“…Treatments with a pomegranate peel extract (PGE) few days before full boom significantly prevented latent infections over the summer period and reduced the premature defoliation of plants ( Pangallo et al., 2022 ). Promising results were also obtained with aqueous leaf extracts of Ambrosia artimisiifolia ( Kleef and Salman, 2021 ).…”

Olive leaf spot caused by Venturia oleaginea: An updated review

et al. 2023

Olive leaf spot (OLS) caused by Venturia oleaginea is widespread in all olive-growing areas and continents, where can cause severe yield losses. The disease is often underestimated for the difficulty to reveal early leaf symptoms and for the pathogen-induced phylloptosis, which creates the illusion of healthy and restored plants. The present review provide updated information on taxonomy, pathogen life style and cycle, epidemiology, diagnosis, and control. Application of copper-based fungicides is the main method to control OLS. However, the regulation 2009/1107 of the European Commission include these fungicides in the list of substances candidates for substitution. It is therefore urgent to find alternative control strategies especially for organic agriculture. Among new approaches/strategies for controlling OLS, promising results have been obtained using nanotechnology, endophytic microbes, and biostimulants.

“…Our findings show a substantial influence of weather condition on cultivar response to OLS. Previous investigations reported similar results on the effect of climatic conditions on the susceptibility of olive cultivars [20,29,38,39]. In fact, Obanor et al [40] and Al-Khatib et al [41] have reported that the variation in susceptibility of olive cultivars under field conditions is due to the effect of environmental conditions such as temperature, relative humidity and light.…”

Olive leaf spot (OLS), also called olive scab and peacock eye, caused by Fusicladium oleagineum, is a major disease that causes significant damage to olive trees. However, we still lack information about how cultivar and environmental factors influence disease development. In this study, evaluation of the incidence and severity on twenty olive cultivars (Olea europaea L.), maintained in an ex situ collection in Morocco, was carried out monthly during the period from March to July 2021. Biochemical parameters were also evaluated for each cultivar including leaf chlorophyll, polyphenols and flavonoid contents. Results revealed that the OLS incidence was highly correlated with severity (r = 0.94) and found to be related to climatic conditions and cultivars. The studied cultivars were classified into four major groups, i.e., susceptible, moderately susceptible, moderately resistant and resistant. Finally, our investigations revealed a partial relationship between resistance to the OLS disease and phenolic and flavonoid leaf contents, supporting the assumption of the potential involvement of such components in cultivar resistance to the disease. Overall, our work highlights the importance of characterizing olive cultivar resistance to OLS in driving the choice of the best varieties for an effective control of the disease in specific warming regions such as Morocco.
