Annual ryegrass is one of the biggest frustrations for our winter cereal crops, wouldn’t you agree? If you’re like most farmers, a big part of your ryegrass herbicide tool kit has been Sakura. And in the fight against resistance, we need to keep adding new weapons. Now, you can use Bayer’s new, more powerful, more flexible herbicide – Mateno Complete. Mateno Complete combines three active ingredients with different modes of action, including aclonifen, which is new to Australia. A residual option that provides timing flexibility to enable incredible performance in different scenarios. It can also be used early post-emergence to deliver control across the entire soil surface profile, plus be incorporated by sowing.
Late last year, Bayer got the registration through for using Mateno Complete on barley at 750ml/ha early post-emergent. This allows weed control across the complete soil surface profile, in furrow, on furrow shoulder and in the inter-row. As well as this, they were able to get control of Indian hedge mustards, volunteer canola, deadnettle, fumitory, mouse-ear chickweed, lesser loosestrife, wireweed and common sow thistle on the label at 1L/ha in wheat. Remember when applying EPE aiming for 1-2 leaf ryegrass is key, and a follow-up rain is also very important to wash the chemical into the soil.
What is it?:
Mateno consists of three active ingredients:
- Aclonifen (400g/L); – a whole new active for Australia. Aclonifen has foliar and soil activity and will have activity on both grasses and broadleaf weeds.
- Pyroxasulfone (100g/L); – which is the active in Sakura, and has soil activity on mainly grass weeds, and
- Diflufenican (66g/L); found in Brodal Options and a part of Tigrex, which has both soil and foliar activity on mainly broadleaf weeds.
Why should you be excited about Mateno Complete?
Because you have a fully-equipped weed arsenal all in one product.
It can be applied on both Wheat and Barley, targeting grass weeds – including annual ryegrass, barley grass, great brome, and wild oats, as well as broadleaf weeds – including wild radish, capeweed, and prickly lettuce.
Even more importantly, it has two application windows, IBS (incorporated by sowing) or EPE (early post-emergence). This gives you the flexibility of control depending on your unique weed situation.
What’s more, Mateno’s rates are simple.
For wheat, you can use 750ml-1L/ha – the 1L/ha rate is equal in Pyroxasulfone to 118g/ha of Sakura. You are limited to 750ml/ha in barley. The early post-emergence application will be aimed to take out 1-2 leaf ryegrass.
The best part? You’ll now be able to take out that ryegrass in the interrow, which is usually safe from pre-em chemistry.
4 key takeaways:
- Mateno has a new mode of action
- Suitable for wheat and barley
- Controls a broad range of grass and broadleaves, plus get long residual annual ryegrass control
- Flexible application timing: Apply incorporated by sowing (IBS) or early post-emergence (EPE) in wheat and barley.
Mateno is available in 100lt and 10lt pack sizes.

So far, it appears that when you are using Mateno as an early post-emergence application, it is best to have either a Triallate (Avadex) or Trifluralin upfront as a minimum to get control on at least 40-50% control on the ryegrass and then allowing the Mateno Complete to do the heavy lifting on the rest.
