Antifungal activity of lipid fractions of medicinal plants against Furasium isolates from infected garlic cloves [Articol]

Abstract

Garlic (Allium sativum L.) is widely cultivated for its culinary and medicinal value but is highly susceptible to fungal diseases, particularly those caused by Fusarium species. This study evaluated the antifungal activity of lipid fractions from seven medicinal plants against Fusarium isolates obtained from infected garlic cloves. The lipid fractions were added to PDA medium and fungal growth was monitored over nine days. The lipid fractions of Eucalyptus mellidora and Salvia officinalis significantly reduced mycelial growth of both isolates compared to the control, suggesting strong antifungal potential. Other oils exhibited moderate or low activity. These findings support the potential use of selected plant-derived lipid fractions as natural fungicides in garlic protection. Further research is needed to validate efficacy under field conditions.
