  • Application Timing
    • Apply as a broadcast spray, with a recommended surfactant, to potatoes prior to initiation of flowering
    • Recommended non-ionic surfactant: Citowett Plus, Agral 90 or Ag-Surf at 2 L per 1000 L spray solution (0.2% v/v)
    • Application to control annual grasses and quackgrass must be made before the crop canopy can interfere with spray coverage of the target weeds. Cultivation is NOT recommended within 7-10 days prior to or after application.

    Weeds which emerge after application of Prism™ SG herbicide will not be controlled. Application should be made when the majority of weeds have emerged. Annual grass and broadleaf weeds are most sensitive when small and actively growing. Early crop establishment and a good crop stand are important in providing competition for weeds and effective post-emergence control of quackgrass  and annual weeds when using Prism™ SG.

    Rainfast: 4 hours
