As with corn, long thin leaf lesions are seen. They may be orange, yellow, brown, grey or white depending on the stage of infection. As the disease progresses the bacteria spreads to the stem via the vascular system. Secretion of exopolysaccharides leads to gumming and vascular ooze which blocks the flow of water and nutrients through the plant.
Bacterial leaf streak is a major bacterial disease of wheat. Yield losses are normally less than 10%, but can be up to 40%. The loss in yield is due to lower weight of the seed rather than lack of production. Risk of damages due to bacterial leaf streak is variable, but should not be overlooked because there is always a chance of an epidemic.

Stewart's wilt is a bacterial disease of corn caused by the bacterium Pantoea stewartii. The disease is also known as bacterial wilt or bacterial leaf blight and has been shown to be quite problematic in sweet corn. [1] [2] The causal organism is a facultatively anaerobic, gram-negative, rod-shaped bacterium. [3]
Xanthomonas translucens is a species of phytopathogenic bacteria. It is the causal agent of bacterial leaf streak in of wheat and cereal crop. The bacterium is transmitted as a seed-borne pathogen. The transmission rate is very low but ensures serious outbreaks in the field under suitable conditions.

Bacterial spots on monocotyledonous plants with parallel leaf veins have a streak or striped appearance. [7] The most obvious symptom of bacterial leaf spots are the blackening of the spots after infection. Eventually older lesions dry out and become papery in texture. [12]
