    Based on the monitoring, following changes were made to CAA WG recommendations for Phytophthora infestans in 2023 (link) compared the previous year:
    • Apply CAA fungicides always at recommended dose rates
    • Apply CAA fungicides using not more than 2 consecutive applications
    • Apply CAA fungicides preferably in mixtures with effective partners belonging to different modes of action
    • An effective partner for a CAA fungicide is one that provides satisfactory disease control when used alone at the mixture rate
    • Good agricultural practices must be considered to reduce source of inoculum, disease pressure and resistance risk, e.g. consider to plant resistant varieties and refer to disease prediction models

    In regions with reported cases of resistance:

    • CAA fungicides must be used in mixtures, with not more than 2 consecutive applications
    • In case mixtures cannot be applied for regulatory reasons, apply CAA fungicide in strict alternation
