- Intervention effect Pyraflufen-ethyl at 6.7 and 13.4 g ai ha-1 caused less than 2% injury in azuki, kidney, small red and white bean.
- Intervention effect 2,4-D ester at 520.3 and 1040.6 g ai ha-1 caused up to 4 and 6% injury in azuki bean.
- Intervention effect 2,4-D ester at 520.3 and 1040.6 g ai ha-1 caused up to 5 and 12% injury in kidney bean.
- Intervention effect 2,4-D ester at 520.3 and 1040.6 g ai ha-1 caused up to 7 and 12% injury in small red bean.
- Intervention effect 2,4-D ester at 520.3 and 1040.6 g ai ha-1 caused up to 5 and 8% injury in white bean.
- Intervention effect Pyraflufen-ethyl/2,4-D ester at 527 and 1054 g ai ha-1 caused up to 4 and 6% injury in azuki bean.
- Intervention effect Pyraflufen-ethyl/2,4-D ester at 527 and 1054 g ai ha-1 caused 5 and 11% injury in kidney bean.
- Intervention effect Pyraflufen-ethyl/2,4-D ester at 527 and 1054 g ai ha-1 caused 7 and 13% injury in small red bean.
- Intervention effect Pyraflufen-ethyl/2,4-D ester at 527 and 1054 g ai ha-1 caused 5 and 10% injury in white bean.
- Intervention effect Preplant pyraflufen-ethyl, 2,4-D ester or their combination had no adverse effect on dry bean stand, aboveground dry biomass or height (apart from the 2X-rate exceptions).
- Intervention effect Preplant pyraflufen-ethyl, 2,4-D ester or their combination had no adverse effect on dry bean seed moisture content or yield.
- Intervention effect 2,4-D at the 2X rate and pyraflufen-ethyl/2,4-D ester at the 2X rate reduced dry bean plant height by up to 28%.
- Recommendation The authors conclude that preplant pyraflufen-ethyl (6.7 g ai ha-1), 2,4-D ester (520.3 g ai ha-1) and pyraflufen-ethyl/2,4-D ester (527 g ai ha-1) are safe for weed management in azuki, kidney, small red and white bean.
- Recommendation The authors advise care to avoid spray overlaps with 2,4-D ester and pyraflufen-ethyl/2,4-D ester to avoid unacceptable dry bean injury.
