Roundup® Super Concentrate Grass & Weed Killer is a non-selective, systemic herbicide designed to control unwanted weeds and grass on hard surfaces and landscape areas, delivering visible symptoms within 3 days and complete control in 2 - 4 weeks. Ideal for large affected areas, it kills to the root using glyphosate, which is absorbed through the leaves and transported to the roots to disrupt essential plant processes.
To use, mix 50 mL with 2.5 L of water (1 part product to 50 parts water) and apply evenly with a tank sprayer over approximately 50 m² (538 ft²), ensuring thorough coverage without runoff. This 1 L super concentrate makes up to 51 L of usable solution and can treat up to 1000 m² (10,764 ft²). Rainproof in 2 hours, it is best applied when weeds are actively growing in calm conditions to avoid drift onto desirable plants.
