zMR = Moderately resistant. Control only needed with fire blight susceptible
rootstocks or under high disease pressure.
S = susceptible. Control usually needed when conditions are favorable for infection.
HS = highly susceptible. Control always needed when conditions are favorable for
infection. These cultivars should receive first priority when control is called for.
