Other claims from this paper (7)
- Intervention effect Adding ammonium sulfate to imazethapyr plus nonionic surfactant increased quackgrass control, especially at low imazethapyr rates.
- Intervention effect Imazethapyr applied with nonionic surfactant plus ammonium sulfate was absorbed by quackgrass leaves about twice as much as with nonionic surfactant alone in the greenhouse.
- Observation Imazethapyr absorption by maize BMS cells was diffusion-mediated and energy-dependent.
- Observation Imazethapyr absorption by maize BMS cells had a pH optimum of approximately 3.
- Association The equilibrium concentration of imazethapyr in maize BMS cells was a linear function of the external concentration.
- Association The ability of ammonium sulfate to promote medium acidification was linearly correlated with imazethapyr uptake by maize BMS cells.
- Mechanism The ammonium sulfate-induced stimulation of imazethapyr absorption in maize BMS cells depends on ATP production and plasma membrane ATPase function.
