onion, corn, rice, sudangrass, pineapple.
ERWIAN
Probably ubiquitous, causes post harvest rots in vegetables such as tomato, cantaloupe and some berries. Causes diseases in the field in the hosts listed below. Reported in host range studies on other Poaceae species. Most common in warm, wet climatic conditions.
4 Known Hosts
Allium cepa
onion
Yes
CABI CPC,ISF RPLD,ERWIAN-1,ERWIAN-2,ERWIAN-3,ERWIAN-4,ERWIAN-6
Contamination of seed by this bacteria is well documented.
Yes
PCR, Plating on semi-selective media
ISF RPLD,ERWIAN-4,ERWIAN-1
Cultural practices to reduce this pathogen in weeds and thrips are suggested

Oryza sativa
rice
No
CABI CPC
Pathway not proven. CABI cites two research articles indicating that rice seed may be a pathway. However, it is unclear from the articles if the pathogen described is P. ananatis. Rice appears to be a host in the field.

Zea mays
corn
No
ISF RPLD
No references found indicating seed is a pathway. P. ananatis does not cause significant disease in corn. Seed as a pathway may be inferred because it is a pathway in onion.

Sorghum sudanense
sudan grass
No
ERWIAN-5
Pathway not proven. Only one reference found indicating seed may be a pathway. However, seed transmission was not shown in this research. The pathogen was recovered from seed in laboratory tests. Seed pathway may be inferred because seed is a pathway in onion.
Yes
