Sugarcane gumming disease was first reported in Puerto Rico the 1920s. 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.

enters maize leaves through the stomata and colonises the intercellular spaces. Visible symptoms are long thin lesions that run parallel to the leaf vein and have wavy or jagged margins. Lesions can be yellow, orange or brown and expand over time. When held up to the sun lesions appear translucent

has been reported. Under experimental conditions it can infect sorghum, oats and some grass species. It is not currently a quarantine pathogen in any country, but it has already spread outside its native range and is highly adaptable to different environments.

Leaf streak of maize was first observed in South Africa in 1949. The disease was then observed in
Argentina in 2010 and the USA in 2014. It is now widespread in the USA as well as being found in Brazil, Argentina, Madagascar, South Africa and Zimbabwe.

Secretion of exopolysaccharides leads to gumming and vascular ooze which blocks the flow of water and nutrients through the plant. This leads to wilting and if the stem is cut a thick ooze emerges.
