| Biofumigation is discussed as a potential method of securing tuber yields in organic potato production. Brassicaceae with high contents of glucosinolates are cultivated as cover crops and incorporated into the soil to support the development of isothiocyanates. A pot experiment with soil from two biofumigation field trials was conducted to test biofumigation effects on potato tuber yields, potato leaf necrosis and weed growth. In the field trials different cover crops (Vicia sativa, Raphanus sativus and Brassica rapa) and a control without any cover crop were incorporated into the soil in autumn or spring. Before incorporation in spring soil of the field plots was taken to pots together with one potato tuber. Common cover crop effects could be observed,... |

| 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. |
