The bacterial paddy rice disease of leaf spot is widespread in Kuangtung Province. The loss in yield of the affected paddies is generally 5- 25, but when the disease is serious, the loss may reach above 30. One of the major primary source of infection is the bacteria carrying seeds. The second source is the diseased oil weeds that grow along the edge of the paddies. The soil is not a carrier.
