Novel antimicrobial seed treatment for sudden death syndrome in soybeans
Quorum Bio introduces QB-04, a novel antimicrobial seed treatment that protects soybeans from sudden death syndrome. With multiple modes of action, QB-04 offers a reduced risk of resistance development. Currently at TRL 4, it is progressing towards soybean-specific formulation and efficacy testing.
Overview
Quorum Bio presents QB-04, a groundbreaking antimicrobial seed treatment designed to combat sudden death syndrome (SDS) in soybeans, caused by the pathogen Fusarium virguliforme. Unlike traditional fungicides, QB-04 operates through multiple modes of action, reducing the likelihood of resistance development. This innovative chemistry is both chemically and biologically characterized, leveraging soil microbes to deliver a robust and effective solution for crop protection.
Technical specifications
Key features:
- Novel Chemistry: QB-04 is a broad-spectrum, small molecule from soil microbes.
- Multi-Site Activity: Exhibits multiple, distinct modes of action not aligned with any single FRAC group.
- High Efficacy: Demonstrated strong inhibition of major plant pathogens, including Fusarium virguliforme.
- Prototype Formulation: Successfully formulated as a water-suspension concentrate for seed coating.
- Field Evaluation: Currently undergoing field trials against various pathogens to optimize performance.
Technology readiness level
QB-04 is at a Technology Readiness Level of 4, indicating that it is in the validation stage. Following successful in vitro assays and prototype formulation testing, the focus is on adapting the formulation for soybeans and conducting efficacy testing through greenhouse and field trials. These steps are crucial for transitioning QB-04 towards commercial readiness.
