Fire blight is the most dangerous disease on apple in the north-west of Iran (Azerbaijan province). Fire blight is caused by the bacterium Erwinia amylovora and affects over 130 plant species in the rose family. In the east Azerbaijan province Fire blight is a destructive bacterial disease of apples and pears that kills blossoms, shoots, limbs, and, sometimes, entire trees. Once the bacteria colonize the first few open blossoms, pollinating insects rapidly move the pathogen to other flowers, initiating more blossom blight.
With GIS, researchers were able to view the area of the province that climatic conditions were suitable for spreading and infecting the orchards. The results of this study showed that regions of west and north-west of province are of high fire blight risk.
