Control of Portulaca oleracea by boldo and lemon essential oils in different soils

2015

Soil characteristics influence plant growth and can affect the phytotoxicity of the essential oils. In this study chemical composition and herbicidal activity of Peumus boldus Mol. and lemon essential oils in different growing medium against Portulaca oleracea L. was investigated. Ninety-four compounds accounting between 95.5 and 99.8% of the total essential oil were identified by gas chromatography-mass spectrometry in boldo and lemon essential oils. Ascaridole (31.56. ±. 0.15%), p-cymene (21.58. ±. 0.09%) and 1,8-cineole (12.57. ±. 0.13%) were the main compounds in P. boldus whereas large amount of limonene (59.28%) followed of β-pinene (12.96%) and γ-terpinene (10.92%) were found in lemo…
