First report of stalk bacterial soft rot of sugarcane caused by Dickeya zeae in China.
In late September 2019, seven stalks from approximately 1400 stalks of sugarcane cultivar Zhongzhe 1 exhibited soft rot symptoms in a trial plot in Beihai city, Guangxi province, China. Symptoms included scorched and collapsed leaves, maceration of stalks, and sour-smelling exudates from the stalks. Severely diseased stalks had collapsed and were dead. The causal pathogen was isolated and identified as Dickeya zeae based on molecular and pathogenicity analyses. This is thought to be the first report of a bacterial stalk rot caused by D. zeae in sugarcane.
