Milium vernale - Poaceae Family
- Flowers: Open panicles are green to purplish, and up to 8 inches long
- Seeds: Smooth and glossy, oval, 1.7mm to 2.0mm long. Brown streaks give the appearance of wood grain. Spring millet spreads only by seed.
- Leaves: Flat, ¼ inches wide and 4 inches long.
- Flowering Time: Stems each produce one cluster of flowers in the spring.
- Life cycle: Winter annual grass that grows up to 2 ½ feet tall, with drooping, upright or spreading stems. Seed heads appear in May, and seeds mature in June.
- A pest of winter wheat, Spring millet usually travels with the grain and gets planted with the crop. Once established it infests surrounding pastures.
- Native to Eurasia, Spring millet was found infesting winter wheat and other crops in north-central Idaho. Although there have been no other reported occurrences in North America, the infestation in Idaho is spreading rapidly.
Most effective control methods
- Little information or research currently exists on the control of Spring millet.
- According to several Idaho noxious weed control guidelines, spring tillage may control this plant.
- Currently no herbicides are labeled for its control.
