| A novel formulation of potassium bicarbonate (Armicarb) was evaluated in 2004 and 2005 as agent against apple scab (3 field trials) and sooty blotch (2 field trials). Armicarb controlled scab equally well as the reference treatments sulphur and copper. Armicarb showed also excellent activity against sooty blotch. However, potential side-effects such as lenticell spot development need further investigation. At present, potassium bicarbonate is considered by the Swiss registration authorities as non-toxic to humans and in consequence, no residue levels have been specified. Armicarb has very interesting properties as a plant protection agent and its composition and risk profile are expected to fulfil the IFOAM standards for acceptance of novel plant... |

| We have examined the effect of Pen, an aqueous extract of the dry mycelium of Penicillium chrysogenum, on plant–pathogen interactions. Pen controlled a broad range of pathogens on several crop plants under greenhouse and field conditions. Pen protected grapevine from downy and powdery mildew (caused by Plasmopara viticola and Uncinula necator), tomato from early blight (caused by Phytophthora infestans), onion from downy mildew (Peronospora destructor) and apple trees from apple scab (caused by Venturia inaequalis) to a similar extent as fungicides such as copper and sulphur or well-known inducers such as benzothiadiazole or b-aminobutyric acid. Pen had no major direct fungicidal effect and is thus supposed to protect plants by activating their defense... |

| Downy mildew caused by the obligate biotrophic oomycete Plasmopara viticola is one of the most important and devastating diseases of grapevine. Copper-based fungicides are used to control the disease in organic vineyards. However, since 2006, copper use has been limited by an European Commission regulation. In this study conducted from 2004 to 2007, we tested materials that might replace copper in organic viticulture, under controlled greenhouse and field conditions at two locations in Europe (northern Italy and Switzerland). We tested 112 different treatments, including biocontrol agents, materials of animal origin, homeopathic preparations, inorganic materials, microbial extracts, natural derivatives, plant extracts, physical methods and synthetic... |

| 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... |

| 2003 wurden die Sorten Alowa, Corolle, Derby, Eden, Lady Jo, Maestro, Marlen, Melody, Naturella, Terra Gold und Trabant untersucht. Die Prüfung umfasste agronomische Aspekte (Eignung für biologischen Anbau, Ertrag) und Qualitätsaspekte (im Hinblick auf die Vermarktung als Speisekartoffeln, resp. für die industrielle Verarbeitung). Die Untersuchungen fanden schwergewichtig auf Biobetrieben statt. Die folgende Sortenbeschreibung fasst die wichtigsten Resultate und Entscheide zusammen: Alowa: Frühe Speisekartoffel. Durchschnittlicher Ertrag; Knollen oval, gelbschalig; Kochtyp B; schlecht lagerbar. Die Versuche werden 2004 fortgesetzt. Corolle: Frühe Speisekartoffel. Guter Ertrag; Knollen lang-oval; Schale gelb, glatt; Kochtyp B; mässig lagerbar. Da Corolle... |

| In organic agriculture, the control of several diseases is largely depending on copper fungicides. Yet, copper can accumulate in the soil if the annual input exceeds annual uptake by plants, which can have a negative impact on soil fertility. Its use should thus be avoided or reduced. The aim of the present study was to evaluate the efficacy of a bark extract of Magnolia officinalis Rehder and Wilson to control three pathogens including Plasmopara viticola (Berk. & M.A. Curtis) Berl. & De Toni (causing grapevine downy mildew), Venturia inaequalis (Cooke) G. Winter (causing apple scab), and Phytophthora infestans (Mont.) De Bary (causing potato and tomato late blight) under controlled and field conditions, and to identify compounds responsible for... |

| The plant and animal health care strategy in organic farming strengthensagro-biodiversity, protects the environment as well as animal and human health. In addition to fully exploiting preventive options, the use of external inputs such as plant protection products, fertilisers or veterinarymedicinal productsis allowed to prevent inacceptable losses in productivity or animal suffering. However, external inputs need to comply with organic standardsas well as European legislationand aretherefore carefully evaluated before any decision on acceptance is taken.Organic farming systems should aim at reducing dependency on off-farm fertilisers to the lowest feasable level to ensure closed nutrient cycles and avoid nutrient leakage and contamination. This policy... |

| We evaluated the effect of using farmyard manure (FYM) in combination with four weed control techniques on the hygienic quality of lettuce. Treatments with six replications included the application of fresh FYM on the soil combined with hand-hoeing (assumed high-risk) and fresh FYM incorporation combined with plastic mulch (assumed low risk). The experiment was repeated twice per season over two years at Bonn University, Germany. The amounts of enteric bacteria in all treatments were within the acceptable limits. Enterococcus was detected in the majority of the samples in concentrations up to 3.7 log10 CFU/g. The Escherichia coli contents of lettuce ranged between n.d. and 103 CFU/g. There was no consistent effect suggesting a specific risk linked to one... |

| Fertile soils are highly important for arable farming. To maintain soil fertility, crop rotation including legumes is applied, particularly in stockless farms. Yet, many commercial farms report yield reductions for legumes. The aim of the present study was to evaluate whether the causes for the observed soil fatigue can be narrowed down by a bioassay (modified differential diagnosis according to Bouhot) and whether this bioassay could be a useful tool to predict the suitability of a field to grow legumes. |
