“…The bioprospecting assay unveils the vast inhibitory effect of cinnamon extract. This plant extract has already been reported for its antifungal activity on F. oxysporum, F. verticillioides, F. proliferatum and F. graminearum, with irreversible ultrastructural alterations, inhibition of enzymatic reactions of cell wall synthesis, interference with lipid membranes of fungal cells, increasing of cation permeability in membranes and affection of secondary metabolites production (Velluti et al 2004;Xing et al 2014a;Xing et al 2014b;Guo et al 2020). Our results support these observations regarding the antifungal activity of cinnamon extract and reports for the rst-time activity against Foc (race 1 and TR4).…”

Fusarium wilt of banana (FWB) caused by soil-borne Fusarium oxysporum f.sp. cubense (Foc), is a widely distributed disease that generates devastating losses in banana. The most aggressive Foc tropical race 4 (TR4), attacks Cavendish clones and a diverse range of other banana varieties. Management practices to suppress Foc are emerging, however they are challenging. Therefore, enhancing biological control activities could potentiate FWD control practices. Here we determine the antifungal synergistic effect of plant-based cinnamon (Cinnamomum zeylanicum) extract and Bacillus tequilensis EA-CB0015 cyclic lipopeptides against Fusarium sp. strains in vitro and in banana plants in greenhouse. We found, through a bioprospecting assay of 17 plant-based natural extracts, that cinnamon was highly active against Foc isolate IB (race 1). Furthermore, cinnamon and cyclic lipopeptides inhibited different Fusarium spp. strains belonging to race 1 and TR4, and their combination increased 1.4-fold the effect of the single extracts in vitro. Our results demonstrate that soil concentration of F. odoratissimum TR4-II5 was reduced by 78.5% with the combination treatment in a soil microcosm system. Although, while the combination reduced external FWB symptoms, only cinnamon extract had a significant impact on internal symptoms in plants. Taken together, the biological control effect of cyclic lipopeptides with cinnamon extract on Fusarium spp. supports their function towards increasing soil health and reducing disease intensity and suggests that the combination enhances the effect of the single extracts.

“…A considerable number of composite materials have been reported to maintain biological activity, inhibit volatility, and increase the effective utilization rate [12]. It has been reported that mesoporous silica with an ultra-high specific surface area of 1036.5 m 2 /g was used as a carrier for cinnamaldehyde [13]. Mesoporous composites of microcrystalline cellulose and zeolitic imidazole frameworks with a surface area of 236.2 m 2 /g were used for the temperature-controlled release of essential oils [14].…”

Citral (Eo) exhibits excellent fungicidal activities. However, it is difficult to maintain long-term fungicidal activity due to its strong volatility. Herein, a controlled-release strategy by using biomass-derived porous carbon (BC) was developed to overcome the drawback of Eo. New composite materials were prepared by loading Eo on tea stem porous carbon (BC@Eo), and their controlled-release fungicidal activity against Exobasidium vexans was assessed. BC with a large specific surface area of 1001.6 m 2 /g and mesoporous structure was fabricated through carbonization temperature of 700°C. The BC@Eo materials were characterized using Fourier-transform infrared spectroscopy and X-ray powder diffraction. The results suggested that chemical and physical interactions occurred in BC@Eo. The Eo release profile suggested a biphasic pattern with an initial fast release on days 1-14 and a subsequent controlled phase on days 14-30. The in vitro cumulative release percentage of Eo from BC@Eo was 51% during one month, and this result was significantly lower than that from free Eo (cumulative release percentage of Eo of 82% in one week). The antifungal activities of Eo and BC@Eo against E. vexans were determined using the inhibition zone method. The results indicated that Eo and BC@Eo formed large inhibition zones of 19.66 ± 0.79 and 21.92 ± 0.77 mm, respectively. The influence on the hyphal structure of E. vexans was observed by scanning electron microscopy on day 30. The hyphal structure of E. vexans treated with BC@Eo was more shrunken than that treated with Eo at 30 days, suggesting that BC@Eo prolongs the fungicidal activity against E. vexans. This study demonstrated that the encapsulation of Eo in BC for developing the BC@Eo materials could be a promising strategy to inhibit volatility and maintain the fungicidal activity of Eo and provide a potential alternative for the reuse of abundant tea biomass waste resources.
