First report of leaf spot of radicchio in Egypt caused by Alternaria cichorii.

Abstract

During 2012, a foliar disease of commercially grown radicchio (Cichoriumintybus cv.) was observed in commercial farming regions of El-Khatatba, Egypt at an estimated incidence of 21% of plants. Symptoms included necrotic spots on leaves, with each spot ranging in diameter from 5 to 25 mm and developing concentric zones of dark tissue. This is the first report of A. cichorii causing a leaf spot on commercially grown radicchio in Egypt.
