| Diversification of crop sequences (WP 1): Perennial weed species can be managed when cover crops / green manure crops are included in the crop sequence but interventions must be species dependent, e.g. Elytrigia repens can be promoted by green manures because they prevent post-harvest cultivations. Cirsium arvense and Sonchus arvensis are two perennials that can be controlled by full-season grass-clover subjected to regular mowing for green manuring purposes and this measure has immediate application. Cover crops for diversification (WP 1): Fast growing cover crops producing copious biomasses are generally useful for the suppression of weeds but need to be abandoned when severe infestations of Elytrigia repens require post-harvest cultivations for... |

| Within the ERA-net CORE Organic Plus transnational programmes supported project PRODIVA producing of the information required for a better utilization of crop diversification for weed management in North European organic arable cropping systems was started. To fulfill the goal of this project- not to eradicate weed problems, which is unlikely to happen in any arable farming system, but to maintain a diversified and manageable weed flora that can support beneficial organisms- there were data from ongoing long-termed cropping system experiments from Latvia analyzed. It is hypothesised that: a) perennial weeds can be suppressed in the post-harvest period by improved cover crop establishment and pertinent selection of cover crop species; b) on-farm... |

| To organize and manage the dissemination process has become a general task within international projects. Within the project PRODIVA (Crop diversification and weed management) we organized these chains as returning cascades between practice (advisors and farmers) and scientists in the Baltic area. A network of farmers was created in each participating region. We collected and used practical knowledge about dominating weed species in Organic spring cereal production. This data can be compared with monitored weeds in the regions. Together with the monitored weeds management data was collected on-farm. Relating this data to the results of experimentally investigated crop diversification tools, being subsidiary crops in the rotation, crop mixtures and variety... |

| They create a great source of agro biodiversity, generating habitats and food sources for other organisms; yet weeds have always posed the greatest challenge in Organic Agriculture from the perspective of production. Because of the specific agricultural management of this farming system, several groups of weed species have naturally adjusted. These can be highly competitive to the crop, acquire high inputs to remove and/or spread rapidly. In this leaflet we will describe the most challenging weed species in organic spring sown cereals in the geographical area of the Baltic sea, based on existing literature and information provided by extension services. We will show and discuss their distribution from country to country and propose a classification... |

| Weeds are a perpetual challenge in Organic agriculture. However, they serve multiple ecosystem services and a low competitive weed cover can be tolerated. Adding to this, is the fact that only a few species prove problematic for both the crop and the farmer. The international PRODIVA project researches the effect of crop diversity strategies on the diversity of weed communities, hypothesizing that by increasing the weed diversity, the development of problematic weeds will mitigated. A preparatory study was conducted to list the most problematic weed species in spring sown cereals in the countries involved with PRODIVA. For this a literature review was conducted in all participating countries, collecting local sources including grey literature. This was... |

| Implications - Specific annual and perennial weeds are a perpetual challenge in the process of tuning up sustainable Organic production. To utilize the perspective of agro-biodiversity would both improve crop yields as well as conserve the ecosystem services of this agriculture system. The successful use of crop diversity strategies provides an additional tool in the toolbox of the farmers, giving them a) an overview of problematic weed species and b) the opportunity to plan their crop diversity based weed management over the course of years in the future. |
