We have set six principles to guide plant health practice across the Society.
There has been an increase in the rate at which harmful plant pests and diseases have become established in the UK. Diseases such as ash dieback and those caused by Phytophthora, and pests such as box tree moth and horse chestnut leaf miner are causing significant changes to our landscape and horticultural practices.
The risk of new plant pests and diseases being introduced is associated with the long-term trend of increasing volume and speed of movement of traded plants, and other material, imported from an expanding variety of sources. These risks were considered by the Government’s Tree Health and Plant Biosecurity Expert Taskforce which recommended actions to mitigate them and the Government’s approach to plant biosecurity is set out in Protecting Plant Health: A Plant Biosecurity Strategy for Great Britain.
As a result of these increased plant health risks, we have revised our approach to plant health. We have written a statement and action points for industry and policymakers on biosecurity and Brexit and have implemented the following six principles which guide plant health practice across the Society.
To implement these principles we will make a number of changes to our horticultural, retail and shows activities.
The changes will be a process of continuous improvement with some practices already implemented, some being adopted within a matter of months (e.g. providing advice to non-members on exotic pests and diseases) and others being implemented over a longer period (e.g. holding imported trees in isolation prior to use in RHS Shows).
