Benchmark of current state of the art

Growth of EU organic potato production is likely because of increasing consumer demand, but crop profitability may decrease. Late blight is a major but variable problem for many growers. Diverse strategies are used to stabilise yields and income but not all growers use available technology. Where permitted, copper fungicides are relied upon for control to maintain yield and quality as alternatives are usually ineffective. Almost two-thirds of copper-fungicide users expected organic potato production to decrease with serious consequences if it is banned.

However, region-specific optimization/integration of technologies should improve yields and yield stability with less dependence on copper. Some growers could achieve this simply by adopting existing production strategies i.e. state of the art technology or improving efficiency. Key factors identified in need of further development, exploitation and evaluation under various regional conditions were:
- Crop resistance management strategies
- Agronomic strategies
- Soil fertility management
- Novel crop protection strategies.

Dissemination of the resulting know-how/ novel technologies from the research programme would increase success and future stability of organic potato production considerably with less reliance on copper compounds.
