Brazil's Ministry of Agriculture and Livestock (Mapa) has declared a state of phytosanitary emergency in response to the detection of the quarantine pest, Rhizoctonia theobromae or cassava witch's broom, in the states of Amapá and Pará. This emergency, outlined in ordinance no. 769, aims to bolster prevention efforts and limit the pest's spread, especially given its new arrival from abroad. Initially identified in August 2024 on indigenous lands in Oiapoque, Amapá, the pest poses a significant threat to cassava crops, leading to symptoms such as plant deformation and death. To tackle this crisis effectively, a National Emergency Command involving federal, state, and private sector entities will be established. All actions will focus on containing the pest and preventing its spread to other regions, highlighting Brazil's commitment to safeguarding its agricultural sector.
