Summary

The purpose of this document is to notify registrants, pesticide regulatory officials and the Canadian public of a voluntary cancellation in the United States of certain uses of the organophosphate insecticide diazinon by the basic manufacturers of the technical active ingredient. The cancellations will take place in phases over a three- to four-year period. This action will include cancellation of all indoor uses and some outdoor uses of diazinon, including all uses on lawns and turf. The following agricultural uses will also be cancelled and tolerances revoked: alfalfa, celery, chicory (radicchio), citrus, coffee, cotton, cowpeas, cucumbers, dandelions, grass (forage), lespedeza, parsley, parsnips, peanuts, pecans, potatoes, rangeland (grasses), sorghum, soybeans, strawberries, sugar cane, sweet potatoes, Swiss chard, tomatoes and turnips. A 60-day comment period from the date of publication of the risk assessment on the EPA website (expected to be before the end of December 2000) will allow concerned parties to provide input on worker and ecological risk mitigation.

The manufacturers of the technical product for Canada, Novartis and Makhteshim, who are involved in the U.S. voluntary cancellation, have indicated that they would be willing to take the same kind of voluntary action in Canada. This action would impact on all Domestic Class Products and certain uses of Commercial Class products.

The Pest Management Regulatory Agency is coming to the completion of the risk assessment of diazinon. The Agency will be studying the details of the U.S. voluntary cancellation agreement and will be determining whether the actions being taken in the U.S. will provide adequate safeguards under Canadian conditions of use.
