Bacterial leaf scorch (commonly abbreviated BLS, also called bacterial leaf spot) is a disease state affecting many crops, caused mainly by the xylem-plugging bacterium Xylella fastidiosa. It can be mistaken for ordinary leaf scorch caused by cultural practices such as over-fertilization.

Hosts

BLS can be found on a wide variety of hosts, ranging from ornamental trees (elm, maple, oak) and shrubs, to crop species including blueberry and almond.

Further information: Pecan bacterial leaf scorch

Symptoms

An irregular browning leaf margin which may or may not be bordered by a pale halo.

Symptoms re-occur every year, spreading throughout the tree crown, eventually killing the host plant.

Vectors

Xylem-feeding leafhoppers can transmit the disease bacteria.

Treatment

There are no known effective treatments for BLS, consequently, removal of affected plants is recommended.
