Ramu stunt disease
The Ramu stunt disease is a disease of the sugarcane widespread throughout Papua New Guinea, but not detected in Australia. Eumetopina flavipes, the island sugarcane planthopper, is a species of planthopper present throughout South East Asia which is a vector for the disease.
It was first detected in the 1980s. It is thought to be either of viral origin or associated with a Phytoplasma bacterium.
