The volatile constituents of Artemisia princeps var. orientalis (wormwood) were investigated for phytotoxic and antimicrobial activities. The germination and radicle elongation of receptor plants were inhibited by volatile substances emitted from wormwood leaf and effects were concentration-dependent. Essential oil of the plant extracted by Karlsruker's apparatus suppressed seed germination and seedling elongation of the receptor plants at a threshold concentration of 4.8 microliter/100 ml. Escherichia coli was not susceptible to the wormwood essential oil, but the growth of Bacillus subtilis, Aspergillus nidulans, Fusarium solani, and Pleurotus ostreatus was inhibited severely
