In this study, antiphytopathogenic fungi activities of the leaf and cones essential oils and its constituents from Cunninghamia lanceolata were evaluated in vitro against 6 plant pathogenic fungi. The main compounds responsible for the antiphytopathogenic fungi activities were isolated and identified. The essential oil from the fresh leaves and cones of C. lanceolata was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS, respectively. The leaf oil consisted primarily of ferruginol (10%), τ-cadinol (8.2%), and α-cadinol (6.6%); the cones oil’s main constituents were abietadiene (42.5%), abietatriene (13.1%), and α-pinene (9.6%). Comparing the antiphytopathogenic fungi activities of the oils suggested that leaf oil was the most effective one. Further fractionation of the leaf oil produced ferruginol, τ-cadinol, and α-cadinol. The 3 compounds exhibited very strong antiphytopathogenic fungi activities. For the antiphytopathogenic fungi activities of the leaf oil, the active source compounds were determined to be ferruginol, τ-cadinol, and α-cadinol.

Certain natural products extracted from different parts of medicinal and aromatic plants were examined for their antifungal activity against three plant pathogenic fungi, Fusarium oxysporum, Rhizoctonia solani, and Alternaria solani, and insecticidal activity against mosquito larvae (Culex pipiens). Acetone extract of Tectona grandis showed the highest antifungal activity against R. solani and A. solani with EC50 values of 118 and 294 μg/mL, respectively. The highest larvicidal activity was displayed by the essential oils of Ocimum basilicum and Eucalyptus gomphocephala with LC50 value of 22, and 30 mg/L, respectively. By gas chromatography–mass spectrometry (GC/MS) analysis 3-allylguaiacol (65.8%) and eugenol acetate (46.6%) were the main compounds in Syzygium aromaticum methanolic extract and essential oil, respectively. The main compound in T. grandis acetone extract was cyclohexylpentyl oxalate (8.7%); its water extract contained (E)-4,4-dimethyl-2-pentene (51.1%); E. gomphocephala branch oil contained p-cymene (28.8%); Euphorbia paralias leaf extract contained 1βH-romneine (26.3%); the seed extract contained α-linolenic acid, TMS (15.2%); Punica granatum extract contained furfural (32.1%); and O. basilicum essential oil contained estragole (65.9%). Thus, extracts from the tested plants can be used as natural biofungicides to manage diseases caused by F. oxysporum, R. solani, and A. solani. Additionally, these extracts show potential larvicide activities against mosquito larvae.

Resistance to conventional fungicides causes the poor disease control of agriculture plant essential oils have a great potential as novel fungicide sources for controlling pathogenic fungi. In this study antifungal activity of the essential oil of Cymbopogon distans and Cinnamomum tamala were evaluated in vitro against ten plants pathogenic fungal activity was evaluated with three replicates. The result showed C. distans and C. tamala essential oil with maximum zone of inhibition against Fusarium sp. (12.53 ± 0.97 mm) and P. aurantiogriseum (12.06 ± 0.52 mm) while minimum activity was seen against R. solani (6.83 ± 0.41, 6.16 ± 0.16 mm) zone of inhibition respectively. The highest efficacy was observed for C.distans essential oil where the MIC values 0.625 mg/ ml against A. flavus and Pythium sp. So, plant essential oils have the potential to replace the synthetic fungicides in the management of postharvest diseases of fruits and vegetables.

The present study reports the results of gas chromatographic-mass spectrometric (GC/MS) analyses of the essential oils from the aerial parts of Ballota nigra L. ssp foetida (Lamiaceae) collected at flowering and fruiting times, as well as their in vitro antifungal activity against nine plant pathogenic fungi. Moreover, the essential oils were evaluated for their antifungal activity using the agar dilution method, and also MICs (minimum inhibitory concentrations) and MFCs (minimum fungicidal concentrations) were determined. The major compounds identified in the flowering and fruiting aerial parts oils respectively were β-caryophyllene (22.6% and 21.8%), caryophyllene oxide (18.0% and 20.5%) and germacrene-D (16.5 and 13.1%). The oils showed in vitro antifungal activity against some species of Fusarium, Botrytis cinerea, and Alternaria solani. Our study indicates that the oil of B. nigra ssp foetida could be used as a control agent for plant pathogenic fungi in natural formulations.

Plant Pathogenic Fungi

Essential oils are obtained from non-woody parts of the plants, particularly foliage, stem or hydrodistillation. They are complex mixture of terpenoids and variety of aromatic phenols, oxides, ethers, alcohols, esters, aldehydes and ketones that determine the characteristics aroma and odour of the donor plants. Presence of volatile monoterpenes or essential oils in the plants provides an important defense strategy to the plants, particularly against herbivorous insect pest and plant pathogenic fungi. Fungi cause huge amount of yield losses due to their ability to cause serious devastating diseases to the crops. Minimizing their effect on the crops need to get a promising way of controlling them. Therefore, the use of essential oils could be a good option to tackle the challenge of fungal diseases. Essential oils are natural products that are extracted from plants by different methods. They have been used for a long history of time for different purposes. Fungicides used in disease management are expensive for resource-poor farmers andnegatively correlation with ecosystems. Nowadays there is a huge interest to use them as plant protection product to be alternative for new agro-chemicals with large antimicrobial spectrum properties. As we observed from the antifungal trials in different literature, the essential oils have a great antifungal effect on many plant pathogens and inhibited most of the tested plant pathogens in the laboratory. Thus, essential oils could be a control agent for plant fungal diseases and further investigation is required to use in the field. This review summarized that the importance, antimicrobial activity and management of fungi.

In order to develop natural antistaling agent for Morchella preservation, reduce environmental pollution problems. In this experiment, the fungus pathogenic fungi were isolated and identified, and the antibacterial activity of the pathogen was determined by using 30 plant essential oils. The results showed that the fungal strain YDJ-S was isolated from the naturally occurring Morchella, belonging to the Fusarium proliferatum, which showed obvious pathogenicity. In vitro antibacterial experiments of essential oils show that in 30 kinds of essential oils, five essential oils of Basil, Cinnamon, Litsea cubeba, Clove and Garlic have obvious inhibitory effect on strain YDJ-S, and the inhibition rate is 100% at 1000 μl/L. Basil essential oil has the most obvious inhibitory effect on the minimum inhibitory concentration and minimum bactericidal concentration of strain YDJ-S, the minimum inhibitory concentration is 250 μl/L, and the minimum bactericidal concentration is 1000 μl/L, to lay the theoretical foundation for further research.
