“…It is desirable that the assays also determine the potential fungicidal effect of the extracts and/or compounds. Many plant extracts have demonstrated potent antifungal activity (with MIC values below 1.0 mg/mL) using in vitro assays (Table 2), but only a few were tested in vivo [130,[222][223][224][225][226][227]. The potent in vitro antifungal activity of Melia azedarach, Combretum erythrophyllum and Quercus acutissima leaf extracts [130] were confirmed in vivo.…”

Many Fusarium species are pathogenic, causing crop diseases during crop production and spoilage of agricultural products in both commercial and smallholder farming. Fusarium attack often results into food contamination, yield loss and increases in food insecurity and food prices. Synthetic fungicides have been used as a control strategy for the management of crop diseases caused by Fusarium pathogens. The negative effects associated with application of many synthetic pesticides has necessitated the need to search for alternative control strategies that are affordable and environmentally safe. Research on medicinal plants as control agents for Fusarium pathogens has received attention since plants are readily available and they contain wide variety of secondary metabolites that are biodegradable. The activities of solvent extracts, essential oils and compounds from medicinal plants have been tested against Fusarium phytopathogenic species. A summary of recent information on antifungal activity of plants against Fusarium species is valuable for the development of biopesticides. This paper reviews the antifungal research conducted on medicinal plants against Fusarium pathogens, over a 10-year period, from January 2012 to May 2021. We also highlight the challenges and opportunities of using natural products from medicinal plants in crop protection. Several databases (Science Direct and Web of Science) were used to obtain information on botanical products used to control Fusarium diseases on crops. Keywords search used included natural products, antifungal, Fusarium, crops diseases, phytopathogenic, natural compounds and essential oil.

“…In assessing the growth rates of the isolated fungal species on solid agar media, no clearing zones with abiotic control samples were found, which means that the clearance zones resulted from fungal action and not because of other abiotic factors ( Table 2 ). Previous studies showed these clear zones were produced by an extracellular lipase enzyme, which catalysis hydrolysis reactions of the fats and maintain thermal flexibility around the site of microbial activity [ 33 ]. To test the hydrocarbon tolerance of each fungal species, the species were cultured on solid MSM media ( Figure 1 ).…”

Background: Microbial biodegradation of oil-hydrocarbons is one of the sustainable and cost-effective methods to remove petroleum spills from contaminated environments. The current study aimed to investigate the biodegradation abilities of three Fusarium isolates from oil reservoirs in Saudi Arabia. The novelty of the current work is that the biodegradation ability of these isolates was never tested against some natural hydrocarbons of variable compositions, such as Crude oil, and those of known components such as kerosene and diesel oils. Methods: The isolates were treated with five selected hydrocarbons. The hydrocarbon tolerance test in solid and liquid media was performed. The scanning electron microscope (SEM) investigated the morphological changes of treated fungi. 2, 6-Dichlorophenol Indophenol (DCPIP), drop collapse, emulsification activity, and oil Spreading assays investigated the biodegradation ability. The amount of produced biosurfactants was measured, and their safety profile was estimated by the germination assay of tomato seeds. Results: The tolerance test showed enhanced fungal growth of all isolates, whereas the highest dose inhibition response (DIR) was 77% for Fusarium proliferatum treated with the used oil (p < 0.05). SEM showed morphological changes in all isolates. DCPIP results showed that used oil had the highest biodegradation by Fusarium verticillioides and Fusarium oxysporum. Mixed oil induced the highest effect in oil spreading, drop collapse, and emulsification assay caused by F. proliferatum. The highest recovery of biosurfactants was obtained by the solvent extraction method for F. verticillioides (4.6 g/l), F. proliferatum (4.22 g/l), and F. oxysporum (3.73 g/l). The biosurfactants produced by the three isolates stimulated tomato seeds’ germination more than in control experiments. Conclusion: The current study suggested the possible oil-biodegradation activities induced by three Fusarium isolates from Riyadh, Saudi Arabia. The produced biosurfactants are not toxic against tomato seed germination, emphasizing their environmental sustainability. Further studies are required to investigate the mechanism of biodegradation activities and the chemical composition of the biosurfactants produced by these species.

“…Las cepas de hongos aisladas de plantas de frijol con síntomas de marchitez y pudrición de raíz fueron identificadas por características morfológicas. Se observó micelio algodonoso con tonos purpuras a partir de los cuatro días de edad, las características microscópicas fueron microconidios sin septos, ovales, elípticos a reniformes (Khan et al, 2021). Las clamidosporas de posición intercalar y terminal, individualmente o en pares, con una apariencia lisa circular de doble pared.…”

El cultivo del frijol es afectado por diversas enfermedades en las que destaca la marchitez causada por Rhizoctonia solani y Fusarium spp. El manejo de estos patógenos principalmente se realiza mediante el uso de compuestos químicos los cuales contaminan el ambiente, son tóxicos para el humano, desarrollan resistencia en los fitopatógenos y además aumentan los costos de producción. El objetivo del presente estudio fue evaluar la respuesta de inducción de resistencia mediante la inoculación de bacterias endófitas contra R. solani y F. oxysporum. Se utilizaron plantas de frijol de 45 días de edad para determinar la concentración de proteínas (PR) y la actividad de peroxidasa (POD), fenilalanina amonio liasa (PAL) a las 6, 12, y 24 h después de la inoculación de los consorcios. Los resultados evidenciaron que los microorganismos endofíticos promueven los mecanismos de defensa en frijol, pudiendo propiciar resistencia contra F. oxysporum y R. solani.
