Microbiome-driven plant disease resistance enhancement technology

Overview

Cybiome GmbH is developing targeted microbiome enhancement strategies that boost plant disease resistance by selectively activating beneficial microorganisms already present in soil. The core premise is that healthy soils contain all the microorganisms needed for plant protection, but at densities too low to provide measurable benefits. By using specially designed prebiotic amendments that selectively boost these native beneficial bacteria, the technology enables improved plant growth and disease suppression without the need for pesticides or biocidal molecules.

This approach addresses a critical challenge in agriculture: managing aggressive pathogens such as Ralstonia solanacearum, which affects more than 200 crops globally. The solution offers a sustainable alternative to conventional chemical treatments, supporting environmentally responsible crop protection while maintaining yield quality.

Technical specifications

Key features:

• Predictive modeling platform that identifies which microbial species are essential for plant health
• Custom-designed prebiotic amendments that selectively activate native beneficial soil bacteria
• Integration of high-throughput DNA sequencing, bioinformatics analysis, and AI-driven predictive algorithms
• Compatibility with existing agricultural soils without introducing foreign biocontrol organisms
• Diagnostic reporting capabilities to assess soil microbiome composition and health
• Mathematical modeling tools for matching field data with in-silico simulations to optimize treatment selection

How it works:

The technology leverages the natural biodiversity already present in soil. Rather than introducing new microorganisms, the platform predicts which beneficial species are present at insufficient densities and identifies specific resources (prebiotics) that will selectively stimulate their growth. This targeted approach amplifies the native protective microbiome, creating a biological barrier against pathogens.

Technology readiness level

The technology has been validated through greenhouse experiments demonstrating a 90% reduction in disease intensity against Ralstonia solanacearum when soils were amended with predicted prebiotic resources. No biocidal molecules were used in these trials.

Next steps include field validation experiments lasting approximately four months to assess performance under real agricultural conditions, accounting for soil heterogeneity, climatic variation, and diverse microbiome compositions. Following field testing, the team will simulate optimal treatments for individual soils by combining field data with computational models. The technology is currently advancing from controlled-environment validation toward agricultural field deployment.
