For use as a contact and residual herbicide in wheat, barley, oats, triticale, linseed and for use on green cover on land not being used for crop production, e.g. set-aside.
FINY is a water soluble granule formulation containing 200 g/kg metsulfuron-methyl.

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.
FINY is a selective herbicide used for annual broad-leaved weed control in wheat, barley, oats, triticale, linseed and green cover on land temporarily removed from production e.g. set-aside. It can be absorbed both through the roots and the foliage, and is rapidly translocated within the weed. It acts by stopping plant cell division and works quickly so that susceptible weeds stop growth almost immediately after post-emergence application, and are usually killed within 7-21 days depending upon weed species. Those weeds which are not killed will still generally give less competition to the crop.
FINY will give most effective weed control when applied to weeds that are small, and actively growing at the time of application.
FINY can be safely used on all varieties of winter and spring wheat, spring barley, oats, triticale and linseed. Winter barley variety Igri must not be treated before leaf-sheath erect stage of growth. Earlier treatment may cause a check to growth and ear distortion. Do not use on undersown crops or crops that will be undersown.

WEED RESISTANCE
When herbicides with the same mode of action are used repeatedly over several years in the same field strains of weeds resistant to herbicides may develop. Resistant species survive a correctly-applied treatment at the recommended dose. It is recommended that FINY is used as part of a cropping programme which includes the use of herbicides with different modes of action. Do not rely on one herbicide mode of action in the same field over several years.

Key aspects of the FINY weed resistance management strategy are:
Always follow the WRAG guidelines for preventing and managing herbicide resistance. Copies of the guidelines are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.
Development of resistance within a weed species can be avoided or delayed by sequencing or tank-mixing with suitable products having a different mode of action.
FINY is a sulfonylurea herbicide whose mode of action is via ALS inhibition. Do not use FINY, or any other ALS inhibitor herbicide, as a sole means of broad-leaved weed control in successive crops.
Always use broad-leaved weed herbicides with non-ALS mode of action throughout the crop rotation.
Always monitor effectiveness of weed control and investigate any occurrences of poor effectiveness. If unexplained failure occurs, contact your agronomist who may consider a resistance test appropriate.

RESTRICTIONS
Do not apply to flax.
Do not apply to crops which are under stress at time of application, e.g. drought, waterlogging, low temperatures, nutrient or lime deficiency, pest or disease attack etc.
Do not apply in sequence with any other product containing sulfonylurea herbicides or ALS inhibiting herbicides.
Do not roll or harrow within one week of application.

FINY is extremely active at very low concentrations. Take extreme care to avoid:
- overlap of spray swaths - drift on to broad-leaved plants outside the target area
- drift on to surface waters and ditches
- draining of spraying equipment on land to be used for any crop except cereals. In cereals the application must not be made before 1st February. Contract agents should be consulted before using FINY on crops grown for seed.

WEED CONTROL
Apply to small actively growing weeds for most effective weed control. Soil should be moist at the time of application but foliage should not be wet.

CROP SPECIFIC INFORMATION
Application Rate and Water Volume
For all crops apply FINY at 30 g/ha in 100-200 litres water per hectare as a medium quality spray (BCPC definition). Where crop or weed cover is dense increase the water volume to 400 l/ha. Make only one application per year.

Timing of Application
Wheat and oats Apply from the 2 leaf stage to before the flag leaf sheath extending stage (GS 39).
Barley and triticale Apply from 3 leaf stage to before flag leaf sheath extending stage (GS 39).
Linseed Apply from first pair of true leaves unfolded until before flower buds visible up to 30 cm tall, whichever is the sooner. Allow an interval of 10 days before applying other pesticides if the crop is growing poorly or is under stress.
Set-aside FINY can be used on set-aside land temporarily removed from agriculture. Before applying to land that is part of a grant aided scheme, ensure compliance with the management rules of that scheme. Apply before 1st August in the year of application. Where established grass species are the main cover crop, some discolouration and stunting may occur. FINY should not be used on seedling grasses. On set-aside land FINY is effective for the control of docks with the best control achieved from application 3 weeks before or after cutting.

FOLLOWING CROPS
Only cereals should be planted within 16 months of applying FINY to a linseed crop or to green cover on land not being used for crop production. Only sow wheat, barley, rye, triticale, oilseed rape, field beans and grass to succeed a cereal crop treated with FINY
Refer to ‘Compatibility’ section for specific advice concerning following crops permitted after use of FINY with other sulfonylurea and ‘ALS inhibiting’ herbicides.

MIXING AND SPRAYING
Ensure sprayer is clean, in good working order and calibrated prior to use
Half fill the spray tank with clean water and begin agitation. Add the required amount of FINY to the spray tank. Add the remainder of the water and continue agitation during spraying.
When using in a tank mix, always add FINY to the spray tank first and ensure it is completely dispersed before adding the partner product.
IMMEDIATELY AFTER SPRAYING IS COMPLETE, WASH OUT THE SPRAYER WITH WATER AND SUITABLE TANK WASHING PRODUCT TO ENSURE THAT THE EQUIPMENT IS COMPLETELY DECONTAMINATED. TRACES OF FINY REMAINING IN OR ON THE SPRAY TANK MAY RESULT IN DAMAGE TO CROPS SPRAYED LATER.
Dispose of tank wash safely and do not spray on to susceptible crops or land intended for planting with susceptible crops.

COMPATIBILITY
Note: In linseed, FINY should not be tank-mixed.
In wheat and barley FINY can be applied alone or in mixture. Do not use FINY in tank-mix on oats and triticale.
It is important to follow the recommendations of the mixture product as well as FINY, and always add the FINY to the spray tank first.
Do not mix with chlorpyrifos. Allow at least 14 days between FINY and chlorpyrifos treatments
Apply FINY alone, or in mixture to crops which are healthy at the time of application and suffering no stress or deficiencies.
