“…Diseases severity of leaf spot of faba bean was recorded and calculated using the arbitrary scale of 0 to 9. Where 0, 1, 2, 3, 4, 5, 6, 7 and 8 represent no visible leaf infection (0) or diseases covering less than 10%, 20%, 30%, 40%, 50%, 60%, 70% and 80 % of the foliar tissue, respectively; (9) represents disease covering more than 80 of the foliar tissue (EL-Hendawy et al, 2010). Disease severity percentage calculated using the following formula:…”

Faba bean (Vicia fabae) is considered the most important legume crop in Egypt. Eighty fungal isolates were isolated from faba bean leaves cultivated in different localities in Assiut and Sohag governorates. All isolates were identified using morphological characteristics of mycelia and spores' features. These isolates were identified by molecular methods using ITS-rDNA sequencing (ITS1 and ITS4). A resulted based on ITS sequences the fungal samples were Alternaria angustiovoidea (OM432027), Curvularia lunata (OM432028) and Fusarium solani (OM432026). Pathogenicity tests were performed in a greenhouse on faba bean cultivar 843. Different degrees of leaf spot disease symptoms were produced by each tested isolate. A. angustiovoidea C. lunata and F. solani produced the highest disease severity percentage 62.33, 62.66 and 50.23%, respectively. Evaluation of four cultivars reaction to leaf spot disease showed that, Giza 843 was the most susceptible cultivar followed by Giza 125 while, the most tolerant cultivar was Giza 2 followed by Giza 667.

“…Compared with traditional chemical fungicides, the use of plant immune elicitors is a more environmentally friendly and sustainable plant protection strategy. It enhances the plant’s resistance to pathogens and other stress factors by stimulating the plant’s own defense system, thereby increasing crop yield and economic benefits [ 9 , 10 ]. Several studies have confirmed that many synthetic and natural chemicals can act as elicitors, such as calcium chloride (CaCl 2 ) [ 11 , 12 ], benzothiadiazole (BTH) [ 13 , 14 ], salicylic acid (SA) [ 15 , 16 ], methyl jasmonate (MEJA) [ 17 , 18 ], β-aminobutyric acid (BABA) [ 19 , 20 ], chitosan [ 21 , 22 ], and silicates [ 23 , 24 ].…”

Background Peanut (Arachis hypogaea), a vital oil and food crop globally, is susceptible to web blotch which is a significant foliar disease caused by Phoma arachidicola Marasas Pauer&Boerema leading to substantial yield losses in peanut production. Calcium treatment has been found to enhance plant resistance against pathogens. Results This study investigates the impact of exogenous calcium on peanut resistance to web blotch and explores its mechanisms. Greenhouse experiments revealed that exogenous calcium treatment effectively enhanced resistance to peanut web blotch. Specifically, amino acid calcium and sugar alcohol calcium solutions demonstrated the best induced resistance effects, achieving reduction rates of 61.54% and 60% in Baisha1016, and 53.94% and 50% in Luhua11, respectively. All exogenous calcium treatments reduced malondialdehyde (MDA) and relative electrical conductivity (REC) levels in peanut leaves, mitigating pathogen-induced cell membrane damage. Exogenous calcium supplementation led to elevated hydrogen peroxide (H2O2) content and superoxide anion (O2∙-) production in peanut leaves, facilitating the accumulation of reactive oxygen species (ROS) crucial for plant defense responses. Amino acid calcium and sugar alcohol calcium treatments significantly boosted activities of peroxidase (POD), superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) in peanut leaves. Activation of these antioxidant enzymes effectively scavenged excess ROS, maintaining ROS balance and mitigating cellular damage. Conclusions In summary, exogenous calcium treatment triggered ROS production, which was subsequently eliminated by the activation of antioxidant enzymes, thereby reducing cell membrane damage and inducing defense responses against peanut web blotch.
