Abstract
Laboratory and greenhouse experiments were conducted to evaluate the Allelopathic potential of essential oils isolated from Eucalyptus, Clove, and Lemongrass plants with different concentrations on seed germination and seedling growth of Silverleaf nightshade invasive weed Solanum elaeagnifolium 1,8. cineole was the dominant compound in eucalyptus oil, 61.70%±3.0. Eugenol accounted for 68.7%±3.05 of the total identified compounds in clove oil, while Neral 25.4%±1.07 and Geranial, 22.7%±0.96 were the highest compounds found in Lemongrass oil. The results show that essential oils extracted from Eucalyptus and clove, with a concentration of 10 µl ml -1, showed a high effectiveness (100%) in inhibiting seed germination completely. Also, the concentration showed high efficacy for reducing seedling development; a weed seedling was achieved at 10 µl ml-1 concentration, even for essential oils, which did not show a significant effect in suppressing seed germination. Based on the results above, Eucalyptus and Clove essential oils have interesting herbicidal activity against seed germination and seedling development of S. elaeagnifolium. These compounds are interesting as they can be used as effective and safe alternatives to conventional synthetic herbicides, effective and safer against seed germination and seedling development of weeds
