Olive anthracnose is the most important fungal disease of the olive fruit worldwide, with the fungus 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 , were evaluated by bioassays using detached fruits of two important olive Greek varieties, . Koroneiki and . Kalamon. Subsequently, the most effective bioPPPs were evaluated for their ability to induce plant defense mechanisms, by determining the expression levels of ten defense genes (, , , , , , , , , ). 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.

Article Synopsis
- Anthracnose is the most significant disease affecting olive crops, primarily caused by different species of the Colletotrichum fungus in Spain and Portugal, with C. godetiae and C. nymphaeae being the main culprits.
- The research evaluated the resistance of various olive cultivars, particularly comparing the 'Picual' (resistant) and 'Arbequina' (moderately susceptible) varieties, finding that some offspring hybrids showed improved resistance to C. godetiae.
- Despite the interactions observed between the olive genotypes and Colletotrichum species, traditional and new cultivars generally fell into susceptible or moderately susceptible categories, indicating a complex resistance mechanism and varied responses between fruit and leaf susceptibilities

Olive anthracnose induced by different Colletotrichum species causes dramatic losses of fruit yield and oil quality. The increasing incidence of Colletotrichum fioriniae (Colletotrichum acutatum species complex) as causal agent of olive anthracnose in Italy, is endorsing new studies on its biology, ecology, and environmental factors such as temperature. Five isolates from different sampling sites in Lazio region (Central Italy) were studied under controlled laboratory conditions aiming to better understand the differences of thermal development among the isolates and to lay the foundations of a future mathematical model able to describe the key aspects of the pathogen's life cycle.

Olive anthracnose, caused by fungi, and the olive fruit fly are, respectively, the most important fungal disease and pest affecting olive fruits worldwide, leading to detrimental effects on the yield and quality of fruits and olive oil. This study focuses on the content of hydroxytyrosol (HYT) and its derivatives (the "olive oil polyphenols" health claim) in olive oils extracted from fruits of 'Galega Vulgar' and 'Cobrançosa' cultivars, naturally affected by olive anthracnose and olive fly. The olives, with different damage levels, were harvested from organic rainfed orchards, located in the center of Portugal, at four harvest times over three years.
