Evaluation and systematisation of innovative strategies for controlling the yellow wilt
For several years the occurrence of the yellow wilt in Germany and other European countries like France and Italy is a big problem in the cultivation of lamb’s lettuce which can even lead to existence-threatening dimensions for producers. The symptoms of the yellow wilt occur in open field production as well as in covered production systems, especially in glasshouses. So far there are no strategies to control the yellow wilt in a sustainable and long-term way, and also its causes remain unexplained. The objectives of the operational group (OG) should be to find an innovative solution for the problem of the yellow wilt on lamb’s lettuce in Hesse without the application of chemical herbicides and to establish a think-tank and communication platform concerning the treatment of the yellow wilt. In the future a constant, constructive and practice-oriented exchange of knowledge and solution approaches should take place to adapt to continuously new experiences and changed production conditions.
In the course of the innovation project, two effective control strategies were identified, solarization and soil damping-off, which avoid the use of chemical pesticides. Soil analyses helped to narrow down the cause identification. Although no specific pathogen was identified, it was confirmed that the cause was soil-borne and of biological origin. The analytical results indicate that a pathogen complex is involved. Furthermore, with the help of the formation of the OG, a network was generated through a continuous exchange with the practice, the consultancy and the industry, which constantly communicates the current developments and the results of the project. By recognizing that the pathogen complex is soil-borne, measures can be taken at an early stage to prevent the spread of the pathogen to the areas belonging to the farm. These include appropriate hygiene measures as well as land swapping with other crops grown on unaffected land.
