A water dispersible granule containing 7.08 %w/w pyroxsulam, 7.08% cloquintocet-mexyl and 1.42% w/w florasulam.

A post-emergence ALS inhibitor (HRAC group B) for use on all varieties of WINTER WHEAT , WINTER RYE and TRITICALE for the control of WILD OATS, RYEGRASS, STERILE BROME and broad-leaved weeds.
Use only as part of a resistance management strategy that includes cultural methods of control and does not use ALS inhibitors as the sole chemical method of grass weed control.

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.

GENERAL INFORMATION
BROADWAY® STAR has foliar activity against wild oats, ryegrass, sterile brome and broad-leaved weeds.
The ideal timing for application is when the weeds are small and actively growing. As BROADWAY STAR is mainly foliar acting it is essential to ensure good coverage. The effectiveness of BROADWAY STAR may be reduced when soils are very dry, or temperatures are low and subsequently weed growth is slow. Susceptible weeds that germinate after application will not be controlled.

NOTES
Avoid overlapping of spray swaths.
BROADWAY STAR is rainfast in one hour.
Do not spray when crops are under stress from cold, drought, water logging, pest damage, nutrient deficiency etc.
Do not roll or harrow 7 days before or after application.
Take extreme care to avoid drift onto susceptible crops, non-target plants or waterways. Do not apply directly to, or allow spray drift to come into contact with agricultural or horticultural crops, amenity plantings, gardens, ponds, lakes or watercourses.
Crop injury may occurif BROADWAY STAR is applied in tank mixture with plant growth regulators. A minimum interval of 7 days between applications should be observed.

To avoid crop injury do not apply BROADWAY STAR in tank mixture with an organophosphate insecticide. A minimum interval of 14 days between applications should be observed.

WEED RESISTANCE
BROADWAY STAR is a product with an ALS inhibitor mode of action (HRAC group B).
Strains of some annual grasses (e.g. blackgrass, 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. Guidelines have been developed by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop advisor or product manufacturer.
BROADWAY STAR + an authorised adjuvant should be used in a programme. Following application of a pre-emergence product BROADWAY STAR should be used in tank-mixture with products with a different mode of action. Control may be reduced if BROADWAY STAR + an authorised adjuvant is applied alone.
No more than one application of ALS inhibiting herbicides with claims for the control of grass weeds should be applied for grass weed control.

MANAGEMENT OF RESISTANT BLACKGRASS
For good resistance management and where resistance is known or suspected to be present to substituted ureas, dinitroanilines or ACCase inhibitors the following is recommended.
1. Good cultural techniques such as drilling date and seedbed preparation should be adopted.
See WRAG guidelines.
2. Use only as part of a resistance management strategy that includes cultural methods of control and does not use ALS inhibitors as the sole chemical method of grass-weed control.
3. Use mixtures of herbicides with different modes of action at full-recommended dose rates.
4. Apply herbicides at optimum timing and environmental conditions.
5. A recommended sequence in such a situation would be a pre-emergence product followed by a tank mix of BROADWAY STAR at 265 g/ha + an authorised adjuvant + a grassweed product with an alternative mode of action.
This should be applied within 4 weeks of the pre-emergence treatment. Where weather conditions have prevented an application of BROADWAY STAR + adjuvant in the autumn a spring application can be made provided that it is used as part of a planned programme of products utilising different modes of action.
Contact Dow AgroSciences for recommended programmes.
6. To avoid the build up of resistance do not make more than one application of ALS inhibiting herbicides with claims for the control of grass weeds to any crop.

FOLLOWING CROPS
Crops that can be sown after a crop treated with BROADWAY STAR:

Autumn
Winter wheat and barley, winter oats, winter triticale, winter rye, oilseed rape, grass, winter beans, brassica plants as transplants
Spring:
Spring wheat, spring barley, spring oats, triticale, rye, spring oilseed rape, sugar beet, potatoes, grass, clover (as part of a grass/clover ley), beans, peas, maize, linseed, brassica plants as transplants, carrots, parsnips
Following a sequence of BROADWAY STAR and metsulfuron-methyl, treated ground should be ploughed to a depth of 15 cm before establishing winter oilseed rape.
Vigour reductions may be seen in following crops of oilseed rape after a dry summer. This will be outgrown and will not result in yield loss.

CROP FAILURE
In the event of a crop failure after a crop has been treated with BROADWAY STAR + an authorised adjuvant before February 1st only the following crops may be planted after ploughing to a depth of at least 15 cm;
Spring wheat, spring barley, grass or maize. At least 6weeks must elapse between treatment and redrilling.
Where crop failures occurs following an application after February 1st , plough and then allow 6 weeks before planting grass or maize.

RATE OF USE
BROADWAY STAR should be applied at 265 g/ha with an authorised adjuvant at manufacturers recommended rates.

ADJUVANTS
Authorised adjuvants are esterified and methylated rapeseed types, and those containing alkoxylated fatty amines, polyoxyalkylene glycol and alcohol ethoxylates.

CROPS
BROADWAY STAR + an authorised adjuvant can be used on all varieties of winter wheat, winter rye and triticale.

TIMING
BROADWAY STAR + an authorised adjuvant should be applied from 1 leaf (GS 11) and before third node detectable stage (before GS 33).
BROADWAY STAR + an authorised adjuvant must be applied during periods of active growth i.e. warm temperatures and moist conditions.

SPRAY PROGRAMMES
BROADWAY STAR + an authorised adjuvant should be used in a programme of pre - emergence products, followed by a tank mixture of BROADWAY STAR + an authorised adjuvant and products with a different mode of action. Control may be reduced if BROADWAY STAR + an authorised adjuvant is applied alone.
Only one application of BROADWAY STAR + an authorised adjuvant in a spray programme may be made.

JOINT APPLICATION
A joint application is the use of a product in tank mixture or sequence with another product (for joint application please refer below).
Ally Express, Harmony M SX, Ally Max SX, Harmony SX, Ally SX, Lorat,e Biplay SX, Boxer Calibre SX, Presite SX, Quantum, Finish SX, Starane Gold, Starane XL, Galaxy Thor,GEX 353.

The maximum total dose of florasulam applied to the crop must not exceed 7.5 g. For autumn planted crops a maximum total dose of 3.75 g of florasulam must be observed for applications made between crop emergence in the year of planting and February 1st in the year of harvest. Apart from these specific joint applications BROADWAY STAR must NOT be applied with any other product containing an ALS inhibitor, for example amidosulfuron. These sequences must only be used with a robust non-ALS inhibitor autumn herbicide programme. This is especially important where both products are applied in the spring. Do not apply other products containing ALS inhibitors in sequence with BROADWAY STAR for the control of common chickweed in order to avoid increased selection for herbicide resistant individuals. Following a joint application of BROADWAY STAR and metsulfuron-methyl, treated ground should be ploughed to a depth of 15 cm before establishing winter oilseed rape.

SOIL
BROADWAY STAR may be used on all soil types. On light soils some crop vigour effects may be observed. These are transient symptoms and will not affect crop yield.

APPLICATION
BROADWAY STAR + an authorised adjuvant should be applied through tractor-mounted hydraulic sprayers providing they are in good working order and have been calibrated according to the manufacturers’ recommendations.
Do not apply through CDA applicators.

WATER VOLUME
Apply BROADWAY STAR + an authorised adjuvant in 100 to 200 litres of water per hectare. The lower volume must only be used in open crops on small weeds.

SPRAY QUALITY
Apply BROADWAY STAR as a FINE to MEDIUM spray as defined by the BCPC system. Nozzles that deliver a MEDIUM to COARSE droplet size e.g. Air Induction types are not recommended as product performance may be reduced.

MIXING
Half fill the spray tank with clean water. Maintain agitation levels at all times.

Option 1: Using an Induction Bowl
Ensure adequate suction at outlet in base of bowl and rinse bar is working. Add required amount of BROADWAY STAR by pouring the granules at a controlled flow directly into the opening to the suction pipe outlet. Avoid the granules bridging or adhering to internal surfaces whilst filling.

Option 2: Top Tank Loading
Remove tank lid and filter basket. Add required amount of BROADWAY STAR by pouring the granules at a controlled flow into the agitating water. Ensure BROADWAY STAR is dispersed and does not adhere to internal structures such as tank sprinklers.

Add the remainder of the clean water, maintaining agitation until spraying is complete
