Fusarium are considered as the major plant pathogen fungi, that cause the majority of soil-borne diseases to more than 100 plant species in the world, including maize. Thus, there are emerging demands of biocontrol reagents, and Crotalaria longirostrata showed fungicidal activity. The C. longirostrata branch extract was phytochemically characterized and evaluated for efficacy for the control of Fusarium wilt in maize. The application of the extract reduced the percentage of disease incidence significantly caused by Fusarium verticillioides from 70.4% to 40.12% as compared to non-treated plants, and evenly the disease severity was reduced from 40.15% to 29.46%. The phytochemical components of the extract were cinnamic acids (caffeic acid and ferulic acid) and phenolic acid (gallic acid). Furthermore, multiple structures were detected through mass spectrometry such as: phenols, alkaloids, esters, terpene, ketones, and amides. The bioautography assay showed that to separate the compounds of C. longirostrata branch extract causes it’s the loss of fungicidal activity. This is due to the synergy or additive interactions of secondary metabolites present in the raw extract. Our results suggest that the application of C. longirostrata branch extract is a promising strategy to be applied to the soil as a preventive treatment. View Full-Text
