora

Chigadzirwa tsananguro

Isoxaflutole is a systemic herbicide - inofambiswa muchirimwa ichitevera kunyura kuburikidza nemidzi nemashizha uye inokurumidza kushandurwa muplanta kuenda kune biologically inoshanda diketonitrile, iyo inozobviswa kune isingashande metabolite, 2-methylsulphonyl-4-trifluoromethylbenzoic acid.Chiitiko chechigadzirwa chiri kuburikidza nekudzivirirwa kwe enzyme p-hydroxy phenyl pyruvate dioxygenase (HPPD), iyo inoshandura p-hydroxy phenyl pyruvate kuita homogentisate, danho rinokosha muplastoquinone biosynthesis.Isoxaflutole inodzora huswa hwakasiyana-siyana nemasora akatambanudzwa nekuchenesa masora ari kubuda kana kubuda zvichitevera kutorwa kwemushonga wesora kuburikidza nemidzi.Kutevera kutorwa kwefoliar kana midzi, isoxaflutole inokurumidza kushandurwa kuita diketonitrile derivative (2-cyclopropyl-3-(2-mesyl-4-trifluoromethylphenyl) -3-oxopropanenitrile) nekuvhura mhete ye isoxazole.

Isoxaflutole inogona kuiswa pre-emergence, pre-plant kana pre-plant yakabatanidzwa muchibage uye chisati chamera kana kukurumidza-kumera munzimbe.Mwero wepamusoro unodiwa kune pre-plant applications.Mumiyedzo yemumunda, isoxaflutole yakapa mazinga akafanana ekutonga kune akajairwa marapirwo emishonga yesora asi pamitengo yekushandiswa inoderera zvakapetwa ka50.Inodzora sora risingamirire triazine kana richishandiswa riri roga uye mumisanganiswa.Kambani inokurudzira kuti ishandiswe mumisanganiswa, uye mukutenderera kana kutevedzana nemimwe mishonga yesora kunonotsa kutanga kwekurwisa.

Isoxaflutole, ine hafu yehupenyu hwemaawa gumi nemaviri kusvika kumazuva matatu, zvichienderana nemhando yevhu uye zvimwe zvinhu, inoshandurawo kuita diketonitrile muvhu.Isoxaflutole inochengetwa pamusoro pevhu, ichibvumira kuti itorerwe nembeu yesora iri kumera, nepo diketonitrile, ine hafu yehupenyu hwemazuva makumi maviri kusvika makumi matatu, inopinda muvhu uye inotorwa nemidzi yezvirimwa.Muzvirimwa zvese nemuvhu, diketonitrile inoshandurwa kuita herbicidally inactive benzoic acid.

Chigadzirwa ichi hachifanirwe kuiswa kune ivhu rejecha kana rakarukwa kana kune ivhu rine organic zvinhu zvisingasviki 2%.Kuti varwise huturu hunogona kuitika kuhove, zvidyarwa zvemumvura nemainvertebrates, 22 metre buffer zone inodiwa kuchengetedza nzvimbo dzakaoma, dzakadai semanyoro, madziva, madziva nenzizi.
