Mosaico e giallume del castagno: due problematiche da non sottovalutare

In the last years, the Polytechnic University of Marche together with the Edmund Mach Foundation carried out phytosanitary monitoring in some Italian regions to study the main causes of chromatic alterations in the leaves of young and secular chestnut trees. Two main symptoms, described as chestnut mosaic disease and yellowish, have been defined. These studies currently aim to assess the presence of these symptoms in Italian chestnut orchards and old plantations to evaluate their relative spread and danger. At the same time, the potential environmental factors involved in these diseases are investigated to highlight the best plant management to limit the possible damages. The Chestnut R&D Center -Piedmont is collaborating with the research team to improve controls on raw material intended for the new chestnut voluntary nursery certification.

Nel corso degli ultimi anni, in seguito alle segnalazioni dei castanicoltori, l’Università Politecnica delle Marche insieme alla Fondazione Edmund Mach sta portando avanti un monitoraggio fitosanitario in alcune regioni italiane (Marche, Emilia-Romagna, Toscana e Trentino – Alto Adige) per meglio comprendere le cause che determinano improvvise alterazioni cromatiche della chioma di castagni giovani ma anche secolari. Sono stati definiti due quadri sintomatologici, descritti rispettivamente come mosaico e giallume del castagno.
