First report of Gnomoniopsis smithogilvyi causing chestnut brown rot on nuts and burrs of sweet chestnut in Spain
Plant Disease 107 (1), 218-218
Abstract: During 2021, sweet chestnut trees (Castanea sativa) grown in Spain were observed with symptoms of premature fall of burrs and nuts. The green burrs had turned brown and fallen off, and the nuts showed brown lesions in kernels and embryos. Some nuts had become mummified. The fungus Gnomoniopsis smithogilvyi 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.
