Description
CONCUSSION 540 Glyphosate Herbicide is a strong weed killer designed for large areas like gardens, farms, lawns, and industrial spaces. It contains 540g/L of glyphosate (as potassium salt), which works by soaking into weeds and killing them down to the roots. This helps stop weeds from coming back and keeps your plants healthy.
You can use it in both home and commercial settings. It works fast on many tough weeds like bindweed, clover, nettles, and dandelions. The potassium salt formula breaks down quickly in the environment, making it safer for planting after use.
CONCUSSION 540 comes in 1L, 5L, and 20L bottles to fit different needs. Its concentrated formula covers a lot of ground, saving you money and time. Clear instructions make it easy to use, even if you’re new to herbicides.
Stop weeds from damaging your crops or garden with CONCUSSION 540. Buy it today for strong, reliable weed control.

Tips for use
Mixing Instructions:
Fill the spray tank 1/3 to ½ full with clean water and start stirring.
Add 800 g of ammonium sulfate per 100 L of spray solution (if recommended) and mix.
Add other required additives or pesticides, then add the herbicide and the rest of the water.
Add surfactant (if needed) near the end to minimize foam.
Keep stirring while spraying and use the mixture promptly.
Clean all equipment thoroughly after use.
Application Tips:
Treat weeds with at least one true leaf (broadleaf) or two leaves (grasses).
Avoid spraying weeds under stress from drought, frost, or damage.
Allow weeds to regrow to 6–8 cm after heavy grazing before spraying.
Avoid disturbing weeds (e.g., grazing or tilling) for at least 6 hours (annual weeds) or 7 days (perennial weeds) after spraying.
Important Notes
Rain: If it rains within an hour of application and causes runoff, re-treatment may be needed. Add “Wetter TX” to improve rain resistance on winter weeds.
Grazing: No waiting period is required, but delay grazing to ensure the herbicide fully absorbs. Some weeds may become toxic to livestock after spraying—wait for them to brown completely before grazing.
Storage:
Store in a cool, ventilated place out of direct sunlight.
Keep away from food, seed, or feed.
Safety Guidelines
Avoid contact with skin, eyes, or clothing.
Wear protective gear: gloves, goggles, and overalls when handling or spraying.
If in eyes, rinse with water immediately.
Wash hands, clothing, and equipment after use.
First Aid
If poisoning occurs, call a doctor or Poisons Information Centre (Australia: 13 11 26). Refer to the Safety Data Sheet (SDS) for detailed safety advice.
