“…Several previous studies have highlighted the antimicrobial potential of C. citratus EO. For example, Agbé mé bia et al [24] demonstrated the efficacy of C. citratus EO against A. niger, C. albicans, C. kefir, C. tropicalis, R. nigricans and S. cerevisiae KVL013. Also, Kpatinvoh et al [17] revealed that C. citratus EO strongly inhibits the growth of Aspergillus flavus, a cowpea contaminant, at an MIC of 0.05 µl/ml.…”

Papaya cultivation is considered to be one of the most important fruit-growing activities in Cameroon, and plays a vital role in improving the livelihoods of local producers. However, leaf diseases caused by devastating fungi are a real obstacle to the development of this crop. The aim of this study was to evaluate the antifungal potential of Cymbopogon citratus essential oil against Alternaria alternata and Phomopsis carica-papayae, fungal agents associated with the deterioration of papaya leaves in the Moungo region of Cameroon. The essential oil of fresh C. citratus leaves was extracted by hydrodistillation. Analysis of the chemical composition by GC then GC/MS revealed Geranial (45.24%), Neral (35.57%) and Myrcene (7.21%) as the majority compounds. In vitro antifungal tests on mycelial growth by incorporation into agar gave MICs of 900 ppm and 700 ppm against A. alternata and P. carica-papayae respectively. The MIC of 700 ppm proved fungicidal on P. carica papayae, while for A. alternata the fungicidal effect was obtained at a concentration of 900 ppm. In situ, the essential oil proved significantly active in inhibiting necrosis caused by the conidial complex of the two pathogens on papaya leaves, with a percentage inhibition of 85.93% at a concentration of 6000 ppm. C. citratus EO could therefore be used as an alternative to chemical fungicides in the fight against papaya leaf disease pathogens.

“…Stapf is neral (NR), which is the cis ‐isomer of citral and also referred to as β ‐citral 17 . Cymbopogon citratus essential oil has been reported to have antioxidant, antifungal, and antimicrobial activities 18–21 . In addition, a high concentration of C. citratus essential oil significantly inhibited seedling growth and interfered with photosynthetic metabolism of Echinochloa crus‐galli leaves 22 .…”

BACKGROUNDThe use of herbicide safeners effectively minimises crop damage while maintaining the full efficacy of herbicides. The present study aimed to assess the potential protective effects of neral (NR) as a safener, in order to mitigate injury caused by fenoxaprop‐p‐ethyl (FE) on rice.RESULTSThe alleviating effect of NR was similar to that of the safener isoxadifen‐ethyl (IE). The root elongation of rice was significantly promoted under the FE + NR and FE + IE treatments, as compared to the FE treatment. The transcriptome analysis further suggested that the effects of NR treatment on plant metabolic pathways differed from those of IE treatment. In total, 895 and 47 up‐differentially expressed genes induced by NR (NR‐inducible genes) and IE (IE‐inducible genes) were identified. NR‐inducible genes were mainly enriched in phytohormone synthesis and signalling response, including ‘response to brassinosteroid’, ‘response to jasmonic acid’, ‘response to ethylene’, ‘brassinosteroid metabolic process’, ‘brassinosteroid biosynthesis’ and ‘plant hormone signal transduction’. In contrast, IE‐inducible genes were predominantly enriched in glutathione metabolism. The activity of glutathione S‐transferase was found to be increased after IE treatment, whereas no significant increase was observed following NR treatment. Moreover, several transcription factor genes, such as those encoding AP2/ERF‐ERF and (basic helix–loop–helix) bHLH were found to be significantly induced by NR treatment.CONCLUSIONThis is the first report of the utilisation of NR as an herbicide safener. The results of this study suggest the toxicity of FE to rice is mitigated by NR through a distinct mechanism compared to IE. © 2023 Society of Chemical Industry.
