A common problem
of African Violets is a Fungal attack of Phytophthora, Pytkium, , and/
or Cylindrocarpon, which will cause the crown and roots to become soft.
The outer leaves may drop and the central leaves may turn black over time.
Prevention
includes using sterilized plastic pots which cannot harbor disease. Use
only sterilized potting soils. A soil formulated for African Violets may
be beneficial. Plant African Violets with the crown above the soil level.
Water them sparingly. If you touch infected plants, wash your hands before
handling healthy plants.
Treatment:
Benomyl ("Benlate") is a systemic fungicide used to combat these and other
fungal diseases. Use it according to directions on the container.
