Selective Grassland Herbicide 1L – Triclopyr & Clopyralid for Docks, Thistles, Nettles & Brambles (MAPP 19875)

A professional selective herbicide for amenity grassland and grassland (MAPP 19875). It is a highly effective systemic penetrant with contact action, containing 240g/l triclopyr and 60g/l clopyralid, and treats a wide range of broad-leaved weeds. It gives excellent control of tap-rooted weeds such as docks and spear thistle, as well as other problem weeds including nettles, brambles, broom and gorse.

Key Features

• Authorised for application with handheld sprayers, so problem weeds can be targeted accurately
• Controls a wide spectrum of broad-leaved weeds
• Low application rate offers excellent value
• Rainfast in just 2 hours
• Ideal for permanent pasture and for grass that is cut infrequently, such as golf roughs
• Spot treat problem weeds at 60ml of product to 10 litres of water

Product Overview

How to Use

Where to use

It can be used in all amenity grassland and grassland situations:

• Amenity grassland: areas of semi-natural or planted grassland under minimal or non-intensive management.
• Grassland: land grown for grass production, which may be grazed and/or cut for animal consumption.

When to use

Apply between 1st March and 30th October. It works best on weeds that are actively growing, and the timing of application is crucial for the best results:

How to apply

Apply with handheld spraying equipment, such as a knapsack sprayer, fitted with a medium spray quality nozzle:

1. Half fill the spray tank with water.
2. Add the required amount of herbicide and agitate to mix thoroughly.
3. Add the remaining water and continue to agitate.
4. Keep agitating the spray solution while spraying.
5. Wet the foliage thoroughly, but avoid run-off.
6. Do not cut the grass for up to 28 days after application, to allow maximum translocation.
7. After spraying, clean all spraying equipment inside and out with 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 temporary and will quickly grow out.
• Avoid contact with non-target plants, ponds, lakes and watercourses.
• Vapour drift may occur in hot conditions; conifers are particularly sensitive to spray drift.
• Residues in plant tissues (including manure and compost) that have not fully decayed may affect following susceptible crops, so do not use treated plant material, or manure from animals fed on treated crops, for composting or mulching.
• Avoid applying when conditions are not suitable for active plant growth.
• Keep livestock out during treatment and for at least 7 days afterwards. If ragwort is present, keep livestock out 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 auxin group of herbicides. Synthetic auxins cause rapid, abnormal cell growth and development in the stems, leaf stalks and leaves of susceptible plants, making cells burst and ultimately killing the plant.

Mobility: both are systemic penetrants, so they are carried downwards through the plant in the phloem (sugar-conducting tissues) and upwards in the xylem (water-conducting tissues).

Application timing: synthetic auxins work best on actively growing weeds and are generally more effective on younger plants in their vegetative phase.

Resistance: resistance to synthetic auxins remains relatively low, thought to be because they have multiple sites of action. Even so, resistance has been seen worldwide, with 36 species confirmed resistant as of 2017. Alternating with products that have a different mode of action and using cultural weed control methods will help reduce the risk of further resistance.
