Ramu stunt disease

Plant death and failure of ratoon crops occurs in susceptible varieties.

Symptoms

• Stunting of individual shoots or whole stools.
• Leaves develop small cream-green flecks, which grow to become 2-5 mm long yellow-green streaks.

Spread

• Vectored by the island sugarcane leafhopper (Eumetopina flavipes), which is not present in sugarcane-producing areas of Australia.
• Propagation material can also spread the disease.
