dfi, days following inoculation; T, time; C, crop; I, inoculation; GGE, Greenhouse–Geisser epsilon; SED, standard error of difference; df, number of degrees of freedom.

A: SED for comparing means for with different levels of inoculation and crop, B: SED for comparing means with the same level of inoculation and crop (C × I) for different times (dfi) of measurement.
