Mustgrow's TerraMG shows Clubroot suppression in trial

MGRO · Price
Executive Summary
- Mustgrow Biologics Corp. released results from a two-year field trial program (2024-2025) on approximately 100 acres of canola in the Canadian Prairies, demonstrating that its proprietary biocontrol product, TerraMG, effectively suppresses clubroot disease and improves yields.
- The trials showed significant reductions in clubroot resting spore concentrations and root gall severity, with yield benefits varying based on disease pressure and weather conditions.
- TerraMG is currently undergoing registration with Health Canada's Pest Management Regulatory Agency as an organic biocontrol solution for clubroot, a disease for which no effective registered products currently exist.
Key Details
- Product: TerraMG, an organic biocontrol product derived from mustard seed meal that releases isothiocyanates to suppress soil-borne pathogens.
- Trial Scope: Two-year program (2024 and 2025) conducted on ~100 acres in the Canadian Prairies via wholly-owned subsidiary NexusBioAg.
- 2024 Results (Wet Season/High Disease Pressure):
- Up to 95% reduction in clubroot spores compared to untreated controls.
- Yield increase of up to 7 bushels per acre (19% increase over the 2024 Canadian average of 36 bushels/acre).
- Estimated value increase of $91 per acre for farmers (based on ~$13/bushel commodity price).
- 2025 Results (Dry Season/Lower Disease Pressure):
- Yield increase of 1 to 2 bushels per acre over the control.
- Reduced impact compared to 2024 due to lower clubroot prevalence in drier conditions.
- Mechanism of Action: Releases naturally occurring isothiocyanates with fungicidal and biocidal activity to suppress clubroot (Plasmodiophora brassicae) and other soil-borne pathogens.
- Regulatory Status: Actively working toward registration with Health Canada's Pest Management Regulatory Agency.
- Market Context: Clubroot causes devastating losses (up to 100% in early infection) and no effective registered products currently exist for suppression; current management relies on sanitation, crop rotation, and genetically resistant varieties which are becoming less effective against mutated pathotypes.
- Company Portfolio: Mustgrow holds approximately 110 issued and pending patents and distributes third-party crop nutrition solutions alongside its proprietary products.
Notable Quotes
- "Field trial findings have demonstrated Mustgrow's TerraMG is a sustainable technology capable of suppressing clubroot parasitic disease (P. brassicae) and promoting higher canola yields and root systems under various disease pressures."
- "In 2024, Clubroot spores were more prevalent due to a wetter growing season and TerraMG performed exceptionally well with up to 95-per-cent reductions in Clubroot spores."
- "A biological, soil-active technology, like MustGrow's TerraMG, capable of reducing resting spore loads, could represent a significant breakthrough in sustainable Clubroot management for Canadian farmers."
