Fire Blight

According to Extension Specialist, Mahfuz Rahman, Fire blight is a major bacterial disease of pome fruit (apple and pear) caused by Erwina amylovora. The disease can infect and kill the entire plant. Most bacteria enter through the blossom and then spread into the vascular system of the shoots and limbs, potentially leading to infection of the entire tree. Depending on the availability of an infection source, susceptibility of the variety and weather conditions in the early spring, damage can range from minimal to extremely severe. In general, it is not uncommon to see some disease incidence in every orchard or backyard in the Mid-Atlantic region.
