Get ahead of turf weeds with new herbicide from Syngenta
2 June 2021
Clean out broad-leaved weeds in turf grass with the new herbicide, Overtake, from Syngenta.
Now available for golf course and sports turf management in Ireland, the unique combination of two herbicide actives gives consistently reliable results in more variable spring conditions, against a wide spectrum of problematic weeds.
Syngenta application trials have shown optimum results with treatment at a water volume of just 200 l/ha, giving significant savings in time and reduced interruption in play, compared to herbicide treatments typically applied at 400 l/ha or more.
Syngenta technical manager, Glenn Kirby, reported Overtake has shown outstanding turf safety in more than 70 trials across nine countries. In the UK, STRI recorded no adverse phytotoxic effects across 19 cultivars of all key cool-season turf grass species, even at more than double recommended application rate.
“Weeds compete with turf for light, moisture and nutrients,” said Kirby. “Removing weed competition early in the season ensures more of the inputs you put on are better utilised for turf growth – creating stronger more resilient turf and better playing conditions.”
Overtake targets most of the problematic broad-leaved weeds in turf grass. Early treatment in the spring enables vigorous turf recovery to fill gaps and minimise risk of weed reinvasion.
“In addition to greater reliability in a wider range of temperatures and conditions, the two different modes of action in Overtake reduces the risk of weed resistance developing,” added Kirby. Overtake is a Syngenta optimised formulation to target broad-leaved weeds.
To get the best from Overtake, it should be applied in spring when weeds are actively growing and the leaves are dry. Treatment should be made at a rate of 2.0 l/ha, applied in 200 l/ha water volume, using XC025 or XC04 nozzles to better target the leaf area and minimise risk of drift. Turf should be left for three days after application before mowing.
Colman Warde, ICL country manager for Ireland, which will be distributing Overtake added: “This is the third exciting new turf product for Ireland from Syngenta in recent months, following on from the launch of Ascernity fungicide and Hicure biostimulant.
“The commitment to R&D investment in turf is crucial to give us a full range of options for a truly Integrated Turf Management approach, incorporating all aspects of the ICL portfolio. Combined with Turf Rewards to access turf management tools, it is a really compelling offer for superintendents and sports turf managers.”
