Effect of Essential Oils Coating on Seed-borne Fungi in Maize Seeds
Main Article Content
Abstract
The aim of this study was to determine the efficiency of eugenol, star anise and galanga essential oils in controlling seed-borne fungi of maize seeds. First, the maize seeds were coated with a chitosan-lignosulphonate polymer followed by the essential oils of eugenol, star anise or galangal at various concentrations; 0.5, 1, 1.5 and 2 ml. Then, the coated seeds were stored for 90 days. Finally, the health of the stored, coated seeds was assayed by using the blotter method in which the fungal inhibition percentage was calculated. Of the three essential oils used in this study, eugenol proved to be the most effective antifungal agent against the pathogenic fungi. This study concluded that eugenal essential oil was effective in controlling and eliminating Aspergillus niger and Fusarium sp. in maize seeds when compared to the chemical captan.
