Other claims from this paper (19)
- Intervention effect Preplant or preemergence 2,4-D caused up to 4% injury in adzuki bean.
- Intervention effect Preplant or preemergence 2,4-D caused up to 6% injury in kidney bean.
- Intervention effect Preplant or preemergence 2,4-D caused up to 7% injury in small red bean.
- Intervention effect Preplant or preemergence 2,4-D caused up to 8% injury in navy bean.
- Association Bean injury increased as the preplant interval shortened.
- Intervention effect At 1 WAE, 1056 g·ai·ha-1 2,4-D applied 14 days preplant caused up to 6% injury.
- Intervention effect At 1 WAE, 2,4-D applied 7 days preplant caused up to 10% injury.
- Intervention effect At 1 WAE, 2,4-D applied 1 day preplant caused up to 18% injury.
- Intervention effect At 1 WAE, postseeding 2,4-D caused up to 5% injury.
- Intervention effect One-day preplant 2X-rate 2,4-D decreased bean stand by 13%.
- Intervention effect Other application timings had stand counts similar to untreated control.
- Intervention effect The 528 g·ai·ha-1 preplant rate reduced bean dry weight by up to 23%.
- Intervention effect The 1056 g·ai·ha-1 preplant rate reduced bean dry weight by up to 43%.
- Intervention effect One-day preplant 1056 g·ai·ha-1 2,4-D decreased bean height by 10%.
- Intervention effect Other 2,4-D timings did not affect bean height.
- Intervention effect 2,4-D treatments had no reported effect on bean maturity or yield.
- Recommendation The authors recommended 14-day preplant or preemergence application as safest.
- Intervention effect Injury was higher with 7- and 1-day preplant application.
- Observation Adzuki bean had less injury than kidney, small red and navy bean.
