- Intervention effect Tarping reduced early broadleaf weed emergence compared with nontarped beds.
- Intervention effect Two herbicide applications gave greater weed control than one without hand-weeding.
- Intervention effect With hand-weeding, one and two herbicide applications produced similar end-of-season weed biomass.
- Intervention effect With hand-weeding, one and two herbicide applications produced similar onion yield.
- Intervention effect Tarping with herbicides and hand-weeding provided long-term weed control and maintained onion yield potential.
