5L Selective Herbicide for Broadleaved Weeds
This systemic, penetrant selective herbicide is supplied in a 5L pack that treats up to 2.5ha. It controls many broad-leaved weeds, including daisies, dandelion and white clover, in managed amenity turf and amenity grassland such as golf courses, playing fields and sports pitches.
Key Features
- Selective control of broad-leaved annual and perennial weeds, including daisies, dandelion and white clover
- Two active substances with different modes of action, giving optimum efficacy and lowering the risk of herbicide resistance developing
- Taken up mainly through the foliage
- Works best when target weeds are small and actively growing
- Single application per year at 2l/ha
- Active substances: 98g/l fluroxypyr and 2.45g/l florasulam
How to Use
When to Use
Apply to actively growing grass between March and October (application window: Mar, Apr, May, Jun, Jul, Aug, Sep, Oct). Newly sown turf should be allowed to establish before treatment.

Applications
- Amenity grassland: semi-natural or planted grassland that receives minimal or non-intensive management, including airfields and mainly grassed railway embankments and roadside verges.
- Managed amenity turf: intensively managed turf that is mown frequently (at least once a week), including fields used for turf production. This may cover areas used by the public, including all kinds of sports turf, golf greens, tees and fairways.

Active Substances
Fluroxypyr
Mode of action: fluroxypyr is a synthetic auxin herbicide. Synthetic auxins trigger rapid, abnormal cell growth and development in the stems, petioles and leaves of susceptible plants, causing cells to burst and eventually killing the cells and the plant.
Mobility: as a systemic penetrant, it is moved down through the plant in the phloem (the sugar-conducting tissue) and up through the plant in the xylem (the water-conducting tissue).
Application timing: systemic auxins work best on actively growing weeds and are usually more effective on younger plants in their vegetative stages.
Resistance: resistance to synthetic auxins is still fairly uncommon, thought to be because the herbicide acts on multiple sites. Even so, resistance has been seen worldwide, with 36 species confirmed resistant as of 2017. Good practice, such as alternating with products that have a different mode of action and using cultural weed control, helps lower the risk of further resistance.
Florasulam
Mode of action: florasulam is an ALS (Acetolactate Synthase) inhibitor. Acetolactate synthase is a key enzyme in the production of branched-chain amino acids. ALS inhibitors block this process, so the plant first turns chlorotic, then its tissues become necrotic, and finally the whole plant dies.
Mobility: as a systemic penetrant, it is moved down through the plant in the phloem (the sugar-conducting tissue) and up through the plant in the xylem (the water-conducting tissue).
Application timing: ALS inhibitors work best on actively growing weeds and are usually more effective on younger plants in their vegetative stages.
Resistance: resistance to ALS inhibitors is relatively common because of their high activity on sensitive biotypes and their residual activity in soil. Good practice, such as alternating with products that have a different mode of action and using cultural weed control, helps lower the risk of further resistance.
Notes
- Do not let spray from horizontal boom sprayers fall within 5m of the top of the bank of a water body
- Do not let spray from hand-held sprayers fall within 1m of the top of the bank of a water body
- Clippings from treated grass may be used as mulch after the third cut
- Leave four weeks between application and re-seeding turf
- Do not apply when turfgrass is wet or stressed, when temperatures are low, or during long spells of cold or dry weather
- Avoid contact with non-target plants
- Do not mow for three days before and after application so the active substances are taken up as fully as possible
