It is recommended that one of these fungicide treatments be
included if fruit must be dipped in a scald inhibitor.
If fruit do not need to be treated for scald inhibition,
prompt movement into storage with rapid cooling and no
fungicide treatment is another option.
2 A rate of 5 oz in 25-100 gal may be used as a
dilute application or dip for control of blue mold and gray
mold.
