Weeds present a significant hazard to crop production, necessitating the development of effective and sustainable strategies for weed management. Although synthetic herbicides are effective, concerns about their environmental and health impact have been raised. This study investigates the allelopathic potential, antimicrobial activity, and phytochemical profile of . Extracts from . proficiently impede the growth of and , while exhibiting varying effects on crops and . Leaf and seed extracts demonstrate the most significant inhibition of weed growth. Interestingly, the leaf extract at a concentration of 50% inhibited weed growth in pot experiments without affecting crop growth. Moreover, extracts from . exhibit noteworthy antifungal and antibacterial activity, with the root extract demonstrating the strongest inhibition. The root extract inhibited the mycelial growth of by 63% as compared to control. The leaf extract exhibited the highest levels of phenolic acids, in particular gallic acid, amounting to 116.30 ppm. This study emphasizes the multifaceted potential of . as a sustainable solution for weed management and proposes its use in crop protection. Further investigation of its practical applications and optimization of extraction methods can aid in its integration into contemporary agricultural systems, promoting both crop yield and environmental sustainability.
杂草对作物生产构成重大危害，因此需要制定有效且可持续的杂草管理策略。尽管合成除草剂有效，但人们对其环境和健康影响表示担忧。本研究调查了[植物名称]的化感潜力、抗菌活性和植物化学特征。[植物名称]的提取物能有效抑制[杂草名称1]和[杂草名称2]的生长，对作物[作物名称1]和[作物名称2]则表现出不同影响。叶和种子提取物对杂草生长的抑制作用最为显著。有趣的是，在盆栽试验中，浓度为50%的叶提取物在不影响作物生长的情况下抑制了杂草生长。此外，[植物名称]的提取物具有显著的抗真菌和抗菌活性，根提取物的抑制作用最强。与对照相比，根提取物对[真菌名称]菌丝体生长的抑制率达63%。叶提取物中酚酸含量最高，尤其是没食子酸，达116.30 ppm。本研究强调了[植物名称]作为杂草管理可持续解决方案的多方面潜力，并建议将其用于作物保护。对其实际应用的进一步研究和提取方法的优化有助于将其融入现代农业系统，提高作物产量并促进环境可持续性。
