In the DOK long-term field trial in Switzerland comparing bio-dynamic, bio-organic, and conventional farming systems, the occurrence of Fusarium species and Microdochium nivale on grains of wheat was investigated from 1997 to 2003. Although no differences between the farming systems were found, the previous crop, the fertilisation level, and the year significantly influenced the disease incidence. In 2003, the effect of the pre-crops potatoes versus silage-maize on fusaria was compared. As expected, the incidence of fusaria was significantly higher after maize compared with potatoes. However, the main responsible species was not F. graminearum but F. poae. This species is known for the production of hazardous toxins. A greater input of fertiliser resulted... |

In a long-term trial in central Switzerland, yield and health of winter wheat was examined under organic, extensive and intensive management. In the organic cropping system, soil was ploughed and fertilised with cattle dung. In the extensive system, soil was cultivated ploughless and dung was supplemented by mineral fertiliser. Herbicides were used, but no growth regulators or fungicides. In the intensive system, soil was ploughed and manure was based on cattle dung and mineral fertiliser with 20 % more nitrogen than in the extensive system. For plant protection, herbicides, growth regulators and fungicides were used. In the period from 2004 to 2007, average winter wheat yields of the intensive and the extensive crop management system exceeded... |
