【 摘 要 】

During the productive stage of Corylus avellana (hazelnut) in La Araucanía,Chile (October-December 2018-19) we observed symptoms consisting of abrown-greyish spot occurring at the bottom of the nut and enlargingupwards to the apex, and affecting around 30% of plants, mainly cv.Barcelona (Figs. 1-2). In severe infections the bracts were also affected.Symptoms were consistent with grey necrosis reported in hazelnut in Italy,and caused by a fungal complex formed mainly by Alternaria spp.,Diaporthe spp.and Fusarium spp. (Belisario et al., 2009).
