Guidance for people working in Phytophthora-infected woodland or working with wood from Phytophthora-infected trees.
When operations are taking place in woodlands confirmed as having either Phytophthora ramorum and/or P. kernoviae, best practice includes general hygiene precautions. This applies to all potentially damaging pests and diseases.
- Ensure staff are aware of this guidance
- Carry recommended bio-security equipment when visiting infected woodland.
- If you come into contact with infected larch or rhododendron ensure that before leaving the site, footwear, tools, equipment, plant and machinery are free from any soil and plant debris. Because this is common practice when moving machinery from site to site via main roads, it is suggested that it is also extended to all movements of plant, machinery tools and equipment within the forest boundary. This should be achieved by simple brushing to remove as much soil and plant debris as is reasonably practicable.
- In areas where either P. ramorum or P. kernoviae is detected, a statutory Plant Health Notice will impose measures including, in addition to the above, disinfection with an appropriate fungicide.
- Management of larch stands after removal should take account of the future impacts of infection by Heterobasidion annosum fungus.
Guidance and advice
Financial support for owners and managers
In England, some support for landowners is available under Countryside Stewardship in response to tree health issues. Information is provided within the following two capital item guides:
In Scotland, grants are available for landowners to assist with the provision of services from qualified agents to give advice about dealing with the infected area and, possibly, organise clearance work. Grants are also available to assist with the costs of tree clearance.
