CLADCU
Widespread in many cool, temperate regions of the world. This pathogen is known to occur in China.
4 Known Hosts
Cucumis sativus
cucumber
Yes
CLADCU-1,CLADCU-2,CLADCU-3,CLADCU-6,CLADCU-7
The pathogen has been found on seed, especially in early publications. Seed borne inoculum appears to be relatively minor, the pathogen commonly survives in the soil and debris. Seed quality programs have greatly reduced inculum associated with seed and inoculum in soil debris more common.
Seed surface-disinfestation with 0.5% sodium hypochlorite for 10 min to decrease all fungal contamination
Resistance in known. Seed quality programs have effectively controlled seed inoculum.

CLADCU-1,CLADCU-2,CLADCU-3,CLADCU-4,CLADCU-7
Pathway not proven. Though seed is often listed as a pathway, there is little evidence that seed is a pathway for this host. Seed-borne inoculum appears to be of minor importance and it is often found in soil debris. Cladosporium spp. on pumpkin seed, has been reported, but it is unclear if the it was identified to species and assumed Cladosporium cucumerinum was the species observed. Seed transmission was not proven and was externally associated with the seed.

CLADCU-1,CLADCU-2,CLADCU-3
Pathway not proven. Though seed is often listed as a pathway, there has been no research or literature found showing seed is a pathway for this pathogen on this host. Seed pathway may be inferred because the pest can be associated with seed in Cucurbita spp. and C. sativus.
