DIRECTIONS FOR USE
USE IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.
Warnings
TAKE EXTREME CARE TO AVOID DRIFT.
DO NOT MIX, STORE OR APPLY ROUNDUP BIACTIVE IN GALVANISED OR UNLINED STEEL CONTAINERS OR SPRAY TANKS.
DO NOT leave spray mixtures in tank for long periods and make sure tanks are WELL VENTED.
Do not apply lime, fertiliser, farmyard ma nure and pesticides until 5 days after application of ROUNDUP BIACTIVE.
Restrictions
A period without rain of at least 6 hours and preferably 24 hours must follow application of Roundup Biactive.
Do not spray on weeds where growth is impaired by natural senescence, drought, high temperature, a covering of dust, flooding or severe/prolonged frost at, or immediately after application, otherwise poor control may result.
Do not spray in windy conditions as drift onto desired crops or vegetation can severely damage or destroy them.
Do not tank-mix ROUNDUP BIACTIVE with adjuvants, pesticides or fertilisers, except as specified in the Compatibility section.
Weeds controlled
Roundup Biactive herbicide controls most emerged grasses and broad-leaved weeds. It is important that all weeds are at the correct growth stage when treated, otherwise some re-growth may occur and this will need re-treatment. 2011 Page 5 Apply Roundup Biactive herbicide once grasses and broad-leaved weeds have emerged and they have ACTIVELY GROWING green leaves.
PERENNIAL GRASSES must have full emergence of healthy, green leaf. (Common Couch, for example, becomes susceptible at the onset of tillering and new rhizome growth, which usually occurs when plants have 4-5 leaves, each with 10- 15 cm of new growth).
PERENNIAL BROAD-LEAVED WEEDS are most susceptible around the flowering stage.
ANNUAL GRASSES AND BROAD-LEAVED WEEDS should have at least 5 cm of leaf, or 2 expanded true leaves, respectively. In set-aside, annual grasses are best treated at full ear emergence, or before stem elongation. Application during the stem extension phase of annual grasses e.g. Black-grass and Brome species on set-aside between the end of April and end of May, may result in poor control and require re-treatment.
BRACKEN should be treated after frond tips are unfurled, but pre-senescence.
OTHER SPECIES - recommendations for specific Areas of Use are given in the Recommendation Tables
Note: The effects of treatment on the long-term control of perennial broad-leaved weeds has not been investigated.

Weed resistance strategy
There is low risk for the development of weed resistance to Roundup Biactive. Strains of some annual weeds (e.g. Black-grass, Wild oats and Italian Ryegrass) have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. This should include integrating herbicides with a programme of cultural control measures. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer (Monsanto). Growers are encouraged to implement a weed resistance strategy based on (a) Good Agricultural Practices and (b) Good Plant Protection Practices by:
Following label recommendations
The adoption of complimentary weed control practices
Minimising the risk of spreading weed infestations
The implementation of good spraying practice to maintain effective weed control. Using the correct nozzles to maximise coverage
Application only under appropriate weather conditions

Upon soil adsorption the herbicidal properties of Roundup Biactive are lost permitting the drilling of crops 48 hours after application.
Mixing and spraying
ROUNDUP BIACTIVE mixes readily with water and can be applied in spray volumes ranging from 80-400 l/ha using tractor mounted, knapsack, rotary atomisers and hand-held sprayers. Specialised application equipment such as weed wipers and spot gun applicators may be used where indicated. Correctly calibrate all sprayers under field or use conditions prior to application.
a) Tractor mounted and powered sprayers
These should be capable of applying accurately 80-400 l/ha within a pressure range of 1.5-2.5 bars (20-35 psi). Half fill the spray tank with clean water, start gentle agitation, and then add the correct amount of ROUNDUP BIACTIVE. Top up the tank with water to the required level. To avoid foaming do not use top tank agitation. Use of a defoamer may be necessary.
Medium Volume application (150-300 l/ha)
Avoid high water volumes (>300 l/ha) which may lead to run-off from the treated vegetation, resulting in reduced control. Low drift nozzles such as air induction and preorifice types producing a medium or coarse spray (BCPC definition) should be used to minimise the risk of drift.
Low Volume Application (minimum 80 l/ha)
Low volume application can be achieved by reducing pressure and the appropriate nozzle selection. Low drift nozzles which produce a medium spray quality (BCPC definition) should be used to minimise the risk of drift.
b) Knapsack sprayers
Recommended delivery range is 80 - 300 l/ha. Half fill the spray tank with clean water, add the correct amount of ROUNDUP BIACTIVE and top up with water. Fill according to best practice as given on the CPA’s Voluntary Initiative website (www.voluntaryinitiative.org.uk) When used at a walking speed of 1 m/sec to apply a swath of 1 m width, most knapsack sprayers fitted with a Lurmark AN 2.0 or similar nozzle deliver approximately 200 l/ha spray volume (or 10 l per 500 m2). To apply 4.0 l/ha of ROUNDUP BIACTIVE, therefore, use a 2.0% solution, i.e. 200ml ROUNDUP BIACTIVE made up to 10 litres. Similarly, knapsack sprayers fitted with low volume nozzles such as Lurmark AN 1.0 typically deliver approximately 100 l/ha spray volume. To apply 4.0 l/ha ROUNDUP BIACTIVE in this case use 4.0% solution.
c) Rotary Atomisers
When rotary atomisers are used to apply ROUNDUP BIACTIVEensure that the droplet diameter falls within the range 200-300 microns for all uses. Stir the correct amount of ROUNDUP BIACTIVE to control the particular target species into the sprayer bottle half filled with clean water. Top up with water, close the top and shake gently to ensure good mixing
d) Weed Wipers
For ropewick applicators use a concentration of 1 part ROUNDUP BIACTIVE to 2 parts of water and add a water-soluble dye if required. Care should be taken to avoid dripping onto wanted vegetation. For new generation weed wipers, use 1 part Roundup Biactive to 10 or 20 parts of water or as directed by manufacturer’s instructions. A list of machines is included in the Company Advisory section at the end of this label.
e) Spot Gun Applicators
Spot gun applicators are for the treatment of individual weeds. Apply 5 ml of spray to target weed, using a narrow cone TG-3 or TG-5 nozzle.
Boat mounted sprayers For use in aquatic situations. Prepare sprayer as for knapsack sprayers (Section b above). Calibrate and spray at the lowest speed possible. Always apply against the direction of any current.
