Albugo tragopogonis (Pers.) Gray 1821

Notes

Albugo tragopogonis is common on a number of indigenous and introduced herbaceous host plants belonging to Compositae. It was of minor economic importance; in 1960 it became common on Gerbera sp. especially when grown in nursery beds. Little if any control is obtained by spraying infected plants with fungicides, but varieties of Gerbera sp. have now been selected that are resistant to white rust (Say, 1963). It occasionally attacks seedlings of cineraria (S. cruentus).
