How it Works
Absorbed through leaves. Sharply inhibits rate of assimilation of CO
2
in treated plants within 6 hours. Resistant
species (sugar beets) begin recovery in this time while susceptible species do not.
Expected Results
Under warm conditions, weed kill is complete in 4 - 7 days. Cool conditions require longer periods of up to 2 weeks.
Restrictions
Rainfall:
Rainfall within 6 hours of application may reduce weed kill.
Grazing:
Do not graze treated crops or use for livestock feed; sufficient data are not available to support such use.
Pre-harvest Interval:
Do not apply to sugar beet later than 60 days prior to harvest.
Recropping
:
Recropping restrictions not specified on the label.
