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... |

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... |

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... |

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... |

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... |

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... |

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... |

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... |
