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.

A. alternata has been reported on pea but it is considered a saprophyte of pea plants and seed.. A. alternata has been found on seed, in laboratory surveys but, no references were found indicating seed transmission.

Didymella pinodes (M. pinodes in most literature) has a small host range but primarily affects peas where it is of high economic importance.
Main: pea

Didymella pinodes is the main causal agent of ascochyta blight, a severe fungal disease affecting peas globally. Pea seeds serve as a documented transmission pathway for D. pinodes, with the pathogen surviving in seeds for up to four years. Disease transmission occurs through water, air, soil, plant debris, and seeds. Seed transmission rates of M. pinodes vary with temperature, reaching 100% at 15°C, compared to 61.5% at 18°C and 70% at 25°C, indicating environmental conditions influence its spread.

Captan and thiram, applied as dry powders to infected pea seeds, effectively reduced transmission. Removing plant debris which can act as a host. Performing timely crop inspections. Use disease-free seeds.
