Composition and antifungal activity of essential oil of Artemisia sieberi Bess. on soil-borne phytopathogens

Abstract

Aerial parts of Artemisia sieberi Bess. were collected at flowering stage. The essential oil obtained by means of hydro-distillation and their chemical components were identified by GC-MS. The major components of the oil of A. sieberi found to be β-thujone (19.79%), α-thujone (19.55%), camphor (19.55%), verbenol (9.69%), p-mentha-1,5-dien-8-ol (6.39) and davanone (5.79%). The antifungal activity of the essential oil was evaluated in vitro against four soilborn phytopathogenic fungi. The oil was slightly effective against Tiarosporella phaseolina, Fusarium moniliforme and Fusarium solani whereas against Rhizoctonia solani exhibited high antifungal activity. © 2006 Asian Network for Scientific Information.
