Molecular characterization of Fusarium solani causing stem and root rot disease of balloon flower (Platycodon grandiflorus) in Viet Nam
Abstract The most significant issue affecting balloon flower (Platycodon grandiflorus) in Vietnam’s mountainous provinces is stem and root rot disease. The purpose of this study was to identify the causal fungus Fusarium solani of balloon flower planted in Lao Cai province. F. solani’s identity was confirmed through DNA sequencing and phylogenetic analyses based on ITS sequences. PDA was the most suitable medium for F. solani growth and development of the three semi-solid media tested (CA, PDA, and CDA). The optimal temperature and pH conditions for its growth ranged from 25-30 °C with a maximum growth rate of 25 °C and pH 5.5-7.0 with a maximum growth rate of 6.5. This is the first report of F. solani causing balloon flower stem and root rot in Vietnam.
期刊介绍：
Archives of Phytopathology and Plant Protection publishes original papers and reviews covering all scientific aspects of modern plant protection. Subjects include phytopathological virology, bacteriology, mycology, herbal studies and applied nematology and entomology as well as strategies and tactics of protecting crop plants and stocks of crop products against diseases. The journal provides a permanent forum for discussion of questions relating to the influence of plant protection measures on soil, water and air quality and on the fauna and flora, as well as to their interdependence in ecosystems of cultivated and neighbouring areas.
