Blight
Blight is a rapid and complete chlorosis, browning, then death of plant tissues such as leaves, branches, twigs, or floral organs. Accordingly, many diseases that primarily exhibit this symptom are called blights. Several notable examples are:
Fire blight
In the early 1800s, "E. amylovara" was the first bacterium that could be used in experiments to demonstrate that it did indeed cause disease in plants. It is accepted that this destructive crop bacterium had initially originated in North America. Today, "E. amylovara" can currently be found in all the provinces of Canada, as well as in some parts of the United States of America; states include Alabama, California, Colorado, Connecticut, Georgia, Illinois, Maine, Maryland, Massachusetts, Michigan, New York, North Carolina, Ohio, Oregon, Pennsylvania, Texas, Utah, Virginia, Washington, West Virginia and Wisconsin. Other American countries of its occurrence include but are not limited to Mexico and Bermuda. On the African continent, "E. amylovora" has been confirmed in Egypt.
