Recommending Forefront® T, Pharaoh™ & Halcyon®
Forefront T, Pharaoh and Halcyon are the best solutions for controlling weeds such as docks, nettles, thistles, buttercups, dandelions and ragwort. These products should only be applied to established grassland where cattle or sheep are grazed, due to herbicide residues being carried over into grass that is utilised for zero grazing, silage, hay or haylage. The resulting manure will affect sensitive crops if used as fertiliser.
As part of the authorisation of these products, we require that all advisors who recommend them complete the relevant stewardship training. This ensures that users receive the best advice from qualified IASIS advisers before application.
Manure Management
- DO NOT use these products on grass that will be cut for animal feed (i.e. fresh cut grass, silage, hay or haylage) as herbicide residues will carry over into the forage and unwanted growth effects can result if this manure is applied to sensitive crops like potatoes or tomatoes in a green house. The graphic shows the do’s and don’t’s.
- Treated grass must not be cut for animal feed (i.e. fresh cut grass, silage, hay or haylage) in the calendar year of treatment.
- Animal feed (i.e. fresh cut grass, silage, hay or haylage) produced from the treated area after an interval of 12 months, must stay on farm and manure from animals fed on this must stay on farm and be spread only onto agricultural grassland.
- DO NOT apply to flower-rich grassland. Cattle and sheep which have grazed treated grassland must graze non treated grassland for 3 days prior to grazing flower rich grassland.
Ragwort control
- Those products particularly effective on Common ragwort ( > 90% control). Common ragwort (Senecio jacobaea) tends to be found on poorer quality pastures. It is normally a biennial plant. A rosette in its first year that in its second year sends up one or more leafy unbranched stems that usually extend to 30-90 cm high.
Application timing is crucial to achieve good levels of control. It is recommended to spray Common ragwort at the rosette stage, up to but before stem extension, when it is growing actively.
- Livestock must be kept out of the treated area until treated Ragwort has died and completely rotted down.
Re-seeding intervals
- Weed removal can lead to bare patches which may require over-seeding.
- Where over-seeding is necessary then our guidance on reseeding intervals for a range of plant species typically found in multi-species swards is shown here:
| Species | Re-seeding interval |
|---|---|
| Grass | 1 month |
| White clover | 4 months |
| Red clover | 4 months |
| Plantain | 4 months |
| Chicory | 4 months |
