To investigate control of this phytopathogen, a compound containing zinc and copper complexed with citric-acid hydracids (Dentamet®) was evaluated for <em>in vitro</em> and <em>in planta</em> bactericidal activity. Confocal laser scanning microscopy, fluorescent quantification and atomic emission spectroscopy were then used to determine if the compound reached the xylem networks of leaves, twigs and branches of olive, to release zinc and copper within the xylem. A 3-year field trial in an olive orchard containing mature Cellina di Nardò and Ogliarola salentina olive trees, and officially declared infected by <em>X. fastidiosa</em> subsp. <em>pauca</em>,was also carried out o to determine if the compound affected severity of the disease. Each year, from early April to October (excluding July and August), six spray treatments of 0.5% (v:v) Dentamet® were applied on the olive tree crowns. The compound reduced severity of symptoms in both cultivars. Most untreated trees died by the end of the trial, whereas all treated trees survived with good vegetative status as assessed by a normalized difference vegetation index. Quantitative real-time PCR was performed from June 2016 to September 2017, following the official procedures established by the European and Mediterranean Plant Protection Organization. The analysis revealed a statistically significant reduction of <em>X. fastidiosa</em> cell densities within the leaves of treated trees. These promising results suggest that integrated management to reduce severity of <em>X. fastidiosa</em> that includes regular pruning and soil harrowing with spring and summer spray treatments with Dentamet®, is likely to effectively control the disease.</p> <p> </p>}, number={1}, journal={Phytopathologia Mediterranea}, author={SCORTICHINI, Marco and CHEN, Jianchi and DE CAROLI, Monica and DALESSANDRO, Giuseppe and PUCCI, Nicoletta and MODESTI, Vanessa and L’AURORA, Alessia and PETRICCIONE, Milena and ZAMPELLA, Luigi and MASTROBUONI, Francesco and MIGONI, Danilo and DEL COCO, Laura and GIRELLI, Chiara Roberta and PIACENTE, Filippo and PIACENTE, Filippo and CRISTELLA, Nicola and MARANGI, Paolo and LADDOMADA, Francesco and DI CESARE, Michele and CESARI, Gianluigi and FANIZZI, Francesco Paolo and LORETI, Stefania}, year={2018}, month={Mar.}, pages={48–72} }
