Phomopsis and Sudden Oak Death: A Tale of Two Nursery Nuisances

Abstract

Tree nurseries, by their very nature, provide key components of the disease triangle (pathogen, host, and environment) simply by the widespread planting of susceptible host(s) grown under optimal conditions. Pathogens can severely impact the quality and quantity of seedling stock, making pest management a high priority in successful nursery practice. Careful inspections for symptoms and signs of fungal agents can improve the precision of cultural, chemical, and biological management strategies, as well as alert growers to newly emerging pests of concern. The purpose of this presentation is to highlight two such nursery nuisances and to discuss implications of their introduction, establishment, and management.
