A selective post-emergence herbicide for use on winter and spring cereals, forage maize and grassland to control a range of perennial and annual weeds, including cleavers, common chickweed, field forget-me-not, common hemp-nettle, black bindweed, volunteer potatoes, docks and common nettle.

An emulsifi able concentrate containing 200 g/litre fluroxypyr (20.4% w/w) as the 1-methyl heptylester.

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.

The rate of use of FLUROSTAR 200 is dependent on the weed, the size of weed and the tank-mix used as detailed below. Using standard nozzles the recommended spray volume is 150 to 400 litres water per hectare. The lowest volume should only be used in very open crops on small weeds. On later applications where the crop is dense the spray volume should be increased to 400 litres water per hectare. The minimum recommended pressure is 2 to 3 bars.
Apply FLUROSTAR 200 as a MEDIUM spray as defined by the BCPC system.
Add the appropriate amount of FLUROSTAR 200 to clean water in a half-filled sprayer tank, mix thoroughly and add the remainder of the water. The spray mix must be used immediately and agitated continuously during mixing and until
application is complete.

FLUROSTAR 200 is a translocated herbicide taken up by the leaves of weeds.

It is essential that the target weeds have fully emerged before application and that good spray of the weed foliage is achieved. Weeds which emerge after application are not controlled. Best results are achieved against small weeds growing actively under warm, moist conditions. These conditions are particularly important for the control of cleavers. Ensure that crops are vigorous with growth
unaffected by frost, pests, disease, nutrient defi ciency or moisture stress before treatment. Do not treat waterlogged crops or crops under drought stress.

Spring treatments (from 1st March onwards on winter crops).

Two-way mixtures with other broad-leaved weedkillers.
FLUROSTAR 200 is also compatible in two-way mixture with approved salt formulations of MCPA. Refer to the product label for weed susceptibilities, timing of application, etc, for this mixture. The addition of the recommended rate of approved salt formulations of MCPA to FLUROSTAR 200 is recommended where weeds such as common poppy, fat-hen and shepherd’s-purse are present.
The timing of application of FLUROSTAR 200 mixtures depends on the tank-mix partner but mixtures should not be applied after the fi rst node detectable stage (Zadoks 31).

VOLUNTEER POTATO CONTROL (winter wheat and winter barley only)
Timing - cereal crop stage
Apply 2.0 litres of FLUROSTAR 200 any time from the third node detectable stage of crop growth up to and including the fl ag leaf ligule just visible stage (Zadoks 33 to 39 inclusive) in 300 to 400 litres water per hectare using standard nozzles.
Weed control stage
Potato shoots from 10 cm up to 40 cm in height.
FLUROSTAR 200 will only affect shoots which have emerged at the time of spraying. FLUROSTAR 200 will not give complete control of top growth.
However, a good degree of stunting can be expected, which will reduce the competitive threat posed to these crops by this weed. Because volunteer potatoes can emerge over an extended period, sprays applied later in the recommended period will generally give better results.
The main factors for obtaining successful results are that there is suffi cient actively growing green foliage on the potatoes and that good coverage of this foliage is achieved, for example by use of suffi ciently high water volumes. In addition to the control of volunteer potato haulm this use of FLUROSTAR 200 will give a useful reduction in the viability of daughter tubers.
These warnings apply only for this high rate recommendation 2.0 litres/ha for FLUROSTAR 200. They do not apply where FLUROSTAR 200 is used at the standard rates for annual broad-leaved weed control (0.5 to 1.0 litre/ha). Avoid overlapping spray bouts.
Straw from cereals treated at these rates and timings with FLUROSTAR 200 may contain residues which could damage certain crops. Straw must not be incorporated back into the soil. When straw is disposed of by baling and carting it should be used only for animal bedding. Manure from such animal bedding should only be used on or before cereal or grass crops.
DO NOT PLANT WINTER BEANS or legumes in the same year as this treatment with FLUROSTAR 200.
DO NOT PLANT PEAS or other legumes in the spring following the treatment.
DO NOT TANK-MIX FLUROSTAR 200 WITH ANY OTHER PRODUCT when used as recommended above.

Newly sown and established grass leys and permanent pasture may be treated with FLUROSTAR 200 for the control of annual and perennial broad-leaved weeds when weeds are actively growing. Do not spray swards containing clovers or other legumes if there are important constituents of the sward.

Annual weeds - newly sown grass leys
Application of FLUROSTAR 200 at 0.75 litres/ha in a spray volume of 200 to 400 litres of water per hectare to give good coverage of the weeds will control common chickweed up to 50 mm. Grasses should have at least 3 fully expanded leaves.

Perennial weeds - established grassland
Apply FLUROSTAR 200 at 2.0 litres/ha in a spray volume of 300 to 400 litres of water per hectare to give good coverage of the weeds.

FLUROSTAR 200 should be applied in tank-mix with other products only if any requirements or restrictions on the other product label do not conflict with the requirements or restrictions for FLUROSTAR 200. Tank-mixes should not be allowed to stand in the tank and agitation should be maintained at all times.
Crops, timings, etc, can be affected by the rate and type of tank-mix partner used. always refer to the product label of the tank-mix partner.
Mix FLUROSTAR 200 in the spray tank fi rst except when mixing with water dispersible granules, wettable powders or suspension concentrates (flowables).
Each product should be added to the half-full sprayer tank and be fully dispersed before the addition of the next product.
FLUROSTAR 200 can be tank-mixed with a number of other herbicides to broaden the spectrum of weeds controlled. These other herbicides may have crop, timing, varietal and other restrictions which are different to those of FLUROSTAR 200. Tank-mixes should only be applied within label recommendations of every product in the mix.
For more information on possible tank mixtures, contact your distributor.

Apply to dry foliage.
For best results apply FLUROSTAR 200 when weeds are actively growing. In newlysown crops, seedling and small weeds are more susceptible to FLUROSTAR 200 and will respond quicker when treated at this stage. Vigorous crop competition enhances control of the more resistant weeds and prevents weeds which germinate after application from becoming a problem in the crop.
Crops undersown with grass may be sprayed provided the grasses are tillering.
Do not apply to crops undersown with clover or other legume-containing mixtures.
Keep livestock out of treated areas for at least 3 days and until poisonous weeds such as ragwort have died and become unpalatable.
FLUROSTAR 200 will only produce optimum results when the weeds are actively growing and the crop competitive. This is particularly important with cleavers.
FLUROSTAR 200 is of low volatility and is therefore not subject to vapour drift.
Do not spray in windy weather and avoid drift onto non-target crops/areas.
Do not treat crops under stress. Stress can be caused by many factors including frost, drought, waterlogging, trace element defi ciency, disease and pest attack etc.
Do not spray if night temperatures are low or if frost is imminent.
FLUROSTAR 200 used alone is rainfast one hour after application.
Do not roll or harrow 7 days before or after treatment.
Wash equipment thoroughly with water and detergent immediately after use.
Traces of FLUROSTAR 200 can cause harm to susceptible crops sprayed later.
