About this product

The Roundup Fast Action Weedkiller Pump ‘N Go Spray – 5L offers a straightforward solution for tackling unwanted garden weeds. This ready-to-use formula contains glyphosate and is designed to quickly eliminate most common garden weeds, delivering visible results within one to two days. It’s ideal for homeowners and gardeners seeking an efficient way to manage their outdoor spaces.

This pump sprayer provides approximately 10 minutes of continuous spray when utilising the full 5 litre capacity. The design incorporates a one-touch trigger to minimise hand fatigue, alongside an extendable lance that allows you to reach borders and beds with ease. It’s easily refillable, simplifying maintenance.

The glyphosate formula degrades in the soil through micro-organism activity, ensuring leaves no harmful residues and allowing for replanting once dry. The product covers approximately 250-300 square metres per application. Please note that the date printed on the item is a production date, not an expiry date.

The 5 litre bottle comes with a weight of 5.8 kg. While convenient in its ready-to-use format and ability to deliver rapid results, the large volume can be bulky for storage between uses.
