Abstract: For utilization of the resources of Nepeta cataria, the bioassay of ethanol extract against 4 pathogenic fungi isolated from grapes were carried out by mycelial growth rate method. The results showed that when the concentration of extract was 5.0 mg/mL, the inhibition rate against Coniothyrium diplodiella, Glomerella cingulate, Botrytis cinerea and Aspergillus carbonarius was 94.57%, 70.23%, 71.15% and 26.06%, respectively. The inhibition rate against carbendazim high resistant strains FJND-9, FJND-40 and GZSD-89 of G. cingulate was 64.10%, 68.73% and 72.94%,and the inhibition rate against carbendazim high resistant strains HBLF-10, GXZY-4 and GXZY-7 of B. cinerea was 57.47%, 66.83% and 64.90%, respectively, when ethanol extract was at same concentration. This study provides a basis for the prevention and control of grape diseases using non chemical pesticides.
