“…This disease is characterised by dieback of twigs and branches, necrosis and darkening of bark and wood tissues, gummosis, and canker lesions of Pistacia vera L. (Heidarian et al 2018; Ozan et al 2022). The genus Alternaria is renowned for its pathogenicity (Lakshmi Prasad et al 2020; Kumar et al 2022). Alternaria tenuissima is a plant pathogenic fungus (Patriarca 2016; Kumar et al 2021), it causes the Alternaria rot of potato tubers, characterised by potato degradation and yield reduction (Leng et al 2022).…”

In Morroco, Cedarwood lignivorous fungi cause significant damage to cedar groves. The losses have been estimated to be more than 30% due to these fungi. This latter brings about two primary diseases known as M'jej and Saboune. The study tries to show the molecular identification of the lignivorous fungi of the Atlas cedar in the cedar groves of Tazekka and Azrou and their biological control by the essential oils extracted from both the healthy and infected cedarwood. Therefore, this molecular research has identified three phytopathogenic fungi:(Paecilomyces maximus, Pleurostoma richardsiae, and Alternaria tenuissima). The data analysed in this study has also confirmed that the oil extracted from Saboune-infected wood showed a noticeable fungistatic effect against these fungi, with a MIC reaching 1/500, followed by the EO extracted from M'jej-infected wood. However, the healthy cedarwood gave an EO without antifungal activity. A mixture of these three oils gave significant antifungal results.
