First report of binucleate Rhizoctonia AG-L causing root and stem rot of wishbone flower (Torenia fournieri) in Taiwan
Plant Disease 105 (10 - 2428)
Abstract: During 2018, ornamental wishbone flowers (Torenia fournieri) grown in Taiwan were observed with symptoms of root and stem rot. The basal stems had a dark brown discoloration and the roots a brown necrosis. The binucleate Rhizoctonia AG-L fungus was isolated from the diseased plants. The identification was based on morphological characteristics and DNA sequence analysis. Pathogenicity of the isolates was demonstrated by inoculation and re-isolation.
