Plant Health and Pesticides

Plant Health

Dahlia (1000px * 750px)Growers in Wales have to tackle a huge variety of plant pests and diseases, many of which could cause significant crop damage if they were to become established here.

To prevent these potentially harmful pests spreading, a number of official controls, legislation, and restrictions on the import, movement, and keeping of specific plants, pests, and materials such as soil are in place. However, rules and regulations simply aren’t enough – protecting plant health needs to be a joint effort between the various government agencies or departments, growers and retailers across the horticulture sector, and the wider public too.

Here in Wales, responsibility for enforcing plant health policy lies with the Plant Health and Seeds Inspectorate, which falls under the jurisdiction of APHA (Animal and Plant Health Agency), an executive agency of DEFRA.

Tree Disease

With the increased global movement of plants, it is inevitable that the UK has to contend with the new spread of pests and diseases. Trees, forests, and woodlands are under greater threat from diseases such as Phytophthora ramorum and Chalara fraxinea, with a number of rules, restrictions, and policies put in place to mitigate these risks.
