“…Colletotrichum gloeosporioides sensu stricto as a causal agent of avocado fruits anthracnose has only been reported recently in Turkey [ 48 ]. In addition, C. gloeosporioides sensu stricto was not present in tropical fruits tested in Laos and Thailand [ 49 ].…”

The filamentous Ascomycota Colletotrichum gloeosporioides sensu lato is a fungus that has been reported worldwide as a causal agent of anthracnose disease in avocado and other crops. In Mexico, this species affects fruits from an early stage of development in the orchard until the post-harvest stage. Although fungicides are continuously applied to control Colletotrichum species, pericarp cankers and soft rot mesocarp in fruits are still frequently observed. Considering the lack of a precise description of the causative agent, the aim of the current study was to determine the pathogens involved in this symptomatology. Twenty-four isolates were consistently obtained from the pericarp of avocado fruits cv. “Hass” collected in the central avocado-producing area of Mexico. Morphological features such as colony growth, conidia size, and mycelial appressorium were assessed. Bayesian multilocus phylogenetic analyses were performed using amplified sequences of the internal transcribed spacer region of the nuclear ribosomal DNA; actin, chitin synthase, glyceraldehyde-3-phosphate dehydrogenase partial genes; and APn2-Mat1-2 intergenic spacer and mating type Mat1-2 partial gene from the nine selected isolates. In addition, fruits were inoculated with a conidial suspension and reproducible symptoms confirmed the presence of Colletotrichum fructicola in this area. This pathogenic species can now be added to those previously reported in the country, such as C. acutatum, C. boninense, C. godetiae, C. gloeosporioides, and C. karstii. Disease management programs to reduce the incidence of anthracnose should include C. fructicola to determine its response to fungicides that are routinely applied, considering that the appearance of new species is affecting the commercial quality of the fruits and shifting the original population structure.

“…Before the use of multiple gene phylogeny for the identification of Colletotrichum spp., C. gloeosporioides sensu lato was the most common species found in association with avocado anthracnose, followed by C. acutatum sensu lato [84]. However, based on molecular analysis, C. gloeosporioides was also reported as the causative agent of avocado fruit anthracnose in Mexico [85], Mersin Province, Turkey [88], and Ghana [90]. Hunupolagama et al (2015) [86] identified C. gigasporum as a causative agent of avocado anthracnose in Sri Lanka based on four markers, ITS, actin (ACT), GAPDH, and β-tubulin.…”

In tropical fruit crops, anthracnose is mainly caused by species belonging to the fungal genus, Colletotrichum. These phytopathogens can infect several parts of the fruit crops; however, infection during postharvest or ripening stages is responsible for major economic losses. Due to the formation of black to dark brown sunken lesions on the fruit surface, anthracnose reduces fruit quality and marketability. Among the most common tropical fruit crops susceptible to anthracnose are mango, papaya, banana, avocado, guava, and dragon fruit; these are economically relevant products in many developing countries. It is important to document that the newly recorded Colletotrichum spp. associated with fruit anthracnose can infect multiple hosts, but some species may be host-specific. By using multiple markers, many phylogenetic species of Colletotrichum have been reported as anthracnose-causing pathogens. Taking into account that disease management strategies strongly rely on adequate knowledge of the causative agents, updated information on Colletotrichum species and the hazard posed by the most recently identified species in tropical fruit plantations and harvested fruits becomes vital. Besides, the newly recorded species may be important for biosecurity and should be listed as quarantine pathogens, considering that tropical fruits are traded worldwide.

“…Indeed, Colletotrichum gloeosporioides and Colletotrichum acutatum are distributed worldwide on a number of hosts such as kernels (Ogawa and English, 1991;Adaskaveg and Hartin, 1997;Förster and Adaskaveg, 1999), avocado (Freeman, 2000;Akgül et al, 2016), peach (Adaskaveg and Hartin, 1997;Zaitlin et al, 2000), blueberries (Smith et al, 1996;Schilder et al, 2001;Yoshida and Tsukiboshi, 2002), citrus (Zulfiqar et al, 1996;Timmer and Brown, 2000;Benyahia et al, 2003), mango (Fitzell, 1979;Arauz, 2000), olive tree (Martin and García-Figueres, 1999;Benyahia et al, 2003;Chattaoui et al, 2016;Msairi et al, 2017), while Colletotrichum fragariae has a very narrow range of hosts (Mackenzie et al, 2006). A typical anthracnose symptom on cultivated strawberry caused by C. acutatum and C. gloeosporioides was reported in Egypt (Embaby et al, 2009).…”

The evolution of anthracnose symptoms on the aerial part (leaves, stems and strawberries) of three varieties Fortuna, Camarosa and Festival of strawberry plants inoculated with the conidial suspensions of Colletotrichum acutatum and Colletotrichum gloeosporioides isolates was followed. The severity index and infection coefficients increased in function of time. Seven days after inoculation they were low not exceeding 13.43% and 43.33, but they increased four weeks after inoculation, respectively, to 37.96% and 99 on strawberry plants of the Camarosa variety, 54.44% and 105 on those of Fortuna and 51.12% and 85 on those of Festival. At the sixth week, the severity index and infection coefficients became very high, reaching respectively 100% and 408 on Fortuna plants inoculated with C. gloeosporioides isolate (Coll3) followed by Coll2 (89.28%-300), Coll1 (86.66%-378) and Coll4 (80.45%-198) of C. acutatum species. Similarly, the isolate Coll3 caused fruit rot; the percentage of rotten strawberries was 100% on Fortuna variety, 83.33% on Festival and 70.25% on Camarosa. A positive re-isolation of the tested Colletotrichum isolates has been noted from leaves of strawberry varieties and negative from crowns or the roots. A significant to moderate reduction in fresh and dry weights of the aerial part and roots was noted in inoculated strawberry plants compared to the control.
