Phytoplasma which potentially affects a wide host range; determined by the feeding behaviour of vectors. First UK outbreak in 2014; on strawberry; a host not specifically regulated in EU legislation. This legislation should be reviewed to take account of this and other developments.

Defra's Risk register #3

Plant name

Solanum tuberosum 'Rooster' (Potato 'Rooster')

Common pest name

Apple root knot nematode

Scientific pest name

Meloidogyne mali

Type

Nematode

Current status in UK

Unknown

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

3

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

4

General biosecurity comments

UK (along with certain other European countries) received potentially infested trees in 1992; but these were destroyed at the end of the trial period and targeted surveillance has failed to find any trace of the nematode. Main impacts are on elm; apple and mulberry and industry should source such material carefully.

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.
