“…EOs can represent one of the most promising natural products for fungal inhibition [ 15 , 16 ]. In fact, many kinds of EOs obtained from different plants or herbs exhibited intense antifungal properties [ 4 , 15 , 17 , 18 , 19 ]. EOs, like the other phytochemicals, could attenuate the microbial growth and biofilm development through specific mechanisms [ 10 ].…”

Since ancient times, folk medicine and agro-food science have benefitted from the use of plant derivatives, such as essential oils, to combat different diseases, as well as to preserve food. In Nature, essential oils play a fundamental role in protecting the plant from biotic and abiotic attacks to which it may be subjected. Many researchers have analyzed in detail the modes of action of essential oils and most of their components. The purpose of this brief review is to describe the properties of essential oils, principally as antifungal agents, and their role in blocking cell communication mechanisms, fungal biofilm formation, and mycotoxin production.

“…The different chemical compositions of the essential oils may be the cause of the variation in antifungal activity at the same concentration (Nazzaro et al, 2017). Thus, essential oils are among the significant plantbased substance that have a strong inhibitory effect on the mycelial growth and spore germination of fungal contaminants (Kalemba and Kunicka, 2003;Prakash et al, 2012;Ghalem, 2016;Hu et al, 2019). So, to preserve the quality and extend the shelf life of mushrooms in postharvest conditions, EOs can be used as a good alternative (Ju et al, 2019) to synthetic fungicides (Nuvan, Bavistin DF and Dicholrophus 76 EC, Mancozeb and Carbendazim etc.)…”

Being highly perishable, mushrooms’ quality and shelf life is affected by various factors during postharvest conditions, among which fungal contamination is the main cause. The goal of this study is to identify and manage fungal contaminants present in mushrooms during postharvest conditions. A total of 23 fungi were isolated as contaminants from the samples of Agaricus bisporus collected from three major vegetable markets in Kathmandu city, Nepal. Aspergillus niger, Aspergillus flavus, and Rhizopus stolonifer were found to be the most frequent fungal contaminants. These were treated with various concentrations of essential oils (EOs) of Cinnamomum tamala, Mentha spicata, Zanthoxylum armatum, and Eucalyptus citriodora using poisoned food technique. Significant (p<0.05) inhibition of mycelial growth and spore germination was found in all testedfungi by all EOs. A strong inhibitory action of M. spicata oil was recorded against A. flavus and R. stolonifer while, A. niger was best controlled by C. tamala oil at the concentration of 20 µl/ml. These results suggest that EOs of three tested plants could be a good alternative to control fungal contaminants and extend the shelf life of Agaricus bisporus in postharvest conditions.

“…Bacterial soybean blight is di cult to control. One of the suggested methods is using pathogen-free seeds, or chemical compounds such as copper and antibiotics (Ghalem, 2016). The treatment with streptomycin at 250 ppm has been documented to be effective, but it is not a recommended option due to the potential development of bacterial resistance caused by antibiotics (Gade et al, 2021).…”

Pseudomonas savastanoi is the causal agent of bacterial blight in Glycine max. One of the routes of transmission of this pathogen is through seeds. Therefore, treating seeds with compounds that reduce bacterial proliferation represents an appealing solution to prevent production losses. Currently, studies focus on the search for natural products derived from aromatic plants with antimicrobial properties as effective and environmentally prudent alternatives. This study aims to further investigate the efficacy of oregano and thyme essential oils in treating seeds against this pathogen. In a previous study, greenhouse trials were conducted using thyme oil. In this research, greenhouse trials were performed using oregano essential oil, and field trials were conducted for both oils. In both oils, a non-phytotoxic concentration of 0.89 mg/ml for oregano essential oil and 1.76 mg/ml for thyme essential oil was determined. Both essential oils reduced the incidence and severity of the disease and the number of cells in the seeds, showing that thyme oil has a better effect than oregano under controlled conditions and in the field. The results obtained in this study demonstrate the efficiency of natural products in reducing pathogenic bacteria in seeds, representing a new natural alternative to control these microorganisms.
