Xylella fastidiosa detected for the first time on olive trees in Argentina
In October 2014, the presence of Xylella fastidiosa (EPPO A1 List) was reported in olive trees (Olea europaea cv. ‘Arauco’) in the areas of Aimogasta (La Rioja) and Cruz del Eje (Córdoba) in Argentina. Out of 50 tested plants, half of them were found to be infected with the bacterium. Symptoms of leaf scorch have been observed in affected plants. Surveys will be carried out in Argentina to determine the extent of the disease and its vectors. This is the first time that X. fastidiosa is detected on olive trees in Argentina. Previously, the bacterium had only been detected in plum (Prunus domestica), almond (P. dulcis) and citrus trees.
