The Plant Health Assurance Scheme (PHAS)

In response to the critical threat posed by Xylella Fastidiosa and other plant health risks, HTA and our partners are developing the PHAS. It is being designed to mitigate, protect, and potentially compensate horticulture businesses from the risks posed by a serious plant health incident. 

Scheme status

The PHAS is designed as a standard (audited by inspection) that can be applied to a business' operating processes and procedures. The standard is being piloted in several businesses and an evaluation is underway. 

We are currently conducting a consultation on the format of the scheme and working on the pricing model with a view to making it as affordable as possible. Given the risks some pests and diseases pose to the natural landscape we are liaising with Defra over possible funding for the scheme.
