COLLHG
Colletotrichum higginsianum is a fungal pathogen that infects Brassicaceae plants like cabbage, and Arabidopsis, causing anthracnose disease with dark, sunken lesions on leaves, stems, and fruits.
Crops
Brassica juncea
mustard
Not a host
COLLHG-9, COLLHG-10, COLLHG-11
Mustard has been cited as a host based on COLLHG-9; however, this publication does not confirm such a claim, and Brassica juncea has only shown symptoms under artificial inoculation. Therefore, it does not meet the ISPM 5 definition of a host.

Brassica oleracea
broccoli, cabbage, cauliflower, kale
No
COLLHG-4, CABICPC, ISFRPLD
No evidence found indicating that seed is a pathway for Colletotrichum higginsianum in Brassica oleracea.
Brassica rapa
chinese cabbage, turnip
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.

Raphanus sativus
radish
Uncertain
COLLHG-3, RICHISTA, COLLHG-6, COLLHG-7, COLLHG-8
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.
