“…The inhibitory effect of garlic essential oil against A. parasiticus may be due to sulfur compounds. The essential oil used previously was analyzed by Muy-Rangel et al (2017) and report diallyl disulphide (23.64 %) and diallyl sulphide (20.33 %) in garlic essential oil (Sigma-Aldrich ® , lot MKBB8390V). These compounds of sulfur may interact with sulfhydryl groups of proteins (El-Sayed et al, 2017) in the cell membrane.…”

“…For example, garlic (Allium sativa L.) is one plant used word-wide; it has volatile compounds with a broad antimicrobial spectrum (Benkeblia, 2004;Bayan et al, 2014). The antifungal properties of garlic essential oil have been showed in several studies against A. pasasiticus, A. niger, Penicillium cyclopium, Fusarium oxysporum, Penicillium funiculosum and Alternaria tenuissima (Gowda et al, 2004;Li et al, 2014;Muy-Rangel et al, 2017). In addition, Gowda et al (2004) previously reported that garlic essential oil reduced aflatoxin production in mixed feed.…”

“…Antifungal activity of garlic (Allium sativum L.) essential oil (Sigma-Aldrich ® , lot MKBB8390V; characterized by Muy-Rangel et al, 2017) was determined by the poisoned food technique (Balouiri et al, 2016). Essential oil was dissolved in sterile PDA-Tween ® 80 (1 % v v -1 ) at ≈ 45 °C to obtain different concentrations (10, 100, 500, 1000 and 10,000 ppm).…”

Background: Aspergillus parasiticus is a mold to produce aflatoxins, and growth in maize; the used synthetic fungicides for their inhibition are risk to health and the environment. However, garlic essential oil to have antifungal activity and can be alternative for control A. parasiticus. Objective/hypothesis: Essential garlic oil can inhibit the in vitro growth of A. parasiticus and its aflatoxins. Methodology: The in vitro antifungal activity of garlic (Allium sativum L.) essential oil was evaluated against A. parasiticus (radial growth and spore germination). In addition, the mean inhibitory concentrations (IC50) and minimum inhibitory (MIC) were calculated. Aflatoxins were tested on maize with High-Performance Thin-Layer Chromatography (HPTLC). Results: The mean inhibitory concentration (IC50) and minimum inhibitory (MIC) obtained by Probit analyses with radial growth were 971 and 2875 ppm of garlic essential oil, respectively, in A. parasiticus. These concentrations inhibited spore germination until 24 h. Starting from 100 ppm of garlic essential oil, mycelial inhibition was shown. Evidence of inhibition of aflatoxin production by A. parasiticus in maize was not possible at concentrations of 971 and 2875 ppm garlic essential oil. Implications: The concentrations 971 and 2875 ppm of garlic essential oil inhibited the growth in vitro of A. parasiticus. However, they did not inhibit aflatoxin production by A. parasiticus into maize. Conclusion: Garlic essential oil inhibit the in vitro growth of A. parasiticus on growth radial and germination spores; but not inhibit aflatoxins production on maize to concentrations 971 and 2875 ppm of garlic essential oil.

“…Tween ® 80 was used as a surfactant in this study due to its low irritation, low toxicity, and high stability, and also because it does not have a fungitoxic effect against Alternaria spp. [18] and others when used at concentrations of 1% to 3% (v•v −1 ) [19,20].…”

Alternaria brown spot (ABS) is a disease caused by the fungus A. alternata f. sp. citri, which results in lesions on the fruits, leaves, and branches of several mandarin varieties and their hybrids. Due to the high cost of fungicide application, alternative methods for controlling ABS need to be studied. Therefore, this study aimed to evaluate the use of essential oils (EOs) from different mandarin varieties to mitigate the effects of ABS. The inhibitory effect of different concentrations (1, 2, 4, 8, and 16 μL·mL−1) of the EOs of Fremont IAC 543 mandarin, IAC 2019Maria mandarin, Murcott IAC 221 tangor, and Late IAC 855 willowleaf on the in vitro mycelial growth of the fungus A. alternata was evaluated. Additionally, the curative and preventive effects of these EOs on the ABS symptoms in detached leaves of Murcott IAC 221 tangor were also assessed. The EO of IAC 2019 Maria mandarin induced less mycelial growth, and consequently, a greater inhibition of the growth of the fungus A. alternata at a concentration of 16 μL·mL−1. This EO was more effective for control than the other oils tested. In the detached leaf experiment, both the curative and preventive treatments at a concentration of 16 μL·mL−1 showed lower values of disease severity.

“…After the incubation times, the cellophane membranes containing mycelium were removed to calculate the fungal biomass by weight difference, using a convection air oven at 105 • C for 2 h. The dry weight was expressed in mg box −1 [19]. The dried mycelium was triturated with 10 mL of ethyl acetate to extract cinnabarin in a 500 mL Erlenmeyer flask to a final volume of 50 mL.…”

Phaseolus vulgaris is the most legume cultivated in the world; in Mexico, it is considered the second most important crop after corn. The aim of this research was to determine the characteristics of Xanthomonas campestris strain “Xcf1-APJR” isolated from the leaves of bean crops, and determine the antimicrobial activity of cinnabarin on this strain. Bacterial cultures were obtained from leaves with necrotic leaf spot symptoms of bean plant variety “Flor de Mayo M38” in Puebla, Mexico. The antimicrobial activity of cinnabarin was tested at 7, 14 and 21 days on X. campestris pv. campestris. The Xcf1-APJR strain showed 100% identity with X. campestris pv. campestris as a causal agent of necrotic leaf spot. Treatment with a potato dextrose medium with a dehydrated sugar cane (PDA+C) showed a higher orange pigmentation than the other treatments after 7, 14 and 21 days of incubation and a higher concentration of cinnabarin (54.33 InU/g) with in vitro antimicrobial activity against X. campestris pv. campestris.
