The Brazilian environmental agency, the Ibama, has suspended foliar and aerial applications of products based on the phenylpyrazole insecticide, fipronil. Soil and direct-toplant applications remain approved. The agency cites the “precautionary principle” to protect pollinators for its move. The suspension will last until the agency concludes its reassessment of the insecticide. A communique was issued in the official gazette late last month. Fipronil has been under an Ibama reassessment since September 2022. Studies so far carried out have indicated potential unacceptable environmental risk factors for all approved foliar application products for bees due to spray drift, the Ibama notes.
