| The influence of site on resistance of grapevine (cv. Chasselas) to Plasmopara viticola was evaluated. Grapevine leaves from three vineyards in the region of Lake Neuchâtel (Switzerland) were tested for their susceptibility to P. viticola in the lab in five successive years (2004-2008), and the expression levels of four selected defense-related genes (Glucanase, Lipoxygenase 9, 9-cis epoxycarotenoid dioxygenase, Stilbene synthase) were studied in one year. In all five years of examination, differences between sites were substantial, with plants from site HAU being much less susceptible to P. viticola than plants from site AUV. Susceptibility of plants from a third site varied from year to year. Differences in susceptibility were mirrored in the... |

| The impact of soil type, long-term soil management, and short-term fertility input strategies on the suppressiveness of soils against soil-borne (Ocimum basilicum – Rhizoctonia solani, Lepidium sativum – Pythium ultimum) as well as air-borne (Lycopersicon esculentum – Phytophthora infestans, Arabidopsis thaliana – Hyaloperonospora parasitica) diseases was studied. Soils from field trials established in five European sites with contrasting pedo-climatic conditions were examined. Sites included (i) a long-term management field trial comparing organic and conventional farming systems (DOK-trial, Therwil, Switzerland) (ii) a short-term fertility input field trial comparing mineral and organic matter fertilisation regimes (Bonn (BON), Germany) (iii) two... |

| 1. Bekämpfung des Apfelschorfes Dank Optimierung der Bekämpfungsstrategie und der Anwendung von Alternativprodukten (u.a. Tonerdepräparate) sowie dem Anbau resistenter Apfelsorten wurden in den letzten Jahren klare Verbesserungen bei der Bekämpfung des Apfelschorfes in Bioanlagen erzielt. Bei grösserem Krankheitsdruck ist jedoch der Schutz bei den nicht resistenten Marktsorten immer noch unbefriedigend. Mit dieser Problematik befasst sich das FiBL weiterhin mit folgenden Forschungsrichtungen. 2. Regenfleckenkrankheit Die FiBL-Versuche der letzten Jahre haben gezeigt, dass mit Cocana RF ein guter Schutz der Äpfel gegen die Regenfleckenkrankheit möglich ist. Dabei spielt die Applikationstechnik eine entscheidende Rolle. Es ist offensichtlich, dass... |

| Die gezeigten Ergebnisse deuten darauf hin, dass einige interessante Alternativprodukte zu Kupfer in Entwicklung sind. Diese sind jedoch noch weit entfernt von der Marktreife. Mit den Tonerden stehen aber schon jetzt gute Alternativen zu Kupfer zur Verfügung, die uns erlauben, in normalen Jahren die Krankheitsentwicklung bei Reben zu kontrollieren. In der Schweiz sind vorerst die bekannten Alternativen mit Tonerde verfügbar. Seit 2004 ist Kaliumpermanganat neu in der Schweizer Bioverordnung aufgeführt. Kaliumpermanganat ist nicht in der FiBL-Hilfsstoffliste aufgeführt, da kein Handelsprodukt kommerzialisiert ist. Kaliumpermanganat kann aber im Handel bezogen werden. In Deutschland, Italien und Frankreich wird verschiedentlich Phosphit eingesetzt,... |

| The objective of REPCO is to contribute to the replacement of copper fungicides in organic agriculture by new measures for control of downy mildew (Plasmopara viticola) in grapevine and scab (Venturia inaequalis) in apple. Both major European organic crops strongly depend on copper fungicides. Permitted amounts will be reduced stepwise during the following years (Council Regulation (EEC) 2092/91, Annex II) to avoid environmental risks. In European countries where copper fungicides are already out of use, production of organic apples suffers severe economical problems because of insufficient scab control. Potentiators of resistance, organically based fungicides and biocontrol agents are screened and evaluated in apple. Effects of crop management practices... |

| The data requirements and the administrative procedure needed for the registration of biological plant protection products and their active ingredients (micro-organisms including viruses, plant extracts, and semiochemicals) are described for the European Union, the USA, Canada und Australia and compared between these systems. Experiences from registration procedures are compared. While data requirements and formalities are rather similar in all systems considered, the time span needed for evaluation and the possibility to predict this time span are quite different. Alternative regulatory measures existing in different regulatory systems are described and initiatives for the facilitation are presented. |

| 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... |

| BACKGROUNd There is growing demand to replace chemical pesticides with alternatives owing to concerns related to impacts on human health and the environment. Plant-derived plant protection products could provide sustainable and environmentally friendly alternatives to chemical products. The aim of this study was to identify plant and fungal extracts with so far unknown activity against important plant pathogens by in vitro screening of a library of more than 3000 extracts. RESULTS Several plant extracts with promising in vitro fungicidal activity (MIC100 ≤ 50 µg mL−1) towards one or several of the investigated pathogens (Venturia ineaqualis, Phytophthora infestans, Plasmopara viticola) were identified by the screening. One of the hits, an ethyl acetate... |

| This proceedings volume contains the papers presented at the CODIS 2008 congress held on 27 - 29 February 2008 in Solothurn (Switzerland).The composting and digestion of biogenic waste materials and the subsequent application of compost and digestate to soil contributes to nutrient recycling and renewable energy production. Moreover, compost and digestate can improve soil fertility and suppress plant diseases. On the other hand, compost and digestate may also contain a variety of pollutants hazardous to soil, such as heavy metals and organic contaminants.Compost and digestate have been thoroughly investigated in the framework of two associated projects entitled Organic Pollutants in Compost and Digestate in Switzerland and Effects of Composts and Digestate... |

| Quote from the article "Potassium phosphite, also called «phosphonate», is a salt of phosphonic acid with the formula K2HPO3. It should not be confounded with phosphates, nor with the organophosphorous insecticides which are also called «phosphonates». Potassium phosphite can be used as a fungicide against oomycetes in various crops. In the early 1990ies, it was extensively tested on organically grown grapevines in Switzerland. It was effective against downy mildew (Plasmopara viticola), and blocked the disease up to 3 days after infection. Phosphite was mobile and very persistent in plants and could be detected in grapes harvested one year after the last application. Analyses of 53 wine samples reveiled that the treatment inevitably leads to... |

| Potatoes are very suitable for direct marketing thanks to their diversity. Good yields are necessary to cover the high costs for cultivation and mechanisation. The very high-quality demands in every marketing sector require the most careful maintenance, which includes preparation of planting material, plant protection, nutrient and water supply as well as harvest and storage. This manual provides a good basis to achieve high-quality products. Experienced organic potato farmers can enhance their knowledge with specialist advice and additional literature. |

| 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... |
