Health Canada (HC) and Agriculture and Agri-Food Canada's (AAFC) Pesticide Risk Reduction Program identified greenhouse vegetables as a priority crop. General greenhouse vegetable production information and issues along with pest issues are documented in the greenhouse vegetable crop profiles for cucumber, lettuce, pepper and tomato). Greenhouse vegetables issues documents, extracted from the crop profiles, were used as discussion tools in stakeholder meetings and consultations to help identify the top insect, disease and weed issues. General issues of concern and potential solutions to these issues are also discussed at these meetings. AAC's Pest Management Centre prepared both documents in consultation with the greenhouse vegetable industry, the Pesticide Risk Reduction Program's Technical Working Group and the Pest Management Regulatory Agency (PMRA).
An Eastern greenhouse vegetable stakeholder meeting was held July 20, 2005, in Ruthven, Ontario, to prioritize issues, identify possible solutions and propose members for a national steering committee. Participants included Ontario growers, provincial specialists, researchers, the pesticide industry, greenhouse consultants, the biological control industry and federal government representatives (Pest Management Centre, PMRA and Canadian Food Inspection Agency).
A greenhouse lettuce grower, representatives from the ministère de l'Agriculture, des Pêcheries et de l'Alimentation du Québec the Pest Management Centre and the PMRA met on September 8, 2005, to discuss issues and potential solutions that are relevant to the greenhouse vegetable industry in Quebec. Several representatives from ministère de l'Agriculture, des Pêcheries et de l'Alimentation du Québec, biological control companies and consultants met on November 21, 2005, to discuss the same items.
A Western greenhouse vegetable stakeholder meeting was held September 21, 2005, in Abbotsford, British Columbia, to prioritize issues, identify possible solutions and propose members for a national steering committee. Participants included growers from Alberta and British Columbia, provincial specialists, researchers, the pesticide industry, consultants and the federal government. Although lettuce growers from Quebec were not able to attend this meeting, their issues were discussed in the lettuce breakout group.
The national steering committee is comprised of greenhouse vegetable growers from various province (Alberta, British Columbia, Ontario and Quebec), grower association representatives, provincial specialists, scientists (pathologists and entomologists), a representative from AAC's Pest Management Centre and the PMRA. The steering committee identified mites (two-spotted, carmine, tomato russet, broad and cyclamen), loopers, powdery mildew, thrips, Fusarium and whitefly as their top pest issues (April 11, 2006). A working group was set up to develop a strategy to address each of the issues.
The Pesticide Risk Reduction Program has funded several projects addressing the priorities the Greenhouse Vegetables Working Group established in consultation with the Pest Management Centre and the PMRA.
