Kua whakahaua e te Kōti o Brazil te aukati i te patu taru 2,4-D i ngā rohe waina me te aporo nui o te tonga.

Nō nā tata nei i whakahaua e te Kōti i te tonga o Brazil kia aukatia tonutia te 2,4-D, tētahi o ngā mea e whakamahia whānuitia anangā patu tarui te ao, i te rohe o Campanha Gaucha i te tonga o te whenua. He pūtake nui tēnei rohe mō te hanga waina me ngā aporo pai i Brazil.

I te tīmatanga o Hepetema, i puta tēnei whakataunga hei whakautu i tētahi kereme ā-ture i tukuna e te rōpū kaimahi pāmu o te rohe. I kī te rōpū kaimahi pāmu nā te matū i kino ai ngā māra waina me ngā māra aporo i puta ai te kino. E ai ki te whakataunga, kāore e tika kia whakamahia te 2,4-D i ngā wāhi katoa o te rohe o Campanha Gaucha. I ētahi atu wāhi o Rio Grande do Sul, kua rāhuitia te rehu i tēnei patu taru i roto i te 50 mita o ngā māra waina me ngā māra aporo. Ka mau tonu tēnei aukati kia whakatūria rā anō e te kāwanatanga o te kawanatanga he pūnaha aroturuki me te whakamana ture katoa, tae atu ki te whakatū i ngā rohe kore whakamahi i ngā wāhi mōrearea.

I hoatu he wā ki ngā mana whakahaere ā-rohe kia 120 ngā rā hei whakatinana i te pūnaha hou. Ki te kore e tutuki ngā whakaritenga, ka whiua he whiu moni 10,000 reais (tata ki te 2,000 tāra US) ia rā, ka tukuna ki te tahua utu taiao a te kawanatanga. E hiahiatia ana hoki e te whakataunga kia pānuitia whānuitia e te kāwanatanga tēnei aukati ki ngā kaimahi pāmu, ki ngā kaihokohoko matū ahuwhenua me te marea.

Kua whānuitia te whakamahinga o te 2,4-D (2, 4-dichlorophenoxyacetic acid) mai i te tekau tau atu i 1940, ko te nuinga i roto i ngā māra pīni, witi me te kānga. Heoi, nā tōna āhua pōturi me te tere o te rere ki ngā rohe tata, kua waiho hei kaupapa tautohetohe i waenga i ngā kaiwhakatipu witi me ngā kaihanga hua i te tonga o Brazil. He tino pāngia ngā māra waina me ngā māra āporo e tēnei matū. Ahakoa he iti noa te rere ka pā kino ki te kounga o ngā hua, ka puta he pānga nui ki te ōhanga mō ngā ahumahi waina me te kaweake hua. E whakapono ana ngā kaiwhakatipu, ki te kore e tino tirotirohia, ka tūpono te kotinga katoa.

Ehara i te mea ko te wā tuatahi tēnei kua taupatupatu a Rio Grande do Sul mō te 2,4-D. I whakamutua e ngā mana whakahaere ā-rohe te whakamahinga o te patu taru i mua, engari koinei tētahi o ngā here tino kaha kua whakatinanahia i Brazil tae noa ki tēnei wā. E ai ki ngā tohunga ahuwhenua, ka taea e te take ture te whakatakoto i tētahi tauira mō te ture patu taru tino kaha ake i roto i ētahi atu whenua o Brazil, e whakaatu ana i ngā taupatupatu i waenga i ngā tauira ahuwhenua rerekē: te whakatipu witi kaha me ngā ahumahi hua me te waina e whakawhirinaki ana ki te kounga hua me te haumaru taiao.

Ahakoa ka taea tonu te piira i te whakataunga, ka mau tonu te mana o te aukati 2,4-D kia tae rā anō ki te wā e whakatauhia ai ētahi atu whakataunga e te Kōti Matua.
