Colletotrichum Species Complexes Associated with Crops in Northern South America: A Review

Colletotrichum genus comprises a high number of plant pathogens causing anthracnose disease in different tropical and non-tropical crops. We aimed to review northern South American studies in the online SCOPUS database to: create a taxonomically updated list of the species complexes found in the region, describe their most important phytopathological characteristics, revise the methods used in the region to control disease, and discuss the role of fungus as a plant endophyte. A total of 19 Colletotrichum species within five complexes—acutatum, boninense, gigasporum, gloeosporioides, and orbiculare—have been reported in northern South America. Few studies have been conducted, particularly in Peru and Ecuador, despite the diversity of Colletotrichum hosts cultivated in the region. Important information can be extracted from our review: species do not appear to show host specificity, although some isolates show host preferences, certain plant species can host several Colletotrichum species, some studies show the importance of using plant extracts to control the disease, but biological control using microorganisms is certainly an open area of research in the region. In northern South America, only a few hosts have been reported to harbor Colletotrichum as endophyte, and the potential of these endophytes as biological control agents has not yet been explored.

Colletotrichum acutatum is one of the causal agents of anthracnose in several crops, and of post-flowering fruit drop (PFD) in citrus and key lime anthracnose (KLA). The pathogen normally attacks flowers, causing lesions only in open flowers. Under very favorable conditions, however, it can also affect flower buds and small fruits, causing complete rotting of the fruit and a premature fall, resulting in major economic crop losses. We isolated endophytic fungi from Tahiti lime to evaluate its diversity, verify its antagonistic capacity against the phytopathogen Colletotrichum acutatum C-100 in dual tests, and evaluate the ability of various endophytic agents to control flowers with induced anthracnose. 138 fungal isolates were obtained from 486 fragments of branches, leaves, and fruit; from which 15 species were identified morphologically. A higher isolation frequency was found in branches and leaves, with a normal level of diversity compared to other citrus species. Of the 15 morphospecies, 5 were trialed against C. acutatum in antagonism tests, resulting in a finding of positive inhibition. 2 endophytic fungi from the antagonism tests demonstrated high inhibition of the phytopathogen, and were thus used in in vivo tests with Tahiti lime flowers, applied in a spore solution. Spore solutions of two molecularly identified species, Xylaria adscendens, and Trichoderma atroviride, reduced the lesions caused by the phytopathogen in these in vivo tests. The finding that these endophytes react antagonistically against C. acutatum may make them good candidates for further biological control research in an agroindustry that requires environmental sustainability.
