Widespread distribution. Asia, Africa, Oceania. On sugarcane, lowland pitpit, and other Saccharum species. Occasionally, an important virus disease.
Galls occur on the leaves; leaves are stiff, stunted, and flat-topped (as if chewed).
Spread is by planthoppers, and in planting setts.
Cultural control: use varieties bred for resistance (Fiji and Australia); do not take planting material from affected plants, even if some stalks in a stool look healthy; carefully remove diseased plants as soon as disease seen without spreading insects; collect and burn trash, after harvest.
