Abstract
Disease avoidance occurs when infection of a host and subsequent disease development are prevented through temporal, spatial, or physical barriers.
Unlike the similar concept of disease escape, disease avoidance, by definition, is under genetic control of the host and is not a random process.
In this study, we have made a preliminary assessment of the period of susceptibility for highbush blueberry cultivars to the mummy berry fungus.
In addition, we have further characterized the infectious period of populations of the mummy berry fungus.
The timing and duration of host susceptibility and pathogen infectivity will be used to describe the coordination between host cultivars and pathogen populations of different phenologies and to predict host resistance due to disease avoidance.
