Nufarm’s Terrad’or is already proving a success story across the country, less than two years since its launch.
Terrad’or is a 700 g/kg formulation of tiafenacil. Since launching in 2021, it’s gained a name as the next generation of Group 14 herbicides, thanks to its performance on notoriously hard-to-kill weeds.
It’s exciting news for Australian growers, according to André Sabeeney, Nufarm’s national technical lead who said Terrad’or is quite a recently established spike, but it’s already making a big impact on the market.
“It outperforms other Group 14 herbicides that have been around for a long time – growers are getting noticeably better, faster results compared to anything else they’ve used.
“It’s an excellent mix partner for all non-selective herbicides and it’s proving to be a valuable tool when it comes controlling problem weeds like marshmallow, sowthistle, wild radish and even annual ryegrass,” he said.
Mr Sabeeney said sowing into a clean paddock is key to getting good crop establishment and the reliance on glyphosate had seen a rapid rise in resistance in several cropping areas across Australia, and that growers were looking at alternative groups of chemistry to strengthen their programs.
“With excellent results across both broadleaf weeds and grasses, Terrad’or is giving growers the edge they need to assist in managing glyphosate resistance.
“We’ve invested a lot into numerous trials across multiple seasons and in-field conditions, and the label reflects that – Terrad’or has been registered to aid in the control of glyphosate resistance in ryegrass, for example.
“It also performs better than many other group 14 chemistries in controlling weeds like sowthistle that have known resistance to glyphosate and 2,4-D products.”
Prevention is always better than cure, and that’s where Terrad’or really shines, Mr Sabeeney said. “Rotating between chemistry groups with glyphosate (group 9) and paraquat (group 22) and adding an additional group such as Terrad’or (Group 14) enables growers to keep ahead of resistance before it becomes a problem.
“The ideal application is in combination with a double-knock control strategy, with either a glyphosate or a paraquat mix partner. This assists in management of resistance before it even becomes a major issue, and that’s where growers are seeing the best results – it helps make sure those resistant weeds never get established in the first place,” he said.
Mr Sabeeney said part of Terrad’or’s remarkable success was owed to the fact that it’s undergone rigorous field testing in Australian growing conditions.
“We’ve worked closely with Australian growers to deliver a Group 14 spike that meets their needs and their conditions. When it comes to weed control, the landscape is always changing.
“Growers are always looking for ways to grow and improve, and we need to keep improving alongside them. This is part of part of Nufarm’s commitment to Australian farmers.”
