First report of Fusarium foetens causing tobacco root and stem rots in Guizhou, China
First report of Fusarium foetens causing tobacco root and stem rots in Guizhou, China
In September of 2019, root and stem rots were observed in tobacco plants in Xingren, Guizhou Province, China. Typical symptoms included rotted roots and stems, failure to form vascular bundles or complete necrosis of vascular bundle tissues, and the plant later showed hollow stems and complete wilt. In a 0.13-ha field, the disease incidence was 50%–60%, causing serious economic losses. Based on morphological characteristics and molecular identification, as well as confirmation of pathogenesis following Koch's postulates, the causal agent was identified as Fusarium foetens. To our knowledge, this study is the first report of F. foetens as a pathogen on tobacco causing root and stem rot in Guizhou, China. The identification of the pathogen could lay the basis for its sustainable management in future.

Abstract
In September of 2019, root and stem rots were observed in tobacco plants in Xingren, Guizhou Province, China. Typical symptoms included rotted roots and stems, failure to form vascular bundles or complete necrosis of vascular bundle tissues, and the plant later showed hollow stems and complete wilt. In a 0.13-ha field, the disease incidence was 50%–60%, causing serious economic losses. Based on morphological characteristics and molecular identification, as well as confirmation of pathogenesis following Koch's postulates, the causal agent was identified as Fusarium foetens. To our knowledge, this study is the first report of F. foetens as a pathogen on tobacco causing root and stem rot in Guizhou, China. The identification of the pathogen could lay the basis for its sustainable management in future.
