Taro (Colocasia esculenta) foliage that came into the clinic tested positive for a potyvirus. We suspect Dasheen mosaic virus (DsMV) is the potyvirus at play. The chlorotic feathering along the veins is a characteristic symptom of this viral disease. #potyvirus#araceae

Tobacco mosaic virus (TMV) symptoms on a tomato leaf. TMV is spread through contact by hands, tools, and/or seeds. It is advised to remove the infected plants from your garden (far away from your healthy plants). #tobamovirus

Herbicide drift injury on field-grown tomato plants. Viral diseases can be mistaken for the symptoms of leaf distortion and cupping caused by herbicide injury. These specific symptoms resemble damage from a synthetic auxin herbicide class. There is no cure for this disorder.
