Because they are open to the public, botanical gardens are at risk of damage from SOD and other diseases and pests. Find out how you can prevent introduction of these organisms and what to do if they get in:
These documents from the UK National Trust have information that will also apply to public gardens in the US and Canada:
Guidance for visitors on how to help us protect the garden from introduced pests and diseases

2a. Handling brought-in plants and quarantine areas – general advice
3. Use of Phytophthora lateral flow devices (LFD)
4. Cleaning footwear and hands
5. Managing gardens to reduce the risk of pests and diseases
This poster illustrates best management practices for preventing disease and pest problems in gardens and nurseries. It can be posted in a break room or other common area to educate workers, volunteers, and others. Available in English and Spanish versions.

Many thanks to Ian Wright, The National Trust, for providing the information on this webpage.
National Trust is a UK charity formed over 100 years ago to protect places of Historic Interest or Natural Beauty, for ever for everyone.
It now manages 1 million acres of countryside, 600 miles of Coastline, 240 Buildings of Historic importance and 220 historic gardens and parks (covering 35,600 acres in England, Wales and Northern Ireland. The National Trust is financially supported by membership subscriptions, donations and visitor income.
Over 3.5 million people are members of the National Trust. 12 million people visit our gardens each year. Over 700 plants have been raised, bred or named at our gardens. Our gardens span over 700 years of garden history and plant collecting.
Phytophthora can cause substantial problems for nurseries because they are challenging to manage and some species are heavily regulated. Therefore, the aim of this webpage is to provide information and resources to help you keep Phytophthora ramorum and other diseases out of your nursery.
Here you will find information about Best Management Practices and resources produced specifically for managing plant pathogens in nurseries. Note that many of these practices can be applied to control or prevent the establishment of a variety of plant pathogens.

General information for nursery production
Contact us for a Critical Control Point Assessment. We can visit your production and provide recommendations for best management practices suited to your nursery or garden.
Management of P. ramorum in nurseries
There are four Critical Control Points to prevent the entry of waterborne diseases such as Phytophthora and Pythium into your production:
By preventing or managing diseases at these points, you can minimize the damage and loss of product, and grow clean, healthy plants.

Phytophthora diseases
Welcome to the WSU Puyallup Ornamental Plant Pathology program. We are part of the Department of Plant Pathology and based in the WSU Puyallup Research and Extension Center.
The purpose of this website is to share information and resources about managing diseases of ornamental and native plants in Washington State. Please explore our website to learn more about our research and extension programs.
Spring 2023
Winter 2023
Autumn 2022
Much of our research is focused on reducing the impacts of pests and diseases on industries involved in the trade of ornamental bulbs, lavender, and Christmas trees. We also conduct applied research to increase the post harvest longevity of Christmas trees.
Our program also conducts research about diseases caused by Phytophthora (fy-toff-thor-uh) species. For example, we work closely with federal and state agencies to manage and monitor Phytophthora ramorum, the invasive species that causes Sudden Oak Death and ramorum foliar blight. We also conduct research about diseases such as Pacific madrone leaf blight and Dutch Elm Disease.
Major aims of our Sudden Oak Death Research Program are to serve stakeholders in the state of Washington with:
Our program has summarized a few plant health concerns that have emerged recently. Access information about these plant health issues by clicking on the images below.
We will continue to update this section of our website. Please feel free to contact us if there are other emerging issues that you would like more information about.
Sooty Bark Disease is an emerging concern in the Seattle metropolitan area. Find out more about this emerging concern here.
Interested in advancing knowledge and developing solutions to plant health issues in the Pacific Northwest? Our program currently hosts two citizen science projects that anyone can participate in.
Citizen science is a term for research projects that involve the general public in data collection. Visit our citizen science webpage to learn more about the current opportunities to contribute to our research.
Visit our jobs page to find out more about the opportunities to join the Ornamental Plant Pathology research program.
Check back frequently as we have many projects with seasonal opportunities.
Support our program to help us conduct research and provide more services for Washington’s residents and industries through tax-deductible gifts to WSU.
