The essential oil of Cotinus coggyria Scop.' leaves was found to be rich in α-pinene (43.1%), limonene (21.3%) and β-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 μL 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.
