4.1 Prevention methods for plant protection against diseases in organic agriculture

Encouraging natural enemies and avoid intermediate hosts


In principle, increasing biodiversity in the ecosystem through, for example, flower strips or species-rich revegetation supports the attraction of beneficial insects. These beneficial parasitiods or predators can reduce vectors of pathogens such as aphids or cicadas and thus reduce the likelihood of transmission of viral and bacterial diseases. On the other hand, care should be taken to avoid intermediate hosts of pathogens (e.g.: juniper for european pear rust, Gymnosporangium fuscum).
