On preparation for timely detection of Xylella fastidiosa in Croatia

A plant pathogenic bacterium Xylella fastidiosa (Wells & Raju) is emerging in Europe, thus posing a growing threat for major agricultural production in certain areas especially in the Mediterranean, where Croatia is located. The bacterium is widespread in Americas on different hosts, but in 2013 it was first found in Italy in Puglia region causing extensive quick decline of olives. Still, in the EU the bacterium is quarantine pest and it is under a strict regulation. In the Republic of Croatia olive and grapevine growing represent not only deep tradition, but a prominent and strategical economic branch, even though both plants are major hosts for supervenient bacterial pathogen. In this contribution we summarize available data on preventive efforts on the national level and report approaches of preparation activities for early detection of X. fastidiosa potential outbreak in risky coastal areas of Croatia. Activities on the subject included improvements in laboratory detection, potential vectors survey and visual inspections focused on plants suffering from leaf scorch and symptoms of decline. Samplings were followed by laboratory testing on series of host plants. During last three consecutive years the high importance was given to preparation of experts and collaborating phytosanitary personnel, growers as well as on increasing public awareness. The review of continuous surveys performed by different participants in order to spot the possible occurrence of X. fastidiosa caused diseases is presented.
