Abstract:
Agriculture is a key pillar of Morocco's socio-economic framework, with the cereal sector playing a crucial role. Cereal yields are significantly affected by biotic and abiotic constraints, such as drought and fungal diseases, particularly root rot caused by Fusarium culmorum. To mitigate these issues, chemical treatments are commonly used; however, they pose environmental and human health risks.
This study explores an alternative approach by evaluating the synergistic effects of different concentrations of Origanum compactum essential oil and tetraconazole on Fusarium culmorum growth. Using the poisoned medium method, results showed that adding 0.29 mg/mL of Origanum compactum essential oil to tetraconazole achieved complete inhibition of Fusarium culmorum 1, while a lower concentration of 0.07 mg/mL was sufficient to inhibit Fusarium culmorum 2. This antifungal activity is primarily attributed to the high carvacrol content in the essential oil, known for its strong efficacy against phytopathogens.
