First report of Xylella on the mainland of Spain

The analysis made at the National Reference Laboratory for Phytopathogenic Bacteria of Spanish Agriculture Ministry, that is the Bacteriology Lab of Instituto Valenciano de Investigaciones Agrarias (IVIA), confirmed the results of the Plant Health Service of the “Conselleria de Agricultura, Medio Ambiente, Cambio Climático y Desarrollo Rural” of the Autonomous Community of Valencia (Spain) on the detection of Xylella fastidiosa in several trees of an almond orchard in the municipality of Guadalest, in the Marina Baixa region of Alicante Province. The subspecies of the bacterium has not been determined yet. In Spain, Xylella fastidiosa was previously detected in the Balearic Islands in November 2016, but this is the first record on the mainland Spain and Iberian Peninsula as a whole.

Statement from FEPEX, the Spanish member of ENA, received on 03-07-2017:

Xylella fastidiosa outbreak in mainland Spain

Last Friday, 29th June, the Department of Agriculture, Environment, Climate Change and Rural Development of the Valencian Community confirmed the detection of an outbreak of Xylella fastidiosa in an almond trees plantation in the Guadalest municipality (Alicante’s region). At the time of confirmation and according to EU legislation, the information was communicated to the Spanish Ministry of Agriculture and Fisheries, Food and Environment, to the Directorate-General for Health of the European Commission and to the Plant Health Services of the adjacent Autonomous Communities (Regions).

As required by the European Commission to all Member States as of December 31, 2016, the Spanish Ministry of Agriculture and Fisheries, Food and Environment, launched a Contingency Plan for Xylella fastidiosa, which is being implemented in collaboration with all Autonomous Communities (Regions). The Contingency Plan includes a specific protocol for prospecting in nurseries and garden centres for its early detection. In addition to this Plan and given the enormous importance of the citrus, fruit and olive sectors in Spain, the Ministry of Agriculture has developed, in collaboration with the Autonomous Communities, a Special Control and Surveillance Plan with the aim of reinforcing the monitoring of the traceability of all species of plants susceptible to the bacterium Xylella fastidiosa. Until now, NO SUSPICIOUS CASE HAS BEEN DETECTED IN NURSERIES OR IN HORTICULTURAL PRODUCTIONS, except for the abovementioned one.

Likewise, the Regional Ministry of Agriculture of the Valencian Community has implemented an intensive system of prospecting and analysis to determine if there are more plants infected in the vicinity of the plot, as well as in the same region and neighbouring regions. The Regional Ministry has confirmed that the olive tree samples collected in the vicinity of the infected plot have been negative.

The Ministry of Agriculture will hold a meeting of the Sectorial Table for Plant Health on 5th July to explain in more detail all the actions that are being developed in relation to the Xylella. FEPEX, as a member of the Sectorial Table, will take part in the meeting and will keep you informed.


Outbreak of Xylella in Spain: action of eradication in compliance with the Commission Implementing Decision 2015/789    

The Plant Health Authority of Comunitat Valenciana sprayed the affected orchard and others in a 100 m radius with insecticides for vector control. To comply with the Commission Implementing Decision (EU) 2015/789, all plants of listed species within the 100 m radius are being removed. Additionally, intensive surveys for X. fastidiosa are being conducted in a radius of 10 km…

Parliamentary questions - 8 June 2017    E-002644/2017 Answer given by Mr Andriukaitis on behalf of the Commission

As far as EU funding is concerned within the plant health Directive 2000/29/EC(1) and the related co-financing Regulation (EU) No 652/2014(2), grants can be given for the implementation of survey programmes and EU emergency measures. EU co-financing for compensation to owners for the value of destroyed plants might also be available, under certain conditions.

Additionally, the common agricultural policy provides for support to alleviate the negative effects of natural disasters. The operational programmes of recognised producer organisations(3) may include crisis prevention and management actions, and under the Rural Development Regulation,(4) support is provided for risk management tools, prevention and restoration actions.

Lastly, movement of specified plants as defined under Commission Implementing Decision (EU) 789/2015(5) is currently prohibited within and out of the Balearic Islands. Official checks and implementation of those provisions is a Member State responsibility.

The Commission will nevertheless proceed with an audit in June 2017 to evaluate the situation of Xylella fastidiosa and control measures as regards movement in the Spanish territory, and more particularly in the Baleares, and further follow-up actions might be considered if the situation on the ground requires so.

The other Member States are also adapting their control measures to this new situation in the Baleares. The matter is regularly discussed with all Member States in the Standing Committee on Plants, Animals, Food and Feed.
