Invasive Pests & Pathogens: What Can We Do?
Speaker: Lin Schmale, Society of American Florists
The movement of invasive pests and pathogens is a global problem as expanded trade tends to increase the spread of pests and pathogens. Quarantines often penalize our domestic growers and sometimes fail in their protection goal. Simple border inspection is not usually adequate to prevent introductions. Improved diagnostic tools can help, and moving to a "systems approach" can be effective, particularly in combination with a true clean stock program.
