Survey of Pest Problems and Pesticide Use in Canadian Forest Seedling Nurseries

A survey regarding pest problems and pesticide use was distributed to forest seedling nurseries across Canada in the spring of 2017. Growers were asked to volunteer information relevant to their site for the pests found and the pesticides applied over the previous 5 years. Botrytis gray mold was identified as the main disease of concern, requiring at least one pesticide application over the previous 5 years at 89 percent of nurseries. Fusarium root rot is also a disease of concern. The survey identified Lygus bug as the main insect problem and liverwort as the main weed problem. The results highlight the need for new pesticide registrations for forest seedling nurseries in Canada. A full summary of the survey methodology and findings are reported. This paper was presented at the 2019 Joint Annual Meeting of the Forest Nursery Association of British Columbia and the Western Forest and Conservation Nursery Associations (Sydney, British Columbia, September 30–October 2).
