Natural products have been proven effective in controlling invasive plants in agricultural production areas. Among these, the essential oils stand out as being good allelopathic agents. The aim of this study was to evaluate the essential oil phytotoxicity of M. laevigata on the initial growth of the invasive plants Bidens pilosa and Digitaria insularis. The essential oil was extracted by the hydrodistillation method and its components were analyzed by GC-MS. The Inhibition of initial growth of the two invasive species used at this study was evaluated using two concentration of the essential oil (0.5 and 1%). The following parameters were analyzed: lengths of the roots and aerial parts of the seedlings. When the effects presents significants, the data were submitted to the analysis of the means, which were compared by the Tukey test, with 5% significance. Germacrene D (41.6%) was the main chemical constituent found in essential oil. For the two invasive species tested, the concentration of essential oil at 1% was the one that presented the best results for the parameters analyzed.
