英文摘要 | Globally, Fusarium root rot, which is caused by Fusarium graminearum, reduces wheat (Triticum aestivum L.) yield and quality up to 20%. Colonization of roots by F. graminearum has been recognized, but controlling Fusarium root rot using worm extracts (mucus, vermicompost tea, and vermiwash) has received little attention. We report the antagonistic properties of redworm (Eisenia fetida) extracts against F. graminearum and their effects on wheat seedling growth. Mycelial growth inhibition against the fungus was conducted in quintuplicate using the extracts in vitro. The extracts significantly inhibited mycelial growth of the fungus under in vitro conditions, and there was significant interaction between the infections and extracts for all the parameters measured (root and shoot lengths, root biomass, and disease index). Redworm mucus and 14-d vermiwash produced moderately (26%) to relatively less (16%) antifungal activity, respectively. Vermiwash and augmented vermicompost tea were able to inhibit Fusarium root rot and improve (>58%) the growth of the inoculated seedlings under laboratory conditions. Vermiwash also acted as nutritional supplement, enhancing plant growth. The extracts suppressed F. graminearum and could serve as a potential bio-fungicide in the integrated management of Fusarium root rot in wheat. Longer term experiments under field conditions are needed to validate the findings from the current study. |
