Abstract: There are a lot of various types of pesticides, which are applied to plants, weeds and soils. Due to good selection effect, phenoxy acetic herbicide is often used for broad-leaved plants to protect grass and grain. Representatives of this group, that are met most often, are 2-methyl-4-chlorophenoxyacetic acid (MCPA). The aim of this study was to examine negative effect of MCPA to lichen Ramalina fraxinea physiological and biochemical parameters. Lichen has been exposed by different MCPA concentrations (0, 20, 50, 100 mg/l). Toxic effects were found after 48 hours when lichen change color. Our results showed that different concentrations of MCPA caused decrease in chlorophyll content, induced membrane lipid peroxidation and cell membrane damage in Ramalina fraxinea. It is concluded that MCPA had negatively affected physiological and biochemical parameters and caused oxidative stress
