When we talk about strong weed killers, we normally mean ‘total’, or ‘non-selective’ weed killers. In other words, a herbicide that will kill all vegetation that it comes into contact with. And when it comes to total weed killers, the strongest herbicide products available for most applications in the UK are those that contain glyphosate.

Generally speaking, the higher the amount of glyphosate, the stronger the weed killer will be. Glyphosate-based weed killers are commonly used to control weeds on hard surfaces such as roadsides and along fences and walls.

They are also ideal for removing weeds from ground prior to planting and sowing seeds.

On its own, glyphosate is not toxic to animals and humans, but it is used in different concentrations and mixes, so users must always read product labels carefully and follow manufacturer’s instructions. 

Which are the best glyphosate products?

We offer a range of glyphosate products here at Agrigem. Gallup Home and Garden Glyphosate is a popular herbicide used to control annual and perennial grasses and broad-leaved weeds in a variety of home settings. 

Planting can take place seven days after application, and it is rain fast in six hours. Gallup Home & Garden Glyphosate contains 360g/l glyphosate with one litre covering up to 2,500sqm.

Gallup Home & Garden 1L is the same formulation as professional use products, and approved for amateur use, but professional users in the amenity sector are more likely to purchase one of our professional-use products including:

Roundup ProActive 5L – controls a vast range of broad-leaved weeds 

Diamond Horsetail Weedkiller – glyphosate-based formulation specifically to tackle tough weeds like horsetail. A mix of two active ingredients (160g of 2,4-D per litre and 240g of glyphosate per litre), Diamond can penetrate the weed’s root system much quicker than products only containing glyphosate.

Gallup Biograde 360 – a non-hazardous formulation for control of all grasses and weeds. 

We stock a large number of other professional-use weedkillers containing glyphosate, each with a particular formulation for a variety of uses. Roundup Pro Vantage contains 480g/l glyphosate making it a popular product within the amenity sector for its reduced application rate. 

Generally speaking, the more concentrated glyphosate the product contains, the more powerful the product will be. Read more about industrial weedkillers in our guide, and find out more about glyphosate in our explainer blog here.
