Identification and Reproduction

Identification:

  • Spring milletgrass is an annual grass that grows up to 90 cm tall. 
  • Leaves connect directly the the stem and will point to a tip. 
  • It produces smooth, glossy florets that are diamond-shaped. 
  • Florets are straw yellow and will mature to a brown colour. The surface of the floret is covered in brown streaks. 

Reproduction:

  • This grass produces by seed. Seeds are easy transported by wind and can travel with other seed crops unintentionally. 

Habitat & Ecology

  • This grass commonly takes over cultivated fields, rangelands and pastures. 
  • It prefers soils that remain moist, especially in the winter months. 
  • Currently has not been found in Canada. It has been introduced to Idaho. 

Impacts

Social: 

  • Contaminant of winter wheat crops. 
  • Degrades pastures and reduces crop yields. 

Management

Prevention is a high priority for this plant. 

  • Use clean, high-quality seed mixtures that are certified.
  • Avoid transporting unknown soil or plant material.  
  • Ensure that equipment, vehicles and tools are clean and free of debris.  
  • Contact your local Canadian Food Inspection Agency (CFIA) if you think you have seen this plant.
