Brazil Ibama calls for new imidacloprid tests
The Brazilian environmental agency, the Ibama, is to conduct “more specific” studies on the neonicotinoid insecticide, imidacloprid, and two other substances’ residues resulting from degradation in pollen, leaves and soil. It is to form part of the agency’s reassessment of the active ingredient that started in July over concerns about its impact on the health of bees ( Agrow No 645, p 16). Studies will cover seven selected crops: citrus fruit, coffee, cotton, maize, melons, soybeans and sugar cane. The Ibama has requested that registrants present proposals for carrying out three “semi-field” trials, which would allow it to perform pesticide exposure tests on bees under “more realistic” and controlled conditions, with the help of installed tunnels.
