NEW DISEASES OF WILD AND CULTIVATED ROCKET IN ITALY
During the past ten years several diseases caused by soil-borne and foliar pathogens were observed for the first time in Italy on wild (Diplotaxis tenuifolia) and cultivated (Eruca sativa) rocket grown in intensive cropping systems for fresh cut production. This sector is particularly exposed to the risk of the emergence of new diseases as a consequence of its dynamism, specialization and use of intensive cultivation techniques. Two Fusarium wilts have been observed in Italy on wild and cultivated rocket. Among soil-borne pathogens, attacks of Rhizoctonia solani, and Pythium spp. were increasingly observed. Among foliar diseases, downy mildew of wild rocket and a leaf spot of wild and cultivated rocket caused by Alternaria japonica were recently observed. A new leaf spots caused by Fusarium equiseti, was observed for the first time in the world on Eruca sativa. During spring 2012, symptoms of an unusual leaf spot caused by Plectosphaerella cucumerina were observed in several commercial greenhouses near Salerno (southern Italy) on plants of D. tenuifolia. The biology, epidemiology, physiological characteristics of the causal agents are reported.
