Abstract

This paper describes the disease symptoms observed on some ornamental grass and shrubs cultivated in gardens, public and private, in Italy. This is thought to be the first report of Erysiphe pulchra, Sphaerotheca, and Golovinomyces cichoracearum var. cichoracearum on Cornus florida, Impatiens hawkeri, and Verbascum thapsus, respectively in Italy.
