Rice cultivation is the most important agriculture in Taiwan. Several bacterial diseases could be found in Taiwan. Among them, bacterial blight（Xanthomonas oryzae pv. oryzae）, bacterial leaf streak （Xanthomonas oryzae pv. oryzicola）and grain rot ( Burkholderia glume ) were the most significant and caused great economic losses in Taiwan. Bacterial leaf blight is one of the devastating disease of rice, which is also known worldwide. There are three types of symptoms : leaf blight, “kresek” and pale-yellow in Taiwan. Now the disease is prevalent and is responsible for 6 – 60% yield reductions depending upon its severity. Leaf streak is mainly occurred in Asian countries, northern Australia, and West Africa and is responsible for 10 – 60% yield reductions. Grain rot of rice is a seedborne disease and in severe case could cause severe loss while in nursery bed. These bacterial diseases might be transmitted through contaiminated seeds, rain splash, irrigation water, insects and culture practices. Bacterial diseases are long known difficult to manage and resistant varieties are the most effective tool to control. However, several measures such as seed quarantine, good field hygiene, and pesticides application could provide ideal outcome. In the coming future, to develop environmental friendly control strategies for organic rice growers and to develop technologies for good nursery bed hygiene are urgently needed.
