Abstract
Plant diseases represent one of the major problems causing yield loss of tomato crops, especially root rot and seedling damping-off diseases caused by some phytopathogenic fungi like Fusarium solani (Fs), F. oxysporum (Fo), and Macrophomina phaseolina (Mp) frequently detected in tomato either alone or in combination infection. The objective of the present study is to assess the antifungal activity of Origanum majorana extracts against the phytopathogenic fungi, Fs, Fo, and Mp, thereby avoiding controlling the disease with chemical fungicides. In this context, the acetonic extracts of O. majorana exhibited the highest antifungal activity against the tested phytopathogens. However, F. solani exhibited high resistance to Ridomil fungicide at the tested concentrations. A chemical analysis of the O. majorana acetonic extract was conducted to determine the main phytoactive constituents exhibiting fungicidal activity. In this regard, gas chromatography and mass spectrometry confirmed that 4-terpineol was the main phytoactive compound followed by γ-terpinolene exhibiting relative percentages of 24.36 and 8.26%, respectively. These results proved that the marjoram extract may contribute to the development of an alternative and natural fungicide to protect tomato crops from damping off and root rot diseases, avoiding the usage of chemical fungicides.
1 Introduction
Because of the widespread consumption of tomatoes as well as their nutritional and economic importance to farmers, tomatoes are regarded as an essential tropical crop [1]. Fusarium solani, F. oxysporum, and Macrophomina phaseolina are responsible for tomato seedling damping-off disease resulting in huge economic loss and poor quality of yield [2]. Seedling damping-off disease can be controlled by the application of chemical fungicides, the use of pathogen-resistant varieties, and crop rotation [3]. Although chemical fungicides have proven to be effective in preventing the spread of fungal diseases, their repeated use has led to sustained residual toxicity in tomatoes, environmental pollution, disturbing the soil’s biological ecology by killing the useful microflora and causing immense fungicide resistance development [4,5]. Recently, studies have been conducted on the development of biocontrol agents that could be effective and safer for the environment [6]. Within this context, the application of plant extracts as biological controls of tomato damping-off diseases was reviewed [7]. These plant extracts are recognized as safe for the environment, are natural sources of antimicrobials that are easily decomposed by soil microflora, and do not cause any health or environmental hazards [8,9,10,11,12,13,14,15,16]. Origanum majorana extracts are investigated as natural sources of bioactive agents that are environmentally safe, and they do not pose protracted health hazards at any concentration [17]. O. majorana extracts have been investigated to control plant diseases caused by bacterial and fungal plant pathogens [18]. There are numerous studies on pathogens that have been effectively controlled by the use of marjoram extracts such as Sclerotinia sclerotiorum [19], Verticillium dahliae, and Penicillium aurantiogriseum [20], Botrytis cinerea which cause gray mold disease in many plants [21], Aspergillus flavus, A. fumigatus, Microsporum gypseum, Cladosporium herbarium, Candida albicans, Cryptococcus neoformans, Trichophyton mentagrophytes [22], Candida albicans [17,23], Alternaria alternata, Bipolaris oryzae, Fusarium graminearum, Fusarium equiseti, and Fusarium verticillioides [24]. Although the number of bio-control agents is developing, they still represent only a tiny proportion of applicable biocides. Consequently, there is a crucial need to find alternative approaches for controlling damping-off and root rot diseases in tomatoes. However, the use of O. majorana extracts as biocontrol agents against tomato phytopathogenic fungi has received far less attention [25]. Therefore, the objectives of the present study were planned to evaluate the antifungal activity of Origanum extracts against some phytopathogenic fungi (Fusarium oxysporum (Fo), F. solani (Fs), and M. phaseolina (Mp)) causing tomato damping-off disease and to compare efficacy of Origanum extracts as biocontrol agent with that of reference fungicide (Ridomil) in prevention of tomato phytopathogenic fungi in vitro.
2 Materials and methods
2.1 Preparation of O. majorana extracts
Marjoram was purchased from Riyadh markets, Saudi Arabia. The plant (O. majorana) was identified and deposited with voucher number KSU-16653 by the herbarium of the Botany Department, College of Science, King Saud University. The active phytochemicals of Marjoram were extracted using four different solvents (ethanol, methanol, acetone, and distilled water) with corresponding polarity indexes of 4.3, 5.1, 5.1, and 10.2, respectively. A difference in the polarity of the used solvents allows the extraction of all active phytochemicals [26]. Disinfection of marjoram was performed using 0.5% sodium hypochloride (NaOCl) followed by washing of the plant three successive times with distilled water, and finally, the plant was left in the shade to dry. Maceration of the plant was done to attain a homogenized fine powder. Plant extracts were prepared by soaking 50 g of plant powder in four solvents (10 ml of solvent/g of plant powder) with stirring for 48 h, filtered through double layers of muslin, and filtered again through Whatman filter paper No. (41) to remove plant debris. and finally centrifuged at 9,000 rpm for 10 min to obtain a clear filtrate. The supernatants of all extracts were evaporated using a rotatory evaporator to concentrate the marjoram extracts and then refrigerated at 4°C until used.
2.2 Fungal cultures
Fungal cultures of F. oxysporum ATCC-52422, Fusarium solani ATTC-11712, and M. phaseolina ATCC-64334 were provided from the culture collection of the Plant Pathology Lab. at Botany and Microbiology Department, King Saudi University, Riyadh, K.S.A. The cultures were renewed on potato dextrose agar (PDA) plates, preserved in slants, and stored in a fridge at 5°C until used.
2.3 Screening of antifungal activity of marjoram extracts
Antifungal activity was evaluated on tomato phytopathogenic fungi using the food poisoning technique (Mostafa et al., 2013). Sticky plant extracts were re-dissolved in (5 ml) the corresponding solvent, sterilized with a Millipore filter (0.22 µm pores), and mixed with sterile PDA medium to obtain a final concentration of 1.0 mg ml−1 of the marjoram extract and then poured in sterile Petri dishes (90 mm diameter). For control, 5 ml of Millipore-sterilized solvents was added to (PDA) plates. Discs of 7 mm diameter of phytopathogenic fungi were cut from the periphery of 6 days actively growing cultures and placed over the center of Petri dishes of treatment and control sets and then incubated at 25°C ± 2°C for 7 days. The fungal colony diameter of treatments and control sets were measured using Vernier calipers, and the inhibition of mycelial growth was computed using the following formula: Inhibition of fungal mycelial growth (%) = (DC − DT)/DC × 100 (where DC and DT are the fungal colony diameters (mm) in control and treatment).
2.4 Efficiency of standard fungicide (Ridomil Gold) against tomato phytopathogenic fungi
The antifungal efficacy of Mefenoxam (Metalaxyl-M) with trade name (Ridomil Gold SL, 48%) was evaluated using a food poisoning technique. Different concentrations of Mefenoxam (active ingredient) (0.0, 0.125, 0.25, 0.5, 1.0, and 2.0 ppm) were prepared by mixing a measured volume of fungicide with a known volume of sterile (PDA). Fungal plugs of phytopathogenic fungi (7 mm in diameter) were obtained and placed at the center of Petri dishes containing PDA medium, supplemented with various concentrations of fungicide. The plates were incubated at 25°C ± 2°C, and the radial growth of the phytopathogenic fungi, on both control and treated plates, was estimated using Vernier calipers, and the growth inhibition percentage was computed.
2.5 Fungicidal bioassay of marjoram extracts
The marjoram (O. majorana) extract was manipulated to determine its minimal inhibitory concentration (MIC) and minimal fungicidal concentrations (MFCs) to evaluate its efficiency in controlling tomato phytopathogenic fungi compared with standard fungicide (Ridomil Gold SL, 48%).
2.5.1 Detection of MICs of O. majorana
The MIC values were determined as the minimal concentration at which minimal growth was observed compared to the control. MIC was evaluated for the acetonic extract of O. majorana as it demonstrated the highest antifungal efficiency. Different concentrations of the acetonic marjoram extract (0.0, 0.5, 1.0, 2.0, and 4.0 mg/ml) were prepared separately by dissolving their requisite amount in a 10 ml of acetone, sterilized through a Millipore filter, and mixed with the PDA medium to obtain their final concentrations. Fungal discs of pathogenic fungi (7 mm in diameter) were placed at the center of Petri dishes containing PDA medium of various marjoram extract concentrations. The plates were incubated at 25°C ± 2°C, and the fungal growth was measured by Vernier calipers after 6 days. The antimycotic efficacy of the marjoram extract was compared with the fungicidal potency of the reference fungicide with three replications. The fungicidal bioactivity of the marjoram extract was computed and MIC was detected.
2.5.2 Detection of MFC
The MFCs of the acetonic marjoram extract were achieved by picking agar discs from plates showing no visible fungal growth, inoculating on sterile PDA plates, and then incubating at 25°C for 7 days. After incubation, plates showing complete inhibition of fungal growth were recorded as the MFC.
2.6 Ultracellular effect of the acetonic marjoram extract on the fungal cells of phytopathogens using SEM
Mycelial strips of F. solani were selected to demonstrate the effect of the acetonic marjoram extract on the fungal cell morphology. Hyphal strips were obtained from marjoram-treated plates grown on PDA of concentration 1 mg/ml and fixed in 2.5% glutaraldehyde/sodium phosphate buffer (0.13 M, pH 7.2) overnight. The specimens were washed three times with buffer and then post-fixed in osmium tetraoxide for 2 h, washed again with buffer, and dehydrated using increasing ethanol levels (30–100%) for 15 min at each step. The specimens were dried at the critical point and coated with carbon to be examined using a scanning electron microscope (JEOL JSM-6380 LA) operating at 20 kV.
2.7 Gas chromatography and mass spectrometry (GC-MS) analysis of the acetonic marjoram extract
Acetonic extract of marjoram (O. majorana) was analyzed using a GC-MS Agilent system (model GC-7890B-MS-5975, Agilent Technologies, USA). The analysis was carried out using an HP5MS capillary column (30 m × 0.25 mm; 0.25 μm film thickness). The operating conditions were as follows: injection and detector temperature, 250 and 300°C, respectively; carrier gas, helium with a flow rate of 1.0 ml/min. The initial oven temperature program was 50–300°C, increased at a rate of 5°C/min, then by 9°C/min to 250°C. Mass spectrometer conditions were as follows: ionization potential, 70 eV; mass range from m/z, 50–650 amu; and electron multiplier energy, 2,000 V. The total run time was 60 min and the bioactive compounds of the Majoram extract were identified by comparison of their relative retention times and the mass spectra with those authentic reference compounds shown in the literature and by computer matching of their MS spectra with Wiley and Nist, 8 mass spectral library [26].
2.8 Statistical analysis
All experiments were performed in three replicates for each treatment. The data were reported as mean ± SE (standard error) and analyzed statistically using a one-way analysis of variance. Differences among the mean values were determined for significance at P ≤ 0.05 (by SPSS, 16.1 Chicago, USA).
3 Results
3.1 Screening of antifungal activity of marjoram extracts
The antifungal activity of marjoram (O. majorana) extracts was screened and evaluated against some tomato phytopathogenic fungi (F. oxysporum, F. solani, and M. phaseolina) in vitro (Table 1). The acetonic extract of marjoram at 1 mg/ml was highly effective in suppressing the mycelial growth of F. oxysporum, F. solani, and M. phaseolina to 78.13, 72.92, and 83.33% compared to the non-treated control. The marjoram ethanolic extract was moderately effective in reducing the mycelial growth of all concerned tomato phytopathogens to 55.17, 60.42, and 56.25% respectively, while methanolic and aqueous extracts of marjoram were less efficient in controlling the studied phytopathogenic fungi.

3.2 Efficiency of standard fungicide (Ridomil Gold) against tomato phytopathogenic fungi
M. phaseolina was the most sensitive fungal isolate to Ridomil-Gold fungicide at a concentration of 0.5 ppm, F. oxysporum was moderately affected, whereas F. solani was resistant to ridomil as shown in Table 2. At a concentration of 1.0 ppm, ridomil prevented the mycelial growth of M. phaseolina completely and inhibited the F. oxysprum and F. solani by 67.25 and 53.5%, respectively. Moreover, the fungicidal activity of ridomil against the tomato phytopathogens was obvious and completely suppressed the fungal growth of M. phaseolina and F. oxysporum and inhibited the growth of F. solani to 80.38% at a concentration of 2.00 ppm, respectively. Ridomil-Gold was strongly effective against M. phaseolina with an MIC of 0.125 ppm and an MFC of 1.0 ppm while it showed fungistatic activity against F. oxysporum with an MIC of 1.0 and an MFC of 2 ppm.

3.3 Fungicidal bioassay of marjoram extracts
The acetonic extract of O. majorana was highly efficient and showed fungicidal and fungistatic activities against the concerned F. oxysporum, F. solani, and M. phaseolina with an MIC of 0.5 mg/ml and an MFC of 2 mg/ml, respectively (Table 3). The concentration effect of the acetonic marjoram extract (O. majorana) on the mycelial growth of tomato phytopathogens is shown in Figure 1 and plotted against the mycelial growth of the respective fungi (Figure 2). However, differences in the antifungal activities of the marjoram acetonic extract against tomato phytopathogenic fungi were highly significant at P > 0.05. F. oxysporum and M. phaseolina were significantly susceptible (P ≤ 0.05) to the marjoram acetonic extract, compared with the control, while F. solani was less susceptible. Growth inhibitions of phytopathogenic fungi were increased as the concentrations reached 80.89, 76.13, and 85.63% at 1 mg/ml and completely stifled at 2 mg/ml of the extract (Figure 3).

Finally, the O. majorana acetonic extract had fungistatic and fungicidal activities against all tested fungi with MICs of 0.5 mg/ml, suppressed fungal growth strongly at 1 mg/ml, and showed MFCs of 2 mg/ml for all tested fungi.
3.4 Ultracellular effect of the acetonic marjoram extract on the fungal cells of phytopathogens using SEM
The morphological and ultrastructure characterization of F. solani (which was selected as a model for fungal growth changes) in response to the acetonic marjoram extract using an SEM revealed dramatic alterations to the morphology and ultrastructure of the test pathogen in comparison to the control. The SEM results of the F. solani (untreated) were characterized by lengthened hyphae, of constant diameter, sub-parallel and with rounded or lightly tapering apex, smooth external surface with the presence of conidia, and the growth was very dense. Meanwhile, most of the formed fungal mycelia appeared to grow parallel and adherent at 800× power (Figure 4a). By contrast, the SEM micrographs of F. solani treated with 1 mg/ml O. majorana extract, clearly showed curly hyphae, varied diameter, irregular branching hyphae (Figure 4b), deformed, wrinkled external surfaces, and incomplete growth of apex (Figure 4c). Also, the presence of chlamydospores, besides the formed conidia, was embedded and overlapped (Figure 4d). Similar damage to morphology and ultrastructure of fungal cells when treated with different plant extracts was reported [27,28].

3.5 GC-MS analysis of the acetonic marjoram extract
The acetonic marjoram extract was chemically analyzed by GC-MS to estimate and identify the chemical constituents of the extract. The compound name, chemical formula, molecular weight, and structure of marjoram constituents are given in Table 4. The analysis revealed the presence of various bioactive phytochemical compounds, mainly terpines and terpines derivatives like 4-terpineol, γ-terpinolene, β-terpineol, α-terpineol, camphene, α-phellandrene, carvacol, 6-methyl-6-hepten-4-Yn-2-Ol, 1,5-hexadiyne, and undecanal, which may be responsible for the growth inhibition of tomato phytopathogenic fungi.

4 Discussion
Chemical fungicides are applied to control damping-off infections in tomato seedlings. Since fungicides are thought to be responsible for a number of carcinogenic and teratogenic attributes as well as residual toxicity, there is considerable debate about the safety aspects of those currently in use. Finding natural and efficient alternatives for chemical fungicides against fungal plant pathogens is of increasing importance as the trend toward eco-friendly organic production methods in agriculture expands [29]. In this context, tomato damping-off diseases can be controlled using plant extracts like the acetonic marjoram extract. To assess the effectiveness of the marjoram extract in preventing tomato phytopathogenic fungi, it was evaluated in vitro at a concentration of 1 mg/ml against F. oxysporium, F. solani, and M. phaseolina.
Assays revealed that the O. majorana extract provided a significant inhibition of mycelial growth of all relevant phytopathogenic fungi and their sensitivity varied extensively. The O. majorana extract was highly effective in suppressing the mycelial growth of M. phaseolina and F. oxysporum and inhibited to 83.33 and 78.13%, while F. solani was less sensitive and its mycelial growth and was inhibited to 72.92% at 1 mg/ml. These results are in accordance with those of Dhaouadi et al. and Raouafi et al. [30,31]. A variation in fungi toxicity of the acetonic marjoram extract against tomato phytopathogenic fungi may be due to variation in the fungal species itself [32,33].
The study of MIC and MFC of the fungi toxicants compared with reference fungicide is necessary to evaluate their efficacy in suppressing mycelial growth of the phytopathogenic fungi. The marjoram extract was strongly active against the tomato phytopathogenic fungi but its MIC and MFC were comparatively higher than that of the reference fungicide. However, Ridomil-Gold SL 48% fungicide was the most effective fungi toxicant suppressing the growth of phytopathogenic fungi than marjoram extracts, as the mycelial growth of the three phytopathogenic fungi was completely inhibited at 2 ppm while a concentration of 2 mg/ml was required for the marjoram extract to attain the same effect.
Antifungal compounds present in the O. majorana extract were analyzed by GC-MS and 23 compounds were identified. Della-Pepa et al. identified terpinen-4-ol and carvacol as the primary bioactive constituents of O. majorana extracts using GC-MS analysis. Furthermore, Della-Pepa et al. observed that these extracts exhibited fungi toxic properties [34].
Hajlaoui et al. stated that the antifungal potency of the marjoram extract can be attributed to the major constituents of monoterpenes or the synergetic effect of these compounds [35]. Kadoglidou et al. showed that the concentration of oxygenated compounds directly affected the antifungal activity [36]. Vagi et al. and Adams and Ahmed reported that terpinen-4-ol was the main active compound for the antifungal activity [37,38]. Eventually, the antimycotic potency of the essential oil depended on the composition and concentration of the marjoram extract [39].
5 Conclusions
The antifungal potency of the O. majorana extract gives a new opportunity to control tomato damping-off diseases that cause damage at the seedling stage, especially in condensed agriculture. The present study showed that the application of marjoram extract as a bioagent was found to be effective in the suppression of some fungi causing tomato damping-off diseases. These results proved that the marjoram extract may contribute to the development of an alternative and natural fungicide to protect tomato crops from damping-off and root rot diseases, avoiding the usage of chemical fungicides.
