| Aus Gründen einer genügenden Wasser- und Nährstoffversorgung bedarf der Baumstreifen in Niederstammanlagen einer Beikrautregulierung. Erfolgt diese ohne Herbizide wird der Baumstreifen entweder mit organischen Materialien (Baumrinde, Holzhäcksel, Stroh) oder wasserdurchlässigem Kunststoffgewebe abgedeckt oder durch Hacken mit Spezialgeräten offen gehalten. Beide Methoden bergen jedoch gewichtige Nachteile in sich. Bei der Abdeckung sind dies die hohen Materialkosten, der z. T. hohe Kalieintrag (Erhöhung der Stippegefahr) und der erhöhte Mäusedruck. Das herkömmliche Hacken ist zeitintensiv, die Anschaffungs- und Wartungskosten geeigneter Hackgeräte sind hoch. Beim Sandwich-System bleibt ein schmales Band im Zentrum des Baumstreifens unbearbeitet. Links... |

| Organic fruit growers often suffer economic losses due to insect damages. The available natural pest control products are not always effective; and most important: many organic fruit growers would prefer not to use any pesticide at all. Growing flowers in order to gain more natural enemies, and hence less pests is a technique called Functional Agro-Biodiversity (FAB). Ongoing research in this CORE Organic Plus project aims to collect existing knowledge and generate new knowledge in order to use FAB successfully in orchards. |

| In Malaysia an intensively managed high input full sun cacao (Theobroma cacao L.) plantation can reach high yields of 1.5 to 2 t dry beans per ha. Following a high production period of 10 years the yields often decrease markedly. Focusing on leading depleted cacao plantations sustainably back to full production a research project was initiated in June 2011 using a diversification approach with agroforestry systems. The experimental site is located on a large commercial farm in the humid tropical lowlands of peninsular Malaysia, in the region of Kuala Lipis. In a field trial with a strip-split-plot design, three different production systems are compared under two tree age conditions: newly planted and old rehabilitated cacao trees, after the removal of the... |

| Due to higher prices in the organic compared to the certified integrated apple production, fruit growers are more and more interested in the conversion from integrated to organic production. With the return-risk profile based on Mouron (2001a) it is possible to identify the return and risks with economic indicators from the full cost account and the cash flow statement. Therefore, the return-risk profile serves as a basis for decision- making for producers concerning an evaluation to convert to organic. The return of the organic apple production is about 7% better than the certified integrated production. The risk of the organic production is higher because of the difficulty of braeking the alternanz and loss due to insect pests and diseases. The... |

| Orchards are perennial cultures, and, especially in organic fruit production it is essential to design and manage orchards in a way which favours beneficials such as insect predators and parasitoids over pests and diseases. As landscape-dominating crops their management affects overall biodiversity in the agricultural landscape. Increasing plant biodiversity and habitats in such a way that beneficials are favoured is called Functional Agro-Biodiversity (FAB). The value of FAB for reducing pesticide use in fruit production is generally acknowledged, and many growers try to increase it. However, they lack situation-specific information about how to drive and assess biodiversity to optimize FAB. ECOORCHARD is therefore combining several approaches: (i)... |

| The effects of organic and integrated production systems on the culturable fungal microflora of stored apple fruits from five matched pairs of certified organic and integrated ‘Golden Delicious’ farms were studied at five representative production sites in Switzerland. Isolated fungi were identified morphologically. Colonization frequency (percentage of apples colonized), abundance (colony numbers), and diversity (taxon richness) were assessed for each orchard. The standard quality of the stored fruits was comparable for both organic and integrated apples and complied with national food hygiene standards. Yeasts (six taxa) and the yeast-like fungus Aureobasidium pullulans were the dominant epiphytes, filamentous fungi (21 taxa) the dominant endophytes. The... |

| Die Landwirtschaft trägt weltweit mit 12–32 Prozent zum Klimawandel bei. Hauptquellen sind der Methanausstoss der Wiederkäuer, der CO2-Verbrauch für die Herstellung von Düngern und Pestiziden, die Abholzung von Wäldern für den Ackerbau und Weideflächen sowie die Bodenerosion. Auch der Einsatz des Pflugs verbraucht viel Energie, verstärkt den Abbau von Humus und belastet somit das Klima. Gemäss bisherigen Untersuchungen benötigt die biologische Landwirtschaft schon heute mit den gängigen Methoden weniger Energie als die konventionelle Bewirtschaftung. Im DOK-Versuch zum Beispiel verbrauchen die Bioverfahren 20 Prozent weniger Energie pro Ertragseinheit. Dies macht den Biolandbau zwar klimafreundlicher, aber noch nicht klimaneutral. Durch die Anwendung... |

| Damage of leaf spot, caused by Mycosphaerella fragariae and gray mold also called Botrytis fruit rot, caused by Botrytis cinerea, average fruit weight and yield were evaluated with regard to cultural methods over two years. Leaf spot damage decreased significantly by around 90 % due to leaf sanitation (removal of dead and leaf spot infected leaves in early spring) and by 50 % due to plantation in a one-row-system instead of a two-row-system. When all leaves including the healthy green ones were removed in early spring average fruit weight decreased significantly by 10 %. Fruit sanitation - the third treatment – did not influence any of the measured parameters. Neither leaf sanitation nor fruit sanitation (removal of damaged fruits during harvest) reduced... |

| A tool to ease the market introduction of scab resistant apple varieties in supermarkets, is the so-called «Flavour Group Concept (FGC; Weibel and Grab, 2000) that has been developed by FiBL and «Coop» (second biggest supermarket retailer of Switzerland) already in 1995. The FGC is providing to the buyers additional information on the specific flavour direction of that "unknown" apple cultivar in front of them (mild to sweet; spicy-tart; predominantly tart). In 2002 a consumer behaviour study was undertaken by «IHA/GfK-Switzerland» Institute to evaluate the consumer response to the FGC. The results reveal that 36 % of the persons interviewed at the point of sale considered additional information on the flavour direction of the apple cultivars as... |

| Conclusions and further studies The significant reduction of T. pyri and of larvae of predaceous gall midges, the complete loss of mite-diversity and the possible enhancement of P. ulmi and other harmful mites (i.e. C. vitis) are clear disadvantages of lime sulphur. Densities of T. pyri between 0.5 and 1 mite per leaf as mentioned to be necessary for controlling harmful mites (BOURQUIN 1989, FORTMANN 1993, HARZER 1993, KARG 1992, KOHLER ET AL. 1991), were never reached in lime sulphur treatment, while the untreated control always showed densities above this value. On the other hand low densities of predaceous mites are quite normal in intensively sulphur treated, biological orchards and are often replaced by other mite predators, like predatory... |

| Hauptziel des Sortenteams, das aus Vertretern von Coop, Abpackbetrieben, Produzenten und des FiBL besteht, ist die möglichst effiziente Optimierung des Sortenangebotes von biologischen Früchten nach sensorischen, agronomischen und ökologischen Kriterien. Das Sortenteam wählt aus bereits vorgeprüften Sorten solche aus, die bestehende Sortimentslücken schliessen oder bisherige Sorten verbessern könnten. Diese "Team-Sorte" wird auf 2-4 Bio-Betrieben im Vertragsanbau produziert. Die Gesamtfläche ist so gross, dass mit den Erträgen des dritten und vierten Standjahres Testverkäufe durchgeführt werden können. Für die Früchte der Testverkäufe erhalten die Produzenten eine vertraglich festgelegte «Pionierprämie». Aufgrund der agronomischen Erfahrungen der... |
