Capparis spinosa - a new host for Sclerotium rolfsii.

Abstract

In June 2005, wilting of C. spinosa plants was observed in 3 fields in Sicily, Italy, with up to 30% of plants in each field affected on between one and five branches, and whitish mycelium and rotting tissue often present at the base of the affected shoots. In September, several plants with symptoms were observed at almost all the locations inspected. S. rolfsii [Corticium rolfsii] was isolated from infected plants, and pathogenicity tests confirmed the virulence of R. solani on C. spinosa. This is thought to be the first report of S. rolfsii on C. spinosa.
