Symptoms of Calibrachoa mottle virus (CbMV) include leaf yellowing, leaf spots and dieback. Plants that show yellowing can be mistaken for iron deficiency. Symptoms of Calibrachoa mottle virus develop when plants are stressed.
CbMV is transmitted mechanically in sap and by propagation. No insect vectors have been found to date.
Once a plant is infected with a virus, it cannot be cured. Management includes discarding and destroying infected plants, including roots.
