Abstract
Ramularia blight, caused by the fungal pathogen Ramularia
foeniculi, poses a significant threat to fennel (Foeniculum vulgare)
cultivation, impacting yield and quality. This study investigated the efficacy
of various medicinal plant extracts and soil additives as sustainable
alternatives to synthetic fungicides for managing this disease. We tested
aqueous extracts of neem (Azadirachta indica), garlic (Allium sativum),
and thyme (Thymus vulgaris) alongside soil amendments including
vermicompost and biochar. Treatments were applied to fennel plants in a
controlled greenhouse environment and monitored for disease incidence and
severity over a 12-week period. Our results indicated that the thyme extract
and biochar-amended soil treatments significantly reduced disease severity
compared to the untreated control. Specifically, the thyme extract treatment
exhibited a 65% reduction in disease severity, while the biochar treatment
showed a 52% reduction. These findings suggest that certain plant-based
extracts and soil additives can serve as effective, environmentally friendly
tools for managing Ramularia blight, offering a promising approach for organic
and sustainable fennel production.
