On other hosts, ringspots, purple to black lesions on leaves and stems, flower color breaking, stunting, death of terminals, and wilt may occur. The stage of growth can also influence symptom development. For many hosts, symptoms are not well known or are not described. However, in some commonly infected crops, symptoms can be diagnostic. Gloxinias infected as young plants develop necrosis of the central leaves, resulting in collapse.
Older gloxinias develop necrotic ringspots on the foliage, as well as necrosis along the veins.
On exacum, the virus causes tan to dark brown cankers on stems. Reiger begonias develop necrotic ringspots, mosaic, and necrosis of the leaf veins. Symptoms on impatiens and New Guinea impatiens include stunting, leaf distortion and blackened spots or rings on foliage and stems. In some cases, terminals will die and the entire plant may collapse. As with other virus diseases infected plants may remain symptomless for a period of time.
