Muva nje, i-Brazilian Environmental Protection Agency Ibama ikhiphe imithetho emisha yokulungisa ukusetshenziswa kwezibulala-zinambuzane eziqukethe isithako esisebenzayo i-thiamethoxam.Imithetho emisha ayikuvimbi ngokuphelele ukusetshenziswa kwezibulala-zinambuzane, kodwa iyakwenqabela ukufafazwa ngokungafanele kwezindawo ezinkulu ezitshalweni ezihlukahlukene ngezindiza noma ngogandaganda ngoba isifutho sivame ukukhukhuleka futhi sithinte izinyosi nezinye izithuthi zempova ku-ecosystem.
Ezitshalweni ezithile ezinjengomoba, i-Ibama incoma ukusetshenziswa kwe-thiamethoxam equkethe izibulala-zinambuzane ezindleleni zokufaka ezinembayo ezifana nokunisela nge-drip ukugwema izingozi zokukhukhuleka.Ongoti bezolimo bathi i-drip irrigation ingafaka izibulala-zinambuzane ngokuphepha nangempumelelo ezitshalweni zomoba, Isetshenziselwa ukulawula izinambuzane ezinkulu ezifana ne-Mahanarva fimbriolata, umuhlwa i-Heterotermes tenuis, iziqhumane zomoba (Diatraea saccharalis) kanye ne-sweevil (Sphenophorus levis).Umthelela omncane ezitshalweni.
Imithetho emisha ikwenza kucace ukuthi izibulala-zinambuzane ze-thiamethoxam ngeke zisakwazi ukusetshenziselwa ukwelapha ngamakhemikhali embonini yezinto zokuzalanisa umoba.Nokho, ngemva kokuba umoba usuvuniwe, izibulala-zinambuzane zisengafakwa emhlabathini ngokusebenzisa izinhlelo zokunisela nge-drip.Ukuze ugweme ukuthinta izinambuzane ze-pollinator, kunconywa ukuthi kushiywe izinsuku ezingama-35-50 phakathi kokunisela kokuqala nokulandelayo.
Ngaphezu kwalokho, imithetho emisha izovumela ukusetshenziswa kwezibulala-zinambuzane ze-thiamethoxam ezitshalweni ezinjengommbila, ukolweni, ubhontshisi kabhontshisi kanye nomoba, okusetshenziswe ngokuqondile enhlabathini noma emaqabunga, kanye nokwelashwa kwembewu, ngezimo ezithile ezifana nomthamo kanye nosuku lokuphelelwa yisikhathi. kucaciswe.
Ochwepheshe baveze ukuthi ukusetshenziswa komuthi onembile njengokunisela nge-drip akukwazi nje ukulawula kangcono izifo nezinambuzane, kodwa futhi kuqinisekise ukuphepha kokusebenza nokunciphisa okokufaka komuntu, okuwubuchwepheshe obusha obuqhubekayo nobusebenzayo.Uma kuqhathaniswa nokusebenza ngokufutha, ukuchelela nge-drip kugwema ukulimala okungaba khona kokukhukhuleka okuwuketshezi endaweni ezungezile kanye nabasebenzi, futhi kunobungani bemvelo futhi kunokonga futhi kusebenza ngokuphelele.
