COLLDU
Colletotrichum truncatum is the causal agent of anthracnose on several crops, particularly legumes, causing sunken lesions on stems, pods, leaves, and fruit. The pathogen survives in crop debris and spreads mainly by rain splash and mechanical movement of spores. Seed transmission has been reported in some hosts (particularly legumes), but its significance is host-dependent and not considered universal.
Crops
Capsicum annuum
pepper
No
CABI CPC, COLLDU-9, COLLDU-15, COLLDU-19, COLLDU-20
No references were found, indicating that pepper seed is a pathway for Colletotrichum truncatum. One reference inferred pepper as a host, but the study used C. capsici, which was referred to as C. truncatum and is distinct from the C. truncatum that attacks soybean; therefore, pepper seed is not considered a pathway for this pathogen.
Chemical, cultural
Use disease-free seed, crop rotation, and foliar fungicides as needed.
