In vitro antifungal efficacies of aqueous extract of Dumortiera hirsuta (Swaegr.) Nees against sporulation and growth of postharvest phytopathogenic fungi
- The aqueous extract of Dumortiera hirsuta (Swaegr.) Nees, a bryophyte, was found to be effective against seven postharvest phytopathogens tested. The fungitoxicity of the extract was measured by percent spore germination inhibition and percent radial growth inhibition using poisoned food technique. The inhibition of spore germination by the Dumortiera extract was within the range of 400 to 550 ppm. In poisoned food technique, out of seven postharvest phytopathogenic fungi tested six were completely inhibited by the Dumortiera extract with concentration range of 550 to 600 ppm. The mode of action of extract (350 ppm) was examined in the case of Aspergillus niger van Tieghem. Distinct morphological changes were observed in treated hyphae in comparison to control . The treatment clearly showed anomalies in the hyphae; cell wall of became flaccid, cytoplasm started leaving the cell wall and became granulated.
