Fireblight (due to Erwinia amylovora ) has continued to spread northwards and westwards in UK. In SW England, the disease has been particularly severe in perry pear orchards, causing the loss of many thousands of mature trees, and in cider apple orchards. Cider apple trees are not rapidly killed but crop losses have been severe in some years. The disease has become established in the NW midland counties of England and also in Wales. Outbreaks have occurred as far north as Lancashire just above the administrative line which separates the affected area from the disease‐free (clear) area. Spread has occurred through infections in Crataegus hedges, especially along motorways, and also through movement of infected ornamental species. New legislation is envisaged which will redefine the clear area and increase the protection given.
