Cucurbitaceae family
PSDMLA
This pathogen occurs in MX
4 Known Hosts
Citrullus lanatus
watermelon
No
PSDLMA-12,RICH ISTA
Pathway not proven. Watermelon is a host of this pathogen. No evidence of seed as a pathway found. Often inferred as seed borne because it is seedborne in cucumber.
Cucumis melo
melon
No
PSDLMA-12,RICH ISTA
Pathway not proven. Some melons can be a host of this pathogen. No evidence of seed as a pathway found. Often inferred as seed borne because it is seedborne in cucumber.
Cucurbita spp.
squash, pumpkin, gourd
No
PSDMLA-1,PSDLMA-7,PSDLMA-11,PSDLMA-12
Pathway not proven. Squash, pumpkin and gourd maybe hosts of this pathogen, but usually are resistant to infection. Pseudomonas lachyrmans was isolated from one squash variety involved in a disease outbreak in Italy (PSDLMA-7). Article needs translation to verify methods. No evidence of seed as a pathway found. Often inferred as seed borne because it is seedborne in cucumber.

Cucumis sativus
cucumber
Yes
PSDMLA-2,PSDMLA-3,PSDMLA-4,PSDLMA-5,PSDLMA-6,PSDLMA-12
Cucumber seed as a pathway has been established and is accepted.
Yes
Culture plate, SDS-PAGE electrophoresis
PSDLMA-6,PSDLMA-7
Various seed treatments and disinfectants have been used with varying success. Fermintation during seed harvest also decreases seed contamination.
