Bacterial leaf streak is an emerging disease in the Prairies. In 2023, Michael Harding’s provincial team conducted a province-wide survey to see where it is being found. Most of the infections were in Vulcan, Taber and Newell counties.
However, one positive field was found at a more northern location, in Athabasca County. If the survey did not find bacterial leaf streak in your area, do not assume it is not present. Infection is highly impacted by weather. Warm and humid conditions favour the infection and bacteria can double multiple times within a
day.
