Fusarium spp. are among the most destructive soil-borne fungal pathogens affecting chilli production and remain difficult to control using conventional approaches. This study reports a preliminary in vitro observation of the inhibitory activity of a combined acetogenin–curcumin extract against Fusarium spp. Acetogenin was obtained from soursop leaves (Annona muricata L.), while curcumin was derived from turmeric (Curcuma longa L.). The study involved extract preparation, fungal isolation, functional group identification, and antifungal assays using different extract ratios. Morphological observations confirmed that the isolated pathogen was consistent with Fusarium spp. Among the tested formulations, the extract combination containing 60% acetogenin and 40% curcumin showed the highest inhibitory activity, reducing fungal colony growth by up to 84% compared to the control. These findings provide an initial indication that a combined acetogenin–curcumin extract may enhance in vitro inhibition of Fusarium spp. and support further investigation using replicated assays and extended evaluations.
