The occurrence of diseases in rainfed lowland rice differs not only among countries but also in different seasons within a country. Excess or inadequate rain associated with rainfed lowland environments is conducive to disease at different crop growth stages. Sheath blight, bacterial blight, tungro, ragged stunt, sheath rot, brown spot and blast appear to be the most important disease in the five largest rainfed areas in Asia. Tungro, however, has not been reported in Burma and Vietnam. No information is available on how much yield loss and damage are caused by single or combined diseases in the region. Some cultural practices that farmers exercise may also have beneficial effects on reducing pathogen populations. Any recommendation for disease management should be validated at several sites under different environmental conditions.
