Canada to re-register chlorsulfuron:
The Canadian Pest Management Regulatory Agency (PMRA) has recommended the continued registration of the herbicide, chlorsulfuron, provided that certain risk mitigation measures are carried out. They include a 12-hour restricted entry interval, a limit of one application per season and buffer zones to protect aquatic and terrestrial habitats. The PMRA's action is based on a 2005 re-registration eligibility decision by the US EPA (Agrow No 479, p 14), taking Canadian conditions into account. Chlorsulfuron is registered by DuPont for use on cereals and non-crop applications.
