Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has concluded that the addition of new uses on sweet corn to the product label Impact Herbicide, containing technical grade topramezone, is acceptable. Before registering a pesticide for food use in Canada, the PMRA must determine the quantity of residues that are likely to remain in or on the food when the pesticide is used according to label directions and that such residues will not be a concern to human health. This quantity is then legally established as a maximum residue limit (MRL). This paper reviews the level of legally established maximum residual level (MRLs) of topramezone in or on food, to be added to those MRLs already legally established, as well as presenting a table on proposed maximum residue limits.--Includes text from document.
