A selective herbicide for season long control on over 60 species of broadleaf weeds in established grassland, helping you get the job done effectively and efficiently. Advanced chemistry puts Forefront in a class of its own when it comes to weed control.With its systemic mode of action and residual activity, one application has a lasting effect on pastures. When applied moves quickly throughout the entire target plant, going deep into the root system. Because it is readily translocated, Forefront controls the entire plant, not just the part above ground. Forefront is not a clover safe product, and is advised for use on grazing pastures only. WARNING: Manure from animals grazed on Forefront treated grassland should not leave the farm. Apply to grassland 7-10 days before grazing. Pack size 2l (treats 2.5 litres).
