Product Benefits
- Can be applied via a handheld sprayer
- Controls a wide spectrum of weeds
- Low application rate offers excellent value
- Rainfast in just 2 hours
Instructions for use
Where to use
Grazon Pro can be used in all amenity grassland and grassland situations.
- Amenity grassland: Areas of semi-natural or planted grassland subject to minimal or non-intensive management
- Grassland: Land grown for grass production which may be grazed and/or cut for animal consumption
When to use
Grazon Pro can be used between 1st March to 30th October and is most effective when used to treat weeds that are actively growing.

For optimum efficacy, the timing of the application of Grazon Pro is crucial:
| Weed Type | Application Timing |
|---|---|
| Nettle | When actively growing but before flowering |
| Dock | In the spring when docks are in the rosette stage |
| Creeping thistle | When actively growing but before flower spikes are 15 cm high |
| Bramble, broom and gorse | June-August when actively growing but before autumn senescence begins |
How to use
Grazon Pro can be applied using handheld spraying equipment such as a knapsack sprayer using a medium spray quality nozzle:
- Half fill the spray tank with water
- Add the required amount of Grazon Pro and agitate to ensure thorough mixing
- Add the remaining water and continue to agitate
- Maintain agitation of the spray solution whilst spraying
- When spraying ensure foliage is thoroughly wetted but run-off should be avoided
- To allow maximum translocation, avoid cutting the grass for up to 28 days after application
- After spraying clean all spraying equipment inside and out, using a suitable spray tank cleaner
Additional Information
- Do not apply onto or around manure or other compost heaps
- Do not roll or harrow grass for 10 days before or 7 days after application
- Any yellowing of the sward is transient and will quickly grow out
- Avoid contact with non-target plants, ponds, lakes or water courses
- In hot conditions vapour drift may occur
- Grazon Pro residues in plant tissues (including manure and compost) which have not completely decayed may affect succeeding susceptible crops
- Do not use plant material treated with Grazon Pro or manure from animals fed on crops treated with Grazon Pro for composting or mulching
- Be aware that conifers are particularly sensitive to spray drift
- Avoid applying when conditions are not suitable for active plant growth
- Exclude livestock during treatment and for at least 7 days following treatment, if ragwort is present exclude livestock until it has completely recovered or died and there is no visible sign of the dead weed
Active Substances
Clopyralid and triclopyr
Bio-Chemical Mode of Action: Clopyralid and triclopyr belong to the synthetic auxins group of herbicides.
Synthetic auxins work by inducing rapid abnormal cell growth and development in the stems, petioles and leaves of susceptible plants causing cell bursts and ultimately cell and plant death.
Mobility: Clopyralid and triclopyr are systemic penetrants which means that the active substance can be translocated downwards through the plant within the phloem (sugar conducting tissues) and upwards through the plant within the xylem (water conducting tissues).
Application timing: Systemic auxins are best applied when the weeds are actively growing. They are generally more effective when target plants are younger and in their vegetative phases.
Resistance: The incidences of resistance to synthetic auxins remains relatively low which is assumed to be because the herbicide has multiple sites of action.
However, resistance to synthetic auxins has been observed globally with 36 species being confirmed as resistant as of 2017. Best management practices, such as alternating with products with a different mode of action and using cultural weed control methods, will help to reduce the risk of further resistance.
