Aggressivität von Fusarium avenaceum, Fusarium solani f. sp pisi und Mycosphaerella pinodes auf Wintererbsen (Pisum sativum L.) unter kontrollierten Bedingungen Organic Eprints
Šišić, Adnan; Bacanovic, Jelena; Bruns, Christian; Finckh, Maria R..
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...

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...

Auswirkungen von Fusarium solani f. sp pisi, Fusarium avenaceum und Mycosphaerella pinodes auf Sommererbsen im Topfversuch Organic Eprints
Bacanovic, Jelena; Šišić, Adnan; Bruns, Christian; Finckh, Maria R..
Foot rot is an important limiting factor in pea production in Germany (Pflughöft, 2008). The disease is caused by a pathogen complex consisting of Ascochyta complex pathogens (Mycospharella pinodes, Phoma medicaginis and Ascochyta pisi) and Fusarium spp. However, little is known about the specificity of single pathogens of the complex and their impact on plant performance. In order to address this problem pot experiments with five isolates each of Fusarium solani f.sp pisi, Fusarium avenaceum and Mycosphaerella pinodes were carried out in controlled conditions. Three weeks after sowing and inoculation disease symptoms were assessed and plant growth parameters measured. All pathogens caused root discoloration and development of disease symptoms on pea...

Das EU-Projekt OSCAR (Optimising Subsidiary Crop Applications in Rotations): Ergänzende Pflanzen zur Systemoptimierung in der pfluglosen Landwirtschaft: Neue Genotypen gesucht Organic Eprints
Finckh, Maria R.; Bacanovic, Jelena; Junge, Stephan; Wedemeyer, Rainer; Schmidt, Jan Henrik; Hallmann, Johannes; Baresel, Jörg Peter.
In diesem Artikel konnte nur ein sehr kleiner Einblick in das Projekt OSCAR gegeben werden. Inspirationen kommen vor allem aus Südamerika, wo die Direktsaat bereits Standard ist. Die erfolgversprechendsten Arten als Zwischenfrüchte und Untersaaten werden von mehreren Projektpartnern gemeinsam mit beteiligten Landwirten in der Praxis getestet. OSCAR wird jedoch zum Projektende noch keine fertigen Lösungen bieten können. Mit dem sich deutlich wandelnden Klima auch in Deutschland werden Boden- und Wasserschutz immer wichtiger. Dazu tragen die Lösungsansätze von OSCAR bei. Es sind aber bereits einige Folgeprojekte entstanden. Dazu gehört vor allem ein Projekt zur Züchtung von Untersaaten unter den Bedingungen der Minimalbodenbearbeitung.

Einflüsse des Ackerbohnenkäfers (Bruchus rufimanus) und von Bodenpathogenen auf Feldaufgang und Ertrag bei bunt- und weißblühenden Ackerbohnensorten (Vicia faba) Organic Eprints
Saucke, Helmut; Riemer, Natalia; Geßner, Christina; Bacanovic, Jelena; Šišić, Adnan; Finckh, Maria R..
We compared field emergence and yield of a white- and a coloured-flowered variety of faba bean (Vicia faba) in relation to Bruchus rufimanus seed damage in a factorial, hand sown mini-plot field experiment. Further manipulating factors at sowing were, foot root rot inoculation with a 4-species Fusarium-mixture, a seed dressing with powdered testa material of the coloured-flower variety and sowing depth. In both varieties Fusarium-inoculation was the most detrimental and significant factor to field emergence and yield, interacting with a concordant B. rufimanus effect. Expectedly, the white-flowered variety was most affected. Tannin-containing testa meal did not reduce or compensate the impact of fungal inoculation and/or B. rufimanus. We hypothesize that...

Fusarium avenaceum - Fuß- und Wurzelkrankheitserreger der Erbse Organic Eprints
Bacanovic, Jelena; Šišić, Adnan; Finckh, MR.
Root and foot rot is economically important disease of peas and is caused by complex of more than 20 different species of soil-borne pathogens. In recent years in Germany, Fusarium avenaceum is emerging as important and devastating pathogen and it is together with several other species, including F. solani, F. oxysporum, F. redolens and Phoma medicaginis among the casual agents of the disease that is commonly referred to as pea root rot complex. In 2012, after severe black frost in February that caused failure of the pea crop, F. avenaceum was isolated in high percentage, 42% of assessed roots. All of tested F. avenaceum isolates caused moderate to severe disease symptoms on pea variety Santana. All of composts as well as endophytic F. equisety isolates...

Kontrolle bodenbürtiger Krankheiten des Fußkrankheits-komplexes an Erbsen mit Komposten Organic Eprints
Bruns, Christian; Werren, Dagmar; Bacanovic, Jelena; Fuchs, Jacques; Heß, Jürgen; Finckh, Maria R..
Soil borne diseases are highly important in organic grain legumes. Suppressive composts are an important measure to control soil borne pathogens in different crops. So far, reports on the foot rot causing pathogens in peas such as Fusarium spp., Phoma medicaginis, Mycospherella pinodes are rare. In our study Phoma medicaginis, Pythium ultimum and Fusarium avenaceum were significantly controlled with yard waste composts demonstrating the principal potential of composts to suppress these diseases. However, the main challenge for organic farmers are to transfer these results to the practise in organic farms. In a field trial with peas 5 and 18 t/ha of compost were applied as broadcast or as strip application while sowing peas with a new developed sowing...

Organic potatoes, reduced tillage and mulch in temperate climates Organic Eprints
Finckh, Maria R.; Bruns, Christian; Bacanovic, Jelena; Junge, Stephan; Schmidt, Jan Henrik.
The experiments with mulching were done in a systems approach comparing potatoes as they are typically produced in Germany with ploughing to a system of non-inversion tillage combined with mulch. As the plots are integrated in two long-term experiments comparing ploughed versus minimum tillage it was not possible to integrate a mulched ploughed treatment or a non-mulched non-inversion tillage due to restrictions in plot size. We tested the effects of mulching in a ploughed system in 2015. There was no late blight but good erosion control (Pict.5) and yields were increased through mulching. Compost effects on the system were so far not clearly visible. It will most likely take several more years of regular applications to start seeing changes in system...

Screening verschiedener Leguminosenakzessionen auf ihre Anfälligkeit gegen wichtige Wurzelpathogene Organic Eprints
Šišić, Adnan; Bacanovic, Jelena; Finckh, Maria R..
Leguminous species could provide multiple beneficial services to agroecosystems when grown as cover crops (CC) and/or living mulch species (LM) in rotations with cereals. However, these benefits can only become effective if the pathological risks are thoroughly assessed and solutions for potential problems identified. In order to assess suitability for inclusion of novel leguminous LM and CC species into the rotations, a total of 62 accessions were screened under controlled conditions for their susceptibility/resistance to major legume root infecting pathogens. Majority of tested plant accessions were highly susceptible to Fusarium avenaceum, and low to moderately susceptible to F. oxysporum and F. solani. Peyronelaea pinodella and Didymella pinodes most...

Shifts in the composition of plant parasitic nematodes under different tillage sytems, living mulch, and compost application Organic Eprints
Schmidt, Jan Henrik; Šišić, Adnan; Bacanovic, Jelena; Hallmann, Johannes; Finckh, Maria R..
Plant parasitic nematodes may cause massive yield reductions in organic farming. Long rotations, often high amounts of weeds and a high frequency of legumes favour parasitic nematodes with a broad host range such as Meloidogyne spp. und Pratylenchus spp. The EU- Projekt OSCAR (Optimizing Subsidiary Crop Applications in Rotations) aims at improving soil conservation through minimum tillage combined with living mulches, cover crops and the use of suppressive composts. An experiment was set up with a rotation of 2-year grass-clover mix followed by wheat and then potatoes. Experimental factors were tillage, cover crops, and compost application. Until now Nematodes were sampled before and after wheat and before potatoes. Population dynamics over time were more...

Suppression of pathogens causing foot rot of pea by application of yard waste compost Organic Eprints
Šišić, Adnan; Bacanovic, Jelena; Bruns, Christian; Finckh, Maria R..
Legume foot and root diseases are mostly caused by broad host-range pathogens. These cannot be managed by rotations alone as often cover crops also are susceptible. Organic amendments such as high quality composts are key management tools for dealing with pathogen pressure. A pot experiment under controlled conditions was carried out to evaluate the suppressive potential of Yard Waste Compost (YWC) against foot rot disease of pea caused by Mycosphaerella pinodes, Phoma medicaginis, Fusarium solani f. sp pisi and F. avenaceum. The spring pea Santana and winter pea EFB33 were grown in sterile sand or sand amended with 3.5 % or 20 % (v/v) YWC as a substrate for three weeks. They were either inoculated at sowing with spore suspensions or left uninoculated....

Unterdrückung der Erbsenfussfäule, verursacht durch Didymella pinodes, Phoma medicaginis, Fusarium solani f. sp pisi und Fusarium avenaceum durch suppressiven Grüngutkompost Organic Eprints
Bacanovic, Jelena; Šišić, Adnan; Schmidt, Jan Henrik; Bruns, Christian; Finckh, Maria R..
Legume foot and root diseases are influenced by complex interactions of site, soil properties, seed health, cropping sequence and climate. Crop rotation, cover crops and organic matter management are the key management tools in the dealing with the increase pathogen pressure. Application of high quality composts and other organic amendments is potential ecologically friendly alternative to fungicide application for control of soil-borne fungal pathogens. In order to evaluate the potential of Yard Waste Compost (YWC) to suppress foot rot disease of pea caused by Didymella pinodes (syn Mycospharella pinodes), Phoma medicaginis, Fusarium solani f. sp pisi and F. avenaceum, a pot experiment was carried out under controlled conditions. The susceptible spring...
