| Zusammenfassuung: In diesem Bericht werden die wissenschaftlichen Ergebnisse nationaler und internationaler Studien zu den gesellschaftlichen Leistungen des Biolandbaus zusammengefasst. Als Referenzen werden dabei sowohl die konventionelle wie auch die integrierte Landwirtschaft herangezogen. Es ist den Autoren bewusst, dass alle Landwirtschaftsmethoden in der Schweiz und im Ausland eine grosse Streubreite aufweisen, da der Einfluss der regionalen sozioökonomischen Rahmenbedingungen, der Standortfaktoren, der Betriebsleiter und der unterschiedlichen staatlichen und privaten Regulierungen gross ist. Trotzdem ergeben sich für die verschiedenen Landwirtschaftsmethoden klare Unterschiede, die bei den agrarpolitischen Massnahmen berücksichtigt werden... |

| Different research groups have already proven that flowering plants in orchards can enhance beneficial arthropods. Even within the tree rows different beneficial can be supported by selected plant species. In most experimental work done to stabilize the apple production system only single interaction effects were tested. However until now, no research group has quantified the additive effects of multiple measures on systembiodiversity and on the production economy. Our experiment combines all known measures of indirect pest and disease control measures in a near-to practical production model orchard without the use of any pesticide (not even organic ones). The orchard is split in 4 blocks: in two of them bio-control measures e.g. application of Granulosis... |

| Seeds form the basis for agricultural production, but most organic growers know little about how their seedstocks have been produced. Within the organic movement the discussion on the compatibility of plant breeding techniques has been accelerated by the public discussion on genetic engineering. This decision-making is important to develop a framework for organic plant breeding and facilitate investment by breeding companies. This dossier explains all standard techniques used in modern plant breeding and why they have been developed. The consequences of not allowing certain techniques for organic plant breeding are outlined, along with suggestions for alternative techniques that could be adopted. |

| Two myco-insecticides, Naturalis-L (Beauveria bassiana) and PreFeRal®WG (Paecilomyces fumosoroseus), were applied against adult R. cerasi (Diptera: Tephritidae) in two orchards in north-western Switzerland in summer 2006. Both products were applied at a concentration of 5.75x104 CFU / ml. With four applications at seven day intervals the whole flight period of R. cerasi was fully covered. During this period (5th June – 6th July) the temperature averaged 19.2°C, total precipitation was 60 mm. Under these conditions Naturalis-L significantly reduced the number of damaged fruit (efficacy: 69-74%), whereas damage was not significantly reduced with PreFeRal®WG (efficacy: 27%). Fungus infested flies were found on the yellow sticky traps proving that the... |

| The organic market has grown exponentially in Europe during the last ten years. However, the organic fruit industry in European states still has a relatively low market share of less than 1-5% compared with organic vegetables, milk and eggs that have achieved market shares of close to 10% of the total market. As well, conventional fruit growers still hesitate to respond to the generally good organic market demand. A major reason for this behaviour is the continuing high production risk due to less availability of effective management tools for the control of pests, diseases, weed and biennial bearing. The key pests and diseases in apple and pear include scab, sooty blotch, and fire blight as well as rosy apple aphid, pear sucker and codling moth, as well... |

| 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... |
