Antifungal Activity of Acetic Acid Applied as Volatile or Carrier Contact Assay to Management Storage Fungi of some Medicinal and Aromatic Seeds

Abstract

The most significant medicinal and aromatic plants in Egypt and the rest of the globe are caraway, cumin, and anise. Many fungi, including Aspergillus flavus, Aspergillus niger, and Fusarium verticillioides, attack and harm them after harvest and while they are being stored. At 7.5 μl/l, AA vapor suppressed the linear growth and spore germination of A. flavus and F. verticillioides, while 9.0
μl/l inhibited A. niger. AA solution at 0.75/L completely suppressed the mycelial growth and spore germination of A. flavus and F. verticillioides, while at 1.0 ml/L inhibited linear growth and spore germination of A. niger. Two methods i.e. Volatile assay (AA vapor) and Carrier contact assay (wheat bran carrier) were tested to suppress fungal infection of some medicinal and aromatic seeds. As for
volatile assay results showed that complete suppression of natural infection was obtained with AA at 250 ml /L. Followed by AA at 200 ml/L which reduced the natural infection by 77.0,80.0 and 79.0% for cumin, anis and caraway seeds respectively. Complete suppression of germination was obtained with AA at 250 ml /L. As for Carrier contact assay complete suppression of natural infection was obtained with AA at 25g/kg seeds. Followed by AA at 20 g/kg seeds ml/L which reduced the natural infection by 75.0,88.0 and 90.0% for cumin, anise and caraway seeds respectively. Complete suppression of germination was obtained with AA at 25 g/kg seeds.
