Umujyi wa Kaminuza, muri Pennsylvania — Ingano zo mu gihe cy'itumba zihingwa cyane mu bworozi bw'inkoko mu karere ka Atalantika yo hagati muri Leta Zunze Ubumwe za Amerika mu rwego rwo gukora ibinyampeke n'ibyatsi. Ingano zikoreshwa nk'ibiryo by'amatungo, naho ibyatsi bikoreshwa nk'ibiryo byo kuryamaho.abashinzwe kugenzura iteramberebishobora kongera umusaruro w'ibinyampeke binyuze mu kugabanya gukura kw'ibinyampeke no kugabanya ibyago byo kwibera mu bimera, ibi bikaba bigabanya cyane umusaruro w'ibinyampeke. Ariko, ingaruka z'abashinzwe kugenzura ubwiyongere bw'ibinyampeke ku musaruro n'ubwiza bw'ibyatsi ntizirasobanuka neza. Kubwibyo, itsinda ry'abashakashatsi bo muri Kaminuza ya Leta ya Pennsylvania bakoze ubushakashatsi kugira ngo basuzume ingaruka zabyo.guhuza abashinzwe kugenzura iteramberehamwe n’ibipimo bitandukanye byo gukoresha ifumbire ya azote. Ubu bushakashatsi bwakorewe mu igerageza ry’ingano mu gihe cy’itumba mu kigo cy’ubushakashatsi ku buhinzi cya Russell E. Larson muri Kaminuza ya Leta ya Pennsylvania.
“Abahinzi ntibashaka ko ingano zikura cyane kandi zigasigara, ibyo bikaba byangiza umusaruro w’ingano, bityo abahinzi benshi bamaze igihe kinini bakoresha ibikoresho bigenzura ubwiyongere bw’ibihingwa,” uyu ni Daniela Carrijo, umwarimu wungirije ushinzwe umusaruro w’ibinyampeke n’inzobere mu kwagura ingano muri Koleji y’Ubumenyi bw’Ubuhinzi muri Kaminuza ya Leta ya Pennsylvania. “Tuzi ko ibikoresho bigenzura ubwiyongere bw’ibihingwa bishobora kugabanya ibyago byo gusigara no kongera umusaruro w’ibinyampeke, ariko abahinzi na bamwe mu bafatanyabikorwa bashaka kumenya ingaruka zabyo ku musaruro n’ubwiza bw’ibinyampeke. Uyu ni umushinga ufite ingaruka zifatika, kandi twagerageje ibicuruzwa bikunze gukoreshwa byitwa tricyclazole ethyl ester kugira ngo tumenye ingaruka zabyo ku musaruro n’ubwiza bw’ibinyampeke, kandi ni ingenzi ku mirima ivangwa n’ibihingwa.”
Mu gihe cy'imyaka irenga ibiri, abashakashatsi bagerageje uburyo icyenda bwo gukoresha ifumbire mvaruganda ya azote eshatu n'uburyo butatu bwo gukoresha tricyclazole ethyl ester. Basanze tricyclazole ethyl ester yagabanyije uburebure bw'ibimera ariko ntiyongere ubugari bw'igiti. Uburyo bubiri bwo gukoresha tricyclazole ethyl ester bwagabanije umusaruro w'ibyatsi ku kigero cya 8%, mu gihe uburyo bumwe bwo gukoresha bwagabanije umusaruro w'ibyatsi ku kigero cya 5%, nubwo iri tandukaniro ritari rifite agaciro gakomeye mu mibare. Basanze kandi ko tricyclazole ethyl ester itahinduye ubwiza bw'ibyatsi cyangwa uburyo amazi yinjira - bivuze ko bitagize ingaruka ku bushobozi bw'ibyatsi bwo kubika amazi, bityo ibyo byatsi bishobora gukoreshwa nk'ibiryamirwa by'amatungo. Abashakashatsi bavuze ko ahantu hose habayeho igerageza, kandi ko kongera ifumbire ya azote byatumye poroteyine y'ibinyampeke igabanuka.
“Ibisubizo byacu biratandukanye—twasanze tricyclazole ethyl ester ishobora kugabanya gato umusaruro w’ibyatsi, ariko ntigire ingaruka ku bwiza bw’ibyatsi cyangwa ku musaruro w’ibinyampeke,” Carrijo yagize ati. “Abahinzi bakoresha tricyclazole ethyl ester bagomba gusuzuma ibyiza n’ibibi: bishobora gufasha kugabanya aho bihurira (niba ari ikibazo), ariko bishobora kugabanya gato umusaruro w’ibyatsi. Iri tandukaniro ni ingenzi cyane cyane niba ibyatsi ari umusaruro w’ingenzi mu buhinzi kandi bikoreshwa nk’ibiryamirwa.”
Umwanditsi wa mbere w’ubu bushakashatsi, Larissa Correa, yari umushakashatsi mu ishami ry’ubumenyi bw’ibimera muri Kaminuza ya Leta ya Pennsylvania. Ubu ni umunyeshuri wa kaminuza muri Kaminuza ya Wisconsin-Madison. Ronald Hoover, umuyobozi mukuru wungirije wa gahunda mu ishami ry’ubumenyi bw’ibimera, na we yagize uruhare muri ubu bushakashatsi.
Ubushakashatsi bwatewe inkunga na Syngenta n'Ikigo cy'Igihugu cy'Ibiribwa n'Ubuhinzi cya Minisiteri y'Ubuhinzi ya Amerika.
