Growth inhibition of phytopathogens by the application of plant extracts.

摘要

The efficacy of the aqueous extracts of Terminalia chebula dry fruit and Piper betle fresh leaf was investigated against two phytopathogens (Sclerotium rolfsii [Corticium rolfsii] and Alternaria brassicicola) in laboratory conditions. Slants were prepared by incorporating the extracts into a PDA medium at 2, 5 and 10% concentrations with proper sterilization. T. chebula exhibited fungicidal property at 5 and 2% concentrations against S. rolfsii and A. brassicicola, respectively. P. betle documented minimum inhibitory concentration at 5% against A. brassicicola but established no effect against S. rolfsii even at 10% concentration.
