Lamulo latsopano la ku Brazil loletsa kugwiritsa ntchito mankhwala ophera tizilombo a thiamethoxam m'minda ya nzimbe likulimbikitsa kugwiritsa ntchito ulimi wothirira pogwiritsa ntchito madontho a madzi

Posachedwapa, bungwe la Brazilian Environmental Protection Agency Ibama lapereka malamulo atsopano kuti asinthe kugwiritsa ntchito mankhwala ophera tizilombo omwe ali ndi thiamethoxam. Malamulo atsopanowa saletsa kugwiritsa ntchito mankhwala ophera tizilombo, koma amaletsa kupopera mankhwala molakwika m'malo akuluakulu pa mbewu zosiyanasiyana ndi ndege kapena mathirakitala chifukwa mankhwalawo amakonda kuyandama ndipo amakhudza njuchi ndi tizilombo tina touluka m'chilengedwe.
Pa mbewu zinazake monga nzimbe, Ibama amalimbikitsa kugwiritsa ntchito mankhwala ophera tizilombo okhala ndi thiamethoxam m'njira zolondola monga kuthirira ndi madontho kuti apewe ngozi zoyenda. Akatswiri a zaulimi amati kuthirira ndi madontho kungathe kugwiritsa ntchito mankhwala ophera tizilombo m'minda ya nzimbe mosamala komanso moyenera. Kumagwiritsidwa ntchito poletsa tizilombo tambiri monga Mahanarva fimbriolata, chiswe Heterotermes tenuis, nzimbe borers (Diatraea saccharalis) ndi nzimbe weevil (Sphenophorus levis). Kuchepetsa mphamvu ya mbewu.

Malamulo atsopanowa akuwonetsa momveka bwino kuti mankhwala ophera tizilombo a thiamethoxam sangagwiritsidwenso ntchito popanga mankhwala opangira nzimbe m'fakitale. Komabe, nzimbe zikakololedwa, mankhwala ophera tizilombo amatha kugwiritsidwabe ntchito m'nthaka kudzera mu njira zothirira zothirira. Pofuna kupewa kukhudza tizilombo toyambitsa mungu, tikukulimbikitsani kuti pakhale masiku 35-50 pakati pa kuthirira koyamba ndi tsiku lotsatira.
Kuphatikiza apo, malamulo atsopanowa alola kugwiritsa ntchito mankhwala ophera tizilombo a thiamethoxam pa mbewu monga chimanga, tirigu, soya ndi nzimbe, zomwe zimagwiritsidwa ntchito mwachindunji panthaka kapena masamba, komanso pochiza mbewu, ndi zinthu zina monga mlingo ndi tsiku lotha ntchito kuti zifotokozedwe bwino.

Akatswiri adanenanso kuti kugwiritsa ntchito mankhwala olondola monga kuthirira pogwiritsa ntchito madontho sikungoletsa matenda ndi tizilombo toononga, komanso kumatsimikizira chitetezo cha ntchito ndikuchepetsa kugwiritsa ntchito kwa anthu, komwe ndi ukadaulo watsopano wokhazikika komanso wogwira ntchito bwino. Poyerekeza ndi ntchito yopopera, kuthirira pogwiritsa ntchito madontho kumapewa kuwonongeka kwa madzi omwe amalowa m'malo ndi antchito, ndipo ndi kosamalira chilengedwe komanso kotsika mtengo komanso kothandiza kwambiri.
