When to Use

Resolva Xtra Tough Weedkiller contains glyphosate as a ready to use spray for effective control of annual and deep-rooted perennial garden weeds, including grasses, docks, nettles, dandelion, bindweed and many more. Resolva Xtra Tough Weedkiller is broken down naturally in the soil to leave no residues

  • Use on a calm day from February until September when weeds are actively growing and have a large leaf area to absorb the weed killer spray
  • Perennial weeds will be controlled best between June and August
  • Rainfall within 6 hours of application may reduce effectiveness and require re-treatment
  • Resolva Xtra Tough Weedkiller kills most weeds with a single application. Some tough weeds may need a repeat treatment if regrowth appears

Where to Use

  • Spray the weed leaves lightly until fully wetted but avoid run off
  • Rotate spray adjuster to ‘X’ position after use and before storage
  • Do not walk into treated areas until the spray has dried on the leaves to avoid transfer to lawns and other vegetation
