Susceptibility of Italian olive cultivars to various Colletotrichum species associated with fruit anthracnose

Abstract

Fruit anthracnose caused by Colletotrichum species is a major disease of olive (Olea europaea) worldwide. In this study, we tested in vitro the susceptibility of eight widely grown Italian olive cultivars and one Spanish cultivar to five Colletotrichum species. The Italian cultivars were Carolea,

Antifungal activity of selected lactic acid bacteria from olive drupes

“…Those isolates were sourced from the collection of the Molecular Plant Pathology laboratory of the Department of Agriculture, Food and Environment, Catania University, Italy, the Colección Española de Cultivos Tipo (CECT), Valencia University, Spain, and ITEM Collection from Istituto di Scienze delle Produzioni Alimentari (ISPA), National Research Council, Bari, Italy. Most of them were characterized in previous studies (El boumlasy et al, 2022; La Spada et al, 2021; Carlos Luz et al, 2021; Migheli et al, 2009; Riolo et al, 2020, 2021, 2022).…”

“…To evaluate the antifungal activity of isolates, LABs were tested in vitro against pathogenic fungi s.l., i.e. Most of them were characterized in previous studies (El boumlasy et al, 2022;La Spada et al, 2021;Carlos Luz et al, 2021;Migheli et al, 2009;Riolo et al, 2020Riolo et al, , 2021Riolo et al, , 2022.…”

Some of these pathogens, such as Alternaria, Aspergillus, Colletotrichum, Fusarium and Penicillium , are responsible for decay of olive drupes and deterioration of oil quality (Angerosa et al, 1999; Baffi et al, 2012; Fakas et al, 2010; Markakis et al, 2010; F. Peres et al, 2021; Romero et al, 2022; Torbati et al, 2014).…”

Secondary metabolites produced byColletotrichumspp. on different olive cultivars

“…Several species of Colletotrichum are responsible for olive anthracnose (OA). Overall, 18 Colletotrichum species have been so far reported to be associated with this disease worldwide (Talhinhas et al, 2018); they vary in virulence and geographical distribution (Moral et al, 2021; Moreira et al, 2021; Riolo et al, 2022; Schena et al, 2014; Talhinhas et al, 2018). Most of these species were segregated from the Colletotrichum acutatum ( C. acutatum s.l .…”

“…species complexes and formally described as separate taxa after the acceptance of multilocus phylogenetic analysis as a taxonomic criterion. Colletotrichum acutatum is the most virulent species; as a pathogen responsible for OA it is widespread in the southern hemisphere and is emerging in several olive growing areas of the Mediterranean macroregion, including Albania, Greece, Italy, Portugal, Spain and Tunisia (Riolo et al, 2022; Schena et al, 2017). Colletotrichum nymphaeae is the dominant Colletotrichum species associated with OA in south-western Portugal and was reported as the second most common species associated with OA, after C. acutatum , in Uruguay (Moreira et al, 2021; Riolo et al, 2022; Talhinhas et al, 2015).…”
