摘要(Abstract):

Pectobacterium chrysanthemi is one of the main pathogens of soft rot disease of Amorphophallus konjac. The bacteriostatic effect of extracts from 10 kinds of traditional Chinese medicine and garlic on Pectobacterium chrysanthemi was studied in this experiment. The results showed that the extracts of Coptis chinensis, garlic, Scutellaria baicalensis, Mume Fructus and Bupleurum had significant bacteriostatic effect. Among them, Coptis chinensis and garlic had the best bacteriostatic effect on Pectobacterium chrysanthemi, and the diameter of inhibition zone was 2.27 and 2.19 cm, respectively, followed by Scutellaria baicalensis, with the diameter of inhibition zone of 1.68 cm. The extracts of Coptis chinensis, Scutellaria baicalensis and garlic with good bacteriostatic effect were diluted by double dilution method, and the bacteriostatic effect was determined. The results showed that 2-fold dilution of Coptis chinensis and 2-fold and 4-fold dilution of Scutellaria baicalensis had significant bacteriostatic effect, but the bacteriostatic effect of garlic extract was not obvious after dilution.
