1 Use the higher rate for extended residual control or when heavier weed populations are present.

2 Including Group 2 resistant biotypes.

3 Some plants that germinate deeper in the soil and emerge late may escape treatment. Heavy infestations of this weed species may only be suppressed.

4 Tank mixing is recommended for fields with a history of heavy infestations of this weed species.

5 Some plants that germinate deeper in the soil and emerge late may escape treatment.

Application Tips

Restricted entry interval – 12 hours

  • Minimum seed depth is 4 cm.
  • For residual activity of labeled weeds, Zidua Prime must be applied and activated by moisture prior to weed seedling emergence.
  • Do not use on peat or muck soils with 7% or more organic matter content.

 

Pre-harvest interval

100 days 6
