Fusarium pressure is rising across cereal-growing regions. Looking for ways to protect cereals before symptoms even appear?
Fusarium diseases belong among the most challenging threats in cereal production. They reduce yield, compromise grain quality, and introduce mycotoxin risks that affect the entire food chain. Despite decades of chemical control, Fusarium keeps adapting – especially under fluctuating weather conditions and increasing regulatory pressure.
At BIOGAMA, we don’t just offer an “alternative” to chemicals; we provide a technological shift proven on over 30 million hectares worldwide. We approach Fusarium as a systemic issue that starts long before the ear appears. Our data from intensive field trials in Zubří (2021–2022) confirms that our biological shield matches the performance of high-end synthetic standards, while delivering a clean, residue-free harvest. In spring barley trials across the Czech Republic, we’ve demonstrated yield increases of up to 18% compared to untreated controls, effectively filling the “protection gap” left by the disappearance of traditional active substances like Mancozeb or Prochloraz.
Why Fusarium Is So Difficult to Control
Fusarium species are widespread soil inhabitants and don’t need an invitation. They survive on crop residues, colonize roots and crowns, and infect cereals at multiple growth stages – from early root development to flowering.
Traditional fungicide strategies focus mainly on foliar applications during heading. While these treatments can reduce visible symptoms, they often come too late to address the initial stages of infection occurring below ground.
Fusarium infections often begin in the soil and root zone – long before symptoms appear on ears or grain.
That’s the gap biology is built to close. Effective Fusarium management has to start where the infection does. At the level of roots and soil biology, not just the canopy.
The Role of Soil Biology in Fusarium Suppression
Healthy soils host complex microbial communities that naturally limit pathogen development. When this balance is disrupted – by intensive tillage, monoculture, or chemical pressure – Fusarium gains a competitive advantage.
Biological plant protection supports this natural balance instead of overriding it.
Products developed by Biogama, based on Pythium oligandrum, work directly in the rhizosphere. Once applied, the microorganism colonizes the root zone and interacts with both pathogens and the plant itself.
Its effects include:
- direct mycoparasitism of pathogenic fungi,
- stimulation of plant defense responses,
- protection of young roots and crowns.
In practice, this systemic protection provides the one thing every agronomist craves: yield stability. While synthetic molecules provide a temporary, static screen, our active predator establishes a living barrier that adapts to the season. In high-moisture “wet” years – when Fusarium pressure typically explodes – our technology is actually at its most aggressive because Pythium oligandrum requires humidity to activate its hunt.
From Seed to Root: Early Protection Matters
Fusarium control is most effective when it begins early. Seed and soil applications allow biological agents to establish themselves before pathogens dominate the root environment.
Biogama offers crop-specific biological solutions for cereals, including formulations suitable for:
- seed treatment (Polydresser),
- foliar application (Polyversum), with activity extending to the root zone.
By protecting roots during early growth stages, biological treatments help cereals develop stronger root systems and improved stress tolerance — creating less favorable conditions for Fusarium development later in the season.
More application examples can be found on our Field Crops page.
Biology as a Complement — Not a Replacement
Biological control does not aim to replace all chemical tools overnight. Instead, it provides an additional tool in farmer’s shrinking toolbox and reduces dependency on late, reactive interventions.
“Effective Fusarium control starts where the plant begins — in the soil and at the roots.”
Ing. arch. Martin Suchánek, Founder of Company
By integrating biological solutions into cereal protection programs, growers gain:
- earlier disease suppression,
- healthier root systems,
- more stable performance under variable conditions.
Towards More Resilient Cereal Systems
Fusarium management cannot rely on single interventions. It requires a shift from symptom control to system resilience.
Biological plant protection supports this shift by:
- protecting roots during early development and limiting pathogen establishment,
- supporting plant health throughout vegetation, including critical stages such as flowering,
- working with soil life rather than suppressing it,
- strengthening the plant’s own defense mechanisms.
At Biogama, we believe long-term cereal health begins below the surface – in the constant exchange between roots, biology, and soil. And that exchange has more to teach us every season than any single spray ever could.
