and 1-MCP + hexanal significantly (P = 0.003) reduced disease
incidence. Naturally occurring Phacidiopycnis rot caused by
Phacidiopycnis piri also was reduced by the 1-MCP and 1-
MCP+ hexanal treatments (P = 0.013) but not by hexanal alone
(Table 1). None of the treatments affected the incidence of calyx
end or puncture gray mold, but stem end gray mold was reduced
(P = 0.001) by 1-MCP and 1-MCP + hexanal (Table 1). There
was no difference between the 1-MCP and 1-MCP + hexanal
treatments for any decay.
