OBSERVATIONS ON NUFARM’S TERRAD’OR
brassicas, it’s a very good fit for that. It’s also very good on some of the tougher broad leaf weeds.

Terrad’or gives us a lot more than what our existing Group 14 chemistry ever gave us in terms of its efficacy on broadleaf weeds. It’s an interesting product given it falls into that Group 14 category, but it’s actually at the higher end of efficacy within that group. I found it was particularly good on brassica species - if you’re looking at another mode of action trying to get into some of the herbicide-resistant
The thing I really like about Terrad’or is the grass additive effect when we mix it with glyphosate products like CRUCIAL or our paraquat blends. That’s very appealing when you look at where we are with glyphosateresistant ryegrass. Over the years, we’ve steadily lost efficacy, so it’s very beneficial to have a product that gives you an additive effect and better efficacy on controlling ryegrass. It’s especially useful when we’re targeting ryegrass with the paraquat-type mixes – I’ve seen what a good fit it is and how effective it is.
I find the short plant-backs are really useful and I’ve used it a lot at sowing. We had a very good opportunity to do a lot of double knocks this year, going in with glyphosate early and then coming in with paraquat.
But if you’ve got broadleaf weeds that have re-emerged, obviously paraquat is going to struggle with that, particularly with some of the tougher species.
Terrad’or offers a really good package in this respect. Not only do we get control of those broadleaf weeds that are emerging just prior to sowing, we’ve got that additive effect with paraquat, so we’re getting very good grass knockdown as well. CRUCIAL is a really important product in this space, but I’m trying to rotate away from glyphosate where it’s appropriate, so being able to use Terrad’or with paraquat in summer is a really good fit as well.
An added bonus is that Terrad’or has been brought to market at a price point that’s appealing to growers. It’s good chemistry at an affordable price and it gives me a lot more flexibility when I’m advising growers.
