Monitoring is required to detect and estimate the sensitivity status of pathogen populations to fungicides for the effective control of diseases in a setting of sustainable disease management. Several biological methods are available to detect and to quantify the emergence and evolution of fungicide resistance in obligate parasites in the vineyard such as Erysiphe necator and Plasmopara viticola. To perform good monitoring, particular attention must be paid to the sampling in the vineyard that will serve to determine baseline and discriminant doses. This chapter first describes the methods used to study fungicide resistance in the field and then compares monitoring results for various fungicides and the role of pathogen diversity. This information will help users to choose the most suitable method and to manage resistance.Read less <
