Symptoms include abnormal development of buds causing a "witches' broom" appearance. Leaves are reduced in size and pods, if formed, can be curved or flat with few developed seeds. Can resemble Machismo or Bud proliferation. Can be transmitted by the leafhoppers Orosius spp and Neosphrosyne orientalis.
