Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has granted conditional registration to the chemical safener cyprosulfamide and the herbicide isoxaflutole for use in Canada on field corn. The specific uses approved in Canada are detailed on the product label of Converge Flexx Herbicide, Pest Control Products Act Registration Number 29071.
Corresponding maximum residue limits (MRLs) for cyprosulfamide were proposed in the consultation document published on 18 March 2011, Proposed Maximum Residue Limit PMRL2011-02, Cyprosulfamide. In addition, import MRLs for cyprosulfamide in or on popcorn and sweet corn were proposed in PMRL2011-02. The PMRA received no comments in response to this consultation.
To comply with Canada's international trade obligations, consultation on the proposed MRLs was also conducted internationally by notifying the World Trade Organization, as coordinated by the Standards Council of Canada. No comments were received as a result of the World Trade Organization consultation.
The following MRLs for cyprosulfamide take legal effect in Canada as of the publication date of this document.
|Common Name||Residue Definition||MRL (ppm)||Food Commodity|
|Cyprosulfamide||N-[[4-[(cyclopropylamino)carbonyl] phenyl]sulfonyl]-2-methoxybenzamide||0.01||Field corn, popcorn grain, sweet corn kernels plus cob with husks removed|
|N-[[4-[(cyclopropylamino)carbonyl] phenyl]sulfonyl]-2-methoxybenzamide, including the metabolite 4-(aminosulfonyl)-N-cyclopropylbenzamide||0.02||Eggs; fat, meat and meat byproducts of cattle, goats, hogs, horses, poultry and sheep|
