Lastly, we investigated the area of the lesions as a percentage of
the total leaf area, which is equivalent to disease severity. As shown
in Fig. 3 and Table 1, there was no significant difference in the
control of anthracnose between B. subtilis HK-CSM-1 and ITA
(p < 0.01). Furthermore, the percentage of leaf area covered by
lesions indicated significant linear correlation (r ¼ 0.95038,
p < 0.05) with the number of lesions. This again suggests that the
penetration stage is critical in the effective control of anthracnose
in ginseng. These observations also confirm the veracity of visual
assessments.
