Other claims from this paper (11)
- Intervention effect MCP and 2,4-D formulations controlled five weed species.
- Intervention effect MCP did not satisfactorily control Russian thistle and red-root pigweed.
- Intervention effect No treatment controlled wild buckwheat.
- Intervention effect Treatments controlled weeds more effectively at the seedling stage.
- Recommendation MCP was favored over 2,4-D for weed control and grain yield in oats and flax.
- Intervention effect Oats were significantly more tolerant to MCP, particularly at early growth stages.
- Intervention effect Flax tolerance favored MCP most at the later treatment date.
- Intervention effect 2,4-D esters caused plant deformities.
- Intervention effect 2,4-D esters lowered oat and flax yields.
- Intervention effect 2,4-D esters significantly delayed flax maturity.
- Intervention effect Barley yield was not adversely affected by treatments.
