Anfälligkeit einer Sommererbse gegenüber Isolaten von Pathogenarten, die von symptomfreien Kleearten und Wicken isoliert wurden Organic Eprints
Šišić, Adnan; Bacanovic, Jelena; Bruns, Christian; Finckh, Maria R..
Integration of additional leguminous living mulch and cover crop species holds a great potential for reducing external inputs and improving agricultural sustainability. However, changes towards legume rich crop rotations raises concerns as many of the species of interest share important soil-borne pathogens with some important main crops such as peas, beans and cereals. The pathogenicity towards the spring pea variety Santana was determined for 67 isolates of Fusarium oxysporum, F. solani, F. avenaceum, Didymella spp., Phoma medicaginis and Phoma spp. obtained from seemingly healhty roots of Trifolium subterraneum, T. repens, Vicia villosa and V. sativa. Only one isolate of F. solani and two isolates of Phoma spp. were nonpathogenic. F. avenaceum isolates...

Biofumigation - an alternative method to control late blight in organic potato production? Organic Eprints
Grabendorfer, Sebastian.
To control late blight in organic potato production currently copper fungicides are used. Due to problematic aspects of copper fungicides, it's necessary to develop alternative methods to control Phytophthora infestans. In this context also the use of cover crops and particularly the method biofumigation are discussed. Because there's barely literature about the effectiveness of biofumgiation in organic potato production, the method is evaluated with laboratory experiments and field trials. Brassicacea have the potential to inhibit in vitro the growth of P. infestans, but in an one year field experiment it wasn't possible to observe positive effects to late blight infestation and tuber yields.

Blattlaus- und Erbsenwicklerbefall in Wintererbsen-Reinsaaten: Ein Vergleich zu Sommererbsen-Reinsaaten und Wintererbsen-Mischsaaten Organic Eprints
Gronle, Annkathrin; Böhm, Herwart.
The infestation of peas by aphids and moths was assessed in winter pea sole crops and compared to spring pea sole and winter pea-triticale intercrops. The field experiments were conducted in Northern Germany in the growing seasons 2009-2011. The maximum number of pea aphids per plant and the percentage of attacked plants were lower in semi-leafless and normal-leafed winter pea sole crops than in semi-leafless spring peas. Pea moth larvae damaged 6-32 % of seeds in winter peas and 40-55 % of seeds in spring peas. Winter pea-triticale intercropping reduced the attack of pea aphids, whereas no beneficial effect of intercropping was observed concerning moth-damaged peas. Owing to the earlier maturity, winter peas were less susceptible to pea pest attacks than...

Crop rotation and its ability to suppress perennial weeds Organic Eprints
Askegaard, Margrethe.
The appropriate combination of crops and green manures prevents spread of perennial weeds and increases crop yields and quality. Weed-suppressing crop rotations are absolutely essential for sustainable organic arable farming. Practical recommendation Basic rules • Implement green manures, such as clover or lucerne, in at least 20 % of the rotation. • Do not grow more than 50 % of cereals with low weed competitiveness in the rotation. Do not cultivate such crops for more than 2 consecutive years. • In fields with prevalent high weed pressure cultivate only crops with high weed competitiveness. Points to consider in case of high weed pressure: • Do not grow grain legumes where perennial weeds are a problem. Late harvest in combination with loose...

Effect of Barley-Legume Intercrop and Major Nutrients on Disease Frequency in an Organic Farming System Organic Eprints
Kinane, Dr. J.; Lyngkjær, Dr. M..
The effect of barley-legume intercrop in an organic farming system on disease incidence was investigated. The legumes were lupin (‘Prima’), faba bean (‘Columbo’) and pea (‘Bohatyr’ and ‘Agadir’). The barley variety was ’Otira’. Diseases were detected on pea and barley. On pea, only Ascochyta blight was observed. When either pea variety was intercropped with barley, the level of Ascochyta was reduced. Net blotch (Pyrenophora teres), brown rust (Puccinia recondita) and powdery mildew (Blumeria graminis f. sp. hordei) (in order of incidence) were monitored on barley between flag leaf emergence and heading. The levels of all three diseases were reduced in every intercrop treatment compared to the barley monocrop. However, this reduction was only statistically...

Effects of cover crops on the overwintering success of entomopathogenic nematodes and their antagonists Organic Eprints
Jaffuel, Goeffrey; Blanco-Perez, Ruben; Büchi, Lucie; Mäder, Paul; Fliessbach, Andreas; Charles, Raphael; Degen, Thomas; Turlings, Ted C.J.; Campos-Herrera, Raquel.
Conservation agriculture is arising as an alternative to conventional agriculture with the aim to have a reduced impact on the environment. This includes the use of cover crops to conserve soil quality by limiting soil erosion, adding organic matter, and enhancing soil nutrient content, as well as water availability, which are all factors that can greatly influence the presence of soil organisms. In the current study, we investigated whether winter cover crops can enhance the persistence of entomopathogenic nematodes (EPN) over the winter season. In a first trial we augmented EPN populations in plots without (bared) and with the cover crops, pea (Pisum sativum) or mustard (Brassica juncea). In late autumn, individual mini-plots in each of the three...

Förderung multi-funktionaler Vorteile von Untersaat-Gemüse-Mischanbau Organic Eprints
Mit dem vorgelegten Projekt soll untersucht werden, ob Mischanbausysteme (=Untersaatsysteme) in der Gemüse-Produktion vergleichbare Erträge sowie Qualitäten erzielen lassen, verglichen zu der herkömmlichen Ein-Kultur-Produktion, inwieweit dies auch zur Reduzierung erforderlicher Zukaufdünger, Pflanzenschutzmittel sowie mechanischer Beikrautregulierung (und damit auch zu geringerem Einergieverbrauch) beitragen kann. Dieses Gemüse-Untersaat-Anbausystem sollte in punkto Umweltbeeinträchtigungen wie auch Profitabilität (wegen Kostenreduzierungen) besser zu bewerten sein. Diese Hypothese soll in einem weiten Bereich europäischer Anbauregionen mit Feldgemüse-Produktion getestet werden. Feldversuche werden angelegt in vier CORE Ländern (Dänemark, Deutschland,...

Kupferminimierungs- und Vermeidungsstrategien für den ökologischen Kartoffelanbau. Teilprojekt B: Ackerbauliche Strategien Organic Eprints
Grabendorfer, Sebastian.
Die Kraut- und Knollenfäule, verursacht durch Phytophthora infestans, führt im ökologischen Kartoffelanbau zu Ertrags- und Qualitätseinbußen und in der Folge zu hohen wirtschaftlichen Verlusten. Gegenwärtig stehen im ökologischen Landbau als einzige effektive Regulierungsmaßnahmen kupferhaltige Fungizide zur Verfügung. Allerdings steht der Einsatz von Kupfer als Pflanzenschutzmittel aufgrund der Anreicherungsproblematik im Boden und möglichen negativer Wirkungen auf Nicht-Ziel-Organismen in der Kritik. Im Rahmen des Forschungsprojekts „Kupferminimierungs- und Vermeidungsstrategien für den ökologischen Kartoffelanbau“ wurden mögliche Ansätze für eine Reduzierung des Kupfereinsatzes identifiziert und bearbeitet. Gegenstand des „Teilprojekts B: Ackerbauliche...
