A foliar blight of bell pepper (Capsicum annuum L.) was observed in two fields in Florida during an extremely wet period in the winter of 1983. In one instance, 90-1009'6 of the foliage was blighted and the plants were severely stunted. A fluorescent-pigmented bacterium was isolated that, when sprayed onto water-congested pepper plants, produced symptoms similar to those observed in the field. The bacterium was negative for levan production, utilization of sucrose, oxidase reaction, and arginine dihydrolase but was positive for potato soft rot and utilization of erythritol, D(-)-tartrate, and DL-lactate. The bacterium was identified as Pseudomonas viridiflava (Burkholder) Dowson.
