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.
WARNINGS
Read all warnings before applying GRAZON PRO.
Do not roll or harrow grass for 10 days before or 7 days after application. Do not spray in drought, very hot or very cold weather.
GRAZON PRO is safe to grass. Very occasionally some yellowing of the sward may occur; this is transient and quickly outgrown.
DO NOT sow kale, swedes, turnips or grass mixtures containing clover by direct drilling or minimum cultivation techniques within 6 weeks of applying GRAZON PRO.
GRAZON PRO residues in plant tissues (including manure and digestate) which have not completely decayed may affect succeeding susceptible crops e.g. peas, beans and other legumes, carrots and umbelliferae, potatoes and tomatoes, lettuce and other compositae. Do not plant susceptible autumn-sown crops (e.g. winter beans) in the same year as treatment with GRAZON PRO. Where susceptible crops are to be planted in the spring do not apply GRAZON PRO later than the end of July of the previous year.
Following good agricultural practice, ensure that plant remains have completely decayed before planting susceptible crops.
Do not use any plant material treated with GRAZON PRO for composting or mulching.
Do not use manure from animals fed on crops treated with GRAZON PRO for composting.
In hot conditions, vapour drift may occur, making it particularly important to assess the risk to neighbouring vegetation.
Take extreme care to avoid drift onto crops and non-target plants outside the target area.
Do not apply directly to, or allow spray drift to come into contact with agricultural or horticultural crops, amenity plantings or gardens, ponds, lakes or water courses.
All conifers, especially pine and larch, are very sensitive to spray drift.
Grazing Interval
Exclude livestock during treatment and do not allow livestock to graze treated grassland for at least 7 days following treatment, and until foliage of any poisonous weeds which may have been affected by application has died and become unpalatable.
 
WEEDS CONTROLLED, RATE OF USE AND APPLICATION TIMING
The following weeds will be controlled by an application of GRAZON PRO at a rate of 60 mL of product in 10 litres of water (6 mL product in 1 litre of water).
The weeds should be thoroughly wetted with the spray solution but spraying until "run-off" will decrease activity. The use of flood jets is recommended to prevent drift. Care should be taken to avoid local overdosing.
If the grass has been cut for hay or silage or grazed leave for 2-3 weeks to allow sufficient re-growth to occur before spraying. Grass and weeds must be actively growing to ensure good weed control and minimal check to the grass.
To allow maximum translocation of GRAZON PRO to the roots do not cutgrass for 28 days after application.   
 
 Weeds                                             Optimum timing of application
Common nettle                                Spray when actively growing but preferably before flowering (normally up to mid-June).
Broad-leaved dock /Curled dock     Treat in the spring when the docks are in the rosette stage up to 25 cm high. On large well-established docks, or where there is a high reservoir of seed in the soil,a second application the following year may be required.
Creeping thistle                               Spray when actively growing but before flowering spikes are 15 cm high. Application of GRAZON PRO at flowering or during seeding is likely to produce reduced levels of control.
Bramble, broom and gorse               Spray in June-August when actively growing but before plants begin to senesce in the autumn. It is essential that, particularly with large bushes, all the foliage is  thoroughly wetted or incomplete kill may result.
 
APPLICATION  EQUIPMENT
Apply GRAZON PRO using a hand-held sprayer. Ensure the equipment is in good working order and has been calibrated according to the manufacturers’ recommendations.
Wash out spray equipment thoroughly with water and detergent immediately after use. Traces of GRAZON PRO could cause harm to susceptible crops sprayed later.
DO NOT APPLY through hand-held rotary atomiser equipment.
