First report of Alternaria tenuissima causing brown spot disease of kiwifruit foliage in China
Plant Disease 103 (3), 582-582
Abstract: During 2017, kiwifruit plants (Actinidia spp.) grown in the provinces of Guizhou and Zhejiang were observed with symptoms of a brown leaf spot disease. The disease incidence averaged 25%. Early symptoms consisted of small, circular to oval, light brown to dark brown, necrotic lesions with a diameter ranging from <1 up to 8 mm. The spots gradually became round or irregular, uniformly distributed on leaves. The fungus Alternaria tenuissima 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.
