Roundup Weed Killer (Herbicide) 20L Canister – Glyphosate 360 g/L

Roundup Extra is a professional-grade, soluble concentrate (SL) herbicide formulated for the comprehensive control of annual and perennial grasses and broad-leaved weeds. Its systemic action, powered by a 360 g/L concentration of glyphosate, ensures effective translocation throughout the plant, from the point of foliar contact down to the root system, providing complete and long-lasting weed control.

Engineered for reliability and performance, Roundup Extra is a critical tool for land management in agricultural, industrial, and non-cropland settings.

Mode of Action

Upon application, Roundup Extra is absorbed by the foliage and other green parts of the weed. The active substance, glyphosate, is then translocated systemically throughout the plant, including to underground roots, rhizomes, and stolons. Glyphosate works by inhibiting the EPSPS enzyme, which is essential for the synthesis of specific amino acids vital for plant growth. This targeted metabolic disruption leads to a cessation of growth, followed by chlorosis, necrosis, and eventual death of the entire plant, preventing regrowth.

Key Technical Attributes

• Active Substance: 360 g/L Glyphosate, formulated as a potassium salt for enhanced uptake.

• Systemic Efficacy: Ensures complete translocation to the root system for effective control of deep-rooted perennial weeds (e.g., Cirsium arvense, Elymus repens).

• Broad-Spectrum Efficacy: Provides reliable control over a wide range of monocotyledonous and dicotyledonous weeds.

• Superior Rainfastness: Advanced surfactant technology ensures rapid foliar uptake, becoming rainfast within a few hours of application, thus securing the treatment's effectiveness in variable weather conditions.

• High-Concentration Formula: The 20-litre packaging is designed for large-scale applications, offering an efficient and cost-effective solution for professional operators.

• Flexible Application: No residual soil activity, allowing for drilling or planting of subsequent crops following the recommended cultivation interval.

Primary Areas of Application

Roundup Extra is recommended for use in the following professional scenarios:

• Agriculture: Pre-harvest application in cereals and oilseed rape; stale seedbed preparation; post-harvest stubble management.

• Non-Cropland: Total vegetation control on industrial sites, railway lines, roadsides, and hard surfaces (non-permeable).

• Forestry: Weed control in pre-planting and site preparation.

• Amenity & Landscaping: Management of vegetation on land temporarily removed from production.

Guidance for Professional Use

• Application Method: Apply with a calibrated boom sprayer or knapsack sprayer equipped to produce a medium-to-coarse spray quality to minimize drift.

• Timing: For best results, apply when weeds are actively growing and have sufficient leaf area to absorb the spray. Avoid application during periods of drought, frost, or when rainfall is imminent.

• Dilution & Rate: Consult the product label for specific dose rates corresponding to the target weed species and growth stage. Always use clean water for dilution.

• Post-Application: A cultivation interval of at least 7 days is recommended for perennial weeds to allow for complete translocation of the active ingredient to the root system.
