Abstract:
Root rot disease is vital disease of Coptis chinensis, it has bursted in most producing area in recent years, and has caused severe damage. To identify the pathogenic fungi, Fusarium spp. fungi were isolated from rot root, of which the pathogenic fungi were screened with inoculation on C. chinensis root and plant, and identified with molecular and morphological method. The 20 Fusarium spp. fungi were obtained, of which 5 displayed high pathogenicity. It was deduced that F. oxysporum, F. solani and F. tricinctum were the pathogen, possibly pioneer pathogen of C. chinensis root rot disease. Among which F. oxysporum was dominant and deserved to pay more attention. High temperature and high humidity can increase pathogenicity of Fusarium spp. So the global climate warming may lead to temperature rising of C. chinensis producing area and favor the pathogen fungi, which may be one of the main factors leading to bursting of C. chinensis root rot disease. To control the root rot, beside developing and using pesticide, producing base should be moved to a high altitude area.
