Fireblight is a bacterial disease affecting apple, pear, crabapple, hawthorn, and quince. It is a highly contagious disease and spreads quickly between trees in close proximity. Fireblight causes damage to virtually every part of the host tree. It can appear on the trunk, limbs or twigs as a canker. It will make leaves and twigs appear burned or scorched and will cause blossoms to turn brown and appear wet. A tell tale sign is the “shepherds crook” which is created in the branch tips. Fireblight can cause the death of the tree.
