are contaminated with the fungus in the field, but the disease commonly occurs
at the packing house or in transit. Decay occurs around the stem end [Picture
] and advances in streaks down the side of the fruit. There is no fungal

in fungicide solutions before placement in de-greening rooms. Promptness in
handling and shipping, as well as refrigeration during transit, will minimize
losses.
