The Septoria leaf spot on Viola patrinii was very commonly found in the end of June 1992 at the experimental plot of Gangwon-do Agricultural Research & Extension Services. The disease was also common in the end of October, suggesting that the disease may start to occur in May and continue to the life of the plant. This plant species is expected to be used for ground cover and ornamental purpose in Korea. Since the leaf lesions are generally large and expanded to cause leaf blight in the later stage of disease development, the Korean name of this disease is suggested as 'Hin-muni-byong' which means literally 'white-lesion-disease'
