Agriculture and Agri-Food Canada Biopesticide: Phoma macrostoma
Control of broadleaved weeds in turf, agriculture, and forestry

Agriculture and Agri-Food Canada is inviting Letters of Interest from companies working in the professional lawn and garden care, agriculture, horticulture, and forestry industries, to commercialize a patented biocontrol process for controlling dandelions and other broadleaved weeds. This technology has received conditional registration from the Pest Management Regulatory Agency in Canada and from the Environmental Protection Agency in the United States, and is in the final stages of receiving full registration in both countries. Descriptions of the technology are provided in Appendix A - Business Opportunity Document and the Fact Sheet.

This invitation for Letters of Interest will appeal to companies that specialize in R&D, distribution, and vertical integrated activities involved in the manufacture, distribution, and sales of pest control products.

As a first step in a process that will culminate in the award of a license for the technology, interested parties with a background in pest control, a strong performance record, and capacity in R&D are invited to submit a Letter of Interest.

  1. Phase One - Letters of Interest

    The Letter of Interest should include the information listed in Appendix B – Letter of Interest.

    Letters of Interest will be reviewed and up to five (5) candidate companies will be selected based upon their ability to demonstrate:

    • access to the requisite R&D expertise for further product enhancements;
    • experience in commercializing products in the areas of pest control; and
    • the benefit to Canada.

Appendix A - Business Opportunity Document

Agriculture and Agri-Food Canada (AAFC) has developed a patented bioherbicide to control dandelion and other broadleaved weeds. The bioherbicide received conditional registration from the Pest Management Regulatory Agency and the Environmental Protection Agency for use as a pre-emergent and a post-emergent on a broad spectrum of broadleaved weeds in established turfgrass, in new seeding of grasses, in field-grown nursery and ornamental plants and trees, and in container-grown ornamentals. AAFC has developed trade-secret protected fermentation and formulation technologies for application and delivery as a commercial product. AAFC is also developing a portfolio of data for future registration of the bioherbicide for use in agriculture.

The Challenge

Broadleaved weeds compete for light, nutrients, moisture, and physical space disrupting the uniformity, aesthetics, vigor and yield of turfgrasses, and agricultural and horticultural plants. Weeds are also a major source of pollen, which contribute to allergies and other irritations.

A healthy and vigorous plant stand provides numerous benefits ranging from cleaning our air by neutralizing pollutants and trapping dirt and dust, moderating temperature and noise levels, diminishing soil erosion, and creating a pleasing surrounding that contributes to our quality of life.

Legislation that limits herbicide-use in urban environments and development of herbicide–resistant weed populations in agriculture underscores the importance of developing alternative methods of weed control. Biological control provides a method that complements other tools used in integrated weed management systems.

The Solution

The indigenous fungus (Phoma macrostoma) was isolated from Canada thistle plants, but exhibits selective broadleaved weed control affecting other weeds such as dandelion, clover, wild mustard, ragweed, and others. There are no effects on grassy weeds (green foxtail and wild oats) or crops, such as wheat, barley, oat, millet, kamut, and grasses.

Phoma macrostoma can be used for broadleaved weed control in...

Urban Areas/Turfgrass



When applied before weed emergence, the fungus prevents weed establishment in turf for 1-3 months. Post-emergent applications result in susceptible plants turning white and subsequently dying. The fungus produces phytotoxins during its growth phase which are taken up by the susceptible plants. Weed control is obtained when a granular formulation of the fungus is applied to moderately moist soil when the air temperature is between 10–30°C. Trials have demonstrated up to 80–100% control of dandelion and wild mustard and 50-80% control of Canada thistle.

Phoma macrostoma has limited mobility in the soil because growth is primarily by mycelial fragments, thus staying mostly where placed. It is not very competitive with other soil mycoflora and its presence declines with time. One year after application, it is rarely detected in the soil and there are few carryover effects to non-target plants. Above 30°C, its growth is curtailed. Overall the fungus has minimal impact on the environment.

The Opportunity

AAFC has patents issued on this technology in 16 countries and 1 pending. AAFC has developed a solid state fermentation and formulation process at the pilot scale level. Based on this manufacturing process, conditional registrations were granted in Canada and the USA for use in nonfood situations. AAFC has acquired data to support a new feed and food registration. Commercial opportunities for use are in:

  • Pre- and post-emergent broadleaved weed control
  • Areas where new turfgrass is being established
  • Established turf to prevent new weed infestations
  • Established turf to remove weed infestations
  • Agro-forestry for tree seedling nurseries
  • Field and container-grown ornamental/ nursery plants
  • Agricultural forage grasses, cereals and grains, and established alfalfa

AAFC will provide a licensee with all relevant data and access to the inventors in order to support the transfer of know how to implement these inventions in the licensee’s business.

Interested parties are asked to submit an Expression of Interest to AAFC by September 15, 2014.
