791-31-1: Kufotokozera Kwamalumikizidwe Ofunikira

Pankhani yamankhwala, ID 791-31-1 imatanthawuza gulu linalake lomwe lakopa chidwi pazogwiritsa ntchito zosiyanasiyana zasayansi ndi mafakitale. Chizindikiritso chapaderachi ndi gawo la kaundula wa CAS, womwe umapereka chizindikiritso cha manambala ku mankhwala aliwonse kuti athandizire kulumikizana ndi kafukufuku pagulu la asayansi padziko lonse lapansi.

Chigwirizano chogwirizana ndiChithunzi cha CAS 791-31-1amatchedwa 2,4-dichlorobenzoic acid (nthawi zambiri amafupikitsidwa ngati 2,4-D). Mankhwalawa akhala akugwiritsidwa ntchito kwambiri kuyambira pomwe adakhazikitsidwa mzaka za m'ma 1940, makamaka pothana ndi udzu m'malo aulimi. Kuchita bwino kwake komanso kutsika mtengo kwake kumapangitsa kukhala chakudya chofunikira kwambiri paulimi, makamaka pakulima mbewu monga chimanga ndi tirigu.

2,4-D imagwira ntchito potengera ma isomers achilengedwe a zomera zomwe zimasokoneza kakulidwe koyenera ka zomera zomwe zimakhudzidwa. Kachitidwe kameneka kameneka kamalola kulunjika kosankha ndi kuwononga zomera zosafunikira kwinaku akusunga zokolola popanda kuwonongeka. Komabe, kugwiritsa ntchito 2,4-D sikuli kopanda kutsutsana. Kudera nkhawa za momwe chilengedwe chimakhudzira komanso kuopsa kwa thanzi lapangitsa kuti mayiko ambiri alimbikitse kuwongolera ndi kuwongolera.

M'zaka zaposachedwa, kafukufuku adayang'ana kwambiri pakupanga njira zotetezeka komanso zogwira mtima kwambiri za 2,4-D, ndikuwunika gawo lawo munjira zophatikizika zothana ndi tizirombo. Kumvetsetsa mawonekedwe ndi kugwiritsa ntchito kwa 791-31-1 ndikofunikira kwa akatswiri azaulimi ndi asayansi azachilengedwe chifukwa amatha kuthana ndi zovuta zaulimi wamakono.

Mwachidule, 791-31-1 kapena 2,4-D ndi gawo lofunikira lomwe lili ndi mbiri yakale yaulimi. Kugwiritsiridwa ntchito kwake kosalekeza ndi kufufuza kosalekeza kuzungulira izo kumagogomezera kulinganiza pakati pa kasamalidwe koyenera ka udzu ndi kasamalidwe ka chilengedwe.
