Minimising strategies for copper pesticides in organic potato cultivation

Summary in the original language of the document

It can be stated that also in future a successful copper minimization strategy based on the use of all preventive measures, the further reduction of copper application rates and the development of alternative pesticides. First results of the EU project COFREE (Copper Replacement Strategies) have shown, that the high safety effect of copper-based products is difficult to achieve by alternative products. The short, medium and long-term measures for the implementation of copper minimization strategy are described in this paper. The future development potential of the measures to minimize copper in organic potato production is assessed.
