Seven species of bacteria are pathogenic to wheat. Only two of these cause economic loss. Pseudomonas syringae pv. syringae can cause severe damage when temperature is moderate and conditions are wet. Xanthomonas campestris pv. translucens is distributed worldwide and causes the most serious bacterial disease of wheat. It is also anticipated to be the most important bacterial disease in tropical areas. The major means of widespread dissemination is seed. Inexpensive methods to control seedborne inoculum are needed. Water is the main means of dissemination within fields. Cultural practices that restrict movement of irrigation water from infested fields are important. More information about survival of bacteria as parasites or as epiphytes on weeds or other crops such as rice are needed to develop control strategies in tropical agricultural systems. Resistance will be a primary means of control
