Microbial consortium for enhanced turfgrass disease suppression
A synthetic microbial community (SynCom) designed to enhance turfgrass health by improving nutrient uptake, abiotic stress resilience, and disease suppression. This approach reduces reliance on irrigation and chemical inputs.
Overview
The proposed solution is a synthetic microbial consortium (SynCom) that consists of functionally distinct rhizosphere bacteria designed to enhance turfgrass health and management. By improving nutrient uptake and abiotic stress resilience, the SynCom offers dual benefits, including the enhancement of root growth and increased disease resistance. Unlike single-strain biological products, SynComs contribute diverse functional traits, making them more stable under variable environmental conditions. This innovative approach aims to not only elevate turf quality under heat and drought stress but also reduce dependence on irrigation and chemical inputs.
Technical specifications
Key features:
- Enhanced nutrient uptake: Improves nutrient availability and plant growth through root colonization and modulation of plant stress hormones.
- Abiotic stress resilience: Strengthens turfgrass against heat and drought stress by improving soil properties.
- Disease suppression: Provides direct antagonism against pathogens and promotes systemic resistance, reducing turfgrass disease prevalence.
- Delivery methods: Includes testing SynCom delivery via seed coat, soil inoculum, and foliar spray to determine the most effective method for turf establishment.
Core technologies:
- Utilizes well-characterized bacterial strains like Bacillus subtilis UD1022.
- Evaluates key bacterial traits such as EPS and surfactin for their roles in soil water retention and nutrient availability.
Technology readiness level
This technology has reached a Technology Readiness Level (TRL) of 6, indicating that it has been tested in relevant environments. Further validation includes controlled environment trials to assess the impact of SynCom on disease suppression and nutrient use efficiency, as well as mechanistic studies to explore the influence of bacterial traits on turfgrass resilience.
