Abstract:
Root rot disease restricts the Coptis chinensis industry in Shizhu of Sichuan province. To disclose fungi composition and pathogen in rot root,so as to prevent and treat the root rot disease,the C. chinensis rot root of 5 years from 4 areas in Shizhu were collected in 3 seasons respectively. The fungi were isolated and molecularly and morphological identified,followed with population statistics. 437 fungi were isolated,belonging to 5 subphylum,11 classes,16 orders,22 families and 28 genus respectively. There are great difference among the fungi compositions of different area,year and sampling season,while there was no obvious variation rule. Ilyonectria sp.,Pythium sp.,Phoma sp,Trichoderma sp.are dominant genus,while Pythium sp.,Ilyonectria sp.,Phoma sp.,Fusarium sp. may contain root rot pathogen. Antagonistic bacteria may be screened from the strains of Trichoderma sp. isolated.
