- Intervention effect Every tested 2, 4-D concentration at the 3-leaf stage was phytotoxic to wheat.
- Intervention effect Every tested 2, 4-D concentration at the 3-leaf stage was phytotoxic to barley.
- Intervention effect At 5-leaf, jointing and booting-to-heading, only 4000 and 8000 ppm caused phytotoxicity and lodging in wheat.
- Intervention effect At 5-leaf, jointing and booting-to-heading, only 4000 and 8000 ppm caused phytotoxicity and lodging in barley.
- Intervention effect All tested concentrations significantly reduced barley plant height.
- Intervention effect Concentrations of 1000 ppm and above significantly reduced wheat plant height.
- Intervention effect The 8000 ppm treatment at jointing and anthesis significantly reduced wheat grain yield.
- Intervention effect Barley grain yield fell significantly at 2000 to 8000 ppm applied at three specified growth stages.
- Intervention effect At the 5-leaf stage, 1000 ppm increased grain yield 18.7% versus the unweeded check.
- Intervention effect Higher 2, 4-D concentrations significantly reduced 1000-kernel weight and test weight in both crops.
- Intervention effect At 2000 to 8000 ppm at specified stages, 2, 4-D increased wheat and barley seed protein percentage.
- Intervention effect The same 2, 4-D treatments significantly reduced protein yield in both crops.
- Intervention effect 2, 4-D application had no significant effect on germination percentages in wheat and barley.
