When to use:


Although Roundup ProActive can be sprayed at any time of the year when weeds are green and growing, it is best to employ a 2-3 spray cycle. First spray ideal in March-April, again in June/July and spray before die back in September/October. This is a broad overview of when to use Roundup ProActive and if you have a specific weed in mind, please contact us as spray times may be different depending on the type of weed.


How does Roundup ProActive Work?


Roundup ProActive works by breaking down the waxy surface of the leaf and entering the plant cells. Tallow Amine aggressively strips off the wax of the leaf allowing the Glyphosate to enter. The unique formulation between Glyphosate and Biactivators draws the maximum amount of Glyphosate into the plant. This process increases the chance of a permanent kill of the weed. 


Where can I Use Roundup ProActive?


  • Hard surfaces
  • Amenity vegetation
  • Enclosed waters
  • Natural surfaces (which should not bear vegetation)
  • Land immediately adjacent to aquatic areas and open waters

Approved for use in areas open to the public/animals and near water.

Remember that Roundup ProActive is so effective that any cross spray will potentially kill any plants the weedkiller comes into contact with, so use with care. 


Is Roundup ProActive Safe for the Environment?


Roundup ProActive has a low toxicity to humans, animals, birds, fish and insects. The active ingredient acts on an enzyme that is actually found in plants which prevents the plant from making proteins. There is no need to segregate spraying areas and Roundup ProActive is approved for use in aquatic areas, which means in water or on land close to water. The world Health Organisation actually rates Glyphosate as ‘Practically non toxic’ which is the lowest classification available.

Can I keep and store diluted herbicide spray?

Once diluted the active ingredient will start to break down and lose activity within a few days. Ideally, surplus spray should be sprayed out onto an untreated area where it will have a beneficial herbicidal effect, but not on tarmac or concrete.
