Abstract

Fusariumsolani and Rhizoctoniasolani are highly destructive soil-borne diseases that have a significant impact on agricultural productivity and quality on a global scale. Ginger, a significant medicinal plant, is utilized as a substitute for chemical fungicides and bactericides due to the properties of its rhizome extract. This work aims to demonstrate the antifungal and antioxidant effects of the phytochemical components found in ethanolic crude extracts derived from ginger rhizomes.The ethanolic extract of ginger rhizome underwent phytochemical examination, which detected the presence of flavonoids, alkaloids, terpenoids, tannins, polysaccharides, saponins, and glycosides. The ginger rhizome's ethanolic extract has a concentration of 573.87 mg GAE/100 g extract for total phenols (TPCs) and 232.43 mg QE/100 g extract for total flavonoids (TFCs). The DPPH radical scavenging activity exhibited a significant increase, rising from 13% to 89%, as the concentration of the extract was raised from 100 to 600 µg/mL. Our observation revealed that the ethanolic extract derived from ginger rhizome effectively suppressed the growth of F. solani and R. solani mycelium on solid agar medium Petri dishes. The degree of inhibition was found to be directly proportional to the concentration of the extract. Our research suggests that ginger has the potential to be a valuable source of natural antioxidants and antifungal substances
