“…Controlling olive anthracnose is a challenging task due to its high dependence on climatic conditions (temperature, humidity) for its spread and growth [ 13 ]. In general, the methods employed to manage olive anthracnose involve integrated approaches that combine various means and tools.…”

“…The direct control methods and tools for managing olive anthracnose also include the application of natural products and biocontrol agents, which have been increasingly utilized in recent times [ 13 ]. A group of biocontrol agents that could potentially be used for the control of olive anthracnose is endophytic fungi.…”

“…Additionally, endophytic fungi are known to produce degradative enzymes (e.g., chitinases, proteases, and glucanases) that have the ability to break down the cell walls of pathogens [ 22 ]. All the aforementioned mechanisms can potentially work cooperatively [ 13 ]. The genus Trichoderma is one of the most studied genera [ 20 ] and also one of the most promising genera in terms of controlling anthracnose caused by species belonging to Colletotrichum , as concluded from in vivo experiments in various crops and different species of the genus Colletotrichum [ 13 ].…”

An alternative approach to disease management involves the application of epiphytic and endophytic bacteria, which compete with the pathogens of the plant for resources and, thus, reduce the severity of the disease [ 23 ].…”

Olive anthracnose is the most important fungal disease of the olive fruit worldwide, with the fungus Colletotrichum acutatum as the main cause of the disease in Greece. A total of 11 commercial biological plant protection products (bioPPPs) (Amylo-X®, Botector®, FytoSave®, LBG 01F34®, Mevalone®, Polyversum®, Remedier®, Serenade® ASO, Sonata®, Trianum-P®, Vacciplant®), with various modes of action against the fungus C. acutatum, were evaluated by bioassays using detached fruits of two important olive Greek varieties, cv. Koroneiki and cv. Kalamon. Subsequently, the most effective bioPPPs were evaluated for their ability to induce plant defense mechanisms, by determining the expression levels of ten Olea europaea defense genes (Pal, CuaO, Aldh1, Bglu, Mpol, Lox, Phely, CHI-2, PR-10, PR-5). Remedier®, Trianum-P®, Serenade® ASO, Sonata®, and Mevalone® were the most effective in reducing disease severity, and/or inhibiting the conidia production by the fungus at high rates. Post bioPPPs application, high expression levels of several olive plant defense genes were observed. This study provides insights into commercial bioPPPs’ effectiveness in controlling olive anthracnose, as well as biocontrol-agents-mediated modulation of olive defense mechanisms.
