  • Apply when weeds are actively growing
  • Apply follow -up treatments as required if sufficient new growth warrants treatment

Critical Comments
To maximise the performance of spray application.

  • Apply higher rates for dense weed conditions
  • If an adjuvant is not used poor weed control will occur
  • Do not apply after frosts have occurred
  • Irrigation or rainfall within 2 hours of application will reduce control
  • Do not mow for at least 2 days after treatment to ensure optimum control
  • Sempra may damage or delay establishment of newly seeded, sodded or sprigged turf that is not well established.
  • Sempra may damage or delay recovery of turf weakened by weather conditions or by physical damage such as scarification, coring, aeration or top dressing.

Withholding Period

  • Do not apply clippings from treated areas for mulch around fruit trees or vegetables
  • Do not feed treated grass clippings to poultry or other livestock
  • Do not allow grazing of treated turf.
