Sugarcane mosaic is a disease caused by sugarcane mosaic virus. Mosaic can cause losses of 30% or more in susceptible varieties. Mosaic disease is characterized by a mottled pattern on the leaves produced by contrasting light green to yellow and dark green patches. The patches are irregular in shape and have diffuse margins. Infected plants appear paler and more yellow than healthy plants. In some varieties, particularly varieties with dark red to purple stalks, the mosaic pattern can be seen on the stalks.
