3

Impact (1 is very low - 5 is very high)

4

General biosecurity comments

A bacterial disease with a wide host range and many sub-species and strains; including those that could thrive in cooler climates; showing different levels of pathogenicity. Although EU regulated; there is some concern about the risk of introduction. Should an outbreak occur; there would be a need for eradication action which would result in environmental and social impacts.

Defra's Risk register #2

Plant name

Lilium regale (Regal lily)

Common pest name

Lance nematode; Nematode; Lance

Scientific pest name

Hoplolaimus spp.

Type

Nematode

Absent

Likelihood to spread to UK (1 is very low - 5 is very high)

2

Impact (1 is very low - 5 is very high)

4

General biosecurity comments

Nematode species potentially affecting a wide variety of crops; prohibition of soil likely to mitigate risk substantially; keep under review in light of interceptions or findings should they occur in the EU.

Defra's Risk register #3

Plant name

Lilium regale (Regal lily)

Common pest name

Scientific pest name

Plantago asiatica mosaic virus

General biosecurity comments

Pest risk analysis suggested potential economic impacts would be small; and management by industry would be appropriate. Industry may wish to monitor for the presence of the pest and the Dutch industry certification scheme is of added benefit to the UK.

About this section

Our plants are under greater threat than ever before. There is increasing movement of plants and other material traded from an increasing variety of sources. This increases the chances of exotic pests arriving with imported goods and travellers, as well as by natural means. Shoot is working with Defra to help members to do their part in preventing the introduction and spread of invasive risks.
