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 RODEO 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.
 
Restrictions
A period of at least 6 hours and preferably 24 hours rain-free must follow application of Rodeo.
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 applicat ion, otherwise poor control may result.
Do not spray in windy conditions as drift onto desired crops or vegetation could severely damage or destroy them.
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 RODEO unless cultivation and drilling of the next crop has taken place.
 
Weeds controlled
RODEO 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 RODEO herbicide where there is full emergence of grasses and broad-leaved weeds 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 pre- senescence.
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.
 
Following Crops
Upon soil adsorption the herbicidal properties of Rodeo are lost permitting the drilling of crops 48 hours after application.
 
Sprayer Hygiene
It is essential to thoroughly clean-out spray tanks, pumps and pipelines and nozzle or disc assemblies, with a recommended detergent cleaner, between applying this product and other pesticides to avoid contamination from pesticide residues. Traces of Rodeo left in the equipment may seriously damage or destroy crops sprayed later.
 
Mixing and spraying
Correctly calibrate all sprayers under field or use conditions prior to application. a) Conventional Hydraulic Sprayers Knapsack sprayers and tractor mounted or powered sprayers may be used. These should be capable of applying accurately 80-400 l/ha within a pressure range of 1.5-2.5 bars (20-35 psi).
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 producing a medium or coarse spray (BCPC definition) should be used to minimise the risk of drift :Knapsack Hypro AN 2.0, AN 4.0 Cooper Pegler Floodjet green, red; Tractor Hypro 04-F110, 08-F110 Tee Jet 11004, 11008
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 (BCPC definition) should be used to minimise the risk of drift:Knapsack Cooper Pegler VLV 100 Hypro AN 1.0; Tractor Hypro Lo Drift
 Filling the Sprayer
Knapsack Half fill the spray tank with clean water, add the correct amount of RODEO and top up with water. Mix thoroughly. ·
Tractor Mounted To avoid foaming do not use top tank agitation. Half fill the spray tank with clean water, start gentle agitation, then add the correct amount of RODEO. Top up the tank with water to the required level. Use of a defoamer may be necessary.
b) Rotary Atomisers – for use in orchards
When rotary atomisers are used to apply RODEO ensure that the droplet diameter falls within the range 200-300 microns for all uses.
c) Hand-held Wipers
RODEO may be applied through the weed wiper mini. Use a concentration of 1 part RODEO to 2 parts of water and add a scarlet dye if required. Care should be taken to avoid dripping onto wanted vegetation.
d) Cut Stump Application
Enso attachment to rotary saws: This technique is specific to scrub clearance in forestry. A water-soluble dye may be added to RODEO to help identify treated stumps.
 
HAND-HELD EQUIPMENT: SPECIFIC GUIDANCE
e) Knapsack Sprayer Applicators
When used at a walking speed of 1 m/sec to apply a swath of 1 m width, most knapsack sprayers deliver 200 l/ha spray volume (or 10 litres per 500 m²). To apply 4.0l/ha of RODEO, therefore, use a 2% solution (e.g. 200 ml RODEO made up to 10 litres). When used as above, knapsack sprayers fitted with low volume nozzles typically deliver 100 l/ha spray volume (or 10 litres per 1000 m²). To apply 4.0l/ha RODEO in this case, use a 4% solution.
Filling the sprayer - hand-held machines
Stir the correct amount of RODEO into the sprayer half filled with clean water. Top up with water, close the top and shake gently to ensure good mixing.
f) Spot Gun Applicators – for treatment of individual weeds
Apply 5 ml of spray to target weed, using a narrow cone TG-3 or TG-5 nozzle.
 
Compatibility
Do not tank mix Rodeo 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). RODEO is compatible with Mixture B (ADJ 0161). Where conventional hydraulic sprayers are being used Mixture B may be added to the spray tank solution, at a rate of 2% of the final water volume, for all pre-plant and post-plant directed sprays only. DO NOT APPLY WITH MIXTURE B TO EDIBLE CROPS, OR GRASSLAND WEEDS. Do not tank-mix RODEO when using rotary atomiser sprayers.
