Antifungal activity of epecific plant essential oils against fusarium graminearum
Fusarium graminearum (telemorph Gibberella zeae) is a major phytopathogen causing diseases in cereals with great economic impacts as wheat (Triticum aestivum L. barley (Hordeum vulgare L. corn (Zea mays L. and rice (Oryza sativa L. F. graminearum is a taxonomical member from the division Ascomycota, of the class Sordariomycetidae, the order Hypocreales. It is a hemibiotrophic fungus with asexual and sexual stages. The natural habitat for this species is soil, and the 24 32 oC is the optimal temperature range for F. graminearum [1,2] This species, which was reported to be common in humidity regions in the past years, has now been spreading gradually due to global climate changes and has also been isolated from regions with different climatic characteristics. F. graminearum has been reported to be a major pathogen of head blight and crown rot of wheat, barley and maize (Figure 1) worldwide [3] F. graminearum infections lead to serious economic losses and mycotoxin contaminations in cereal crops. The decrease in quality and quantity of cereals Summary

Composition of Essential Oils (EOs) and their Antifungal Activity against the B. cinerea
Postharvest life of perishable goods undergoes heavy losses during the transport and storage due to the various biotic stresses. High moisture content, nutrients profile and pH makes them susceptible to the attack by microorganisms. Fruits having low pH are basically attacked by fungi and also contaminated by mycotoxins (Moss, 2002) Botrytis cinerea has been identified as remarkable post harvest pathogens in fresh fruits and vegetables (Zhang et al. 2014) It poses big challenge during storage, shipment and marketing because of its different modes of infection and its ability to develop under different conditions prevailing. The synthetic fungicides are basic means of managing these fungal incidences (Narayansamy, 2006) But they have recently come under scanner for posing a potential risk (Tripathi et al. 2008) Use of these chemicals has contaminated the commodities by fungicidal residues which have increased the public concern and also continuous use of fungicides has increased resistance in the pathogen populations (Tripathi and Dubey, 2004) The indiscriminate and excessive use of synthetic fungicides has been a prime cause for the development of resistant fungal pathogen populations, resulting in the use of even greater quantities of antifungal compounds in agriculture and the appearance of increased levels of toxic residues in food International Journal of Current Microbiology and Applied Sciences ISSN: 2319 7706 Volume 9 Number 10 (2020) Journal homepage: http:/www.ijcmas.com

In vitro and in silico evaluation of antifungal activity of cassia (Cinnamomum cassia) and holy basil (Ocimum tenuiflorum) essential oils for the control of anthracnose and crown rot postharvest diseases of banana fruits
Anthracnose and crown rot postharvest diseases of banana fruit are responsible for major postharvest losses of the fruit. For natural control of these diseases, in vitro antifungal activity of cassia and holy basil essential oils was evaluated by disc volatilization method. Cassia essential oil at 6 mL per plate exhibited 100% growth inhibition of both the causative fungal pathogens, namely Colletotrichum musae and Lasiodiplodia theobromae Holy basil essential oil was capable of completely inhibiting the growth of L. theobromae at 6 mL per plate, whereas it could inhibit C. musae up to 96% at 10 mL per plate. Molecular docking and conceptual DFT studies have been performed to ascertain the components of essential oils responsible for antifungal activity based on their binding affinities to chitin synthase protein and chemical behaviour. Components, such as eugenol, cinnamyl acetate, caryophyllene, humulene and trans calamenene, may most likely be responsible for high activity of the tested essential oils as per the in silico results.

Chemical composition and antifungal activity of essential oils and their combinations against Botrytis cinerea in strawberries
Strawberry has a short postharvest shelf life, mainly because of the gray mold caused by Botrytis cinerea The chemical composition and antifungal activities of essential oils from Mentha piperita, Cymbopogon martinii Cinnamomum camphora Mentha spicata and their binary mixtures against B. cinerea were evaluated by different in vitro methods, and also in vivo in vapor phase on inoculated strawberries. The major components present in M. piperita essential oil were menthol (45.37% menthone (20.13% isomenthone (16.94% menthyl acetate (3.81% pulegone (1.89% a terpinene (1.88% isopulegol (1.83% neoisomenthol (1.19% and a terpineol (1.08% in C. martinii essential oil were geraniol (83.82% geranyl acetate (7.49% linalool (2.48% and caryophyllene (1.33% in C. camphora essential oil were linalool (98.39% and M. spicata essential oil were carvone (61.71% limonene (20.22% 1,8 cineole (5% sabinene (2.28% cis dihydrocarvone (1.63% and a thujene (1.4% The highest antifungal activity in vitro was presented by M. spicata and C. martinii essential oils by the direct contact, vapor contact, spore germination, and micro well dilution methods. In vivo, strawberries treated with the vapor of M. spicata and C. martinii essential oils showed a reduction in disease incidence and severity. At a 10% concentration, M. spicata and C. martinii showed a reduction of 100% and 83% in the disease incidence, respectively. Thus, the M. spicata and C. martinii essential oils may be potential alternatives for the control of B. cinerea in postharvest fresh strawberries.

Nanoencapsulated Essential Oils with Enhanced Antifungal Activity for Potential Application on Agri Food, Material and Environmental Fields
Nanotechnology is a new frontier of this century that finds applications in various fields of science with important effects on our life and on the environment. Nanoencapsulation of bioactive compounds is a promising topic of nanotechnology. The excessive use of synthetic compounds with antifungal activity has led to the selection of resistant fungal species. In this context, the use of plant essential oils (EOs) with antifungal activity encapsulated in ecofriendly nanosystems could be a new and winning strategy to overcome the problem. We prepared nanoencapsules containing the essential oils of Origanum vulgare (OV) and Thymus capitatus (TC) by the nanoprecipitation method. The colloidal suspensions were characterized for size, polydispersity index (PDI) zeta potential, efficiency of encapsulation (EE) and loading capacity (LC) Finally, the essential oil nanosuspensions were assayed against a panel of fourteen fungal strains belonging to the Ascomycota and Basidiomycota phyla. Our results show that the nanosystems containing thyme and oregano essential oils were active against various fungal strains from natural environments and materials. In particular, the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) values were two to four times lower than the pure essential oils. The aqueous, ecofriendly essential oil nanosuspensions with broad spectrum antifungal activity could be a valid alternative to synthetic products, finding interesting applications in the agri food and environmental fields.
