| Wühlmausschäden sind weit verbreitet und gehören zu den nur schwer lösbaren Pflanzenschutzproblemen im ökologischen Landbau. Nach einer Umfrage des Institutes für Nematologie und Wirbeltierkunde der Biologischen Bundesanstalt für Land- und Forstwirtschaft (BBA), im Jahre 2002 waren 90 % der befragten Obstbaubetriebe von Wühlmausschäden betroffen. Als Hauptschadensverursacher treten vor allem die Schermaus (Arvicola terrestris ), auch große Wühlmaus genannt, und die Feldmaus ( Microtus arvalis) auf. Mit den wenigen zur Verfügung stehenden Mitteln erreicht aber nur ein Bruchteil der ökologisch wirtschaftenden Betriebe einen akzeptablen Bekämpfungserfolg. Von Wissenschaft und Industrie werden viele Anstrengungen unternommen, um bekannte Abwehrmaßnahmen zu... |

| Wühlmausschäden gehören zu den am schwierigsten lösbaren Pflanzenschutzproblemen im ökologischen Obstbau. Nach einer Umfrage waren im Jahr 2002 79 % der deutschen Apfelanbaubetriebe von solchen Schäden betroffen. Auf 80 % der Flächen war die Schermaus (A. terrestris) der Hauptschadensverursacher. 61 % der Obstbauern sahen einen hohen Bedarf an der Entwicklung neuer Präventiv- und Bekämpfungsmaßnahmen. Um die Einwanderung von Wühlmäusen in Obstbauflächen zu verhindern, wurde ein mechanisches Barrieresystem entwickelt und an je einem Standort in Baden-Württemberg und Rheinland-Pfalz getestet. An jedem Standort wurden zwei ca. 0,7 ha große Parzellen mit Barrieren aus Drahtgitter (Maschenweite 10 mm) bzw. Polyolefin-Folie umgeben. Zwei ungeschützte... |

| Krähenschäden nehmen insbesondere auf Biomaisäckern zu. Durch die Beizung mit «Mesurol» sind konventionelle Maissaaten vor Krähenfrass geschützt. Das erhöht den Druck auf die Biosaaten. Für die Biobauern entstehen teilweise hohe Mehrkosten für Nachsaaten und verspätetes Ernten. Einzelne Landwirte haben sogar ganz mit dem Maisanbau aufhören müssen. Im Jahr 2012 wurde die Wirkung der Ballone und der Maiskörnerbeizung gegen Krähenfrass weiter erforscht. Das Ziel der über dem Feld schwebenden Ballone ist, die Krähen abzuschrecken, indem sie Raubvögel simulieren. Mit der Beizung will man eine Geruch oder Geschmack abschreckende Wirkung erreichen. Das soll das Auspicken der Körner verhindern. Die letztjährigen Versuche mit der Ballon Methode haben unter... |

| In this study several oil press cakes were investigated as exclusive substrates for different moulds and yeasts for the production of flavor-active decalactones via solidstate fermentation (SSF). Experiments are focused on pre-treatment methods for olive cake to remove antimicrobial phenolic substances contained in the oil cake disturbing or even inhibiting microbial growth. Choosing Ceratocystis moniliformis as the reference microorganism best results were obtained by a combination of hot water flushes and enzymatic treatment of the cake. Fermentation with sunflower, olive and linseed cake did not lead to lactone formation in detectable amounts although all of these substrates provided good microbial growth. On castor cake, however, five microorganisms... |

| Effekten av tre ulike konserveringsmetoder for bygg på fôropptak og melkekvalitet i økologisk landbruk ble testet i et fôringsforsøk med cross over design med tre perioder á en uke. Kyrne ble tildelt 6,0 kg TS (førstekalvskyr 5,0 kg TS) av enten tørket bygg (Arve), valset bygg ensilert med melasse, eller valset bygg ensilert med syrer. I tillegg til bygg ble kyrne tildelt grassurfôr ad libitum og en mineral/vitamin-blanding. Forsøket ble gjennomført i Bodø i mars 2004. Alle de tre metodene konserverte bygget godt. Konserveringsmetoden hadde ingen innvirkning på det totale fôropptaket. Kyrne var i sen laktasjon og melkeproduksjonen var lav, men det var ingen forskjell i ytelse mellom konserveringsmetodene for bygg. Innholdet av råprotein var lavt i... |

| To advance the generic science of advanced automation in agriculture with a view to providing the underlying science necessary for increasing productivity, lowering inputs and reducing environmental impact. To solve the generic scientific problems associated with precision vision guidance spanning multiple drill/planter bouts. To verify our hypothesis that the proposed sensing and tracking technologies will when developed and integrated form a robust basis for crop protection based on mechanical and chemical precision-banded treatments. It is our ambition to make vision guided banded treatment the preferred technique for most post emergence crop protection operations. Objective 1. To develop generic integrated image analysis and Kalman... |

| A wide range of quinoa pests are known throughout the world. The most serious of the Andean pests are Eurysacca melanocampta (Meyrick) and E. quinoae Povolny´ (Lepidoptera: Gelechiidae), found mainly in Peru and Bolivia, which cause considerable yield losses. Insects found elsewhere in the world are polyphagous pests constituting a wide range of potential pests if quinoa is implemented as a crop in those regions. Other major pests include a group of cutworms (Noctuidae). Apart from insects birds cause a major loss through foraging, damaging cotyledonous plants and inflorescences, with yield losses of up to 60%. Cultural practices and host plant resistances will be important components of integrated pest management (IPM). Biological control of the main... |

| This is the final report of Defra project OF0143. Choice of break crops to grow in addition to cereals and the fertility building phase is crucial to the agronomic and economic success of organic arable rotations. There are four specific functions that a break crop may perform, namely: addition, conservation and cycling of nutrients; pest and/or disease control; weed control and improvement in soil physical characteristics. Individual break crops may perform one or several of these functions. A good break crop must also produce satisfactory yields, be of marketable quality and produce an economic return for the farmer. This project analysed the overall suitability of new break crops by simultaneous assessment of key agronomic, economic and environmental... |

| Climate change scenarios exhibit a definite warming trend (Schröter et al. 2005), and it will have an impact on crop management strategies. Increase in winter precipitation and higher temperatures favour soil borne pathogens and can lead to an increase in survival rate and to more rapid population buildup (Chakraborty et al. 2000). In recent years, one of the main reasons for declining production of summer pea in organic farming in Germany are foot and root rot pathogens (Pflughöft 2008). On the other hand, predicted increase in winter temperatures is expected to favour winter pea over summer pea varieties. The hope is also, that winter peas are less susceptible to root rot as summer peas. However, few data are available. The present study was carried out... |

| Currently, the only effective treatment for cocoa (Theobroma cacao L.) infected with the cocoa swollen shoot virus disease (CSSVD) is to cut and replant infected trees. Hence, the development of preventive control measures and strategies to mitigate the severity of the disease are of utmost importance. While past research has mainly focused on resistance breeding, mild strain cross protection and vector control, diversification measures such as agroforestry have received relatively less attention, despite their potential to mitigate CSSVD severity. Therefore, we studied the effects of shade on CSSVD symptom severity, capsid damage and cocoa yield along a gradient of increasing shade tree abundance in smallholder cocoa farms in Ghana. Furthermore, we... |

| The general ecological mechanisms that determine the interactions between availability of re-sources (nutrients, water) and synthesis of defence related secondary metabolites in the plants will be presented. In short, under normal conditions in nature, where growth is limited by a relatively constant availability of nitrogen at a moderate level, plants strike a balance between defence and growth. They use a fraction of resources such as carbohydrate, N and S to reach a genetically determined normal level of defence mechanisms, which will prevent or quickly overcome most types of infections. If the local availability of nitrogen happens to increase (e.g. from decomposition of animal faeces), the growth rate increases, and the balance shifts. The... |

| The pilot system for forecasting insect migrations to next two days will be operated during May and June 2008. Forecasts are concentrating on two major pests; namely diamond-back moth and bird cherry aphid. Five to ten pilot users will get automatic SMS warning messages and are able to study the situation more thoroughly via specific web pages. The pilot users report to the study team about their findings and the usefulness of the service. The validity of the service will be tested using field traps. |

| Projektet bygger på upptäckten att allelobiotisk kommunikation mellan växter inducerar resistens mot skadedjur (bladlöss) och gynnar sökbeteendet hos deras naturliga fiender(nyckelpigor). Med särskild inriktning på förhållandena i ekologisk odling ska växtmaterial (sorter och arter) som kan användas för att utveckla odlingssystem som tillvaratar denna växtskyddsresurs identifieras. Särskild uppmärksamhet ska ägnas vårstråsäd (korn). För att kunna optimera funktionen av det allelobiotiska systemet ska undersökningar även göras av den inducerade resistensens mekanismer, t.ex. lokalisering av barriärer i cellvävnad och aktiva substanser. Likaså ska förhållandet mellan konstitutionellt försvar och inducerad (allelobiotiskt) resistens undersökas med avseende på... |
