The ragged stunt is caused by a virus transmitted by the brown planthopper. This disease produces several symptoms of leaf malformations, such as ragged and twisting leaves. The leaves of the diseased plant are dark green. Panicles from diseased plants only partially come out, and the resulting grain is empty. The disease is controlled by controlling brown planthoppers, among others, by planting resistant varieties.

A virus transmitted by brown planthoppers causes this disease, and the only host plant is rice. Severely infected plants will become stunted with excessive tillering, giving them a grassy appearance. The leaves of rice plants become narrow, short, stiff, pale green to green, and sometimes have rust spots. Infected plants usually survive to maturity but do not produce panicles. The most susceptible stage of plant growth is at the time of transplanting to pregnancy.
