Ardee is a systemic herbicide, as a soluble concentrate, for the control of most broad-leaved and grass weeds in: Barley Durum wheat Field beans Forest Nursery Grassland Green cover in land not being used for crop production Linseed Non-cropped areas Oats Oilseed rape Orchards: apple, pear, cherry, damson and plum Peas (combining) Stubbles of all edible and non-edible crops Wheat.

GENERAL INFORMATION
Ardee is a foliar acting herbicide that controls annual and perennial grasses and most broad-leaved weeds when used as directed. It is translocated from treated vegetative growth to underground roots, rhizomes or stolons. Leaf symptoms, being a reddening then yellowing of the foliage, are first seen on grass weeds but take longer to appear on broad leaved weeds.
It is particularly important that the weeds have sufficient leaf growth and are actively growing when treated.
Perennial grass weeds must have produced fresh leaves, which are green and vigorous. Common couch/scutch is most susceptible to Ardee when it is tillering and when new rhizomes have begun to grow. This is usually when the plants have about 5 - 6 leaves, each with approximately 12-15cm of new growth.
The majority of perennial broad-leaved weeds are most susceptible if treated when they are actively growing and are at or near flowering stage. Annual weeds should be actively growing with grasses having at least 5cm of leaf and broad-leaved weeds at least two expanded true leaves when sprayed. Couch/scutch grasses and other grass and broad-leaved weeds are less susceptible to Ardee when growth is restricted by drought, waterlogging, frost, very high temperatures or natural dieback. Efficacy will be reduced if such conditions occur at or immediately after spraying.
Occasionally a slight check to crop growth may occur, particularly after direct drilling when crop seeds germinate amongst a mass of decaying foliage, stolons, rhizomes or roots. Thorough cultivations are necessary to disperse or bury decaying organic matter. Consolidate loose soils and ensure crops are adequately fertilised and appropriate measures are taken to prevent insect and fungal damage to the following crop, especially where following grassland. Do not apply lime, fertiliser, farmyard manure, pesticides or similar materials within 7 days of Ardee. Note: Ardee does not give acceptable control of horsetail (Equisetum arvense).

WICK/WIPER APPLICATORS
Certain weeds, particularly those with an erect growth habit and having a spatial separation from desirable species, can be effectively controlled by wiping a concentrated solution of Ardee onto the leaves or stems. Weeds must be actively growing at application. Do not apply when rain is expected as, apart from unsatisfactory weed control, herbicide might be transferred to desirable species by rain splash or foliar contact.
Ardee dilution
Humid conditions 1 volume Ardee: 1 volume water
Warm, dry conditions 1 volume Ardee: 2 volumes water

Caution
Ensure that there is a minimum 5 cm between the top of the tallest desired vegetation and the impregnated wiper.

OPTIMUM TIME TO SPRAY
As Ardee is absorbed through the leaves and is translocated by the weeds own transport systems, it is particularly important that the weeds have sufficient leaf growth and are actively growing when treated.
Couch/scutch is most susceptible to Ardee when it is tillering and when new rhizomes have begun to grow. This is usually when the plants have about 5-6 leaves, each with approximately 12-15 cm of new growth.
Couch/scutch grasses and other grass and broad-leaved weeds are less susceptible to Ardee when growth is restricted by drought, waterlogging, frost, very high temperatures or natural dieback.

MIXING
Pour the recommended quantity of Ardee into the spray tank already half-filled with water. Top up the spray tank with water to the required level. Agitate thoroughly to mix the spray solution. Spray out on the day of mixing, maintaining agitation. Do not mix, apply or store Ardee in galvanised or unlined mild steel containers or tanks. Keep tanks well vented and clear of all sources of ignition. RINSE CONTAINER THOROUGHLY by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of safely.

APPLICATION & SPRAY QUALITY
Prepared spray solution should be applied as a MEDIUM spray at nozzle pressures not exceeding 2.5 bar (35 psi). Ardee is a systemic herbicide, active at low doses. Always take care to avoid spray drift. DO NOT SPRAY in windy weather or near to desirable species or amenity plants.

WEATHER
Avoid spraying if rain is expected within 12 hours. Applications are best made under dull, humid conditions. Weeds restricted by water stress may not be satisfactorily controlled. DO NOT spray during frosty weather or under windy conditions likely to result in spray drift.

SOILS
Ardee may be used to control weeds on all mineral or organic soils or surfaces, including ash and gravel. Only weeds showing green leaf at the time of application can be killed. There is no residual activity with Ardee. Owing to soil variations, some couch/scutch grasses may not be at a susceptible stage when sprayed and the treatment should be repeated in the following autumn for complete control.

DECAYING VEGETATION
Occasionally a slight check to crop growth may occur, particularly after direct drilling when crop seeds germinate amongst a mass of decaying foliage, stolons, rhizomes or roots. Thorough cultivations are necessary to disperse or bury decaying organic matter. Consolidate loose soils and ensure crops are adequately fertilised and appropriate measures are taken to prevent insect and fungal damage to the following crop, especially where following grassland.

COMPATIBILITY
Ardee may be applied in tank mix with Barclay Addup or other approved tallow amine ethoxylate surfactant. DO NOT apply lime, fertiliser, farmyard manure or similar materials within 7 days of Ardee.

FUTURE PLANTING
Ardee has no long-lasting herbicidal activity in soils after application. Agricultural and horticultural quality soils with perennial grass and broad-leaved weed burdens may be planted up with trees after not less than 7 days after application. It is preferable to plant most amenity plants after the treated vegetation has died back or after cultivation lest they be contaminated or smothered by the collapsing weed vegetation. Under normal weather conditions, cultivations may be conducted 5 days after treatment. Under poor growing conditions wait for the characteristic red/yellow leaf symptoms to appear on perennial weeds before cultivating.

RESISTANT STRAINS
Strains of some annual grasses, e.g. black-grass, wild-oat and Italian rye-grass, have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. Guidelines are available from your distributor, crop advisor or product manufacturer.
