Most years in the UK are too cold at blossom time for infections to occur and the disease is usually of relatively minor importance. Severely attacked trees appear to have been scorched by fire. Under favourable conditions the infections spread rapidly down the inner bark at up to 5cm (2in) per day, staining the cambium a foxy reddish-brown colour. Infections occur when the bacterium gains entry to the inner bark, usually via the blossoms, and it is spread by wind-blown rain and also by insects including bees. In warm, wet and windy weather in spring, bacteria ooze out of the cankers. Suspected cases in these areas should be reported to the relevant plant health authority.
