'Pest Alerts' is maintained by the Secretariat of the European and Mediterranean Plant Protection Organization (EPPO) and its aim is to share information collected on the Internet on new plant pests.
EPPO is an intergovernmental organization created in 1951 which currently has 50 member countries. EPPO is responsible for harmonization and cooperation among the National Plant Protection Organizations (official authorities) of its member countries. EPPO helps its members in their efforts to protect plant health in agriculture, forestry and the uncultivated environment (standard-setting activities and exchange of information).
On its official website, EPPO also provides: - the EPPO Alert List (early warning on emerging pests which could present a risk for the Euro-Mediterranean region): - a free database (PQR) on the host plants and geographical distribution of regulated pests: - the EPPO Reporting Service (a free monthly newsletter on pests and diseases):

The Canadian Food Inspection Agency (CFIA) reported that apple proliferation phytoplasma was detected in an apple orchard near Kentville, Nova Scotia. The affected orchard has been placed under quarantine. This is the first detection of apple proliferation phytoplasma in North America. A “Pacific Gala” apple orchard in the area was placed under quarantine after apple proliferation phytoplasma was detected there. The trees originated in the United States and were shipped to Canada in 2008.

Ophiomyia kwansonis is a leafminer of Hemerocallis species (daylilies) which until recently was only known to occur in Japan and Taiwan. In 2011, it was introduced into the USA where it spread rapidly. The same year, it was detected for the first time in Europe, in Slovenia. Considering the invasive behaviour of this new daylily leafminer, the EPPO Secretariat decided to add O. kwansonis to the EPPO Alert List. Delete the scoop?

A fungal [sic] plant disease was identified on the Roaches, a beauty spot in the Staffordshire area of the national park, in 2011 that killed bilberry in some areas. The disease – called Phytophthora pseudosyringae – is harmless to humans and animals but can be spread to other plants on human clothing and the coats of animals. The Roaches remains open to the public but people are asked to avoid contact with bilberry by staying on the footpaths when walking and accessing climbing crags and boulders, and to keep dogs on a short lead. This will help reduce the risk of the disease spreading further. Monitoring in 2011 and 2012 indicated some spread of the disease on the estate but the majority of bilberry plants have remained healthy. Bilberry is one of the main moorland shrubs on the estate and there were concerns the infection could spread to other moorland sites.

Anne-Sophie Roy's insight:
‘Syndrome des basses richesses’ is an emerging disease of sugar beet (Beta vulgaris). It is associated with a γ-proteobacterium ‘Candidatus Arsenophonus phytopathogenicus’ and transmitted by a planthopper, Pentastiridius leporinus (Hemiptera: Cixiidae). This disease was first found in Eastern France in 1991 but its etiology remained uncertain for a long period. Syndrome des basses richesses causes a reduction in the sugar content at the time of harvest, thus leading to significant economic losses for growers. Because this syndrome has recently been detected in Germany, the Panel on Phytosanitary measures decided to add it to the EPPO Alert List. Delete the scoop?
