Key Highlights

  • Kills over 175 weeds.
  • Safe for pets and children.
Main Highlights
  • FAST ACTING WEED KILLER SPRAY WITH ACETIC ACID – This ready‑to‑use weed killer 5L contains 60g/l acetic acid for rapid contact action. Spray directly onto foliage of common garden weeds and moss – results become visible within 4 hours and full control within 24 hours. No mixing required: simply shake, attach a sprayer, and apply on a dry day when no rain is expected for at least 6 hours.
  • IDEAL PATIO WEED KILLER, PATH WEED KILLER & DRIVEWAY WEED KILLER – Perfect for use on block paving, gravel, paths and drives, and other unplanted areas around buildings. This weedkiller for paths and drives effectively controls moss and weeds in cracks and crevices. DO NOT USE ON LAWNS, vegetables, flowers, or shrubs – keep spray away from desirable plants.
  • EASY APPLICATION WITH A WEED KILLER SPRAY PUMP – For best results, use with any weed killer pump or suitable sprayer. Shake well before opening. Spray foliage evenly until fully wetted (no more than 100ml/m²). After use, turn nozzle OFF. Surfaces may become slippery temporarily – keep people and pets off treated areas until spray has dried (approximately 15‑20 minutes).
  • COVERS 50m² – CONTACT WEED KILLER – RE‑TREATMENT MAY BE NEEDED – One 5L bottle covers up to 50m². Because this is a contact weed killer, plant roots are not killed; re‑treatment will usually be necessary, especially for perennial weeds. Maximum 6 applications per year with at least 7 days between treatments. This product is for amateur use only. Store upright, away from children and pets, and protect from frost.
  • ACETIC ACID CONTACT WEED KILLER – AMATEUR USE ONLY – JOVS Weed Killer contains 60g/L acetic acid as a ready-to-use formulation. This non-selective contact weed killer controls common garden weeds and moss on areas not intended to bear vegetation. There are no residual effects in the soil. Always read the label carefully before use. Dispose of empty containers at a household recycling centre as hazardous waste. MAPP 21568. For amateur use only.
