Monsanto has launched a new Roundup herbicide product to help livestock farmers manage their grassland more effectively. The company says Roundup Biactive GL has been formulated to ensure complete old sward destruction, effective control long-term control of problem weeds and fast reseeding turnaround.
Barrie Hunt, technical development manager at Monsanto, claims that trials have found the combination of 360 g/l of glyphosate as a potassium salt and 125 g/l of a novel surfactant blend in Roundup Biactive GL makes it reliable in controlling grass and broadleaved weeds under challenging conditions. Mr Hunt states: “We know re-seeding can boost annual pasture dry matter production by 60% or more. At the same time, we know how much less productive grasses like Yorkshire fog, rough stalked meadow grass and creeping bent - as well as docks, thistles and other problem grassland weeds - can compromise sward output and quality.
“Unless all these are reliably controlled, they will seriously undermine the establishment and value of new swards, making re-seeding little more than a costly waste of time, effort and money in many cases. It’s equally important that re-seeding takes pastures out of production for the least possible time. Particularly so, with today’s intense pressure on margins. ”
Mr Hunt also points out that Biactive GL’s approval for spraying before silage making or grazing, backed by research that shows no effect on forage quality, livestock harm or residues in meat or milk, gives it another key advantage. He goes on: “You can silage or graze five days after spraying with Biactive GL then cultivate and drill your new seeds the next day, secure in the knowledge that even the toughest weeds have taken-up enough glyphosate to kill them. This cuts a good three weeks or more from the traditional approach of waiting for sufficient regrowth after utilisation to spray-off the old sward then a further five to seven days before cultivation and sowing.”
Roundup Biactive GL is rainfast in one hour on annual grasses and couch, and four hours on perennial weeds and old swards. It doesn’t need adjuvants for hard water, has valuable in-built drift risk reduction properties and carries a completely ‘clean’ hazard-free label for product use, handling, transport and storage. The herbicide is also approved for a broad range of other mixed farm uses, including pre-harvest applications for cereals and pulses; stubble treatment; cover and fodder crop destruction; clearing vegetation from ditches, ponds and river banks and general weed control around buildings, yards, tracks and fence-lines.
Roundup Biactive GL is available in 5 and 20 litre cans from Monsanto distributors across the UK for typical grassland usage rates of 2-6l/ha, depending on sward age and weed species.
