Maxkamad ku taal Brazil ayaa amartay in la mamnuuco dhirta 2,4-D ee khamriga iyo tufaaxa muhiimka ah ee koonfurta

Maxkamad ku taal koonfurta Brazil ayaa dhawaan amartay in si degdeg ah loo mamnuuco 2,4-D, oo ka mid ah kuwa ugu isticmaalka badanherbicidesadduunka oo dhan, gobolka Campanha Gaucha ee koonfurta dalka. Gobolkani waa saldhig muhiim u ah soo saarista khamriga wanaagsan iyo tufaaxa Brazil.

Xukunkan ayaa la sameeyay horraantii Sebtembar iyadoo looga jawaabayo dacwad madani ah oo uu gudbiyay ururka beeralayda maxalliga ah. Ururka beeralayda ayaa ku andacoodey in kiimikadu ay waxyeelo u gaysatay beero canab ah iyo beero tufaax ah iyada oo loo marayo wakiilo. Sida ku xusan xukunka, 2,4-D waa inaan loo isticmaalin meel kasta oo ka mid ah aagga Campanha Gaucha. Meelaha kale ee Rio Grande do Sul, waa mamnuuc in lagu buufiyo dhir-dhimistaan ​​50 mitir oo beero canab ah iyo beero tufaax ah. Mamnuuciddan ayaa sii jiri doonta ilaa ay dawlad-goboleedka ka hirgelinayso nidaam la socodka iyo ilaalinta sharciga oo dhammaystiran, oo ay ku jirto samaynta aagagga aan la isticmaalin ee meelaha khatarta sare leh.

Maamulka deegaanka ayaa la siiyay 120 maalmood si ay u hirgeliyaan nidaamka cusub. Ku guuldareysiga inaad u hogaansanto waxay keeni doontaa ganaax maalinle ah 10,000 reais (qiyaastii 2,000 US dollars), kaas oo loo wareejin doono sanduuqa magdhowga deegaanka ee gobolka. Xukunku waxa kale oo uu uga baahan yahay dawladda in ay si weyn u shaaciso mamnuucistan beeralayda, tafaariiqda kiimikada iyo dadweynaha.

2,4-D (2, 4-dichlorophenoxyacetic acid) ayaa si weyn loo isticmaali jiray ilaa 1940-meeyadii, badi ahaan soybean-ka, sarreenka iyo beeraha galleyda. Si kastaba ha ahaatee, dabeecadeeda kacsan iyo u janjeedhsiga ay ugu dhaqaaqdo meelaha u dhow ayaa ka dhigtay diiradda muranka u dhexeeya beeralayda badarka iyo kuwa miraha soo saara ee koonfurta Brazil. Beero canab ah iyo beero tufaax ah ayaa si gaar ah ugu nugul walaxdan kiimikada ah. Xataa qulqulka yar wuxuu si dhab ah u saameyn karaa tayada miraha, taasoo keenaysa cawaaqib dhaqaale oo weyn oo ku saabsan khamriga iyo warshadaha dhoofinta miraha. Beeralayda ayaa aaminsan in la'aanteed adag la'aanteed, goosashada oo dhan waxay noqon doontaa khatar.

Tani maaha markii ugu horeysay ee Rio Grande do Sul ay isku dhacaan 2,4-D. Maamulka maxalliga ah ayaa hore u hakiyay isticmaalka daawoyinka, laakiin tani waa mid ka mid ah xannibaadaha ugu adag ee Brazil laga hirgaliyay ilaa hadda. Khubarada beeraha ayaa sheegaya in kiiska sharcigu uu horudhac u noqon karo sharciga adag ee sunta cayayaanka ee gobollada kale ee Brazil, taasoo muujineysa xiisadaha u dhexeeya noocyada kala duwan ee beeraha: beerashada hadhuudhka sare iyo warshadaha miraha iyo khamriga ee ku tiirsan tayada badeecada iyo badbaadada deegaanka.

In kasta oo xukunka weli laga dacwoon karo, amarka 2,4-D wuxuu ahaan doonaa mid dhaqan gala ilaa go'aannada kale ay gaarto Maxkamadda Sare.
