Urukiko rwo muri Brezili rwategetse ko umuti wica udukoko wa 2,4-D uhagarikwa mu turere tw’ingenzi twa divayi n’amapera mu majyepfo

Urukiko rwo mu majyepfo ya Brezili ruherutse gutanga itegeko ryo guhagarika ako kanya 2,4-D, imwe mu zikoreshwa cyaneimiti yica ibyatsiku isi, mu gace ka Campanha Gaucha mu majyepfo y'igihugu. Aka karere ni ingenzi mu gukora divayi nziza n'imbuto z'amapera muri Brezili.

Iki cyemezo cyafashwe mu ntangiriro za Nzeri mu gusubiza ikirego cy’imbonezamubano cyatanzwe n’ishyirahamwe ry’abahinzi bo muri ako gace. Ishyirahamwe ry’abahinzi ryavuze ko uyu muti wangije imirima y’imizabibu n’imirima y’amapera binyuze mu kuyobya uburari. Nk’uko icyemezo cyabyemeje, 2,4-D ntigomba gukoreshwa ahantu hose mu gace ka Campanha Gaucha. Mu tundi duce twa Rio Grande do Sul, birabujijwe gutera uyu muti muri metero 50 uvuye ku mirima y’imizabibu n’imirima y’amapera. Iri tegeko rizakomeza gukoreshwa kugeza igihe guverinoma y’igihugu izashyiraho uburyo bwuzuye bwo kugenzura no kubahiriza amategeko, harimo no gushyiraho uduce tudakoreshwa mu turere dushobora kwibasirwa n’impanuka nyinshi.

Abayobozi b'inzego z'ibanze bahawe iminsi 120 yo gushyira mu bikorwa ubu buryo bushya. Kutubahiriza ibyo bikorwa bizatuma bacibwa amande ya buri munsi angana na reais 10.000 (hafi amadolari 2.000 y'Amerika), azashyirwa mu kigega cy'indishyi ku bidukikije cya leta. Uyu mwanzuro usaba kandi guverinoma gutangaza cyane iri tegeko ku bahinzi, abacuruzi b'ibikomoka ku bimera n'ibikomoka ku buhinzi ndetse n'abaturage.

2,4-D (2, 4-dichlorophenoxyacetic aside) yakoreshejwe cyane kuva mu myaka ya 1940, cyane cyane mu mirima ya soya, ingano n'ibigori. Ariko, imiterere yayo ihindagurika ndetse n'uburyo ikunda gutembera mu turere twegereye byatumye iba intandaro y'amakimbirane hagati y'abahinzi b'ibinyampeke n'abakora imbuto mu majyepfo ya Brezili. Inzabibu n'imirima y'imbuto z'amapera bigira ingaruka zikomeye kuri iki kintu cy'ubutabire. Ndetse n'amazi make ashobora kugira ingaruka zikomeye ku bwiza bw'imbuto, bigatera ingaruka zikomeye ku bukungu ku nganda zohereza divayi n'imbuto mu mahanga. Abahinzi bizera ko hatabayeho kugenzura cyane, umusaruro wose uzaba uri mu kaga.

Si ubwa mbere Rio Grande do Sul ihanganye ku kibazo cya 2,4-D. Abayobozi b'ibanze bari bahagaritse ikoreshwa ry'umuti wica udukoko, ariko iyi ni imwe mu mabwiriza akomeye yashyizweho muri Brezili kugeza ubu. Impuguke mu by'ubuhinzi zivuga ko uru rubanza rushobora kuba icyitegererezo cyo gushyiraho amategeko akaze agenga imiti yica udukoko mu zindi leta za Brezili, bigaragaza amakimbirane ari hagati y’uburyo butandukanye bw’ubuhinzi: ubuhinzi bw’ibinyampeke bukabije n’inganda z’imbuto na divayi zishingiye ku bwiza bw’ibicuruzwa n’umutekano w’ibidukikije.

Nubwo icyemezo cyafashwe gishobora kujuririrwa, itegeko rya 2,4-D rizakomeza gukoreshwa kugeza igihe ibindi byemezo bizafatwa n'Urukiko Rukuru.
