A DIEBACK OF HAZELNUT (CORYLUS AVELLANA L.) IN THE NORTH OF LATIUM: ETIOLOGY AND CONTROL

L. VARVARO
A decay of hazelnuts was observed in a central area of Italy (northern Latium). During the summer, leaves shriveled and became dark-red in a few days. The infected branches died suddenly and their withered leaves remained attached, even after the leaf fall in autumn. On the basis of morphological, biochemical, physiological and pathogenicity tests, the etiological agent has been identified as a bacterium belonging to 'true erwiniae group' and very close to Erwinia amylovora and E. rubrifaciens. At present the possibilities of controlling this disease consist in preventive measures.
