Muva nje, i-Brazilian Environmental Protection Agency i-Ibama ikhiphe imithetho emisha yokulungisa ukusetshenziswa kwezibulala-zinambuzane eziqukethe isithako esisebenzayo i-thiamethoxam. Imithetho emisha ayikuvimbeli ukusetshenziswa kwezibulala-zinambuzane ngokuphelele, kodwa ivimbela ukufafaza okungalungile kwezindawo ezinkulu ezitshalweni ezahlukahlukene ngezindiza noma ngogandaganda ngoba ukufutha kuvame ukukhukhuleka futhi kuthinte izinyosi nezinye izinambuzane ezithutha impova endaweni ezungezile.
Ezitshalweni ezithile ezifana nomoba, i-Ibama incoma ukusetshenziswa kwe-thiamethoxam equkethe izibulala-zinambuzane ngezindlela zokusebenzisa ngokunembile njengokunisela ngokuconsa ukuze kugwenywe izingozi zokukhukhuleka. Ochwepheshe bezolimo bathi ukunisela ngokuconsa kungasebenzisa izibulala-zinambuzane ngokuphephile nangokuphumelelayo ezitshalweni zomoba, Kusetshenziselwa ukulawula izinambuzane ezinkulu ezifana ne-Mahanarva fimbriolata, izintuthwane i-Heterotermes tenuis, izibungu zomoba (i-Diatraea saccharalis) kanye ne-sugar weevil yomoba (i-Sphenophorus levis). Umthelela omncane ezitshalweni.
Imithetho emisha ikwenza kucace ukuthi izibulala-zinambuzane ze-thiamethoxam azisakwazi ukusetshenziswa ekwelapheni izinto zokuzalanisa umoba ngamakhemikhali asefektri. Kodwa-ke, ngemva kokuba umoba usuvuniwe, izibulala-zinambuzane zingasetshenziswa enhlabathini ngezinhlelo zokunisela ngokuconsa. Ukuze kugwenywe ukuthinta izinambuzane ezithutha impova, kunconywa ukuthi kushiywe izinsuku ezingu-35-50 phakathi kokunisela kokuqala ngokuconsa kanye nolandelayo.
Ngaphezu kwalokho, imithetho emisha izovumela ukusetshenziswa kwezibulala-zinambuzane ze-thiamethoxam ezitshalweni ezifana nommbila, ukolweni, ubhontshisi kanye nomoba, okufakwa ngqo enhlabathini noma emaqabunga, kanye nokwelashwa kwembewu, kanye nemibandela ethile efana nomthamo kanye nosuku lokuphelelwa yisikhathi okuzocaciswa kabanzi.
Ochwepheshe baveze ukuthi ukusetshenziswa kwemithi enembile njengokunisela ngokuconsa akugcini nje ngokulawula kangcono izifo nezinambuzane, kodwa futhi kuqinisekisa ukuphepha kokusebenza nokunciphisa okokufaka kwabantu, okuwubuchwepheshe obusha obuqhubekayo nobusebenzayo. Uma kuqhathaniswa nokusebenza ngokufafaza, ukunisela ngokuconsa kugwema ukulimala okungenzeka kokukhukhuleka koketshezi emvelweni nakubasebenzi, futhi kunobungani nemvelo futhi kuyonga futhi kuyasebenza ngokuphelele.
