Mean crown rot incidence for each treatment is reported as percent mortality, which was calculated by back-transforming the mean arcsine square root disease incidence for each treatment that is reported in parentheses. Mortality data collected at 15, 12, and 16 weeks after inoculation were used for the 2004–05 season, 2006–07 season, and 2007–08 season, respectively.
x Means within the same column followed by the same letter were not significantly different (P = 0.05) according to least square means t tests.
y Means for seasons combined were estimated from fixed effect model parameters, and variances of these means were estimated from treatment × year and
residual variance components.
z For the three seasons combined, the LSD equal to 0.174 was used to compare treatments included in trials all three seasons except the comparison between
azoxystrobin applied at 2 DBI and captan at 1 DAI, where an LSD equal to 0.175 was used. An LSD equal to 0.196 was used to compare treatments included
in trials three seasons to those included for two seasons, and an LSD equal to 0.212 was used to compare treatments included in trials during two
seasons only. For the 2004–05 season, the LSD value of 0.138 was used for all comparisons except those that included treatments azoxystrobin applied at 2
DBI and captan at 1 DAI. Comparisons involving these treatments used an LSD of 0.144 and 0.150 when they were compared to each other.
