Abstract
Post-harvest fungal contamination in grains and tubers presents a significant threat to food security and public health due to the production of toxic mycotoxins. This study focused on isolating and identifying fungal pathogens from potato and maize samples collected across various regions in Qena, Upper Egypt. The most prevalent isolates were Aspergillus flavus and Fusarium semitectum. To evaluate potential control strategies, the antagonistic effects of the biocontrol agent Trichoderma harzianum, along with turmeric (Curcuma longa) powder, its essential oil, and curcumin, were assessed. Dual culture assays revealed that Trichoderma exhibited strong inhibitory activity against both pathogens, with inhibition rates reaching up to 92%. Similarly, turmeric powder (5%), turmeric oil (0.4%), and curcumin (1%) demonstrated significant antifungal effects, achieving inhibition rates of up to 89.76%. Notably, co-application of Trichoderma with turmeric resulted in synergistic enhancement of fungal suppression. Based on these findings, two practical formulations were developed: one combining Trichoderma, talc powder, and carboxymethyl cellulose (CMC), and another enriched with Curcuma longa powder. These formulations were applied as seed coatings for maize and potato, offering a sustainable and eco-friendly approach to post-harvest fungal control. The study underscores the potential of integrating microbial and plant-based agents as effective biocontrol solutions, contributing to improved food safety, public health, and environmental sustainability.
