First Report of Fusarium avenaceum Causing Blight on Juniperus formosana in China: Morphological and Molecular Characterization

In October 2024, a large-scale blight was found on tender shoots (young green shoots) of <i>Juniperus formosana</i> in Kaili City, Guizhou Province, China. The pathogen was isolated and purified from the diseased tissues by the tissue isolation technique. Through ITS identification and microscopic examination, the pathogen was determined to be <i>Fusarium avenaceum</i>. This is the first discovery in China that the blight on <i>Juniperus formosana</i> is caused by <i>Fusarium avenaceum.</i>
