Specialist New RoundUp To Make The Most Of Grassland Re-Seeding

An advanced new Roundup has been introduced this season to help hard-pressed livestock producers across the UK make the most of their grassland improvement opportunities.

Roundup Biactive GL has been formulated to ensure the most complete old sward destruction, best long-term control of problem weeds and fastest re-seeding turn-around, explained Monsanto technical development manager, Barrie Hunt at the product’s launch in the West Midlands this week.

“We know re-seeding can boost annual pasture dry matter production by 60% or more,” he explained. “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. ”
 

In both these respects, Barrie Hunt is adamant that the new Roundup is just what grassland managers need to ensure they secure the greatest value for money from their pasture improvement efforts.

 At the launch, he pointed to extensive trials showing Roundup Biactive GL’s combination of 

360 g/l of glyphosate as a potassium salt and 125 g/l of a novel surfactant blend to be more reliable in controlling problem grass and broadleaved weeds under challenging conditions than a range of other generic formulations. 

He stressed that approval for spraying ahead of silage-making or grazing – backed by extensive research showing no effect on forage quality, harm to livestock or residues in meat or milk – gave the product a further major advantage.

“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,” said Barrie. “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 5-7 days before cultivation and sowing.

“So you can take a second silage cut or extra grazings off your old sward right up to the end of July and still re-seed at the early autumn timing that gives the best perennial weed control, rather than having to shut your ground-up for re-seeding from early June.

“What’s more, our new Roundup is rainfast in just one hour on annual grasses and couch, and four hours on perennial weeds and old swards; doesn’t need adjuvants with even the hardest water; has valuable in-built drift risk reduction properties; and carries a completely ‘clean’ hazard-free label for product use, handling, transport and storage.

 

“As well as having all the advantages for grassland re-seeding, it’s also approved for a broad range of other mixed farm uses” he added. “This includes pre-harvest application 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 cansfrom Monsanto distributors across the country for typical grassland usage rates of 2-6 l/ha depending on sward age and weed species.
