abstract = "Allelopathic effects of the essential oils of two Nepeta species, Nepeta rtanjensis Diklié & Milojević and Nepeta cataría L., on selected weeds was examined. A GC-MS analysis showed that the essential oil of N. rtanjensis, an endemic species in Serbia, has the highest percentage of tran,cis-nepetalactone, while cis,trans-nepetalactone makes the highest percentage of essential oil in N. cataría. The effects of different concentrations of essential oils (O, 0.13%, 0.26%, 0.53%, 1.07%, 2.15% and 4.3%) on seed germination of the following weeds: Stellaria media, Arabidopsis thaliana and Rumex crispus, were compared. Both essential oils had a dramatic effect on germination of S. media seeds. Only the lowest concentration (0.13%) of both oils allowed germination, and it was mínimal (5%) in the presence of N. rtanjensis essential oil, while germination in the presence of N. cataría essential oil reached over 30% after five days. In the early stage, germination of A thaliana seeds was inhibited to different degrees by all concentrations of both essential oils. At the end of the germinating period, however, germination was lower only under the two highest concentrations (2.15% and 4.30%) of both essential oils, compared to control. The essential oil of N. rtanjensis had an extended effect of inhibition of A thaliana seed germination at lower concentrations, e.g. 1.07% concentration allowed seeds to germinate at the control level three days after those treated with the essential oil of N. cataría. R. crispus seeds were found unaffected by N. rtanjensis essential oil, while N. cataría essential oil even had a stimulating effect on germination on the first day of germination (third day of experiment). Data in the present study show that the essential oils of N. rtanjensis and N. cataría could be utilized as novel bioherbicides in future weed management programmes.",
