Use Roundup ProActive for the control of annual and perennial grasses and broad leaved weeds
Roundup ProActive 5 litre controls weeds in non-crop areas such as roadsides, paths, hard surfaces and along fences and walls. Roundup ProActive is recommended for cleaning up weedy ground prior to planting or sowing, for total weed control on industrial sites and for aquatic weed control. It may also be used as a directed spray in ornamental plantings. Roundup ProActive controls annual grasses, perennial grasses and broad-leaved weeds.

Roundup ProActive contains two adjuvants, alone they offer excellent benefits but in combination they ensure an outstanding perfomance.
Retention, uptake and translocation are enhanced; so more glyphosate gets to the growing points providing superior long-term weed control. These Biactivators increase reliability over a vast range of applications and weather conditions, particularly rainfall.

Roundup ProActive has been specially formulated to offer an enhanced standard of operator safety. It is not a hazardous substance as defined by COSHH, when used in accordance with the label, and it does not carry a hazard symbol. In the environment, it provides up to 100 fold improvement in safety to some of the most sensitive animal species, when compared to older glyphosate formulations. Glyphosate, the active ingredient in Roundup ProActive, controls weeds by blocking the plant’s enzyme system. These enzymes, which are present in plants, do not occur in humans, animals, birds or fish. Hence, Roundup Pro Biactive is safe to everything except green plants.
