Cylindrocladium reteaudii (Bugnic.) Boesew. is a severe pathogen which can cause leaf blight disease in Eucalyptus seedlings in tropical countries. This study investigated the antifungal activity of essential oils extracted from Acorus calamus L. rhizomes in inhibiting the growth of C. reteaudii, both in in vitro and in vivo experiments. The extraction of essential oils from rhizomes was carried out by hydro-distillation technique and the in vitro antifungal testing was done by using the poisoned food technique. The results indicated that an essential oil concentration of 2,000 ppm can completely inhibit the fungal growth with a 50% inhibitory concentration value of 54.76 ppm. For the in vivo experiment, it was found that an essential oil concentration of 500 ppm and Captan® of 1,000 ppm were not significantly different in inhibiting the growth of C. reteaudii. However, these two treatments significantly inhibited the fungal growth (p<0.05) when compared with the control treatments. Physiological and anatomical characteristics were investigated to check for the antifungal activity after the application of essential oils. Results showed that essential oil spraying had no effect on the leaf transpiration rate and temperature of the Eucalyptus seedlings, but the incident disease ratio was high when an essential oil concentration of more than 1,500 ppm was applied. Therefore, it can be inferred that the essential oils from A. calamus rhizomes at an optimum concentration can be an efficient antifungal compound with a potential to control leaf and shoot blight diseases in Eucalyptus seedlings in a nursery.

Background. Echinops kebericho is an endemic medicinal plant in Ethiopia widely used in the treatment of infectious and noninfectious diseases. Essential oils are known for their antibacterial, antifungal, antiviral, insecticidal, and antioxidant properties. This study evaluated the antifungal activity of essential oil from E. kebericho against four common pathogenic fungi and two standard strains. Methods. The essential oil was obtained by hydrodistillation. The antifungal screening was done by agar well diffusion method. Minimal inhibitory concentrations (MICs) were determined by broth microdilution. Minimal fungicidal concentrations (MFCs) were determined by subculturing fungal strains with no visible growth onto a Sabouraud dextrose agar (SDA) plate. Results. Candida albicans and Cryptococcus neoformans were highly sensitive while Aspergillus flavus did not show sensitivity up to 1 mg/ml of essential oil; MICs ranged from 0.083 mg/ml to 0.208 mg/ml. Concentration and fungal species showed significant dose-dependent associations ( p < 0.0001 ) with antifungal activity. The MICs of essential oil were comparable to those of the standard drug (fluconazole) against C. glabrata and C. krusei. The lowest MFC of the essential oil was observed against Candida parapsilosis (0.145 mg/ml) while the highest MFC was against Candida krusei (0.667 mg/ml). Conclusion. Echinops kebericho essential oil showed noteworthy antifungal activity against Cryptococcus neoformans, Candida albicans, and Candida glabrata and could be a potential candidate for further antifungal drug development.

The objective of this study was to evaluate the antifungal activity of essential oil (EO) ofEucalyptus camaldulensisDehnh. against fiveFusariumspp. commonly associated with maize.The essential oil had been extracted by steam distillation in a modified Clevenger-type apparatus from leaves ofE. camaldulensisand their chemical composition characterized by gas chromatography mass spectrometry. Poisoned food technique was used to determine the percentage inhibition of mycelial growth, minimum inhibitory concentration, and minimum fungicidal concentration of the EO on the test pathogens. Antifungal activity of different concentrations of the EO was evaluated using disc diffusion method. The most abundant compounds identified in the EO were 1,8-cineole (16.2%),α-pinene (15.6%),α-phellandrene (10.0%), and p-cymene (8.1%). The EO produced complete mycelial growth inhibition in all the test pathogens at a concentration of 7-8 μL/mL after five days of incubation. The minimum inhibitory concentration and minimum fungicidal concentration of the EO on the test fungi were in the range of 7-8 μL/mL and 8–10 μL/mL, respectively. These findings confirm the fungicidal properties ofE. camaldulensisessential oils and their potential use in the management of economically importantFusariumspp. and as possible alternatives to synthetic fungicides.

AbstractBiocompounds are promising tools with the potential to control pathogenic microorganisms. The medicinal plant species Ocotea odorifera, Ocotea puberula and Cinnamodendron dinisii, distributed along Brazilian biomes, are sources of chemical compounds of biological interest. This study aimed to evaluate the antifungal activity of the essential oils of O. odorifera, O. puberula and C. dinisii essential oils upon the mycotoxin producers Alternaria alternata, Aspergillus flavus and Penicillium crustosum. The essential oils where characterized by gas chromatography coupled to mass spectrometer (CG-MS). The majority compounds identified were: safrol (39.23%) and camphor (31.54%) in O. odorifera, Beta-caryophyllene (25.01%) and spathulenol (17.74%) in O. puberula, and bicyclogermacrene (23.19%) and spathulenol (20.21%) in C. dinisii. The Minimal Inhibitory Concentration (MIC) of antifungal activity considered diameters higher than 10 mm after 72 h of incubation at 30 ºC. A. alternata presented higher resistance to O. odorifera and C. dinisii oils. The inhibitory effect of O. odorifera on A. flavus showed stabilization at oils concentrations between 50% and 80%, increasing at 90% and 100% (pure oil) treatments. We observed that the essential oils of O. odorifera and C. dinisii have potential in the control of the analyzed fungi species. The essential oil of O. odorifera presented a better activity in all the assays, which can be related to the presence of safrole and phenylpropenes, compounds with known antifungal activity.
