Tested where nematodes are a real problem
Led by FMC Technical Services Manager, Hugh Armstrong, the Catulia® large trial program has focused on evaluating performance under real-world conditions where root-knot nematodes are known to significantly impact marketable yield and profitability.
Across Australia, Catulia® has been evaluated in high-pressure environments across crops including carrots, sweet potato, tomato and cucurbits.
KEY OUTCOMES
- Excellent protection from damage caused by Root-Knot nematodes, comparable to synthetic standards.
- Greater flexibility of use.
- Easy to integrate in crop protection programs
Trials have been deliberately conducted in sites with known nematode pressure to reflect real-world growing conditions and ensure results are relevant to commercial production systems.

Biological protection, built around the root system
Dr. Sylwia Fudali-Alves, a nematologist who has worked on the development of Catulia® for more than a decade, provides insight into the science behind the technology.
Catulia® combines two Bacillus strains designed to establish early in the root zone and protect plants where they are most vulnerable.
KEY MECHANISMS OF CATULIA®
- Early root colonisation
- Formation of a protective biofilm
- Activate plant defence genes, even in untreated roots
crop benefits observed
- Stronger root systems and better plant establishment
- Improved nutrient and water uptake
- Greater tolerance to nematode pressure
Timing remains critical, with early application soon after planting or transplanting, supporting effective root colonisation and consistent performance.

Designed to support integrated nematode management, Catulia®
- Complements existing crop protection programs
- No residue or plant-back restrictions expected
- Flexible application timing and methods
- Supports long-term resistance management.
What's next
Catulia® is currently undergoing APVMA evaluation for registration in Australia, with ongoing local trials continuing to build trial data across vegetable production systems across a range of geographies.
