The new rules relate to the imported Zea mays seeds (maize and sweetcorn).
The changes were made to target Maize lethal necrosis disease (MNLD). This is a disease that is increasing in distribution worldwide, and it causes severe yield losses (up to 100%) in susceptible varieties.
The new requirements came into effect on 1 December 2014.
