Blight

 

an injury to a plant caused by intense sunlight or contrasting temperatures. Blights also include diseases caused by certain fungi, for example, Monilia cinerea, and by bacteria, for example, Bacterium amylovorum; such blights are infectious. Injuries caused by the incorrect use of pesticides are often called blights.

Blights result in the withering of parts of the bark, shoots, leaves, and flowers. They often kill plants. Coating tree trunks and thick branches with milk of lime is recommended for the control of sun and heat blights. Infectious blights can be controlled through the use of insecticides, fungicides, or bactericides and by pruning and burning affected plant parts. The instructions for the use of pesticides must be carefully followed to prevent the pesticides from blighting the plants.
