Olive trees in Europe have been hit by a deadly disease for which there is no cure

Tridge summary

A study estimates the economic impact of the Xylella fastidiosa pathogen, which has been affecting olive trees in Europe, particularly in Italy, could exceed €20 billion. The bacterium, transmitted by insects, has the potential to impact olive plantations in Spain and Greece, potentially leading to a increase in the cost of olive oil for consumers. The current scenario in Italy has resulted in a 60% drop in yields since 2013, causing significant damage to the local economy and tourism. The researchers suggest that the cost could be reduced if resistant varieties are planted and the infection rate is controlled.

The economic costs of a deadly pathogen affecting olive trees in Europe could reach more than €20 billion, researchers say. They modeled the future worst effects of the pathogen Xylella fastidiosa, which has killed many trees in Italy. Spread by insects, the bacterium now poses a potential threat to olive plantations in Spain and Greece. The disease may increase the cost of olive oil to consumers. This is reported by the BBC. Xylella is considered one of the most dangerous plant pathogens worldwide. There is currently no cure for the infection. It can infect cherry, almond and plum trees, as well as olives. It became closely associated with olives after the strain was discovered on trees in Puglia, Italy, in 2013. The microorganism is transmitted by insects that suck the juice, such as beetles. The infection limits the tree's ability to move water and nutrients, and over time it wilts and dies. Plants infected with the bacteria must be destroyed to prevent the spread. Follow the ...
