Bracken can overwhelm sensitive habitats and threaten grazing land and the establishment of new tree plantings. This is why, after very careful consideration, an emergency authorisation has been granted for the limited and strictly controlled use of Asulox to control bracken in England in 2023. The application for emergency authorisation was considered according to the legal tests and it was concluded that authorisation was necessary because of a danger that could not be controlled by other reasonable means, there were special circumstances, and the use of the product would be limited and controlled, with strict conditions in place to minimise the impacts to the environment and wildlife.
