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:
Pantoea agglomerans
Research has shown that "Pantoea agglomerans" can serve as a plant pathogen competitor for the management of plant diseases. Fire blight, a plant disease caused by bacterium "Erwinia amylovora," is commonly found in pear and apple crops. After coming in contact with "Erwinia amylovora", "Pantoea agglomerans" produces antibiotic properties that are toxic to the fire blight-inducing bacterium. It has been identified that it is possible that habitat modification or exclusion may also play a role in the effectiveness of the antibiosis of the fire blight biological control.
