The purpose of the use guidelines for AP containing products is to maintain the sensitivity in the target pathogens and to prevent crop losses due to resistant pathogen populations.
- For grey mold and apple scab control, specific guidelines have been developed. In general, where different AP-containing products are used in one season, the cumulative number of applications with cyprodinil-, pyrimethanil- or mepanipyrim-containing products must not exceed the maxima as mentioned below.
- For sound resistance management, good agricultural practices, including phytosanitary measures and crop protection, should be followed not only in commercial practice, but also in nurseries.
- The use recommendations were reviewed during the meeting on January 17th, 2022. The Botrytis and Venturia guidelines have not been changed.
- For all other pathogens and crops, specific guidelines are not yet regarded to be needed. However, the maximum number of applications should be limited and should not exceed more than 50% of all treatments.
