African Violet
Key warning symptoms:
- Ringspots
- Distorted leaves
- Mottle
- Stunting
- Chlorosis
The two pathogens we detect most frequently in African Violets and
other gesneriads are Impatiens necrotic spot virus and Tomato spotted
wilt virus. Both are transmitted by thrips and can cause a number of
symptoms, which can include ringspots and mottle on leaves and brown
rings around the leaf petiole. Other viruses can also cause mottled
patterns, as well as symptoms such as distorted leaves.
One other virus we often find in African Violets is tobacco mosaic
virus, which can be transmitted by people handling plants, by
plant-to-plant contact, or in soil. Watering with cold water can
produce spots and rings that resemble virus symptoms.
