Overview
Roundup® Pro Biactive TM herbicide is an aqueous solution containing 360 g/l
glyphosate. It is a herbicide which is taken up by foliage and translocated to root systems.
Roundup® Pro Biactive TM is recommended for control of Annual and Perennial
grasses and Broad-leaved weeds in non-crop areas such as roadsides, paths, hard surfaces
and along fences and walls. It is recommended for cleaning up weedy ground prior to
planting or sowing, for total weed control on industrial sites and for aquatic weed control.
Roundup® Pro Biactive TM herbicide may also be used as a directed spray in
ornamental plantings, and in forestry for site preparation and post planting treatments.
Weeds controlled and application timing
weeds. It is important that all weeds are at the correct growth stage when treated,
otherwise some regrowth may occur and this will need re-treatment.
Apply Roundup® Pro Biactive TM herbicide where there is full emergence of grasses
and Broad-leaved weeds and they have ACTIVELY GROWING green leaves. All weeds
should be treated before growth slows down or stops in the autumn.

 Roundup® Pro Biactive TM herbicide controls most emerged grasses and Broad-leaved
This product will not give an acceptable control of Horsetails (Equisetum arvense) - repeat
treatment will be necessary.
Note: the effects of treatment on the long term control of perennial Broad-leaved weeds
has not been investigated.
Symptoms on the weeds
Symptoms of treatment are generally first seen 7-10 days, or longer (if growth is slow),
after spraying. These take the form of leaf reddening followed by yellowing and are usually
quicker to appear on grasses than on broad-leaved weeds. Reaction of nettles is slow.
Important: To obtain optimum weed control, weeds must be left undisturbed with no
further treatment or cultivation for 7 days after application. Allow 2-3 weeks for
symptoms to develop then re-treat any unaffected plants using spot treatments.
Effects of weather
A period without rain of at least 6 hours, and preferably 24 hours, must follow application
of Roundup® Pro Biactive TM herbicide.
Do not spray in windy conditions as drift onto desired plants or crops could severely
damage or destroy them.
Do not spray on to weeds suffering from drought, waterlogging, heat or frost, otherwise
poor control may result.
