Bacterial Spot

Citrus bacterial spot is only known to occur only under nursery conditions. There are three groups of isolates based on laboratory assays considered aggressive, moderately aggressive, and weakly aggressive. Only aggressive isolates were historically spread in field nurseries naturally by wind-blown rain and overhead irrigation. All strains can be mechanically moved from tree to tree under normal nursery operation. When infected trees are transplanted into groves, the bacterium rapidly dies off and the disease becomes undetectable in a few months. The activity of the citrus leaf miner exacerbates citrus bacterial spot.

Other Common Names

CBS, this however may lead to confusion since citrus black spot uses the same abbreviation.
