Begonia

Key warning symptoms:

* Rings
* Mottle or mosaic
* Stunting
* Deformation
* Stem necrosis

Impatiens necrotic spot virus, the pathogen most often detected in begonias, causes many different symptoms including dead areas on stems, mottled or mosaic patterns, lines, ringspots, or yellow, white or brown spots. The closely related tomato spotted wilt virus also causes varying symptoms. Both viruses are transmitted by thrips and by propagating infected plants.

Begonia yellow spot, caused by Tobacco ringspot virus, is a disease that causes yellowish to white spots and yellow mottled patterns. Symptoms can resemble natural variegation. The virus can be transmitted by nematodes in soil or by propagating infected plants.
