| L’agricoltura biologica, e in particolare la viticoltura biologica, sono cresciute considerevolmente nell’ultimo decennio ed hanno ancora ampi margini di miglioramento. Il progetto di ricerca VineMan.org (www.vineman-org.eu), finanziato nell’ambito del network europeo di cooperazione transnazionale CORE Organic II, ha l’obiettivo di migliorare il controllo delle malattie, uno dei principali e più difficili compiti del viticultore biologico, integrando la resistenza delle piante, pratiche agricole di gestione del vigneto, i sistemi di supporto alle decisioni e l’utilizzo di agenti di biocontrollo. |

| We developed a new protocol to study arbuscular mycorrhizal fungal (AMF) communities in Bordeaux vineyards in a standardized way, in order to compare results obtained over years and between locations. To this end, we first used grapevine root samples instead of soil samples to avoid AMF spores or hyphae interacting with cover plants. We next increased the number of grapevine samples to obtain more representative coverage of AMF communities while decreasing variability intra-vineyard, especially for the larger parcels. In addition, we adapted the DNA extraction protocol dedicated to soil samples to grapevine roots, as a way to increase the yield and the purity of samples. These features, coupled to the choice of the LSU-D2 region as the molecular marker for... |

| Based on a field trial, the impact of three different viticultural management strategies on vigour and grapevine physiology of Vitis vinifera cv. Riesling was compared. The vines were planted in 1991 at Geisenheim (Rheingau, Germany) and three different management strategies i.e. integrated (code of good practice), organic (European Union Regulation 834/07 and ECOVIN standard) and biodynamic (European Union Regulation 834/07 and DEMETER standard) were established in 2006. Even though all treatments received the same level of nutrients and water a decline in vigour, expressed as lateral growth, was observed for the organic and biodynamic treatment during three seasons (2010 to 2012). During dryer conditions (2011) a reduction of physiological activity... |

| The six products, Armicarb, Vitisan, lime sulphur, Caso, Calce Fiocco and Ulmasud were tested for their ability to control downy mildew (Plasmopara viticola) on grapevine (Vitis vinifera) in order to find effective alternatives to copper, a heavy metal that is commonly used as a fungicide in organic viticulture. Each product was applied to potted grapevines at i) 40°h (degree hours) and ii) 80°h after inoculation (ai) of the pathogen. These so-called stop-sprays were tested on plants that received two different P. viticola inoculum rates. The formulated potassium bicarbonate product Armicarb and lime sulphur reduced disease incidence and severity similar to or better than the copper hydroxide treatment. Armicarb and lime sulphur reduced disease incidence... |

| In der Schweiz stehen für die Bekämpfung von P. viticola Kupfer und Tonerdeprodukte wie Myco-San, Myco-Sin, und Ulmasud zur Verfügung. Die Praxis hat das Wirkungspotential gezeigt und es werden verschiedene Anwendungsstrategien angewandt. Der Einsatz von Tonerdeprodukten kann allerdings auch zu Phytotoxizität führen, die von der Anwendungsstrategie, Konzentration und Sorte abhängt. In dieser Studie (i) verglich das FiBL verschiedene Anwendungsstrategien mit und ohne Kupfer, (ii) untersuchte das aktive Prinzip und die Wirkungsweise der Tonerdeprodukte, und (iii) beschrieb den Einfluss von Umeltfaktoren wie Niederschlag auf die Wirkung. Die FiBL-Erfahrungen zeigen, dass Tonerdeprodukte wertvolle Kupferersatzprodukte sind in Situationen mit mittleren... |

| Organic farming is often considered to be the most environmentally-friendly crop management system, even if integrated production also aims at decreasing the impact of agriculture on the natural environment. In order to establish references for the agro-environmental evaluation of these two production systems in relation to grape growing, INRA carried out an initial study from 2001 to 2004 at the plot scale. This study focused on two grape varieties (Merlot N and Cabernet Sauvignon) in its Couhins vineyard (Graves cru classé), located on two organically-farmed plots and two plots using integrated production, a system based on the implementation of decision rules aimed at limiting the number of pest control treatments. Production means only differed in... |

| Die breite Wirkung des Schwefels (Stäubeschwefel, Netzschwefel) gegen unterschiedliche Schaderreger macht den weiteren Einsatz des Mittels sinnvoll und notendig. Beim Einsatz von Schwefel sind seine Nebenwirkungen (Raubmilbenbeeinflussung, Gär- und Geschmacksbeeinflussung) zu beachten. Schwefel stellt neben Kupfer eines der wichtigsten Pflanzenschutzmitteln im ökologischen Weinbau dar. Die möglichen Alternativen auf der Basis von Pflanzenstärkungsmitteln müssen auf ihre Wirkung (Abhärtung, Induzierte Resistenz, Nahrungskonkurrenz) wie auch Nebenwirkungen weiter untersucht und ihre Formulierungen verbessert werden. Der Einsatz von biologischen Präparaten z.B. AQ 10 oder Serenade gegen Oidium ist zu prüfen und gegebenenfalls zuzulassen. Inhalt:... |

| La drosophile du cerisier (Drosophila suzukii), qui est arrivée en Europe en 2008 depuis le sud-est de l’Asie, peut provoquer des dégâts considérables. Elle s’attaque à tous les fruits tendres comme les baies, les cerises, les prunes et le raisin. Et de nombreuses plantes sauvages comme le sureau et la viorne obier lui servent de plantes-hôtes. Les dégâts sont principalement causés par les larves qui mangent les fruits de l’intérieur. Vu que le cycle de reproduction est très court et que plusieurs générations apparaissent en parallèle, c’est en fin d’été et en automne que la pression d’attaque est la plus forte. Il faut s’attendre à une pression d’attaque particulièrement forte dans les vignes puisque le raisin est récolté plus tard que la plupart des... |

| The objective of the UE-funded program REPCO (FP6) was to identify new alternatives to copper fungicides in organic farming. Two pathogens have been considered: grapevine downy mildew (Plasmopara viticola) and apple scab (Venturia inaequalis). Research on grapevine was carried out by GRAB (Avignon, France) and FEM-IASMA (San Michele all’Adige, Italy). Trials were carried out under natural conditions in order to test reduced doses of copper and copper-free alternatives. Five-year trials proved that copper is the best fungicide. However, the use of new low copper rate formulations and the association of copper-free alternatives with reduced doses of copper or with reduced number of copper applications (limited to the most susceptible grapevine growth stages)... |

| In organic farming the copper compounds are the only substances that can be used against downy mildew. As the copper causes problems of environmental impact, the Regulation EC n. 473/2002 fixed a ceiling on its use. Two-years experimental trials (2007-2008) were carried out in organic vineyard in order to evaluate anti-downy mildew effectiveness of natural products. Homeopathic products, resistance promoters, plant extracts and potassium bicarbonate have been tested. In 2007, a year of limited infection pressure, these products were able to control the disease, whereas in 2008, a year of high risk of disease, the natural products were scarsely effective. In conclusion, the natural products can be used in alternative to copper in condition of low or... |

| Organic viticulture has grown considerably in the last decade; nonetheless, organic farming still has a huge potential for innovation and improved solutions specifically for the control of pests and pathogens. The research project VineMan.org (www.vineman-org.eu), funded by European Union within the CORE Organic II ERA-Net (project no. 249667), aims at improving disease control, one of the most difficult tasks in organic viticulture, through innovative cropping systems based on integration of: i) enhanced plant resistance, ii) vineyard management practices, iii) use of biological control agents, and iv) targeted applications based on disease models. During the first year, the above mentioned components of an integrated system have been developed and... |

| La flavescence dorée de la vigne et la lutte obligatoire contre son vecteur Scaphoideus titanus posent d’importants problèmes dans les vignobles conduits en culture biologique. Afin de développer une stratégie de lutte basée sur des insecticides compatibles avec la viticulture biologique, des essais en plein champ ont été conduits au Tessin en 2006-2007. Le Parexan N (pyréthrine + huile de sésame) s’est avéré le seul produit biologique efficace à plus de 90% contre les formes immatures de S. titanus, par contre il n’a eu aucun effet contre les adultes. L’application répétée de Parexan N s’est montrée toxique pour les typhlodromes de l’espèce Amblyseius andersoni. Malgré cette toxicité, la seule stratégie de lutte efficace et recommandée dans les vignobles... |

| Une lutte efficace contre les pathogènes fongiques de la vigne implique des connaissances de plus en plus fines sur l'organisme pathogène en question: ceci tant au niveau de sa physiologie, de sa génétique, de son mode de propagation et ses stratégies d'infection, que sur la modélisation de l'infection, le diagnostic, la détection précoce, de même que sur l'étude des mécanismes de résistance de la vigne contre ces différents pathogènes fongiques. L'étude des mécanismes de résistance de la vigne (induction d'enzymes particulières, par exemple stilbènes synthases, callose synthases contre Plasmopara viticola...) contre ces différents pathogènes au niveau moléculaire permet de mettre en évidence les gènes impliqués et d'étudier leur régulation, ce qui à long... |
