Eleven races of the pathogen have been identified. Pea pathogenic F. oxysporum are common in soils growing pea. They are efficient colonizers of pea roots and often cause seedling death prior establishment. This pathogen is often found with other root and wilt pathogens of pea.

FUSAOPI-4,FUSAOPI-5,FUSAOPI-6,
Pathway not proven. Although references may indicate that seed can be a pathway, direct evidence is lacking or references cite work from 1932. Laboratory testing of seeds have found F. oxysporum on seed but either pathogenicity was not proven or seed transmission was not proven. Soil borne fungi seems to be most important, especially when other root rot or wilt pathogens are present.
