Fungicide review protocols critiqued



Craig Hunter, who has spent a lifetime working with farmers and the pesticides industry on plant protection products, is calling on the federal Pest Management Review Agency to change its protocols for reviewing the registrations for a group of fungicides.

He is urging the agency to do a much better job of consulting with growers, right from sharing the data in its files to checking what they are actually using on their crops and how.

He warns the agency that using models, rather than actual results gathered in the field, and that will mislead the regulators to be too restrictive about fungicide uses.

He also notes that there have been times when water samples taken after a pesticide spill have been used as the basis for restricting controlled commercial spraying of crops that’s done in compliance with regulations.

Hunter has outlined his concerns in a column he has written in The Grower, a newspaper for Ontario fruit and vegetable growers.

He argues that it’s important for the federal agency. which is part of Health Canada, to get this regulatory review right because lessons learned this time can serve to improve reviews of other pesticides in the future.

The fungicides under review are crucial to fruit and vegetable growers. They include Bravo, sold as Echo, captan, sold as Maestro, Rovral, Thiram, Ferbam, Ziram, Polyram, and mancozeb.
