Agricultural technology firms including Spornado, BioScout, and Paramoria AgriScience deployed airborne spore detectors in 2026 to track pathogen movement. These systems can identify threats up to two weeks before visual plant symptoms emerge, though standardized action thresholds remain an industry challenge.
Why it matters
Early detection allows farmers to optimize the timing of fungicide applications, potentially reducing unnecessary chemical use and preventing yield loss. The industry is currently struggling to translate raw spore counts into clear, actionable spray-or-don't-spray guidance for broad-acre management.
Current molecular testing covers approximately 35 distinct pathogens across 18 crops, with Spornado using DNA analysis and BioScout utilizing computer vision to identify airborne spores. While researchers can detect fungal presence early, they lack a definitive correlation between detected spore quantities and crop-level economic damage.
The players
Spornado
A Toronto-based diagnostic firm that provides molecular testing services for agricultural pathogens.
BioScout
An ag-tech company focused on automated, AI-driven identification of airborne biological threats.
Paramoria AgriScience
A Lethbridge-based developer of specialized sampling hardware designed for broad-acre farming operations.
The details
Spornado utilizes airborne samplers to capture material on cassettes, which are then transported for DNA analysis at partner laboratories to confirm pathogen presence. BioScout employs an automated imaging system that uses artificial intelligence—software capable of identifying patterns in large data sets—to classify spores captured in the field. Both approaches aim to identify fungal threats before the pathogen induces visual crop stress.
Timeline
BioScout field tested its automated imaging technology in Manitoba in 2026.
Spornado expects to provide direct spray guidance by the 2027 growing season.
The Tech Race
The transition from traditional visual scouting to molecular diagnostics follows a broader trend of digitizing field-level biology. Developers are now competing to establish the first widely accepted economic threshold for pathogen counts, which will define the efficacy of these new monitoring tools.
Farmers and agricultural managers may eventually use these tools to refine their fungicide treatment schedules based on real-time molecular data. Widespread adoption currently hinges on the development of reliable economic thresholds to guide decision-making during the growing season.
The takeaway
The move toward molecular pathogen monitoring promises to move farmers from reactive spraying to evidence-based intervention. Observers should watch for the 2027 growing season to see if companies can successfully formalize economic spray thresholds based on these spore counts.
What happens next
Spornado plans to introduce direct spray-or-don't-spray guidance for farmers starting in the 2027 growing season.
