Estimates of the optimum corrected basic infection rate (RcOPT) for eight Colletotrichum clades, latency period under favorable conditions for epidemics (p), infectious period under favorable conditions for epidemics (i), and publications reporting disease progress curves on a susceptible host variety used to calculate the apparent infection rate (r).

RcOPT and r were estimated following Sun and Zeng (1994). Values of p were defined based on studies on latency reported in Table 5 . Irrespective of the clade, the value of i was set at 28 days based on King et al. (1997).
