Summary
This summary is machine-generated.Ginkgo leaf litter and its extract effectively suppress potato common scab disease by reducing pathogen abundance and enhancing beneficial soil bacteria. These natural treatments restore soil health and boost plant defenses against soil-borne diseases.
Area Of Science
- Agricultural Science
- Soil Science
- Plant Pathology
Background
- Soil-borne diseases like potato common scab (PCS) are exacerbated by soil degradation.
- Effective, eco-friendly strategies are needed to manage soil diseases and restore soil health.
Purpose Of The Study
- To evaluate the efficacy of Ginkgo leaf litter (GL) and its extract (GE) in suppressing PCS.
- To elucidate the underlying mechanisms of disease suppression by GL and GE.
Main Methods
- Pot and field trials were conducted to assess disease suppression by GL and GE.
- Soil microbial community structure, pathogen abundance, and plant defense responses were analyzed.
- Key beneficial microbial strains were isolated and characterized.
Main Results
- GL and GE significantly reduced the PCS disease index, with GL achieving over 50% suppression.
- Treatments reduced pathogen abundance, altered soil bacterial community structure, and enhanced stochastic assembly processes.
- GE inhibited pathogen toxin gene expression and up-regulated plant defense genes.
Conclusions
- Ginkgo leaf litter is a promising soil amendment for suppressing potato common scab.
- Mechanisms involve pathogen antagonism, beneficial microbial enrichment, and enhanced plant defense.
- This approach offers a sustainable strategy for managing soil-borne diseases.
