EXTREME CARE SHOULD BE TAKEN TO AVOID SPRAY DRIFT AS THIS CAN SEVERELY DAMAGE NEIGHBOURING CROPS OR PLANTS. DO NOT MIX, STORE OR APPLY ROUNDUP FLEX 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.

 

A period without rain of at least 6 hours and preferably 24 hours must follow application of ROUNDUP FLEX. Do not spray onto weeds which are naturally senescent, or where growth is impaired by drought, high temperatures, a covering of dust, flooding or 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 damaged or destroy them. Do not tank-mix ROUNDUP FLEX with adjuvants, pesticides or fertilisers, except as specified in the Compatibility section. After application, large concentrations of decaying foliage, stolons, roots or rhizomes should be dispersed or buried by thorough cultivation before crop drilling. Applications of lime, fertiliser, farmyard manure and pesticides should be delayed until 5 days after application of ROUNDUP FLEX.

 

ROUNDUP FLEX 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. Apply ROUNDUP FLEX herbicide once grasses and broad-leaved weeds have emerged and they haveACTIVELY 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 retreatment.

BRACKEN should be treated after frond tips are unfurled, but presenescence.

OTHER SPECIES - recommendations for specific Areas of Use are given in the Recommendation Tables This product will not give an acceptable level of control of Horsetails (Equisetum arvense) – repeat treatment will be necessary. Note: The effects of treatment on the long-term control of perennial broadleaved weeds have not been investigated.

 

ROUNDUP FLEX herbicide controls emerged and floating aquatic weeds including Common Reed, Reed Sweet-grass, Reed Canary-grass and Waterlily. Treat when the weeds are actively growing with full emergence of green leaf, at flowering and before dieback. Best results are obtained from applications Page 6 in the periods from mid-July to mid-August on Water-lilies and mid-August to mid-September on reeds.

 

Upon soil adsorption the herbicidal properties of ROUNDUP FLEX are lost permitting the drilling of crops 48 hours after application. See the „Recommendation Tables‟ for specific restrictions.

 

 

 

Users must consult the appropriate water body (Environment Agency/Scottish Environmental Protection Agency) before using the product near water and must obtain their agreement before using this product to control aquatic weeds. The maximum concentration of active substance in treated water should not exceed 0.2 ppm. When applying through rotary atomisers, the spray droplet spectra produced must be of a minimum Volume Median Diameter (VMD) of 200 microns. Weed wipers may be used in any recommended crop where the wiper or chemical does not touch the growing crop. When using weed wipers, the maximum concentrations used must not exceed the following: Weed wiper Mini 1:3 dilution with water Other Wipers 1:2 dilution with water .

 

ROUNDUP FLEX 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 hydraulic 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 FLEX. 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 pre-orifice 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 FLEX and top up with water. Fill according to best practice as given on the CPA‟s Voluntary Initiative website (www.vountaryinitiative.org.uk) When used at a walking speed of 1 metre/second to apply a swath of 1 metre 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 3.0 l/ha of ROUNDUP FLEX, therefore, use a 1.5% solution, i.e. 150ml ROUNDUP FLEX 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 3.0 l/ha ROUNDUP FLEX in this case use 3.0% solution.

c) Rotary Atomisers

Hand-held machines can be used to apply a spray volume of 10-40 l/ha, e.g. Herbi and Herbaflex. When rotary atomisers are used to apply ROUNDUP FLEXensure that the droplet diameter falls within the range 200-300 microns for all uses. Stir the correct amount of ROUNDUP FLEX 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 FLEX to 3 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 1part ROUNDUP FLEX 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 5ml 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.

 

Do not tank mix ROUNDUP FLEX with adjuvants, pesticides or fertilisers except as advised by Monsanto. For up to date information on compatible products contact Monsanto UK Limited (tel: 01954 717575). Do not tank-mix ROUNDUP FLEX when using rotary atomiser sprayers. Page 16 For hydraulic sprayers: maintain continuous agitation when using ROUNDUP FLEX in tank mixture. For knapsack sprayers: mix thoroughly and use immediately when using ROUNDUP FLEX in tank mixture.

 

ROUNDUP FLEX herbicide is an advanced formulation containing glyphosate. ROUNDUP FLEX is taken up by foliage and translocated to underground roots, rhizomes and stolons, providing control of both annual and perennial grasses and broad-leaved weeds. ROUNDUP FLEX is rapidly adsorbed onto particulate matter in soils and water and is quickly degraded by the micro-organisms present in soil and aquatic bottom sediments. Until degraded, the active ingredient in ROUNDUP FLEX, glyphosate, is practically immobile in soils and is, therefore, unlikely to contaminate groundwater. ROUNDUP FLEX is a glyphosate formulation which, having no hazard classification, offers a high standard of operator safety. To maximise the intrinsic safety of ROUNDUP FLEX to operator, consumer and environment, the label recommendations and the DEFRA/HSE/DETR publication "Code of Practice for Using Plant Protection Products” of January 2006, should be adhered to.

 

Symptoms of treatment are generally first seen 7-14 days, or longer, if growth is slow after spraying. Leaf symptoms take the form of a reddening then yellowing of the foliage and are first seen on the grass weeds but take longer to appear on broad-leaved weeds. Reaction of nettle is slow. For aquatic weed control, on reeds and grasses leaf symptoms usually appear within 14-21 days of spraying in the early autumn. Complete foliage desiccation usually occurs 30-40 days after spraying. At this stage the reeds can be cut and removed. During cold conditions leaf symptoms may not appear before natural dieback but no growth will occur in the season following spraying.

 

See Directions for Use (Restrictions). ROUNDUP FLEX will remain efficacious at low but not freezing temperatures however the onset of symptoms will be delayed. A covering of dew may reduce efficacy where run-off occurs. Reduced control is likely where weed growth is impaired by natural senescence, drought, high temperature, a covering of dust, flooding or severe/prolonged frost at, or immediately after application.
