Exclusion
- Create physical barriers to exclude pests. -
- Clean mechanical equipment to prevent the spread of soil-borne pests and pathogens -
- Make sure all stock you receive is clean in order to exclude pests and pathogens. Create an isolation area to store new stock. - *
- Plants collected from the wild could carry pests and pathogens. Self-propagation of new plants can prevent introductions. - *
- Visually inspect all incoming stock; Inspect before shipping and upon receiving shipments. - *
- Monitor high risk plants on borders and be aware of nearby nursery pest status - *
- Treat plant wounds to prevent infection/infestation. Pretreat plants before taking cuttings -
- Training is available for many pests and diseases which will help employees recognize and manage problems -
Trapping and Monitoring
Minimizing Spread
- Isolate infested plant material -
- Remove and destroy infested/diseased nursery stock -
- Remove potential hosts from the landscape -
- Wash and/or sanitize shoes, equipment, and hands after entering an infected area -
