Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has added a new use on leaf lettuce to the product labels of Matador 120 Emulsifiable Concentrate Insecticide and Warrior Insecticide, containing technical grade lambda-cyhalothrin. The specific use approved in Canada is detailed on the labels of Matador 120 Emulsifiable Concentrate Insecticide and Warrior Insecticide, Pest Control Products Act Registration Numbers 24984 and 26837, respectively.

A corresponding maximum residue limit (MRL) was proposed in the consultation document published on 10 March 2009, Proposed Maximum Residue Limit PMRL2009-01, Lambda-Cyhalothrin. The PMRA received no comments in response to this consultation.

To comply with Canada's international trade obligations, consultation on the proposed MRL 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 MRL takes legal effect as of the publication date of this document and is in addition to the MRLs already established for lambda-cyhalothrin.
