Eradication and containment action required against findings of Phytophthora ramorum and Phytophthora kernoviae
The following eradication and containment action will be required under official notice against all findings of Phytophthora ramorum. Similar measures will also be required against all findings of Phytophthora kernoviae.
Nurseries and retail premises
- Destruction by burning or deep burial (infected plants, susceptible plants within a 2m radius of infected plants and associated plant debris).
- Disinfection of surfaces.
- Disinfection of pots.
- Prohibition on movement of susceptible plants within a 10 m radius of infected plants and remaining plants in infected lot for at least 3 months.
- Prohibition on use of Phytophthora fungicides during the holding period.
- Advise the cessation of overhead irrigation.
- Trace-back and trace-forward of related plant material.
- An intensive inspection regime involving fortnightly visual inspections, quarterly random sampling of susceptible hosts and quaterly water baiting.
Parks, gardens and uncultivated land
- Prohibition on movement of the infected plant and parts of the plant (e.g. must not be used for propagation purposes or foliage purposes).
- Destruction by burning or deep burial (infected plants, susceptible plants within an appropriate cordon sanitaire and associated plant debris). No planting of susceptible hosts within 4m for 3 years.
- Prevention of regrowth.
- For infected trees, felling or pruning will be required depending on the part of the tree infected and the extent of infection.
- Measures must be taken to prevent re-infection at the site (e.g. prohibition on planting susceptible plants in contaminated soil, removal or sterilisation of contaminated soil).
- A protocol of biodiversity measures specific to each site.
- A regular programme of surveillance.
