“…For instance, under dry conditions, the foliar application of clove fruit extract and/or salicylic acid to potato tubers was shown to enhance growth characteristics as well as defensive antioxidant components, with similarly enhanced features noted when folic acid, ascorbic acid and salicylic acid were sprayed on the foliage of potato under salt stress conditions [59,60]. Different reports have highlighted a link between plant stress and pathogen infection [61,62], and, therefore, even though the antioxidant plant extracts in this study may not directly confer protection against plant pathogens, enhanced stress tolerance in response to their application may subsequently translate into lower susceptibility to the pathogens.…”

Background: Fusarium species, a group of economically destructive phytopathogens, are poorly studied in Mauritius where agriculture holds much significance. Furthermore, the increasing popularity of organic farming has prompted interest in alternatives to chemical fungicides. Methods: After gaining an overview of Fusarium prevalence in Mauritius fields through a survey, the pathogen was isolated from infected crops and identified based on morphological and molecular characteristics. Methanol and water extracts were then prepared from Melia azedarach, Ocimum gratissimum, cinnamon and cloves before determining their phytochemical profiles. Additionally, the antioxidant and antifungal effects of different concentrations of aqueous extracts were assessed. Results: The isolate was confirmed as Fusarium oxysporum, and cloves inhibited its growth by up to 100%, especially at 60 and 90 g/L, with the results being significantly higher than those of the synthetic fungicide mancozeb. Over 50% inhibition was also noted for cinnamon and Ocimum gratissimum, and these effects could be linked to the flavonoids, phenols and terpenoids in the extracts. Conclusion: This study presented the aqueous extracts of cloves, cinnamon and Ocimum gratissimum as potential alternatives to chemical fungicides. It also confirmed the prevalence of Fusarium infection in Mauritius fields, thereby highlighting the need for additional studies on the pathogen.
