Over the past few decades, the intentions have been to ensure the hygiene and safety levels of fruit products along with promoting maximum biodegradability. In order to achieve this ambition, researchers are still trying to screen natural products with strong antifungal potential from plants. Moreover, it has also been tried to explore new preservation technologies that can replace synthetic fungicides. Compared with synthetic fungicides, natural antifungal substances have attained much attention in recent years [6; 7; 8; 9]. Various essential oils refined from _Melaleuca alterifolia_ have strong inhibitory effects on multiple fungal strains, particularly _P. italicum_ Wehmer and _P. digitatum_ Sacc., and hence can be used as natural preservatives in agricultural and food processing [10]. Previously we have reported that cinnamaldehyde contained in cinnamon has a good antifungal effect against _P. italicum_ and clarifies the method for dynamic detection of the antifungal effect of cinnamaldehyde [11]. In addition, GC-MS and GC-FID techniques successfully separated the essential oils components _viz._ limonene (87.02%), linalyl acetate (53.76%) and linalool (39.74%) from peels, leaves and flowers of _Citrus aurantium_ varamara, neroli oil appeared as the best fungistatic agent, which reduced the _P. digitatum_ sporulation to 25 % at a 50 mg/mL concentration of oil [12]. Carvacrol (5-Isopropyl-2-methylphenol) is the major volatile oil constituent from Labiaceae family plants, such as oregano, mint, and thyme [13]. Carvacrol has many medicinal and edible applications, including antifungal, antimicrobial, anti-inflammatory, insecticideidal, antitumor, and other effects [14]. Carvacrol inhibited the growth of _P. digitatum_ and _P. italicum_ in in vitro and in vivo experiments of lemon [15]. Another study in Morocco, reported that _Thymus leptobotrys_ and _T. riatarum_ have carvacrol contents of 76.94% and 32.24%, respectively, and the former species has the highest bioactivity among the tested plant species in that study. In addition, the study reported a complete inhibition of germination of the spore of _P. digitatum_ and _P. italicum_ at 500 \(\upmu\)L/L [16]. The results of the antimicrobial activity assay showed that carvacrol, cinnamaldehyde, and _trans_-cinamaldehyde significantly reduced the growth of _P. digitatum_; particularly, the carviniol appeared as the most effective remedy to control _P. digitatum_[17].
