Pa Seputembala 7, 2023, Ofesi Yaikulu ya Unduna wa Zaulimi ndi Zakumidzi idapereka kalata yopempha maganizo pakugwiritsa ntchito njira zoletsa kuyang'anira mankhwala anayi oopsa kwambiri, kuphatikizapo omethoate. Malingalirowo akuti kuyambira pa Disembala 1, 2023, bungwe lopereka mankhwala lidzachotsa kulembetsa kwa omethoate, carbofuran, methomyl, ndi aldicarb, kuletsa kupanga, ndipo zomwe zapangidwa mwalamulo zitha kugulitsidwa ndikugwiritsidwa ntchito mkati mwa nthawi yotsimikizira khalidwe. Kuyambira pa Disembala 1, 2025, kugulitsa ndi kugwiritsa ntchito zinthu zomwe zili pamwambapa ndizoletsedwa; Sungani kupanga ndi kutumiza zinthu zopangira ndi kutumiza kunja kwa makampani opanga zinthu zopangira, ndikukhazikitsa kuyang'anira ntchito yotsekedwa. Kutulutsidwa kwa malingalirowa kungatanthauze kuchoka kwa KPMG, yomwe yalembedwa ku China kwa zaka zoposa makumi asanu kuyambira m'ma 1970, pamsika waulimi waku China.
Carbofuran ndi mankhwala ophera tizilombo otchedwa carbamate omwe amapangidwa pamodzi ndi FMC ndi Bayer, omwe amagwiritsidwa ntchito kupha nthata, tizilombo, ndi mimbulu. Amayamwa mkati, amapha tizilombo toyambitsa matenda, komanso amapha m'mimba, ndipo amakhala ndi mphamvu yopha mazira. Amakhala nthawi yayitali ndipo nthawi zambiri amakhala ndi theka la moyo wa masiku 30-60 m'nthaka. Kale ankagwiritsidwa ntchito kwambiri m'minda ya mpunga kuti athetse tizilombo toyambitsa matenda monga mpunga, tizilombo toyambitsa matenda monga mphutsi ..., tizilombo toyambitsa matenda monga mphutsi, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda monga mphutsi, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda monga mphutsi, tizilombo toyambitsa matenda, ndi tizilombo toyambitsa matenda m'minda ya thonje. Pakadali pano, amagwiritsidwa ntchito kwambiri m'minda yopanda mbewu monga mitengo ndi minda yobiriwira, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda monga mphutsi, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda monga mphutsi, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda monga mphutsi, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda monga mphutsi, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda monga mphutsi, tizilombo toyambitsa matenda, ndi tizilombo toyambitsa matenda m'minda ya thonje.
Carbofuran ndi mankhwala oletsa acetylcholinesterase, koma mosiyana ndi mankhwala ena ophera tizilombo a carbamate, kugwirizana kwake ndi cholinesterase sikungatheke, zomwe zimapangitsa kuti pakhale poizoni wambiri. Carbofuran imatha kuyamwa ndi mizu ya zomera ndikusamutsidwa kupita ku ziwalo zosiyanasiyana za chomera. Imasonkhanitsa zambiri m'masamba, makamaka m'mphepete mwa tsamba, ndipo imakhala ndi kuchuluka kochepa mu chipatso. Tizilombo tikamatafuna ndikuyamwa madzi a masamba a zomera za poizoni kapena kuluma minofu ya poizoni, acetylcholinesterase m'thupi la tizilombo imalepheretsedwa, zomwe zimayambitsa poizoni wa mitsempha ndi imfa. Hafu ya moyo m'nthaka ndi masiku 30-60. Ngakhale kuti yagwiritsidwa ntchito kwa zaka zambiri, pali malipoti oti sitingathe kukana carbofuran.
Carbofuran ndi mankhwala ophera tizilombo omwe amagwiritsidwa ntchito kwambiri m'munda waulimi. Komabe, m'zaka zaposachedwa, carbofuran yathetsedwa pang'onopang'ono ndipo ikutsimikizika kuti ituluka kwathunthu pamsika waku China pofika kumapeto kwa chaka cha 2025. Kusintha kwakukulu kumeneku kudzakhudza kwambiri ulimi waku China. Komabe, pamapeto pake, izi zitha kukhala sitepe yofunikira pakukula kwaulimi kokhazikika komanso njira yosapeweka yopititsira patsogolo ulimi wosawononga chilengedwe.
