Abstract
The surface properties of three types essential oils (Pinus sylvestris, Juniperus communis and Oreganum herachoticum) were investigated as application of adjuvants. The surface tension was measured in both pure oils and solutions with concentrations: 0.001, 0.01 and 0.1 % v/v at different temperatures: 10, 25, 30, 35 and 400C. After comparison of surface tension between three oil some low values exhibit Pinus sylvestris (33.61±0.21 to 16.13±0.11 mN.m-1) following of Juniperus communis (38.25±0.17 to 20.91±0.07 mN.m-1) and Oreganum herachoticum (41.93±0.15 to 25.75±0.12 mN.m-1). This results confirm that these essential oils can be used as adjuvants in agriculture.
