Brazil examines pollinators and pesticides
Ongoing impact studies in Brazil of certain pesticides on pollinators have resulted in the first national publication that gathers relevant information on the matter, the environmental agency, the Ibama, reports. The publication collates literature on pollination ecosystems and the main pollinators in various parts of the country, and the possible effects of pesticides on the survival of bee colonies. The Ibama is to reassess the use approvals for neonicotinoid insecticides based on imidacloprid, thiamethoxam, clothianidin and fipronil due to concerns over their effect on bees ( Agrow No 645, p 16). It also ordered a precautionary ban earlier this year on the aerial application of products based on the active ingredients, but has since granted conditional exceptional use authorisations until June 30th next year (see this issue).
