“…Pleurostoma richardsiae is known for its pathogenicity and deterioration of the trunk wood of infected trees (Chauiyakh et al, 2022). This fungus causes severe damage to olive trees, leaf browning and leaf drop and wilting of apical shoots, dieback of twigs and branches.…”

“…Finally, these tubes are sterilised for 20 min at 121°C, cooled to 45°C, and poured into Petri dishes to obtain the following final concentrations: 1/100, 1/250, 1/500, 1/1000, 1/2000, 1/3000, and 1/5000. Controls containing the culture medium plus the 0.2% Agar-Agar solution were also prepared (Remmal et al, 1993; SATRANI et al, 2001; Chauiyakh 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.

The valorization of aromatic and medicinal plants is a vital research axis in the field of valorization and optimization of natural resources. Cedar is one of the most sought-after plants in the world due to the quality of its wood and its richness in bioactive molecules that can be used in the pharmaceutical, cosmetic, and perfumery industries. Using keywords such as: Cedrusatlantica Manetti, Cedrusbrevifolia Henry, Cedrus deodara London,Cedruslibani London and Cedrusbrevifolia Henry, articles were collected from international scientific databases. The analysis of the abstracts of these articles by computer tools such as Zotero, Excel, and Nvivo allowed us to conclude that the chemical composition of cedar varies from one species to another and from one part of the plant to another and according to the harvesting environment. However, it is generally characterized by the dominance of terpenes. The latter is known to have antimicrobial properties, which explains the effectiveness of the oils and extracts of this plant against fungi and bacteria such as helicobacter pylori, Gram-positive and Gram-negative bacteria, and important anticancer power.

In this work, new ideas in the realm of picture identification and classification are developed and implemented on hardware. This entails putting new algorithms into practice, whether for color, texture, or shape identification for AI (Artificial Intelligence) and picture recognition applications. We concentrate on identifying edible mushrooms in the harvesting and food manufacturing processes. Our proposal for an embedded system based on a Raspberry-Pi4 type microcomputer employing a combination of hardware and software components has helped with the recognition and classification of items in the image. Our object recognition system is built on a novel neighborhood topology and a cutting-edge kernel function that enables the effective embedding of image processing-related characteristics. We tested the suggested CNN-based object recognition system using a variety of challenging settings, including diverse fungus species, uncontrolled environments, and varying backdrop and illumination conditions. The outcomes were superior to various state-of-the-art outcomes. On the other hand, our contribution relating to the dynamic mode integrates a CNN network to accurately encode the temporal information with an attention mask allowing us to focus on the characteristics of an edible mushroom according to the state of the art, and guarantee the robustness of the recognition. We implemented our algorithm on a Raspberry Pi400-based embedded system connected to a CMOS camera-type image sensor plus an HMI human-machine interface for the instantaneous display of results for the rapid classification of edible and inedible mushrooms.
