“…Similarly, the combination of treatments T+E+F showed distinct effects on amino acids, with elevated concentrations of phenylalanine (104.3 ± 3.5) and lysine (381.6 ± 13.1). These findings align with research suggesting that the combination of different treatments can elicit synergistic effects on plant metabolism, leading to enhanced resistance against pathogens [30][31][32]. Certain components within essential oil blends can enhance the penetration of other bioactive molecules into the fungal cells.…”

This study explored the impact of essential oil combinations on Botrytis cinerea-infected apples, focusing on how these treatments affect the levels of amino acids, anthocyanins, organic acids, phenolic compounds, and hormones. We discovered significant differences in amino acid concentrations, particularly asparagine, serine, histidine, glycine, and arginine, between control and fungus-treated apples. Preventive measures notably increased anthocyanins like delphinidin-3-glycoside and peonidin-3-glycoside, while combinations such as thymol + fungus balanced anthocyanin profiles effectively. Organic acid and phenolic compound analyses showed that curative strategies generally increased concentrations, with the thymol + cineole + fungus treatment being especially effective. Hormonal analysis highlighted the benefits of preventive measures in raising indole-3-acetic acid and gibberellic acid levels, whereas curative treatments increased abscisic acid and salicylic acid concentrations. The combination of cineole and thymol with fungicide emerged as a potent strategy for enhancing phenolic content. These findings underscore the potential of specific essential oil combinations in improving the biochemical composition of B. cinerea-infected apples, offering new avenues for enhancing fruit quality and sustainability in the agriculture sector.

“…Among these fungi, Rhizoctonia solani and Sclerotium rolfsii, persist as vegetative mycelium and/or sclerotia and cause uncountable numbers of diseases in cultivated plants (Elsharkawy et al, 2022). Important crops threatened by R. solani and S. rolfsii include the tropical creeper golden pothos, Epipremnum aureum (Norman and Ali, 2018). This plant is grown commercially worldwide for ornamental purposes as a garden and houseplant.…”

Fungi, including Rhizoctonia solani and Sclerotium rolfsii, pose a significant threat to agricultural productivity, causing substantial crop yield and quality losses. The excessive use of conventional fungicides raises concerns regarding their environmental impact and human health. This study explores the antifungal potential of thyme and clove oil nanoemulsions as a sustainable alternative. Nanoemulsions were prepared using high-energy ultrasonication and exhibited remarkable stability, with homogenous particle size distributions and low polydispersity index values. In vitro assays demonstrated complete fungal growth inhibition at 3000 ppm for both oils. Pot bioassays revealed significant antifungal activity, with thyme oil nanoemulsion reducing R. solani and S. rolfsii root rot by 75% and 50%, respectively. Clove oil nanoemulsion also effectively suppressed these pathogens by 41.67% and 25%, respectively. Thyme and clove oil nanoemulsions treatments significantly stimulated root growth under fungal challenge. In this regard, plants treated with thyme oil nanoemulsion showed remarkable increases in root length (4.61-fold and 11.18-fold), fresh weight (28.59-fold and 45.62-fold), and dry weight (48.29 and 48.43-fold) when exposed to R. solani and S. rolfsii infection, respectively, compared to untreated control. Clove oil nanoemulsion also significantly enhanced these root attributes, with remarkable increases in length (1.87-fold for R. solani and 4.12-fold for S. rolfsii), fresh weight (11.09fold for R. solani and 21.31-fold for S. rolfsii), and dry weight (25.14-fold for R. solani and 16-fold for S. rolfsii). Molecular modeling studies supported the observed antifungal efficacy. In conclusion, thyme and clove essential oil nanoemulsions are promising candidates that act as natural fungicides for managing root rot diseases.

This study investigated the effects of individual and combination applications of EOCs against Botrytis Cinerea in apple fruits, with a focus on sugar, vitamin, and antioxidant enzyme dynamics. In protective and curative treatments, sucrose content varied between 18.9 and 87.9 g.L-1, with the “CT” group exhibiting significantly higher sucrose levels (87.9 g.L-1). Glucose content ranged from 6.2 g.L-1 (“CT” and “C + F”) to 35.5 g.L-1 (“T + C + E + F”). Fructose content varied significantly, with the “F + T + C + E” treatment showing the highest (11.4 g.L-1) and the “CT” group the lowest (2.5 g.L-1). Rhamnose content in the curative treatment reached 14.9 g.L-1 (“F + T”) and in the protective treatment, the “C + E + F” group had the highest (3.3 g.L-1). Galactose content ranged from 0.1 to 13.0 g.L-1. Xylose content in curative treatment ranged from 12.1 to 13.6 g.L-1, with the combination “F + T” displaying the highest. In preventive treatment, arabinose content ranged from 0.7 to 3.0 g.L-1, with the “T + C + F” group having the highest. In terms of vitamins, the combination “T + F” showed the highest B1 (25.4 mg.100 g-1) and B2 (24.6 mg.100 g-1) content. Vitamin A, B1, and B2 increased in the “F + T” group, and vitamin C increased in the “F + T + C” group (33.4 mg.100 g-1). The quantification of oxidative stress markers and antioxidant enzymes revealed significant reductions in H2O2, MDA, and proline levels in EOC applications. In preventive treatment, the combination “T + C + E + F” exhibited the most effective improvement in SOD activity (556.5 EU mg-1 ), CAT activity increased significantly in the “T + C + F” group (189.3 EU mg-1), and APX activity saw the highest increase in the “T + C + E + F” group (185.6 EU mg-1). Contrastingly, curative treatments showed higher H2O2, MDA, and proline levels. The most significant decrease in H2O2 level occurred in the “T + C + E + F” group (36.7 nmol.g-1), and a significant decrease in MDA level was noted in the same group. Notable changes were observed in the activities of antioxidant enzymes, with the “F + T + C + E” group displaying the highest SOD activity (440.7 EU mg-1), and the “F + T” group showing the highest GST activity (542.0 EU mg-1). This research provided comprehensive insights into the biochemical responses of apple fruits to EOC treatments, offering potential strategies for effective fungal management in agriculture.
