在过去的几年里，特定地点的杂草控制技术在精准农业社区中引起了兴趣。在田间管理杂草需要测量田间杂草的不同密度。决策模型有助于选择和调整的治疗，这取决于杂草侵扰。杂草控制可以用除草剂或机械进行。除草剂定点施用技术可以节省大量的除草剂。机械除草技术适应于田间杂草状况，适用于广泛的农作物。介绍了田间杂草的检测和管理技术。介绍了一种从图像中识别不同杂草种类和作物的系统，该系统自动生成杂草图。杂草的产量效应模型的开发和应用在农场研究实验设置。经济杂草阈值的推导和用于除草剂的应用与补丁喷雾器。
Site-specific weed control techniques have gained interest in the precision farming community over the last years. Managing weeds on a subfield level requires measuring the varying density of weeds within a field. Decision models aid in the selection and adjustment of the treatments, depending on the weed infestation. The weed control can be done either with herbicides or mechanically. A site-specific herbicide application technology can save large amounts of herbicides. Mechanical weed control techniques adapting to the weed situation in the field are applicable to a wide spectrum of crops.Site-specific techniques for the detection and management of weeds are presented. A system for the discrimination of different weed species and crops from images is described, which generates weed maps automatically. Models for the yield effect of weeds are developed and applied in on-farm-research experimental setups. Economic weed thresholds are derived and used for a herbicide application with a patch sprayer.
