- Intervention effect At 1 kg/ha trifluralin in the soil, spring wheat dry matter production was reduced by 50% early in the season.
- Intervention effect As the season progressed, crop growth rates of wheat in trifluralin-treated plots exceeded those in untreated plots.
- Observation Maximum crop growth rates occurred between Zadok growth stages 30 and 45, where soil trifluralin was 0.3 to 0.5 kg ai/ha at seeding.
- Intervention effect Recovery from trifluralin injury was characterized by enhanced net assimilation rates, increased tillering and greater dry matter production per plant.
- Association Wheat seed yield was only weakly correlated with trifluralin levels in the soil at seeding.
- Intervention effect A linear regression model indicated that a 35% reduction in plant dry weight from trifluralin injury at the beginning of tillering would reduce seed yield by no more than 10%.
