Itegeko rishya rya Brezili ryo kugenzura ikoreshwa ry'imiti yica udukoko ya thiamethoxam mu mirima y'ibisheke risaba gukoresha uburyo bwo kuhira amazi mu buryo bwa drip irrigation

Vuba aha, Ikigo gishinzwe kurengera ibidukikije cya Brezili cyitwa Ibama cyasohoye amabwiriza mashya yo guhindura ikoreshwa ry’imiti yica udukoko irimo thiamethoxam. Amategeko mashya ntabwo abuza burundu ikoreshwa ry’imiti yica udukoko, ahubwo abuza gutera ahantu hanini ku bihingwa bitandukanye hakoreshejwe indege cyangwa traktori mu buryo butari bwo kuko iyo miti ikunda gutemba no kugira ingaruka ku nzuki n’izindi nyamaswa mu rusobe rw’ibinyabuzima.
Ku bihingwa byihariye nk'ibisheke, Ibama isaba ikoreshwa ry'imiti yica udukoko ya thiamethoxam mu buryo bwiza bwo kuyikoresha nko kuhira ibisheke kugira ngo hirindwe ingaruka zo gutemba. Impuguke mu by'ubuhinzi zivuga ko kuhira ibisheke bishobora gukoresha imiti yica udukoko mu buryo bwizewe kandi bunoze mu bihingwa by'ibisheke, bikoreshwa mu kurwanya udukoko twinshi nka Mahanarva fimbriolata, termites Heterotermes tenuis, borers z'ibisheke (Diatraea saccharalis) na weevil y'ibisheke (Sphenophorus levis). Ingaruka nke ku bihingwa.

Amabwiriza mashya agaragaza neza ko imiti yica udukoko ya thiamethoxam itagishobora gukoreshwa mu gutunganya imiti ikomoka ku bimera by’ibisheke mu nganda. Ariko, nyuma yo gusarura ibisheke, imiti yica udukoko ishobora gushyirwa mu butaka binyuze mu buryo bwo kuhira. Kugira ngo hirindwe ingaruka ku dukoko dutera ubwandu, ni byiza ko hasigara iminsi 35-50 hagati yo kuhira ubwa mbere n’ubutaha.
Byongeye kandi, amategeko mashya azemerera ikoreshwa ry’imiti yica udukoko ya thiamethoxam ku bihingwa nk’ibigori, ingano, soya n’ibisheke, bishyirwa ku butaka cyangwa ku mababi, no mu kuvura imbuto, hamwe n’ibipimo byihariye nk’ingano n’itariki bizarangiriraho bigomba gusobanurwa neza.

Impuguke zagaragaje ko gukoresha imiti ivura neza nko kuhira amazi mu buryo butose bitashobora gusa kurwanya indwara n'udukoko, ahubwo binatuma habaho umutekano mu mikorere no kugabanya umusaruro w'abantu, ari naryo koranabuhanga rishya rirambye kandi rinoze. Ugereranyije no gukoresha imiti itera imiti, kuhira amazi mu buryo butose birinda ingaruka mbi zishobora guterwa n'amazi ku bidukikije no ku bakozi, kandi ni byiza ku bidukikije kandi bihendutse kandi bifite akamaro muri rusange.
