Abstract：
Aquatic weeds, including invasive species, are a worldwide problem. The presence of aquatic weeds poses several critical issues, such as hindering the continuous flow of water in irrigation channels and preventing the proper distribution of adequate water quantities. Therefore, effective control measures are vital for agriculture and numerous downstream industries. Numerous methods for controlling aquatic weeds have emerged over time, with herbicide application being a widely used established method of weed management, although it imposes significant environmental risks. Therefore, it is important to explore nonchemical alternative methods to control existing and emerging aquatic weeds, potentially posing fewer environmental hazards compared with conventional chemical methods. In this review, we focus on nonchemical methods, encompassing mechanical, physical, biological, and other alternative approaches. We primarily evaluated the different nonchemical control methods discussed in this review based on two main criteria: (1) efficiency in alleviating aquatic weed problems in location-specified scenarios and (2) impacts on the environment, as well as potential health and safety risks. We compared the nonchemical treatments with the UV-C-radiation-mediated aquatic weed control method, which is considered a potential novel technique. Since there is limited published literature available on the application of UV-C radiation used exclusively for aquatic weed control, our review is based on previous reports of UV-C radiation used to successfully control terrestrial weeds and algal populations. In order to compare the mechanisms involved with nonchemical weed control methods, we reviewed respective pathways leading to plant cell death, plant growth inhibition, and diminishing reemergence to justify the potential use of UV-C treatment in aquatic habitats as a viable novel source for aquatic weed control.
摘要：
水生杂草,包括入侵物种,是一个世界性的问题。水生杂草的存在带来了几个关键问题，例如阻碍灌溉渠道中的水的连续流动，并阻止适当分配足够的水量。因此,有效的控制措施对农业和众多下游行业至关重要。随着时间的推移，已经出现了许多控制水生杂草的方法，除草剂的使用是一种广泛使用的杂草管理方法，尽管它带来了重大的环境风险。因此,重要的是探索非化学替代方法来控制现有和新兴的水生杂草，与传统化学方法相比，潜在的环境危害更少。在这次审查中,我们专注于非化学方法，包括机械，物理，生物，和其他替代方法。我们主要根据两个主要标准评估了本综述中讨论的不同非化学控制方法：（1）在特定地点的情况下减轻水生杂草问题的效率和（2）对环境的影响，以及潜在的健康和安全风险。我们比较了非化学处理与UV-C辐射介导的水生杂草控制方法，这被认为是一种潜在的新技术。由于关于专门用于水生杂草控制的UV-C辐射的应用的公开文献有限，我们的审查是基于以前关于成功控制陆地杂草和藻类种群的UV-C辐射的报道。为了比较非化学杂草控制方法所涉及的机制，我们回顾了导致植物细胞死亡的各自途径，植物生长抑制，和减少的重新出现，以证明在水生生境中潜在使用UV-C处理作为水生杂草控制的可行新来源。
