At PARC, decay was severe and over 95% of control fruit were infected. Because infected fruit were not removed periodically as in Hood River, gray mold was quite advanced, and the type of infection (stem end, calyx end, or puncture) could not be determined. None of the treatments affected total gray mold (Table 2). Naturally occurring snow-mold rot caused by an unidentified basidiomycete infected over 42% of control fruit and was significantly (P = 0.001) reduced by all hexanal and 1-MCP treatments
(Table 2). Naturally occurring blue mold caused by P.expansum increased significantly (P = 0.001) in both treatments containing hexanal while 1-MCP alone had no effect(Table 2).
