EPPO Alert List
(last updated in 2010-01)
The purpose of the Alert List is to draw the attention of EPPO member countries to certain pests possibly presenting a risk to them and achieve early warning. Pests are marked with an asterisk* in the Table below when PRAs are planned or under development within EPPO. The entry date corresponds to the date when the pest was added to the Alert List.
Read a short introduction on the purpose and maintenance of the EPPO Alert List.

As explained in the introduction, after a certain period, if it appears that the risk is no so high and that no special phytosanitary action is needed, the pests are deleted from the Alert List. On the opposite, when the risk is considered sufficiently high, pests are transferred to the EPPO A1 or A2 Lists and on the Action List.
