A plant germ found in Europe for the first time is killing off centuries-old olive trees in southern Italy’s Apulia region, and researchers have not yet figured out how far the pathogen has spread.

Scientists found Xylella fastidiosa, a bacterium native to the Americas, in plants across Lecce province in Apulia’s south, said Anna Maria D’Onghia, head of integrated pest management at the Mediterranean Agronomic Institute of Bari.

The institute is testing plants without signs of infection to determine a protective buffer zone. The germ may have been introduced via the import of ornamental plants, according to D’Onghia.

“We are researching how far the pathogen has moved from this area. Usually when you see the diseased trees it’s too late,” D’Onghia said.

Italy’s agriculture ministry said it was setting up a task force to determine the boundaries of the infected areas and develop a plan to prevent further spread.

一種首度在歐洲發現的植物細菌,正在消滅義大利南方阿普里亞地區有數世紀之久的橄欖樹,研究人員還無法測出病原已經傳播到多遠的地方。

科學家們在遍佈阿普里亞南部萊切省的植物中,發現一種原產於美洲大陸的細菌「木質部難養菌」,巴里的地中海農藝學院害蟲整合管理負責人安娜.瑪莉亞.朵西亞說。

該學院正在測試沒有感染跡象的植物,以劃定一個保護緩衝區。這種細菌也許是經由進口觀賞植物所輸入,朵西亞說。

「我們正在研究這種病原已從這個地區傳到多遠的地方。」通常當你看到病樹時,已經太晚了,朵西亞說。

義大利農業部說,正籌組專案小組以確認受感染區域的範圍,並研擬一套計畫阻止病菌進一步傳播。
