COLLHG
Colletotrichum higginsianum is a fungal pathogen that infects Brassicaceae plants like mustard, cabbage, and Arabidopsis, causing anthracnose disease with dark, sunken lesions on leaves, stems, and fruits.
4 Known Hosts
Raphanus sativus
radish
Uncertain

Seed as a pathway for C. higginsianum in Raphanus sativus is uncertain. There are a few publications referencing it as seed transmitted; however primary literature is unavailable, is questioned by other reports, or does not show detailed information on the species and methods used. Only one report (Scheffer 1950) shows 16% seed to seedling transmission.

No
COLLHG-3
Seed is often cited as a means of transmission, but no evidence of a seed pathway was found. Seed has been inferred as a pathway due to possible seed transmission in radish.
