ROUNDUP PRO BIACTIVE 450 glyphosate weedkiller is a total weed control which delivers all the performance benefits that have made RoundUp Pro Biactive the choice for professionals across the country. Its systemic formula attacks weeds at the root meaning they don't come back! 

In addition, it also contains 25% more glyphosate by volume than its predecessor Roundup Pro Biactive 360. This increase in glyphosate means that each 5l can of ROUNDUP PRO BIACTIVE 450 weed killer will treat a much greater area, helping to reduce cost and storage space without losing any performance. 

ROUNDUP PRO BIACTIVE 450 glyphosate weedkiller is so special because it has a unique bioactive formulation which improves retention, uptake and translocation; this allows more glyphosate to get to the weed's growing points, which helps to achieve the highest levels of performance and superior long term control over difficult perennial weeds. The Biactivators also increase reliability over a wide range of applications and in difficult or rainy weather conditions; with excellent rainfastness being achieved within just 6 hours and the herbicide quickly degrading in the soil soon after application.

How does Roundup Pro Biactive 450 Work?

Roundup Pro Biactive 450 works by breaking down the waxy surface of the leaf and entering the plant cells. Most other Glyphosate weedkillers do this using a combination of the Glyphosate and Tallow Amine which is product which aggressively strips off the wax of the leaf allowing the Glyphosate to enter. Roundup Pro Biactive 450 contains the unique Transforb technology which gently allows the glyphosate to enter the plant more efficiently increasing the chance of a permanent kill of the weed. The difference with Roundup Pro Biactive 450 using this Transforb technology is that it allows the glyphosate to enter the leave without the plant/weed knowing that it is under attack, allowing the Glyphosate to enter the roots and kill the weed for good.

Where can I use Roundup Pro Biactive 450?

Roundup Pro Biactive 450 can be used in any plant free areas. Remember that Roundup Pro Biactive 450 is so effective that any cross spray will potentially kill any plants the weedkiller comes into contact with, so use with care.  It can be used on open soil, grass edges, gravel and aggregate drives, sand enclosures, and on hard surfaces such as pavements and pavings.

Is Roundup Pro Biactive 450 Safe for The Environment?

Roundup Pro Biactive 450 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 pro Biactive 450 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.
