- Slide 1
- Establishment and Seed Production of Native Forbs Used for
Restoration Jessica Wiese Montana State University Fabian Menalled,
Bruce Maxwell, James Jacobs, Susan Winslow
- Slide 2
- Why wildflower management? High value crop with very specific
management - $40-250 per lb, depending on species Importance of
ecological diversity - Seed mixes typically grasses - Open niche -
Ecological services of diversity
- Slide 3
- High demand for restoration and seed production National Parks
and severely disturbed sites
- Slide 4
- RestorationProduction
- Slide 5
- Factors affecting establishment Seed viability Seed germination
Source of seed Weed competition Herbicide response
- Slide 6
- Objectives Compare effects of pre- and post-emergence
herbicides on wildflower seedling establishment, injury, and seed
production Evaluate effects of each herbicide on weed control
Assess the economics of weed management

- Slide 9
- Greenhouse herbicide screening Identify pre- and post-emergent
herbicides that do not cause seedling damage
- Slide 10
- Pre-emergence screening 5 soil applied pre-emergent herbicide
Dacthal WP (DCPA), Spartan (sulfentrazone), Aatrex (atrazine),
Surflan (oryzalin), Treflan, (trifluralin) Randomized split-plot
with four replications Living seedlings per row, leaves formed per
seedling, height, dry weight
