The European Commission has published a inclination of 20 regulated quarantine pestilence modify as priority pest , including Xylella fastidiosa , the Japanesebeetle , the Asiatic long - horn mallet , Citrus greening and Citrus Black Spot , whose economical , environmental and social encroachment on EU ’s territory is the most spartan . Member States will have to set up information campaigns to the world , do one-year surveys , prepare contingency plans , feigning exercises , and action plans for the eradication of these pests .

Welcoming the borrowing of this tilt , Commissioner Vytenis Andriukaitis , in charge of Health and Food Safety , enounce : “ Plant wellness has been gamey on the agenda of my mandate over the past five year . This is why I am peculiarly glad to count in my legacy this prioritisation that will help the EU and Member States to increase preparedness and early actions against very dangerous plant pest and bestow to the European green deal , protect our biodiversity , the natural ecosystem and the EU agriculture . ”

Tibor Navracsics , Commissioner for Education , Culture , Youth and Sport , responsible for the Joint Research Centre , said : “ To   effectively protect our plants   and our citizens ' timbre of life , we first need to   capture the harmful wallop of pests like   the Japanese beetle or the citrus dim spot on our thriftiness , surroundings and gild . Thanks to a new indicator designed by the Joint Research Centre , we can now estimate the harm   triggered by   these pests across several dimensions , including less tangible   ones , such as landscape painting and cultural heritage   or   biodiversity and ecosystem . This   has enabled   us to identify the 20 worst wrongdoer we should focus our efforts on . "

The new methodology show up for exercise that the bacterium Xylella fastidiosa , the pest with the highest impact on farming crops , include fruit , could do one-year production losses of € 5.5 billion , sham 70 % of the EU production time value of older European olive tree trees ( over 30 long time onetime ) and 35 % value of younger one , in a scenario of the bacterium propagate across the entire EU . In addition to lineal wallop on product , pestis have substantial indirect effects on a wide range of upstream or downstream economical sector . For example , should the Asiatic long - horned mallet ( Anoplophora glabripennis ) spread across the entire EU , this could leave in the direct loss of over 5 % of the overall growing stock of several EU forestry tree diagram species , such as alder tree , ash , beech , birch , elm , maple or plane trees . These Tree are valued at € 24 billion and the economical impact on the upstream forestry sector could amount to € 50 billion .
