The objective of AC/DC-weeds is to develop, examine and implement more and better agro-ecological management for creeping perennials in arable farming. Overall aim is to reduce plough-tillage in organic and conventional farming - in the latter also to replace glyphosate applications. Fields with less herbicide use to control perennial weeds would allow more biodiversity in the annual weed vegetation. Novel approaches for agro-ecological management of perennial weeds demand to exploit, combine and evaluate cultural, physical and bio-based chemical control. Creeping perennials are suppressed by disturbance or through competition hence, an agro-ecological management must activate these processes in a suitable and rational way. We propose to investigate new ways of agro-ecological management based on a better understanding of these processes. Seven partners from 5 European countries, representing a considerable area of Central and Northern European climatic and arable production conditions want to collaborate. AC/DC-weeds will be organized in 7 work packages. Each work package uses the most promising methodology regarding the state of knowledge, expected results and the envisaged outreach.New ways of applying disturbance subterranean without turning the soil will be examined in field experiments together with defoliation strategies with biocompatible herbicides. Results from joint field experiments will test efficacy and practicability of these new ways. The effects of enhanced competition are frequently investigated. Existing results on creeping perennials will be systematized in a meta-analysis. The extracted knowledge will feed a trait-based joint database. Three most important species in Central and Northern Europe differ in biology and ecology. Specific data for Elymus repens, Cirsium arvense and Sonchus arvense are pooled, knowledge gaps identified and close through specific small scaled experiments. We follow new approaches to spatially explicit monitor these perennials with available sensors installed in drones. Reliable algorithms will be developed to distinguish and monitor perennials. Qualitative models to analyse the impact of cropping practices, soil, weather and field environment on perennial infestations will be designed. With the help of a novel interactive graphical web tool spatial visualization for different scenarios of applying disturbance and competition will be developed. Coordination fundamentally ensures data flow, exchange and communication among partners. A data framework is provided to feed experimental results, descriptive and analytical trait and species based approaches into technological applications. Dissemination of the results is coordinated and supported. As outreaching results will aim on altering cropping technologies, evaluation of effects on the environment and on economic will be provided to accomplish dissemination. Results and products of all WPs and partners will be disseminated.

AC/DC-杂草的目标是开发，检查和实施更多和更好的农业生态管理的多年生匍匐植物在耕地。总体目标是减少有机耕作和传统耕作中的翻耕-后者也是为了取代草甘膦的应用。使用较少的除草剂来控制多年生杂草的田地将使一年生杂草植被具有更多的生物多样性。多年生杂草的农业生态管理的新方法需要开发，联合收割机和评估文化，物理和生物为基础的化学控制。多年生匍匐植物受到干扰或竞争的抑制，因此，农业生态管理必须以适当和合理的方式激活这些过程。我们建议在更好地理解这些过程的基础上，研究农业生态管理的新方法。来自5个欧洲国家的7个合作伙伴代表了中欧和北方相当大的气候和耕地生产条件，希望开展合作。AC/DC杂草将被组织在7个工作包。每个工作包都使用了最有前途的方法，包括知识水平、预期结果和设想的推广范围。将在实地实验中研究在地下施加扰动而不翻土的新方法，以及使用生物相容性除草剂的落叶策略。联合田间试验的结果将检验这些新方法的有效性和实用性。人们经常研究加强竞争的影响。现有的结果匍匐多年生植物将系统化的荟萃分析。提取的知识将提供给基于特征的联合数据库。中欧和北方欧洲最重要的三个物种在生物学和生态学上有所不同。具体的数据，欧洲蓟repens，小蓟和苦苣菜汇集，知识差距确定和关闭通过具体的小规模实验。我们遵循新的方法来空间明确监测这些多年生植物与安装在无人机上的传感器。将开发可靠的算法来区分和监测多年生植物。将设计定性模型，分析耕作方法、土壤、天气和田间环境对常年虫害的影响。借助一个新的交互式图形网络工具的空间可视化应用干扰和竞争的不同场景将开发。协调从根本上确保了合作伙伴之间的数据流动、交换和沟通。提供了一个数据框架，将实验结果、描述性和分析性性状以及基于物种的方法输入技术应用程序。对结果的传播进行了协调和支持。由于推广成果的目的是改变种植技术，因此将提供对环境和经济影响的评估，以完成传播。将传播所有妇女方案和伙伴的成果和产品。
