The trials showed that lines treated with Syngenta’s Primo Maxx retained line visibility for up to 50% longer.
By mixing the turf growth regulator with line marking paint, turf managers were able to suppress grass growth for up to six weeks and better retain line colour.
Primo Maxx has been approved for use as a pre-mix with paints for both wheel-to-wheel application and spray line marking applicators. It is recommended that Primo Maxx be used at a rate of 2 ml per litre of line marking paint.
Syngenta’s Rod Burke said: "At the end of the season, the turf simply reverts out of regulation with no damage or lasting effects.
"There is no cost or effort of re-seeding, no bare soil for weeds to establish and, if sports turf is being used for another event over the summer, new lines can be quickly and easily put in place."
