Building on last year’s Irish launch, Casper® remains a standout option for farmers seeking reliable, flexible and broad-spectrum weed control, across both newly sown leys and established pasture.
Key account and business manager at Syngenta Margaret Murphy comments: “Casper® is a great addition to our product portfolio. We believe this product offers livestock farmers a strong option to control key weeds, which impact yield and quality of pastures.
“Very few herbicides will control a broad spectrum of weeds like docks, thistles, nettles and buttercup and we are delighted to now have this offering in our portfolio for Irish farmers to benefit.”
Proven performance where it matters most
Grassland weeds continue to significantly reduce yield potential on farm. If not controlled, they compete aggressively for nutrients, light and moisture, reducing both dry matter output and forage quality.
Casper® addresses this challenge through its unique dual-active formulation, combining Dicamba (500g/litre) – a well-established and trusted standard - and Prosulfuron (50g/litre) – bringing a new mode of action to grassland. This combination delivers a powerful balance of efficacy and crop safety, giving farmers confidence across a wide range of conditions.
Season-long weed control
Casper® delivers broad-spectrum weed control throughout the growing season, protecting yield potential early on, while maintaining the quality of the sward.
On newly sown leys, it effectively tackles common annual weeds such as chickweed, fat hen, fumitory, shepherd’s purse, nettles and thistles - helping young swards establish cleanly and compete strongly.
In established pasture, Casper® continues to perform, providing reliable control of more persistent problem weeds, including broad-leaved and curled dock, thistle, creeping buttercup and nettles.
This season-long flexibility makes it a practical all-round solution for farmers looking to maintain productive, high-quality grassland.
Flexibility that fits Irish farming systems
Irish grazing and silage systems demand flexibility and Casper® delivers with an extended application window from April through to October.
Approved for use in both newly sown and established grassland, it gives farmers the flexibility to apply Casper to grassland in a range of growing stages.
Providing long-term control of key problematic weeds, while allowing farmers to target weeds at their most susceptible growth stages, work around grazing rotations and silage cuts and make better use of suitable weather windows.
Driving grass growth and feed quality
Effective weed control maximises performance. By removing competitive species, Casper® helps to increase grass production, improve sward utilisation, enhance palatability for grazing livestock and support higher-quality silage production.
The result is a cleaner, more productive sward that delivers better returns from every hectare.
As with all herbicides, best practice is essential:
For best results, application should be made in good growing conditions, ideally between 10°C and 25°C, when vegetation is dry and weeds are actively growing.Observe a 21-day interval before grazing or cutting for silage/hay. Note: Casper® is not clover-safe.A valuable addition to the grassland toolbox.
With pressure on margins and increasing focus on efficiency, Irish livestock farmers are looking for solutions that deliver consistent, measurable results.
Casper® continues to prove itself as a dependable, flexible herbicide option, helping farmers take control of problem weeds and maximise the productivity of their grassland.
