Diseases of Gypsophila
G. paniculata L (“baby’s breath”) is a worldwide crop mainly used as a filler cut flower. It is commercially propagated vegetatively to preserve the ornamental characteristics of the plant. Among fungal diseases caused by soilborne pathogens, Phytophthora species and Rhizoctonia solani, due to their irreversible rotting of plants, are the most devastating Gypsophila disease worldwide. Pythium species and R. solani are especially destructive in the process of rooting cuttings. In adult plants, Fusarium species produce rotting of basal tissues resulting in death. Powdery mildew caused by Erysiphe buhrii is important on aerial parts, producing in some countries nearly 100 % of disease incidence at harvest. Crown gall has been reported in all continents, and few viruses and nematodes are cited.
