“…In previously reported studies, the sensitivity of B. cinerea from various plant hosts was investigated and antifungal concentrations of extracts and essential oils were determined [ 1 , 10 , 11 , 14 , 15 ]. Mycelial growth of B. cinerea from tomato was inhibited by origanum essential oil at 12.8 µg/mL and lavender and rosemary essential oils at 25.6 µg/mL [ 1 ].…”

“…In another tomato B. cinerea study, the pathogen expressed high sensitivity to 400 and 500 mg/mL concentration of the Vernonia amygdalina dichloromethane extract [ 18 ]. Strawberry B. cinerea showed sensitivity to Cymbopogon martinii and Mentha spicata essential oils between 250 and 500 µL/L [ 10 ], and to Aloysia citriodora , C. winterianus , Lippia alba and Ocimum americanum oils at 0.8–1.4 mL/L [ 5 ].…”

“…With all the knowledge about pesticide residues in food, consumers tend to choose higher quality and more environmentally and human-safe products [ 5 ]. Therefore, alternative sources of antifungal substances are under investigation lately [ 6 , 7 , 8 , 9 , 10 , 11 ]. One alternative source is active compounds obtained from plants [ 12 ], such as botanical pesticides.…”

“…This pathogen infects many plant species and causes grey mould [ 23 , 24 , 25 ] during the growth phase and after harvest [ 18 ]. It is responsible for one of the most significant economic losses of horticultural crop production [ 1 , 4 , 10 ]. Genetic differences between B. cinerea cryptic species group II isolates from different plant hosts were indicated in previous studies [ 23 ].…”

New agricultural strategies aim to reduce the use of pesticides due to their damage to the environment and humans, and the caused resistance to pathogens. Therefore, alternative sources of antifungal compounds from plants are under investigation lately. Extracts from plants have a wide composition of chemical compounds which may complicate the development of pathogen resistance. Botrytis cinerea, causing grey mould, is an important horticultural and ornamental pathogen, responsible for the relevant yield and quality losses. B. cinerea isolated from a different plant host may differ in the sensitivity to antifungal substances from plants. Assessing the importance of research covering a wide range of pathogens for the rapid development of biopesticides, this study aims to determine the sensitivity of the B. cinerea isolate complex (10 strains) to plant extracts, describe morphological changes caused by the extract treatment, and detect differences between the sensitivity of different plant host isolates. The results showed the highest sensitivity of the B. cinerea isolates complex to cinnamon extract, and the lowest to laurel extract. In contrast, laurel extract caused the most changes of morphological attributes in the isolates. Five B. cinerea isolates from plant hosts of raspberry, cabbage, apple, bell pepper, and rose were grouped statistically according to their sensitivity to laurel extract. Meanwhile, the bell pepper isolate separated from the isolate complex based on its sensitivity to clove extract, and the strawberry and apple isolates based on their sensitivity to cinnamon extract.

“…The morphology of mycelium B. cinerea grown on strawberry fruit surfaces treated with moringa FO (Figure 5e) was abnormal growth, lysis, shrinkage, reduced hyphal length and diameters with lower production of conidia compared to the control treatment. Recently, our group and various publications have documented the antifungal activity of EOs and plant extracts including rosemary, peppermint, bay, basil, tea tree, celery seed fennel and Cinnamomum camphora [2,16,41,88]. The in vitro result showed that the EOs could be candidates for a natural antifungal in food preservation technology.…”

Post-Harvest Enhancing and Botrytis cinerea Control of Strawberry Fruits Using Low Cost and Eco-Friendly Natural Oils

et al. 2021

This work investigates an experimental study for using low-cost and eco-friendly oils to increase the shelf life of strawberry fruit. Three natural oils were used: (i) Eucalyptus camaldulensis var obtuse, (ii) Mentha piperita green aerial parts essential oils (EOs), and (iii) Moringa oleifera seeds n-hexane fixed oil (FO). Furthermore, a mixture of EOs from E. camaldulensis var obtusa and M. piperita (1/1 v/v) was used. The treated fruits were stored at 5 °C and 90% relative humidity (RH) for 18 days. HPLC was used to analyse the changes in phenolic compounds during the storage periods. The effects of biofumigation through a slow-release diffuser of EOs (E. camaldulensis var obtusa and M. piperita), or by coating with M. oleifera FO, were evaluated in terms of control of post-harvest visual and chemical quality of strawberry fruits. The post-harvest resistance of strawberry fruits to Botrytis cinerea fungal infection was also evaluated. As a result, the EO treatments significantly reduced the change in visual and chemical quality of strawberry fruit. Additionally, changes in the titratable acidity of moringa FO-coated strawberry fruits were delayed. EO treatments improved total soluble solids, total phenols, ascorbic acid, antioxidants and peroxidase. E. camaldulensis var obtusa and M. piperita (1/1 v/v) EO-vapour fruit exhibited a slower rate of deterioration, compared to other treatments in all tested, in two experiments. The lowest colour change (ΔE) was observed inthe fruit treated with E. camaldulensis var obtusa EO and M. oleifera FO. HPLC showed changes in phenolic compounds’ concentration, where p-coumaric acid, caffeic acid, gallic acid, ferulic acid and ellagic acid were mostly identified in the fruits treated with the oils. SEM examination confirmed the potential decrease in fungal growth as the fruits were treated with EOs. In conclusion, the treatment of EOs during different storage periods showed promising characterisations for strawberry fruit quality.

Arrowroot starch (AA)-based lms incorporated with a carnauba wax nanoemulsion (CWN), cellulose nanocrystals (CNCs), and essential oils (EOs) from Mentha spicata (MEO) and Cymbopogon martinii (CEO) were produced using the casting technique and then characterized in terms of their water barrier, tensile, thermal, optical, and microstructural properties and in vitro antifungal activity against Rhizopus stolonifer and Botrytis cinerea. Whereas the incorporation of CNCs decreased the moisture content and water vapor permeability of the AA/CWN/CNC lm, the additional incorporation of either EO decreased the transparency and affected the microstructure of the AA/CWN/CNC/EO nanocomposites. MEO and CEO incorporation improved the thermal stability of the lms and provided excellent protection against fruit-spoiling fungi. Because of their excellent barrier properties against fungal growth, water vapor permeability, and ultraviolet and visible light, these AA/CWN/CNC/EO lms have promising potential for application as active food packaging or coating materials.
