A soluble concentrate containing 540 g/l glyphosate, present as 662g/l (48.7%
w/w) of the potassium salt of glyphosate.
 
DIRECTIONS FOR 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
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 ULTIMATE IN GALVANISED OR UNLINED STEEL CONTAINERS OR SPRAY TANKS.
DO NOT LEAVE SPRAY MIXTURES IN THE TANK FOR LONG PERIODS AND MAKE SURE TANKS ARE WELL VENTED.
 
Restrictions
A period without rain of at least 6 hours, and preferably 24 hours, must follow application of ROUNDUP ULTIMATE herbicide.
Do not spray on to weeds suffering from drought, water-logging, heat or frost, otherwise poor control may result.
Do not spray in windy conditions as drift onto desired plants or crops could severely damage or destroy them.
 
Weeds controlled
ROUNDUP ULTIMATE herbicide controls most emerged grasses and broadleaved weeds. Where re-growth occurs re-treatment will be necessary. Apply ROUNDUP ULTIMATE 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 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 presenescence.
OTHER SPECIES - recommendations for specific Areas of Use are given in the Recommendation Tables, pages 9-15.
This product will not give an acceptable level of control of Horsetails (Equisetum arvense) – repeat treatment will be necessary.
 
Following crops
Upon soil adsorption the herbicidal properties of ROUNDUP ULTIMATE are lost permitting the drilling of crops 48 hours after application.
 
Other Specific Restrictions:
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. For weed wiper applications, the maximum concentrations must not exceed the following: (a) weed wiper mini - 1:3.5 dilution with water (b) other wipers - 1:2 dilution with water.
 
Mixing and spraying
ROUNDUP ULTIMATE 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 ULTIMATE. 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. Nozzles such as Lurmark 04- F110, 08-F110 or Tee Jet 11004, 11008 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 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 ULTIMATE 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 2.6 l/ha of ROUNDUP ULTIMATE, therefore, use a 1.3% solution, i.e. 130ml ROUNDUP ULTIMATE 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 2.6 l/ha ROUNDUP ULTIMATE in this case use 2.6% solution.
c) Rotary Atomisers
When rotary atomisers are used to apply ROUNDUP ULTIMATE ensure that the droplet diameter falls within the range 200-300 microns for all uses. The water volume must be 40 litres/ha. Stir the correct amount of ROUNDUP ULTIMATE 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
Use a concentration of 1 part ROUNDUP ULTIMATE to 3.5 parts of water and add a water-soluble dye if required. Care should be taken to avoid dripping onto wanted vegetation. 
e) Spot Gun Applicators
Spot gun applicators are for the treatment of individual weeds. Apply 4 ml of spray to target weed, using a narrow cone TG-3 or TG-5 nozzle.
 
Compatibility
Do not tank mix Roundup Ultimate 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).
 
General Information
ROUNDUP ULTIMATE herbicide is an advanced formulation containing the potassium salt of glyphosate. ROUNDUP ULTIMATE 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 ULTIMATE 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 ULTIMATE, glyphosate, is practically immobile in soils and is, therefore, unlikely to contaminate groundwater.
 
Agronomic Advice
Applied pre-harvest of specified crops, ROUNDUP ULTIMATE provides, in addition to weed control, a diverse range of harvest management benefits accruing from uniform ripening of the crop. It is recommended for cleaning up weedy ground prior to planting or sowing. Applications of lime, fertiliser, farmyard manure and pesticides should be delayed until 5 days after application of ROUNDUP ULTIMATE. After application, large concentrations of decaying foliage, stolons, roots or rhizomes should be dispersed or buried by thorough cultivation before crop drilling. To maximise the safety of Roundup Ultimate to operator, consumer and environment, the label recommendations and the DEFRA/HSC/NAW publication "Code of Practice for using Plant Protection Products” of January 2006 should be adhered to.
 
Symptoms on 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.
