Betel Vine Leaf Extract Inhibits Mildew Fungus of Nyctanthes arbor-tristis Growth under in vitro Conditions

K. Sumangala Bhat, Jose Thomas, Vivek Kempraj, A. Danesh and B.Y. Sridhara

Abstract:
Powdery mildews are a group of common pathogenic fungi infecting wide range of host plants, often causing serious damage and crop loss. Considering the indiscriminate application of synthetic fungicides and their hazardous environmental impact, development of safer alternatives became crucial. In an attempt to investigate the efficacy of betel vine leaf extract on powdery mildew of Nyctanthes arbor-tristis, in vitro culture method for the fungus has been developed and comparative efficacy of the extract on the pathogen has been evaluated with commercial fungicide, Bavistin. Biochemical profiling of the hexane extract of betel vine leaf by GC/MS has indicated the presence of 29 different compounds, with Safrole and eugenol as the major components. Successful propagation and confirmation of viability of the mildew under in vitro conditions have been established. Bioassay on mycostatic efficacy of the hexane extract of betel vine leaf on mildew has yielded MIC of 6%. The study has confirmed potential of betel vine leaf extract for development of safer alternative fungicide to regulate mildew disease of plants.
