791-31-1: INkcazelo yoQhagamshelwano oluPhambili

Kwintsimi yeekhemikhali, i-ID791-31-1ibhekisa kwikhompawundi ethile etsale ingqwalasela kwizicelo ezahlukeneyo zenzululwazi nezoshishino. Esi sichongi sahlukileyo siyinxalenye yobhaliso lwe-CAS, olunikezela ngesazisi samanani esisodwa kwikhemikhali nganye ukuququzelela unxibelelwano kunye nophando kuluntu lwenzululwazi yehlabathi.

Ikhompawundi enxulumene neI-CAS 791-31-1ibizwa ngokuba yi-2,4-dichlorobenzoic acid (idla ngokufinyezwa njenge-2,4-D). Lo mchiza usetyenziswa kakhulu ukusukela oko waziswa ngeminyaka yoo-1940, ingakumbi ukulawula ukhula lwamagqabi abanzi kwiindawo zezolimo. Ukusebenza kwayo kakuhle kunye neendleko eziphantsi ngokwentelekiso kuyenza ibe yeyona nto iphambili kukutya kwezolimo, ngakumbi ekulinyweni kwezityalo ezinjengombona nengqolowa.

I-2,4-D isebenza ngokulinganisa i-isomers yezityalo zendalo eziphazamisa iipateni eziqhelekileyo zokukhula kwezityalo ezibuthathaka. Le ndlela yokusebenza ivumela ukujoliswa okukhethiweyo kunye nokutshatyalaliswa kwezityalo ezingafunekiyo ngelixa kugcinwa izivuno zezityalo ngaphandle komonakalo. Nangona kunjalo, ukusetyenziswa kwe-2,4-D ayikho ngaphandle kwengxabano. Ukukhathazeka malunga nefuthe layo lokusingqongileyo kunye neengozi zempilo ezinokuthi zikhokelele amazwe amaninzi ukuba aqinise ulawulo kunye nolawulo.

Kwiminyaka yakutshanje, uphando lujolise ekuphuhliseni iindlela ezikhuselekileyo nezisebenzayo kwi-2,4-D, kunye nokuhlola indima yabo kwizicwangciso ezidibeneyo zokulawula izinambuzane. Ukuqonda iimpawu kunye nokusetyenziswa kwe-791-31-1 kubalulekile kwiingcali zezolimo kunye neengcali zenzululwazi ngokusingqongileyo njengoko zikwazi ukujamelana nobunzima beendlela zezolimo zanamhlanje.

Isishwankathelo, i-791-31-1 okanye i-2,4-D iyikhompawundi ebalulekileyo enembali etyebileyo kwezolimo. Ukusetyenziswa kwayo ngokuqhubekayo kunye nophando oluqhubekayo olujikeleze kuyo kugxininisa ukulingana phakathi kolawulo olusebenzayo lokhula kunye nolawulo lokusingqongileyo.
