The cabbage  oilseed rape agroecosystem consists of cruciferous crop plants with different levels of productivity and labour intensity. In Switzerland, such crop plants are cultivated mostly in small-scale agricultural settings. Cruciferous crop plants are hosts for a wide range of pest insects and plant pathogens. However, the importance of the damage caused by pests and pathogens varies according to the perceived value of the crop plants. The aim of the present study was to investigate the relationships within the cabbage  oilseed rape agroecosystem. [...] Furthermore, the downey mildew found on cabbage and oilseed rape belonged to the same population. These findings show that the cultivation of cabbage and oilseed rape in small-scale agricultural settings offers optimal conditions for pests and pathogens to spread and establish themselves.
