Roundup ProActive weed killer is Recommended for the control of annual and perennial grasses and broad-leaved weed ( MAPP Number 17380 )

Roundup ProActive is recommended for control of annual and perennial grasses and broad-leaved weeds in non-crop areas, for cleaning up weedy ground prior to planting or sowing and for aquatic weed control. Roundup ProActive may also be used as a directed spray in ornamental plantings, orchards and for spot treating weeds in grassland. Roundup ProActive must be targeted only at weed growth on hard surfaces such as roadsides and paths,

A foliar applied translocated herbicide for the control of annual and perennial grass and broad-leaved weeds. For the control of emerged weeds in industrial and amenity situations, in forestry and in aquatic areas. Degraded by micro-organisms/microbes in the soil. The (COSHH) Control of Substances Hazardous to Health Regulations may apply to the use of this product at work. This product contains a soluble concentrate containing 360 g/l glyphosate, present as 441 g/l (35% ww) of the potassium salt of glyphosate.

Knapsack Application Rate estimator

A full 20 litre knapsack - applying spray at 250 litres/ha - will cover 800m2. Therefore, to apply Roundup at 4lt/ha, mix 320ml in 20 litres water. Therefore, to apply Roundup at 5lt/ha, mix 400ml in 20 litres water. Therefore, to apply Roundup at 6lt/ha, mix 480ml in 20 litres water.

Roundup ProActive is a patented potassium salt formulation containing 360gai/l glyphosate and a unique blend of two surfactants. The optimised blend of surfactants delivers highly efficient activity at the leaf surface and a synergistic improvement in glyphosate uptake and overall performance. Roundup ProActive incorporates a high technical specification and the formulation has been designed to address stewardship aspects, so vital now for glyphosate application.

How Roundup ProActive works

Roundup ProActive is a herbicide which is sprayed on to green leaves where it is absorbed and drawn into the plants vascular system. It then stops the production of the amino acids which build the protein the plant needs to grow and survive. The plant effectively starves to death.

Formulation Development

At Monsanto formulation scientists have a strong focus on the need for high level and consistent product performance whilst meeting the increasing demands of environmental stewardship and the practical use of glyphosate in the modern amenity situation. With this in mind, Roundup ProActive brings an advanced, clean label, formulation which not only incorporates leading technical specifications for glyphosate, but also addresses stewardship aspects so vital now for glyphosate application.

Roundup ProActive Formulation

Patented technology containing 360gai/l of the potassium salt and a unique blend of surfactants to deliver optimum efficacy and enhanced safety. The optimised blend of surfactants in Roundup ProActive provide the technology to aid transport across the leaf membrane and the formulation reduces surface tension so this highly active combination ensures a synergistic improvement in glyphosate uptake and overall performance. In addition the formulation retains the non-toxicity and biodegradability properties that are so important today and low viscosity is maintained through a wide range of storage and application conditions.


Roundup ProActive is one of Monsanto’s new generation of products developed with stewardship in mind.

  • Run-off is minimised by the rapid uptake which also enables the maximum use of weather windows, even in the more challenging situations.

  • Greater protection of operators and bystanders is afforded by the low drift properties of Roundup ProActive.

  • Safe for transport, handling and storage due to its non-hazardous status as defined by COSHH.

  • Can be used in areas open to the public and near water as its action blocks enzymes that are not found in humans, animals, birds or fish
