1974年以来在南京、江苏省溧阳县及浙江省德清县陆续发现刚竹秆褐腐病。此病主要危害刚竹Phyllostachys viridis(Young)McCl.及槽里黄刚竹Ph.virdis f.houzeauana(McCl)C.D.Chu et C.S.chao.在竹秆的基部形成紫褐色至黑褐色条状病斑,很快引起整株枯死。对病原进行了多次的分离和接种证实病原为镰刀菌Fusarium solani(Mart.)Sacc.人工接种病菌可自伤口侵入。潜育期在日平均温度22—25℃为15—20天。病菌生长的适宜温度为25—28℃,在pH4.5—10之间均能生长,孢子萌发的适宜温度为25—28℃。人工接种还可侵染毛竹ph.Pubescens Mazel ex H.de Lehaie、桂竹Ph。bambusoides sieb.et Zucc.、淡竹Ph.glauce McCl.、早竹Ph.praecox C.D.Chu et C.S.Chao、水竹Ph.heteroclada Oliv石竹Ph.nuda McCl.、红壳竹Ph.iridencens C.Y.Yao et C.Y.chen、黄古竹Ph.angusta McCl.、黄苦竹Ph.decora McCl.、紫竹Ph.nigra(Lodd.)Munro、毛金竹Ph.nigra var.henonis stapf ex Renclle及短穗竹Brachystachyum clensiflorum (Rendle)Keng
Since 1974, Nanjing, Jiangsu Province, Liyang County and Deqing County, Zhejiang Province, one after another found that rigid bamboo brown rot. The disease mainly endangered Phyllostachys viridis (Young) McCl. And Ph.virdis f.houzeauana (McCl) CDChu et CSchao, forming a purple-brown to dark brown stripe at the base of the bamboo culms, very quickly Cause the whole plant dead. Separation and inoculation of the pathogen several times confirmed that the pathogen was Fusarium solani (Mart.) Sacc. Inoculated pathogens invade the wound. The incubation period at a daily average temperature of 22-25 ℃ for 15-20 days. The optimal temperature for germ growth is 25-28 ℃, which can grow at pH4.5-10. The suitable spore germination temperature is 25-28 ℃. Artificial inoculation can also invade the bamboo ph.Pubescens Mazel ex H.de Lehaie, Phyllostachys Ph. bambusoides sieb.et Zucc, Ph.glauce McCl., Ph.praecox CDChu et CSChao, Ph.nteroclada Oliv, Ph.nuda McCl., Ph.iridencens CYYao et CYchen, Ph.angusta McCl., Ph.decora McCl., Ph.nigra (Lodd.)
