Other claims from this paper (7)
- Intervention effect Total weed control ranged from 0% with no acetic acid to 74% with 20% acetic acid at 935 L/ha plus canola oil.
- Intervention effect Optimum total grass and crabgrass control occurred with 20% acetic acid at 935 L/ha, giving 44% to 63% control.
- Intervention effect Broadleaf weed control was 84% or greater with either 10% acetic acid at 935 L/ha or 20% acetic acid at 187 or 935 L/ha.
- Intervention effect 5% acetic acid at 187 L/ha gave good control (77% to 90%) of cutleaf evening primrose.
- Intervention effect Averaged across volumes and adjuvants, weed control increased for all species as acetic acid concentration rose from 5% to 20%.
- Intervention effect Averaged across concentrations and adjuvants, weed control increased as application volume rose from 187 to 935 L/ha.
- Intervention effect Adding orange oil or canola oil to vinegar sprays gave little or no advantage.
