We aimed to evaluate the bioherbicide potential of Eucalyptus saligna leaf litter essential oil, its fractions and major compounds. Six essential oil fractions were obtained by preparative thin‐layer chromatography and analyzed by gas chromatography/mass spectrometry. Effects of the oil, its fractions and major compounds (1,8‐cineole and/or α‐pinene) diluted in aqueous solution were assessed on germination and seedling growth. Recipient species were Lactuca sativa (model), Amaranthus viridis (weed), Eragrostis plana (weed), and Paspalum notatum (forage). The essential oil was more phytotoxic on A. viridis and L. sativa, followed by E. plana, and caused no effects on P. notatum. Amaranthus viridis was inhibited by all treatments, mainly the essential oil, α‐pinene and fraction 6, whereas E. plana was more affected by the oil fractions. Results revealed the species‐specific phytotoxic effects of E. saligna essential oil, indicating its potential use for controlling A. viridis and E. plana. Phytotoxic effects of essential oils or their components should not be generalized, as effects may change according to recipient species.

桉树落叶精油的生物除草剂潜力
我们旨在评估 Eucalyptus saligna 树叶凋落物精油、其馏分和主要化合物的生物除草剂潜力。通过制备型薄层色谱法获得六种精油馏分，并通过气相色谱/质谱法进行分析。评估了在水溶液中稀释的油、其馏分和主要化合物（1,8-桉树脑和/或α-蒎烯）对发芽和幼苗生长的影响。受体物种是莴苣（模型）、绿色苋（Amaranthus viridis）（杂草）、画眉草（杂草）和雀稗（草料）。精油对 A. viridis 和 L. sativa 的植物毒性更强，其次是 E. plana，对 P. notatum 没有影响。Amaranthus viridis 受到所有处理的抑制，主要是精油、α-蒎烯和馏分 6，而 E. plana 受油馏分的影响更大。结果揭示了 E. saligna 精油的物种特异性植物毒性作用，表明其可能用于控制 A. viridis 和 E. plana。精油或其成分的植物毒性效应不应一概而论，因为效应可能会因受体物种而异。
