“…The disease index (DI) with a scale from 0 to 5; 0 = no rotting, 1 = 1–10%of the fruit surface, 2 = 11–20%of the fruit surface, 3 = 21–30%of the fruit surface, 4 = 31–50%of the fruit surface, and 5 = more than 50%of the fruit surface 37 . The efficacy of each treatment was rated based on its DSI: EE: Extremely effective (DSI = 0%), HE: Highly effective (DSI = 0.1–5%), E: effective (DSI = 5.1–25%), I: In-effective (DSI = 25.1–50%) and HI: Highly in-effective (DSI = 50.1–100%) 38 .…”

The study investigated the antifungal and phytochemical properties of three forest plants (Eucalyptus globulus, Pistacia lentiscus, and Juniperus phoenicea) against apple diseases caused by Colletotrichum gloeosporioides and Alternaria alternata. The determination of the total polyphenol and flavonoid contents in the three aqueous extracts of studied plants showed that E. globulus exhibited the highest contents than those of P. lentiscus and J. phoenicea. Furthermore, the three studied extracts showed very appreciable antioxidant activity with decreasing order: E. globulus, P. lentiscus, and J. phoenicea. The phytochemical analysis showed different common phenolic acids in the three studied plants namely: quinic acid, gallic acid, chlorogenic acid, and caffeoylquinic acid as well as other flavonoids mainly quercetin and catechin. The results of the current study demonstrated that the fungistatic activity of E. globulus EO (4 and 2 µl/ml) seemed to be the most effective under laboratory conditions with an inhibition zone diameter above 16 mm. However, the poisoned food technique indicated that the aqueous extract (80%) and the essential oil (4 µl/ml) of E. globulus exhibited the highest mycelial growth (> 67%) and spore germination (> 99%) inhibition. Preventive treatments with essential oils (4 µl/ml) and aqueous extracts (80%) applied to apple fruits inoculated with A. alternata and C. gloeosporioides resulted in the lowest lesion diameter (< 6.80 mm) and disease severity index (< 15%) and the most favorable inhibitory growth (> 85.45%) and protective potentials (> 84.92%). The results suggest that E. globulus has a brilliant future in the management of anthracnose and Alternaria rot of apple and provide a basis for further studies on its effects under field conditions.

“…Compounds of essential oils represent an ecofriendly and bio-safe alternative to increase agricultural productivity and to maintain the pathogen population under economic injury level [32]. Singh et al [31] stated that the essential seed oil of Anethum graveolens was found to be highly effective for the management of the growth of Penicillium citrinum, F. graminearum and Aspergillus niger.…”

Recently plant essential oils received increasing attention for plant health and food security in the sustainable agriculture context. Essential oils are promising biological sources since they are cost-effective, biodegradable, and safe for human health and the environment. This review covers the essential extraction characteristic, extraction methods, and conservation needed for the scientist’s and industries’ knowledge. Furthermore, the main biological activities and involvement of essential oils in plant pests and diseases are outlined. Finally, this review concludes the potential commercial application and the future challenges of essential oils as an eco-friendly method in sustainable agriculture.

“…Some strawberry cultivars are less susceptible to grey mould disease than others, but no cultivar is resistant. Due to the lack of strawberry cultivars resistant to B. cinerea and of stable and reliable biological agents, the main means of controlling this disease in commercial strawberry greenhouses and fields has been through the fungicides application to from or before flowering (Evenhuis and Wanten, 2006;Pelayo-Zaldívar et al, 2007 andRhouma et al, 2022).…”

“…Fungicides are presently used to manage B. cinerea with different modes of action such as Hydroxyanilides (Fenhexamid), Phenylpyrroles (Fludioxonil), Succinate Dehydrogenase inhibitors (Boscalid), DeMethylation inhibitors (Tebuconazole), methionine biosynthesis inhibitors (Pyrimethanil) and Dicarboxamides (Iprodione) (Mertely et al, 2000;Creemers et al, 2006 andFeliziani andRomanazzi, 2016). Factors affecting the choice of fungicide are fungicide resistance risk, action mode (protectant, curative or both), efficacy, fungicide treatment interval, cost, presence of other diseases or pests (Dianez et al, 2002;Mertely et al, 2002;Fernandez-Ortuno et al, 2014 andRhouma et al, 2022).…”

Strawberry (Fragaria ananassa Duch.) is an important and valuable fruit because of its unique flavor and economic, nutritional and health benefits. It is one of the most consumed berries worldwide. Grey mould of strawberry fruits, caused by the necrotrophic ascomycete Botrytis cinerea Pers.: Fr., is one of the most important diseases. This airborne pathogen has the ability to kill strawberry cells through the production of reactive oxygen species and toxins causing massive production losses at all development stages and even post-harvest. The intensive production of strawberries has created a favorable environment for this disease. Strawberry grey mould management is typically very input-intensive, in particular with respect to chemical fungicides. As a result, the integrated pest management is required to control strawberry grey mould. A thorough understanding of B. cinerea epidemiology and infection processes is needed to guide future efforts in the development of innovative integrated management practices. This review summarizes the current knowledge of taxonomy and morphology, signs and symptoms, disease development, infection process, and control of B. cinerea using integrated disease management.
