“…The principal components of this study explained only about 36% of the total variance. According to Sampaio et al (2016), the use of many variables for the analysis may generate this low explanation of the principal components. High positive correlation was observed between some constituents of the essential oil of the studied plants (Table 3).…”

“…Recent studies have demonstrated the efficacy of this compound as an antifungal agent, and it has been used against the causative agent of post-harvest diseases in Citrus sp, such as green mold (Penicillium digitatum), sour rot (Geotrichum citri-aurantii), and blue mold (Penicillium italicum) (SADDIQ et al, 2010;ZHENG et al, 2015, ZHOU et al, 2014TAO et al, 2014). Sampaio et al (2016) reported citral as one of the major compounds of the essential oil of M. ovata leaves (68.5%), which completely inhibited the fungus F. solani, causing its mortality at concentrations from 0.5 mL/L. Studies suggest that citral is responsible for the modification in the mitochondrial morphology and the cellular wall function of these phytopathogens, causing a decrease in the O2 level and respiratory rate and, consequently, leading to an increase in the permeability of the fungal membrane on the cell wall.…”

“…Studies suggest that citral is responsible for the modification in the mitochondrial morphology and the cellular wall function of these phytopathogens, causing a decrease in the O2 level and respiratory rate and, consequently, leading to an increase in the permeability of the fungal membrane on the cell wall. Sampaio et al (2016) reported the antifungal activity of the essential oil of a Myrcia ovata chemotype (MYRO-006) with 58.27% of (E)nerolidol, which showed 47.50% mycelial growth inhibition against F.solani. The alcohol (E)nerolidol, present as a major compound in the essential oil of Piper chaba Hunter (5.1%), showed activity against the fungi Rhizoctonia solani, Botrytis cinerea, F. solani, F. oxysporum, Sclerotinia sclerotiorum, and Phytophthora capsici, causative agents of plant diseases, with minimum inhibitory concentrations between 125 and 500 μL mL -1 (RAHMAN et al, 2011).…”

This work evaluated the antifungal activity of essential oils of Myrcia ovata chemotypes (MYRO-175, MYRO-156, MYRO-154, MYRO-165, and MYRO-015) and their major compounds (linalool, geraniol, citral, and (E)-nerolidol) on the phytopathogenic fungi Fusarium pallidoroseum (which causes melon postharvest rot) and Colletotrichum musae (which causes anthracnose in banana). The essential oils were obtained by hydrodistillation and analyzed by GCMS/FID. To evaluate the antifungal activity, the essential oils and their major compounds were tested at different concentrations (0.1; 0.3; 0.4; 0.5; 0.7; 1.0; 3.0, and 5.0 mL/L). The major compounds found in the essential oils were nerolic acid, linalool, geraniol, citral, and (E)-nerolidol. The essential oils of the plants MYRO-154, MYRO-165, and MYRO-015 had the minimum inhibitory concentration (MIC) (0.3 mL/L) for F. pallidoroseum and the lowest minimum fungicidal concentration (MFC) (0.7 mL/L), for C. musae. Geraniol and citral had the lowest MFC (0.5 mL / L) for the two fungi tested. For F. pallidoroseum, the essential oils of the chemotypes were more effective than their major compounds. Conversely, the major compounds geraniol of the chemotype MYRO-156 (74.37%) and citral were more effective than their respective essential oils for C. musae. (E)-nerolidol and geraniol of the chemotype MYRO-015 (33.15%) were responsible for the antifungal activity of the essential oils of their respective chemotypes.

This work aimed to evaluate the in vitro antifungal activity of the essential oils of L. alba belonging to the carvone chemotype (LA-13 and LA-57) and the citral chemotype (LA-10, LA-29, and LA-44); the carvone enantiomers (R)-(-)-carvone and (S)-(+)-carvone; and citral on phytopathogenic fungi Lasiodiplodia theobromae (LT), Fusarium pallidoroseum (FP) and Fusarium solani (FS). Concentrations of 0.01; 0.05; 0.1; 0.2; 0.3; 0.5 and 1.0 mL/100 mL were tested, and the percentage of mycelial growth inhibition (MGI) was calculated after 96h in relation to the control. Minimal Inhibitory Concentrations (MIC) and Minimal Fungicide Concentrations (MFC) were obtained for essential oils and compounds. From the concentration of 0.2 mL/100 mL, all the accessions and carvone enantiomers were effective against the fungus LT, except the accession LA-44, for which the maximum inhibition occurred from the concentration of 0.3 mL/100 mL. Citral was the most effective compound against LT, with 100% of MGI from the concentration of 0.05 mL /100 mL. All accessions and enantiomers caused 100% of MGI against FP fungus from the concentration of 0.2 mL/100 mL. Once again, citral stood out by providing the same result as the other treatments from the concentration of 0.1 mL/100 mL. Considering the fungus FS, carvone enantiomers and citral caused 100% of MGI from the concentration of 0.1 mL/100 mL while all accessions caused 100% of MGI from the concentration of 0.2 mL/100 mL. Citral and carvone enantiomers presented the lowest MIC values (0.1 mL/100 mL) against FS fungus. The MIC of citral for LT and FP were not determined at the concentrations tested. (R)-(-)-carvone enantiomer presented the lowest MIC (0.1 mL/100 mL) for the LT fungus. Most of the other accessions presented MIC of 0.2 mL/100 mL for the three fungi. In relation to the minimum fungicidal concentration (MFC), citral stood out with values from 0.05 mL/100 mL (LT). Citral and carvone presented the same MFC for FS (0.2 mL / 100 mL). The other accessions showed MFC values from 0.3 mL/100 mL for the three fungi. Essential oils of L. alba accessions, carvone enantiomers, and citral were efficient in phytopathogen control and could be considered as an alternative to fungicides for presenting inhibitory and fungicidal effect against these microorganisms at low concentrations.
