“…An isolate of Colletotrichum was obtained from diseased fruit in a commercial field in Campinas County in Sao Paulo State, Brazil. A single‐spore culture was obtained, which was phylogenetically identified as C. gloeosporioides by multilocus sequencing of ITS, GAPDH, ACT, CHS‐1, TUB2 and CAL genes (Bragança ) according to the method of Weir et al. ().…”

In this study, we determined the influences of temperature, wetness period and guava fruit age on infection caused by Colletotrichum gloeosporioides. Optimal temperatures in vitro for germination, appressoria formation and melanization were 22.7, 20.6 and 23°C, respectively. In vivo, the optimal temperatures for germination and appressoria formation were 22.5 and 23°C, respectively. Values for germination, appressoria formation and melanization were higher as the wetness period increased. There was no difference in conidial germination and appressorial formation on fruit of different ages. On the surface of 10‐, 35‐ and 60‐day‐old fruit, despite the high percentage of appressorial formation, there was no development of the penetration peg. Penetration pegs were only observed on the 85‐ and 110‐day‐old fruit. Thickness of the cuticle, size and architecture of epidermal and parenchymal cells, as well as the content of phenolic compounds changed as the fruit ripened.

“…The GLS is caused by Colletotrichum spp. The Colletotrichum genus was reclassified Weir et al, 2012), and based on this new classification were described species causing the disease belonging to two complex, Colletotrichum acutatum complex and Colletotric hum gloeosporioides complex (Bragança, 2013). The disease has been controlled by applying dithiocarbamate fungicides in particular (Mancozeb, Metiram and Propineb), which show a high index of control (IC) at the beginning of the vegetative cycle of the apple tree (IC > 80%) and that is median at the end (IC > 70%) of each season, when the pressure inoculum increases.…”
