Damaging nematode affecting rice crops and strawberry production in warmer climates; could potentially present a threat to strawberry production and ornamental production in protected environments. But modern production practices seem to reduce likelihood of impacts. Pest is also regulated at EU level; which reduces likelihood of entry.

Regulated pest already subject to review at the EU level (2013). Regularly intercepted in the trade.
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.
