| Weeds remain to be the main challenge within this agricultural system, especially perennials in the north European realm. Because of increased interest in agrobiodiversity functioning, weeds should be kept within manageable limits, while on the other side encourage a specie rich weed flora. One of the PRODIVA project objectives is to investigate to which extent these two aspects can be addressed through the use of diversified crop management. In order to research this objective, weed and management data were obtained from organic farms in the baltic region over the course of two years (2015-2016) in spring sown cereal crops. The impact of the local environment and management factors on the occurring weed communities was studied in multivariate analysis... |

| 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... |

| 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... |

| 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... |

| The main reason for controlling weed abundance in agricultural crops is the risk for qualitative and quantitative reductions in crop yields. Although there are no simple standard solutions available for weed control in organic agriculture, however, some cultural practices—in particular, undersow in spring cereals—can be critical components of weed management. To study this thesis, specific research has been carried out in the CORE Organic Plus PRODIVA project in six northern European countries—Denmark, Finland, Germany, Latvia, Poland & Sweden. Density of weed species were assessed in 109 organic fields situated in different agro–ecological conditions of region. The highest number of weed species fixed in surveyed fields was 93 (in Denmark). The most... |

| The research-network PRODIVA focuses on a better utilization of crop diversification for weed management in North European arable cropping systems. The goal is to maintain diverse arable weed vegetation that is manageable in the long-term and could fulfil other necessary system-functions including support of beneficial organisms. The partners in PRODIVA will synthesize knowledge from terminated and running research projects and set-up selected new experiments on cover crops and variety resp. crop mixtures. Moreover, we will interact with partners from farming practice and extension services in organic agriculture. Regional fields will be surveyed for weeds to safeguard the relevance of the experimental research. Current cropping practices and their... |

| PRODIVA-hankkeen (”Crop diversification and weeds”, 2015-2018,Core Organic Plus –ohjelma) tutkimusryhmät ovat keränneet yhdessä viljelijöiden kanssa tietoa, miten eri maissa noudatettavat luonnonmukaisen tuotannon viljelykäytännöt vaikuttavat rikkakasvilajistoon ja rikkakasveista aiheutuviin haittoihin. Posterissa kuvataan maatiloilta saatavan tiedon merkitystä kasvinsuojelututkimukselle. |
