DIRECTIONS FOR USE
 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 occur if 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.
 
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 (Zadoks 11) up to and including the 2nd node detectable stage (Zadoks 32 inclusive). 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. Sequences should only be applied within the label recommendations of every product in the sequence.
 
Best Use Advice - Autumn
Apply Broadway Star at 265 g/ha with a Dow AgroSciences supported adjuvant – Abacus, Activator 90, Bio-syl, Buzz, Drill, Headland Diamond, Headland Fortune, Intracrop Felix, Intracrop Warrior, Kantor, Kinetic, Respond, Roller, Spartan, Spryte Aqua, Torpedo II, Viking
Sterile and Great Brome control is best achieved in the autumn - Apply Broadway Star in a programme following an effective preemergence herbicide, in tank mix with a residual partner when brome is between GS 11-24 (optimal GS 11-13) - see reverse
Ryegrass control is best achieved GS 11-29
Wild oat control is best achieved GS 11-29 – Also good activity on tame oats optimum GS 11-24 – Best control achieved pre-tillering – Varietal differences in sensitivity/ optimal timing Consult Dow AgroSciences for latest varietal information
To avoid subsequent injury to crops other than wheat, rye and triticale, spray equipment used for Broadway Star applications should be thoroughly cleaned with All Clear Extra
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.
