Though found in many US states, the pathogen is usually restricted and localized. Probably Worldwide, though not reported. Disease outbreaks are sporadic and usually related to poor sanitation. Bulbs, floral and greenhouse crops most susceptible to disease outbreaks. No reports of seed as a pathway in vegetables and agronomic crops.
Primarily a pest of ornamentals, woody ornamentals and floowers. Vegetables and agronomic crops reported susceptible to the bacterium are listed below. Transmits primarily through propagation.
