• It contains 60 g/L clopyralid + 240 g/L triclopyr. This combination provides excellent control of broad-leaved dock, curled dock, creeping thistle, spear thistle and common nettle and also has an effect on a large range of other weeds – see our weed list
• It is one of very few products with a label which fully endorses the use via hand held application equipment
• It is fast acting and controls a wide spectrum of weeds
• It moves to the roots ensuring high levels of long-term control
• Stock grazing can resume only 7 days after application (but longer if poisonous weeds such as ragwort are present)
• It is very good value for money – 16 knapsacks from each litre of product when mixed in 10 litre batches
• It is rainfast in only 2 hours and is very safe to grass

Use only through a knapsack or other hand held equipment, e.g. lance
The rate of application is 60 ml in 10 litres of water
Target weeds at the right size – young and actively growing is best. If you have topped the weeds first then wait 2-3 weeks for sufficient weed regrowth before spraying
Ensure your knapsack is properly maintained, clean and free of dirt with the nozzles able to deliver a consistent and even spray
Wear suitable protective clothing when handling and measuring the concentrate and whilst spraying – gloves, coveralls and rubber boots are essential
Spray until weed leaves are thoroughly wet, but stop before the spray runs off the leaves
Grazon® Pro is LERAP Category B, so spray must not fall within 1 metre of the top of the bank of a flowing or static water body. Spray must be aimed away from the water
Keep other people and pets out of treated areas for at least 2 hours until spray has dried on leaf
When spraying is finished, clean out the tank, spray lines and nozzle, making sure the washings go on a treated area. If the Grazon® Pro container is empty, rinse thoroughly 3 times with clean water and dispose of the rinsings on the treated area.
Optimum timing of application
Spray when actively growing but preferably before flowering (normally up to mid-June).
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
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.

Best Use Advice for Spot treatment with Grazon®Pro
· Grazon®Pro is a professional use product, therefore ensure all knapsack operators have necessary PA1 and PA6 qualifications
· Service and maintain knapsack sprayers regularly and calibrate before use

· Apply at the rate stated on the label – for Grazon®Pro this is 60 ml in 10 L water
