The essential oil of Cotinus coggyria Scop.%26apos; leaves was found to be rich in alpha-pinene (43.1%), limonene (21.3%) and b-myrcene (8.5%). In the antimicrobial screening, essential oil was notably active on Staphylococcus aureus ATCC 29213, S. aureus ATCC BAA-977, Candida albicans ATCC 14053 and C. parapsilosis ATCC 22019 using the disc diffusion and volatilisation assays. The fumigant assay of the essential oil caused 70% and 100% mortality on the two pest adults of Acanthoscelides obtectus and Tribolium castaneum at 80 mu L L-1 air concentration at 96 h, respectively. In the toxicity assay on weeds, a dose-dependent decrease was observed in the germination and seedling growth of Silybum marianum and Portulaca oleracea. The present results indicated that oil could be suggested as an effective biocontrol agent in various fields.
