| Hanke-esittely ProAgrian viljelijöille, aluksi ppt-esityksenä sisätiloissa (liite) ja koekentillä Jokioisilla. Luonnonvarakeskuksen (Luke) luomupelloilla Jokioisilla aloitettiin keväällä 2015 kaksi kenttäkoetta, joissa tarkastellaan erilaisten aluskasvien ja niiden seosten soveltuvuutta rikkakasvien hallintaan viljavaltaisessa viljelykierrossa. Koealueiden esikasvina oli apila/heinä-nurmi, joka kylvettiin 2013 kaura-suojaviljaan. Vuonna 2015 aluskasvit kylvettiin joko heti Wolmari-ohran kylvön jälkeen tai ohrakasvustoon heinäkuussa. Aluskasveja oli yhteensä 16 kasvilajia ja 18 lajiketta. Niitä sekoittamalla saatiin 8 erilaista vaihtoehtoa, joiden tavoitteena on joko typen sidonta (palkokasvit) tai keruu (heinät). Seoksina kylvettiin sekä... |

| The weed flora in conventionally and organically grown spring cereals was investigated in southern and central Finland during 2007–2009. The survey was conducted in 16 regions, 283 farms and 595 fields (72 organically cropped and 523 conventionally cropped fields, of which 503 were treated with herbicides). The occurrence of weeds was assessed in late July–early August. Altogether 148 weed species were identified, of which 128 were broad-leaved and 20 grass species. In organically cropped fields, the average species number per field was 21 and the most frequent species were Chenopodium album 96%, Stellaria media 94%, Viola arvensis 94% and Elymus repens 89%. In conventionally cropped fields, the average species number was 12 and the most frequent weed... |

| Cover crops have gained popularity in cereal cropping now that they are one of the subsidized options in agri-environmental schemes of the EU. Several studies on cover/catch crops affecting nutrient leaching have been published but less information is available concerning their applicability for weed management. In our opinion, combinations of crop and cover crop types as well as crop sequencing conform IPM principles and optimize weed management. The PRODIVA project (ERA-Net Core Organic Plus Action, www.coreorganicplus.org) aims at identifying weed community associations with most common crop types in organic crop production systems. We will clarify the characteristics and relative competitiveness of cover crops providing strong weed suppression without... |

| 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... |

| In a joint experiment between Norway, Denmark, Finland and Sweden the dormancy of vegetative reproduction in Cirsium arvense, Sonchus arvensis and Elymus repens was studied during the latter part of the vegetation period.The aim of the study was to achieve a more efficient control of these weed species by knowing their reproduction behaviour in the autumn. |

| In order to study the biology and non-chemical control of perennial weeds, a three-year field experiment was established in 2001 at Vihti, southern Finland. The experiment was placed in a clay soil field under organic production, infested moderately with Cirsium arvense, Elymus repens and Stachys palustris, and heavily with Sonchus arvensis. |

| 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... |
