A concentrate that kills the whole weed, roots and all, not just the top growth.

Glyphosate 360g per litre goes to work on grasses and weeds like couch, paspalum, winter grass, bamboo and lantana, taking the root system with it rather than leaving the plant to bounce back in a fortnight. It suits rockeries, garden beds, driveways, fence lines and lawn edges, and it's non-residual, so you can replant the treated ground after fourteen days.

Buying it as a concentrate means you're not paying for water. Mix 10mL per litre for general weeds or step up to 15mL per litre for woodier customers, and one litre makes up a serious volume of ready-to-use spray. Mix only what you need for the day and keep the rest sealed for next time.

Best results come from spraying while the weeds are actively growing, with no rain forecast for at least six hours after application. That gives it time to get in through the leaves before it gets washed off.

Full mixing rates and application notes are in the tabs below.
