Ever-increasing demand for water to irrigate crops, support aquaculture, provide domestic water needs and to protect natural aquatic and riparian habitats has necessitated research to reduce impacts from a parallel increase in invasive aquatic weeds. This paper reviews the past 4-5 years of research by USDA-ARS covering such areas as weed biology, ecology, physiology and management strategies, including herbicides, biological control and potential for use of natural products. Research approaches range from field-level studies to highly specific molecular and biochemical work, spanning several disciplines and encompassing the most problematic weeds in these systems. This research has led to new insights into plant competition, host-specificity, and the fate of aquatic herbicides, their modes of action and effects on the environment. Another hallmark of USDA-ARS research has been its many collaborations with other federal, state action and regulatory agencies and private industry to develop new solutions to aquatic weed problems that affect our public natural resources and commercial enterprises.
对水的需求不断增加，用于灌溉作物、支持水产养殖、满足家庭用水需求以及保护天然水生和河岸栖息地，这使得开展研究以减少入侵水生杂草数量增加带来的影响成为必要。本文回顾了美国农业部农业研究局（USDA-ARS）过去4至5年的研究，涵盖杂草生物学、生态学、生理学以及管理策略等领域，包括除草剂、生物防治和天然产物的使用潜力。研究方法从田间水平研究到高度特定的分子和生化工作，跨越多个学科，涵盖这些系统中最具问题的杂草。这项研究为植物竞争、宿主特异性以及水生除草剂的归宿、作用方式和对环境的影响带来了新的见解。美国农业部农业研究局研究的另一个特点是与其他联邦、州行动和监管机构以及私营企业开展了许多合作，以开发解决影响我们公共自然资源和商业企业的水生杂草问题的新方案。
