“…Plants produce a broad spectrum of secondary metabolites, such as alkaloids, phenols, quinones, flavonoids, glycosides, saponins, tannins, and terpenoids [9]. The roles of these bioactive compounds include inducing plant defence system against pathogen attacks during which their concentration in plants depends on pathosystem and environmental conditions [10]. Previous studies have reported that plant-derived products from members of the genera Acacia, Cupressus, Eucalyptus, Nerium, and Schinus possess strong antifungal activities against a broad spectrum of plant pathogenic fungi [10][11][12][13][14].…”

Background “Bayoud” disease caused by Fusarium oxysporum f. sp. albedinis (Foa) poses a serious threat to date palm (Phoenix dactylifera L.) in Morocco. However, research studies performed to discover biological methods to control this disease remain limited. The present study has set objectives to determine antifungal activity of five plants extracts (Acacia cyanophylla, Cupressus atlantica, Eucalyptus torquata, Nerium oleander, and Schinus molle) against Foa and link this effect to their content in polyphenols and flavonoids as well as their antioxidant properties. Results Plant extracts showed significant differences (p < 0.05) regarding their antifungal activity. The extracts of E. torquata and C. atlantica showed the strongest antifungal effect resulting in the inhibition of mycelial growth, sporulation, and spore germination in a dose-dependent manner. In addition, there were significant differences among the examined plant extracts in respect to their total polyphenols (1.536–7.348 g GAE/100 g DW), flavonoids (0.986–5.759 g RE/100 g DW), and antioxidant properties measured by Trolox equivalent antioxidant capacity (TEAC) (7.47–38.97 mmol TE/100 g DW) and ferric-reducing antioxidant power (FRAP) assay (8.95–47.36 mmol TE/100 g DW). Moreover, the antifungal potential of plant extracts was found to be moderately to strongly correlated with their polyphenol and flavonoid contents as well as their antioxidant activity, implying that the effective inhibitory activity of these plant extracts is partly due to their richness in antioxidative secondary metabolites. Conclusion Our findings shed further light on plants as a-yet-untapped resource of bioactive compounds and constructed the foundation for the development of new biological approaches to best manage Bayoud disease.

The aim of the present study is to identification and classification of different associated fungi from the seeds of Eruca sativa. Total 10 species of fungal pathogens belonging to 7 genera are isolated from the Saudi (Ss) and Indian seeds of Eruca sativa. Saudi seeds affected by the fungal pathogens namely, A. niger, A. flavus, A fumigates, Mucor spp., Pencillium spp., while Indian seeds affected by Aspergillus niger, A. flavus, A. fumigates, Aspergillus terreus, Pencillium spp., Mucor spp., Rhizopus stolonifer, Humicola insolens, Colletotrichum gloeosporioides, Fusarium oxysporum. However, many of the soil borne or seed borne associated fungal pathogens spread the diseases in plants as well as in human beings. So the present study reveals that, the proper identification of fungal pathogens and their symptoms are easily recognized. Then the prevention care could be taken during the agriculture and high yield produced before the spread of symptoms and diseases.

Rice is a plant that has been intensively breed, especially in Asia, most of the population’s staple food is rice. There were Many types of rice varieties have been developed for high yeald production. Different rice diseases arise that many treat to reduce production. Such as curvularia spotting disease caused by the fungus Curvularia sp. Infection of Curvularia species causing leaf spots, leaf blights, kernel root, grain deformation and other diseases are well known globally. It was discovered that the small brown oval spots on the Ciherang rice variety cultivated in Bali, Indonesia was caused by Curvularia verruculosa. This disease could reduce the rice yield up to almost 50%. The application of commercial fungicide by the local farmers has not been satisfactorily successful in term of controlling the disease but instead bring damages to the environment and the soil as well. Farmer’s safety is also another serious issue. The current studi develop a natural and green fungicide to check the efficacy of Piper caninum extract against the fungi. Research in the laboratory uses a completely randomized design and research in the field uses a randomized group design.The method of making leaf extracts uses maceration method. Diffusion well technique showed a strong inhibition of the abstract against the C. verruculosa with 22mm inhibition. Zone with a total inhibition of 4% extract concentration. The minimum inhibitory concentration (MIC) was low of 0.5%. Scanning electron images of the treated fungi showed hollow and wrinkled mycelia morphology indicating lysis of the cell has occurred. P. caninum leaf extract at a concentration of 3% provides the highest obstacle to the intensity of C. verruculosa disease, whereas in the treatment of leaf extract concentration p. caninum 4% intensity of C. verrucuosa disease has decreased because rice plants are toxic at a concentration of 4%. Further research is needed regarding the treatment of P. caninum leaf extract against C. verruculosa in rice fields.
